This application is based on and claims priority to Chinese Patent Application No. CN201610978818.X, filed on Nov. 7, 2016, which is incorporated herein by reference in its entirety.
The present disclosure generally relates to a vehicle terminal capable of affecting engine start-stop functionality in vehicles, and more particularly, to methods, apparatuses, and systems for launching an engine start-stop function based on traffic-related information.
With the development of improved automobile manufacturing technologies, new cars can be equipped with engine start-stop functionality. The engine start-stop capability of a vehicle allows, when a brake pedal is pressed to stop the vehicle, an engine of the vehicle to be stopped (i.e., partially or entirely shut off) to save fuel. When stopped, lubricating oil inside the engine may continue to run to keep the engine lubricated. When the brake pedal is released or a clutch depressed, the engine may start again (i.e., the engine may be fired up) so the vehicle can proceed. Although circulating lubricant inside the engine can prevent damage to the engine during normal operations, frequent starts and stops that are too frequent could introduce additional wear and tear over time and potentially use more fuel than would otherwise be used. Moreover, although the engine can be started relatively quickly, there can be a small delay between the time the brake is released and the time the engine restarts to move the vehicle again. Consequently, if the vehicle start-stop function is launched every time the vehicle comes to a stop, even if the vehicle will only remain stopped for a very short time (say, a few seconds), the start-stop functionality may be undesirable.
In the related art, when a user encounters a traffic light or congestion while driving, the user will press the brake pedal, and a vehicle terminal automatically launches the engine start-stop function after detecting that the vehicle is in a stop state (e.g., has come to a stop), thereby turning the engine off. This occurs without consideration for how long the vehicle is expected to remain stopped before needing to start again.
In view of the related art, example methods, apparatuses, and systems for launching an engine start-stop function are provided in the disclosure.
In a first aspect, a method may be implemented in a vehicle terminal of a vehicle, for launching an engine start-stop function in the vehicle. The method may include: transmitting, from the vehicle terminal to a server, a traffic information acquiring instruction which carries current location information of the vehicle, the traffic information acquiring instruction and current location information being used by the server to acquire traffic information for a road on which the vehicle is located currently as determined based on the current location information, the traffic information indicating a current traffic condition corresponding with traffic flow on the road; receiving, at the vehicle terminal, the traffic information transmitted by the server; and launching the engine start-stop function for the vehicle when the traffic information meets a preset condition, the preset condition corresponding with a period of time during which the vehicle is anticipated to remain stopped based on the traffic information, the start-stop function configured to stop the engine while the vehicle is stopped and restart the engine when the vehicle is to move again.
In a second aspect, an apparatus for launching an engine start-stop function in a vehicle, comprises: a first transmission module configured to transmit to a server a traffic information acquiring instruction which carries current location information of the vehicle, the traffic information acquiring instruction used by the server to acquire traffic information for a road at which the vehicle is located currently as determined based on the location information, the traffic information indicating a current traffic condition for the road; a first reception module configured to receive traffic information transmitted by the server; and a launch module configured to launch the engine start-stop function for the vehicle when the traffic information satisfies a preset condition, the preset condition corresponding with a period of time during which the vehicle is anticipated to remain stopped based on the traffic information, the start-stop function configured to stop the engine while the vehicle is stopped and restart the engine when the vehicle is to move again.
In a third aspect, a computer-readable medium has instructions thereon that when executed cause a vehicle terminal to: transmit to a server a traffic information acquiring instruction which carries current location information for a vehicle, the traffic information acquiring instruction used by the server to acquire traffic information of a road at which the vehicle is located currently as determined based on the location information, the traffic information indicating current traffic condition of the road; receive the traffic information transmitted by the server; and launch an engine start-stop function for the vehicle when the traffic information satisfies a preset condition, the preset condition corresponding with a period of time during which the vehicle is anticipated to remain stopped based on the traffic information, the start-stop function configured to stop the engine while the vehicle is stopped and restart the engine when the vehicle is to move again.
It is to be understood that both the forgoing general description and the following detailed description are exemplary and illustrative only, and will not limit the present disclosure.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the invention and, together with the description, serve to explain the principles of the invention.
Exemplary embodiments are described in detail herein, example implementations of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which same numbers in different drawings represent same or similar elements unless otherwise described. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses, systems, and methods consistent with aspects related to the invention as recited in the appended claims.
An application scenario of the present disclosure is described before detailing example embodiments of the present disclosure. With the development of automobile manufacturing technologies, currently most new cars have engine start-stop functionality. The vehicle terminal may launch (i.e., engage, enable, activate, implement, etc.) the engine start-stop function when the brake pedal is detected to be pressed by the user to stop the engine because of, for example, a red traffic light or road congestion (i.e., anything affecting traffic flow or in the path of the vehicle, such as other vehicles, construction equipment, pedestrians, bicyclists, etc.) while the vehicle is being driven. In practice, when there is a traffic light or road congestion while the vehicle is running, the waiting time at a red light or the waiting time for the road congestion may be relatively short. Therefore, the user may not want the engine start-stop function to be launched to thereby stop the engine until the vehicle is to move again. The vehicle terminal may nonetheless launch the engine start-stop function once the brake pedal is detected to be pressed, which may annoy the user, may be inefficient, and/or may be harmful to the engine over time. In order to address the problem, the vehicle terminal may, in example implementations, transmit a traffic information acquiring instruction (e.g., a request for traffic information) to a server (which may be any networked computing device or devices). The server may acquire (i.e., obtain, retrieve, or otherwise access from, for example, other devices, memory, databases, etc.) traffic information for a road (or segment thereof) or otherwise the vicinity at which the vehicle is located currently after receiving the traffic information acquiring instruction, and the server may transmit the acquired traffic information to the vehicle terminal. The vehicle terminal may determine whether to launch the engine start-stop function based on the traffic condition of the road at which the vehicle is located currently.
In
In 201, a traffic information acquiring instruction is transmitted to a server by a vehicle terminal. In various implementations, the traffic information acquiring instruction may be transmitted, for example, when the vehicle has already come to a complete stop, when the vehicle has a deceleration value greater than a threshold (e.g., when the vehicle is reducing speed quickly and may thus be coming to a stop), when the vehicle is decelerating while traveling at a speed that is below a threshold value (e.g., when the vehicle is slowing down when going relatively slowly, such as below 10 miles per hour (mph), suggesting the vehicle may be coming to a stop), when the vehicle is decelerating while traveling on a road with a density of traffic lights exceeding a threshold (e.g., when traffic lights are abundant on a road and the vehicle is slowing down, suggesting the vehicle may be coming to a stop because of a red light), or at other times deemed suitable to receiving information useful to determining whether to launch the engine start-stop function. The traffic information acquiring instruction may carry (i.e., include, be accompanied by, identify, etc.) current location information for a vehicle corresponding to (operating with) the vehicle terminal. The traffic information acquiring instruction may be used by (i.e., executed or otherwise acted upon by) the server to acquire traffic information for a road at which the vehicle is located currently (as determined from the location information). The traffic information may indicate/inform about current traffic conditions on the road. The traffic condition may be based on any factors affecting congestion, delays, and/or vehicle flow, such as the number and speed of vehicles, number and stop-time of traffic lights (e.g., how long cars are stopping at red lights), construction, accidents, broken-down vehicles, weather-related factors (such as floods and storms), etc.
In 202, the traffic information transmitted by the server is received at the vehicle terminal.
In 203, the engine start-stop function for the vehicle is launched when the traffic information meets/satisfies a preset condition (such as a traffic condition).
According to one or more embodiments of the disclosure, the vehicle terminal may transmit a traffic information acquiring instruction to the server to acquire the traffic information of a road at which the vehicle is located currently, receive the traffic information, and then launch the engine start-stop function for the vehicle when the traffic information meets the preset condition. As a result, the vehicle terminal may determine whether to launch the engine start-stop function based on a traffic condition of the road at which the vehicle is located currently, and thus it can avoid launching the engine start-stop function too frequently within a short period, since the start-stop function would otherwise automatically be launched once the brake pedal is detected to be pressed without consideration for the traffic information. Therefore, the engine start-stop function is more convenient, efficient, and/or user-friendly, and the user would be more willing to use the engine start-stop function, and thus usage and operation of the engine start-stop function is improved.
Optionally, the method may further include: detecting a current state of the vehicle; and acquiring a current location information of the vehicle when it is detected that the current state of the vehicle is in a stop state. Other states include deceleration exceeding a threshold (optionally, in combination with a sufficiently low speed), indicating the vehicle is likely coming to a stop.
Optionally, the traffic information may be current traffic light information for location of a traffic light at which the vehicle is located. The traffic light information may be based on, for example, how long a specific traffic light stays red by programming (e.g., the light may be programmed to remain red for two minutes at a time), how long the traffic light has been staying red within a recent period (such as the previous 15 minutes) due to current traffic conditions, etc. Launching the start-stop function for the vehicle when the traffic information meets the preset condition may include: determining waiting time at a red light for the vehicle continuing to wait at the red light at the location of the traffic light based on the current traffic light information; and launching the start-stop function for the vehicle when the waiting time at the red light is longer than a preset threshold (such as 15 seconds, 30 seconds, 1 minute, etc.).
Optionally, the traffic information may be real time road condition information for the road (or segment thereof) at which a vehicle is located. Launching the start-stop function for the vehicle when the traffic information meets the preset condition may include: determining congestion time (e.g., delay time, wait time, etc.) for the road or traffic congestion index for the road based on the real time road condition information for the road; and launching the start-stop function for the vehicle when the congestion time is greater than a preset threshold, and/or when the traffic congestion index satisfies a preset index condition. The congestion index may be a measure or classification corresponding with traffic levels. This may be based on, for example, current or historical values for average delays, average speed relative to speed limit, number of vehicles relative to vehicle capacity for the road (which may take into account whether the vehicles are large trucks that tend to cause greater delay because of their size and speed relative to passenger vehicles) density of traffic lights in a segment of the road, time of day (e.g., time corresponding with “rush hour” or peak congestion times), whether driving conditions are “stop and go” (with only brief stops, which may be too brief to justify launching the engine start-stop function), etc.
In 301, a traffic information acquiring instruction transmitted by the vehicle terminal is received by the server. The traffic information acquiring instruction may carry current location information for the vehicle corresponding to the vehicle terminal.
In 302, the traffic information of the road at which the vehicle is located currently is acquired based on the location information. The traffic information may indicate current traffic conditions for the road.
In 303, the traffic information is transmitted to the vehicle terminal. The traffic information may be used by the vehicle terminal to determine whether to launch the engine start-stop function for the vehicle.
According to one or more embodiments of the disclosure, the server may receive the traffic information acquiring instruction from the vehicle terminal, acquire the traffic information of the road at which the vehicle corresponding to the vehicle terminal is located currently based on the location information in the traffic information acquiring instruction, and transmit the acquired traffic information to the vehicle terminal. The traffic information is preferably “live” (i.e., updated as changes occur), but if live information is not available, the traffic information may be based on historical traffic levels, for example, at the time of day, around special events (e.g., a traffic light at a stadium around start or end time for a sporting event is likely to have higher delays than when there is no event at the stadium), etc. As a result, the vehicle terminal may determine whether to launch the engine start-stop function based on the traffic information, and thus it can avoid launching the start-stop function too frequently within a short period since the start-stop function would otherwise automatically launch once the brake pedal is detected to be pressed regardless of traffic information. Therefore, it is convenient for the user to use the start-stop function and the user would be more willing to use the start-stop function, and thus usage and operation of the start-stop function is improved.
Optionally, the traffic information may be current traffic light information for location of a traffic light at which the vehicle is located. Acquiring the traffic information for the road at which the vehicle is located currently based on the location information may include: determining the location of the traffic light at which the vehicle is located based on the location information; and acquiring the current traffic light information (which may include the amount of time the traffic light is currently, or has been recently, remaining red) for the location of the traffic light.
Optionally, the traffic information may be real time road condition information for the road. Acquiring the traffic information of the road at which the vehicle is located currently based on the location information may include: determining the road at which the vehicle is located currently based on the location information; and acquiring the real time road condition information of the road.
In 401, the vehicle terminal detects a current state of the vehicle corresponding to the vehicle terminal, and acquires the current location information of the vehicle when the vehicle terminal has detected that the current state of the vehicle is a stop state (e.g., the vehicle has come to a complete stop).
The vehicle terminal may detect the current state of the vehicle by detecting current running speed of the vehicle or by determining whether the vehicle is in an idle state (e.g., the vehicle is in neutral). It may be determined that the vehicle is in a stop state when it is detected that the current running speed of the vehicle is zero or the vehicle is in an idle state. When the vehicle terminal detects that the current state of the vehicle becomes a stop state, the vehicle terminal may acquire the current location information of the vehicle through on-board GPS (Global Positioning System). The location information may be longitude and latitude of the current location or information about the road at which the vehicle is located currently. Also, the location information may be other information which may indicate the current location of the vehicle. The location information may include, for example, addresses, intersections, mile markers, etc.
In 402, the vehicle terminal transmits to the server the traffic information acquiring instruction which carries the current location information of the vehicle corresponding to the vehicle terminal.
In 403, the server receives the traffic information acquiring instruction transmitted by the vehicle terminal.
In 404, the server acquires the traffic information for the road at which the vehicle corresponding to the vehicle terminal is located currently based on the current location information of the vehicle. The traffic information may indicate current traffic condition of the road.
The traffic information may be the current traffic light information for the location of the traffic light at which the vehicle is located. Or, the traffic information may be real time road condition information for the road at which the vehicle is located currently. The real time road condition information may indicate, for example, the degree of congestion (such as delay times) for the road at which the vehicle is located currently.
In the case that the traffic information is the current traffic light information for the location of the traffic light at which the vehicle is located, the operation 404 may include: determining running/travel direction of the vehicle; determining the location of a traffic light through which the vehicle is going to pass (once the light turns green) based on the current location information and the running direction of the vehicle, the location of the traffic light through which the vehicle is going to pass being the location of the traffic light at which the vehicle is located currently; and acquiring the current traffic light information for the location of the traffic light at which the vehicle is located currently based on the location of the traffic light at which the vehicle is located currently.
Prior to operation 404, the server may receive at least two current locations of the vehicle transmitted by the vehicle terminal, and determine the running direction of the vehicle based on the at least two current locations. The two current locations may include a first location determined at a first time, and a second location determined at a second time that is a brief period (such as 5 seconds) after the first time. Alternatively, the vehicle terminal may transmit a starting location and a target location to the server while the vehicle is running in order to request the server to plan a travel route for the vehicle, so that the server may determine the running direction of the vehicle based on the direction of travel required to get from the starting location to the target location of the vehicle. (This planning may also include determining, for example, the traffic light density and delay times for the travel route for use in deciding whether the engine start-stop function should be launched.)
The traffic light information may be remaining time for a red light for the vehicle waiting at the red light at the location of the traffic light, or may be start time and end time of current state (e.g., red light) of the traffic light at the location of the traffic light.
There may be a plurality of traffic lights for a plurality of lanes at the location of the traffic light. For example, there may be a traffic light for a through lane, a traffic light for a left-turn lane, and a traffic light for a right-turn lane. Thus, the acquired current traffic light information may include current traffic light information for multiple lanes at the location of the traffic light, or may be current traffic light information for the particular lane at which the vehicle is located currently.
If acquiring the current traffic light information for the lane at which the vehicle is located is impractical, the lane at which the vehicle is located may be deduced based on the location of the traffic light at which the vehicle is located currently, and then the traffic light information corresponding to the lane may be extracted from the current traffic light information (e.g., which lights are currently red and which are green), for the location of the traffic light. For example, if it is determined that a left-turn light is the only one that is red, and if the vehicle is stopped at that intersection, it may be deduced that the vehicle is likely stopped at the left-turn light, and the determination of whether to launch the engine start-stop function may be based on, for example, the remaining red time for the left-turn light.
The server may store traffic light information for various locations of traffic lights for various roads. Moreover, the stored traffic light information may change in real time. Alternatively, a traffic command server, rather than the server, may store the traffic light information for various locations of traffic lights for various roads. Moreover, the stored traffic light information in the traffic command server may change in real time.
Accordingly, the server may acquire traffic information for the road where the vehicle is located currently from the traffic light information for various locations of traffic lights stored therein based on the current location information of the vehicle. Alternatively, the server may acquire traffic information for the road where the vehicle is located currently from the traffic light information for various locations of traffic lights stored in the traffic command server based on the current location information of the vehicle.
Furthermore, the remaining time of red light for the vehicle waiting at the red light at the location of the traffic light may be the remaining time of red light for the lane at which the vehicle is located currently acquired, or may be the remaining time of red light for various lanes at the location of the traffic light acquired.
The operations to acquire the remaining time of red light for the lane at which the vehicle is located currently may be performed as follows, in various implementations. The lane at which the vehicle is located may be determined based on the location of the traffic light at which the vehicle is located currently, and then the remaining time of red light corresponding to the lane may be extracted from the current traffic light information for the location of the traffic light.
The operations to acquire the remaining time of red light for the various lanes at the location of the traffic light may be performed as follows, in various implementations. The current traffic light state of various lanes at the location of the traffic light may be determined based on the location of the traffic light at which the vehicle is located currently. The state of the traffic light may include red light state, yellow light state, green light state, and flashing-yellow light state. Then the remaining time of red light for a lane that is in the red light state may be acquired among the various lanes.
Furthermore, start time and end time for the current state of the traffic light at the location of the traffic light may be the start time and the end time of the current state of the traffic light for the lane where the vehicle is located currently acquired, or may be the start time and the end time of the current state of the traffic lights for various lanes at the location of the traffic light acquired.
The operations to acquire the start time and the end time of the current state of the traffic light for the lane where the vehicle is located currently may be performed as follows, in various implementations. The lane where the vehicle is located may be determined based on the location of the traffic light where the vehicle is located currently. Then the start time and the end time of the current state of the traffic light corresponding to the lane may be extracted from the current traffic light information for the location of the traffic light.
The operations to acquire the start time and the end time of the current state of the traffic lights for various lanes at the location of the traffic light may be performed as follows, in various implementations. The current state of the traffic lights for various lanes at the location of the traffic light may be determined based on the location of the traffic light where the vehicle is located currently. The state of the traffic lights may include red light state, yellow light state, green light state, and flashing-yellow light state. Then the start time and the end time of the current state of the traffic lights for the various lanes may be acquired.
In the case that the traffic information is the real time road condition information of the road at which the vehicle is located currently, the operation 404 may include: determining the road where the vehicle is located currently based on the location information; and acquiring the real time road condition information of the road.
The real time road condition information of the road may include estimated passing time when the road is congested, and historical passing time when the road is clear. Alternatively, the real time road condition information of the road may include traffic congestion index of the road, or congestion time of the road, which may be the difference between the estimated passing time and the historical passing time.
In operation 404, the server may acquire the real time road condition information of the road from a third party server based on the road where the vehicle is located currently. The third party server may be a server which may provide map service or monitor road conditions in real time. For example, the third party server may be a map server or a traffic command server. The traffic command server may be used by the authorities to monitor the road condition in real time.
In 405, the server transmits the traffic information to the vehicle terminal.
In 406, the vehicle terminal receives the traffic information transmitted by the server.
In 407, the vehicle terminal launches the engine start-stop function for the vehicle when the traffic information meets the preset condition.
The vehicle terminal may determine whether the traffic information meets the preset condition after receiving the traffic information transmitted by the server. When the traffic information meets the preset condition, the engine start-stop function for the vehicle is launched. When the traffic information does not meet the preset condition, the engine start-stop function for the vehicle is not launched (i.e., disengaged, disabled, deactivated, not implemented, etc.).
Optionally, in the case that the traffic information is the current traffic light information for the location of the traffic light where the vehicle is located, the operation 407 may include: determining the waiting time at a red light for the vehicle continuing to wait at the red light at the location of the traffic light based on the current traffic light information; and launching the engine start-stop function for the vehicle when the waiting time at the red light is greater than a preset threshold.
Below are several example implementations to determine the waiting time at a red light for the vehicle continuing to wait at the red light at the location of the traffic light based on the current traffic light information. It is noted that anticipated wait times (i.e., the length of time during which the vehicle is expected to remain stopped) may be affected by other factors, such as proximity to the red light. For example, the farther away a vehicle is from an intersection when stopped because of a red light, the greater the potential delay, as other vehicles ahead must start moving once the light turns green before the user's vehicle can start moving as well. These other factors may also be taken into account in deciding whether to launch the engine start-stop function.
In a first example implementation: if the traffic light information includes the remaining time of red light for the lane where the vehicle is located currently, the remaining time of red light may be used as the waiting time at a red light for the vehicle continuing to wait at the red light. If the wait time is less than a threshold, it may be determined that the vehicle will be stopped for too brief of a time to justify launching the engine start-stop function.
In a second example implementation: if the traffic light information includes respective remaining time of red light for various lanes at the location of the traffic light, the vehicle terminal may locate the lane where the vehicle is located currently based on the location information, determine location using, for example, sensors that detect surroundings, or acquire the lane where the vehicle is located currently based on a selection by the user, and determine the remaining time of red light for the lane where the vehicle is located currently as the waiting time at the red light for the vehicle continuing to wait at the red light.
The third example implementation: if the traffic light information includes the start time and the end time of the current state of the traffic light for the lane where the vehicle is located currently and the current state of the traffic light is in a red light state, the vehicle terminal may calculate the remaining time of the current state of the traffic light based on current time, the start time, and the end time of the current state of the traffic light, and determine the remaining time as the waiting time at a red light for continuing to wait at the red light. For example, if the current time is 12:08 and the end time is 12:10, it may be determined that the remaining wait time is two minutes.
The fourth example implementation: if the traffic light information includes the start time and the end time of the current state of the traffic lights for various lanes at the location of the traffic light and the current state of the traffic lights is in red light state, the vehicle terminal may locate the lane where the vehicle is located currently based on the location information, determine location using, for example, sensors that detect surroundings, or acquire the lane where the vehicle is located currently based on a selection by the user, acquire the start time and the end time of the traffic light for the lane where the vehicle is located currently, subsequently calculate the remaining time of the current state of the traffic light for the lane where the vehicle is located currently based on the current time, the start time, and the end time of the current state of the traffic light for the lane, and determine the remaining time as the waiting time at a red light for continuing to wait at the red light.
Optionally, in the case that the traffic information is the real time road condition information of a road, the operation 407 may include: determining the congestion time of the road or the traffic congestion index of the road based on the real time road condition information of the road, and launching the start-stop function for the vehicle when the congestion time is greater than a preset threshold or the traffic congestion index satisfies a preset index condition.
If the real time road condition information includes the estimated passing time when the road is congested and the historical passing time when the road is clear, the vehicle terminal may calculate the difference between the estimated passing time and the historical passing time, determine the calculated difference as the congestion time of the road, and launch the engine start-stop function for the vehicle when the congestion time is greater than the preset threshold.
Optionally, in the case that the real time road condition information includes the traffic congestion index of the road, the vehicle terminal may determine whether the traffic congestion index is greater than the preset index and launch the start-stop function for the vehicle when the traffic congestion index is greater than the preset index.
Optionally, in the case that the real time road condition information includes the congestion time of the road, the vehicle terminal may directly determine whether the congestion time is longer than the preset threshold and launch the start-stop function for the vehicle when the congestion time is longer than the preset threshold.
According to example embodiments of the disclosure, the vehicle terminal may transmit a traffic information acquiring instruction to the server; the server may acquire the traffic information of the road at which the vehicle corresponding to the vehicle terminal is located currently after receiving the traffic information acquiring instruction, and transmit the acquired traffic information to the vehicle terminal. As a result, the vehicle terminal may determine whether to launch the start-stop function based on the traffic condition of the road at which the vehicle is located currently, and thus it can avoid launching the start-stop function too frequently within a short period since the start-stop function will otherwise automatically be launched once the brake pedal is detected to be pressed regardless of the traffic information. Therefore, it is convenient for the user to use the start-stop function, and the user would be more willing to use the start-stop function, and thus usage and operation of the start-stop function is improved.
The first transmission module 501 may be configured to transmit to a server a traffic information acquiring instruction.
