In other conditions, detailed explanations of method, circuit, device and system well known to the public are omitted, so that unnecessary details which are disadvantageous to the understanding of the description of the present disclosure may be avoided.
For the illustration of the technical solutions of embodiments of the present disclosure, the technical solutions of the present disclosure are described in detail according to embodiments below:
At a step of S101, position information of a terminal device is received from the terminal device, and position information of the vehicle is obtained.
In some embodiments, the terminal device may be a vehicle key or a mobile electronic device, and the mobile electronic device may be a mobile phone, a tablet computer, or the like in embodiments of the present disclosure.
In one embodiment, as shown in
That is, when the terminal device receives an instruction for turning on the outer lamp of the vehicle as input by a driver, the terminal device send the information for turning on the outer lamp of the vehicle to the vehicle controller. It should be noted that, when an activation switch on the terminal device is pressed by the driver, the terminal device correspondingly receives the instruction for turning on the outer lamp of the vehicle input by the driver correspondingly, which indicates that the driver wishes to activate the vehicle entry mode based on light guidance. Here, “the vehicle entry mode based on light guidance” is merely a name of a mode indicating that the user wishes to turn on the outer lamp of the vehicle currently, and the name of the mode is not limited in the present disclosure. The driver may change the name of the mode by setting according to his/her requirement, preference, and the like.
In some embodiments, after the terminal device turns on the vehicle entry mode based on light guidance, the terminal device sends the position information of the terminal device to the vehicle controller, in order that the vehicle controller turns on the outer lamp in the orientation corresponding to the position information of the terminal device.
In some embodiments, the position information of the terminal device may be global positioning system (Global Positioning System, GPS) information of the terminal device, that is, a GPS information generation module is arranged on the terminal device, so that the corresponding GPS information can be generated in real time according to the movement of the terminal device.
Similarly, a GPS information generation module may also be arranged in the vehicle, so that the vehicle controller can obtain real-time GPS information of the vehicle according to the GPS information generation module.
In a step of S102, a distance between the terminal device and the vehicle is calculated according to the position information of the terminal device and the position information of the vehicle.
In some embodiments, this step can be implemented by generating the distance between the terminal device and the vehicle (i.e., the distance between a person and the vehicle) according to the GPS information of the terminal device and the GPS information of the vehicle.
In a step of S103, when the distance is shorter than or equal to a preset distance threshold, first orientation information of the terminal device with respect to the vehicle head orientation of the vehicle is generated, and an outer lamp of the vehicle corresponding to the position of the terminal device is turned on according to the first orientation information.
In one embodiment, as shown in
In one embodiment, firstly, third orientation information of the vehicle head orientation of the vehicle may be generated according to the position information of the vehicle, the third orientation information is a second included angle between a second straight line formed by a connection line between the vehicle head and the vehicle tail of the vehicle, and a horizontal coordinate axis or a longitudinal coordinate axis in a coordinate system established by taking the vehicle as the origin. In some embodiments, as shown in
The position information of the vehicle head of the vehicle and the position information of a parking spot of the vehicle are calculated according to the third orientation information and the position information of the vehicle. In some embodiments, when the position information of the vehicle head and the position information of the parking spot of the vehicle are calculated, this calculation may be performed according to the vehicle length of the general vehicle. For example, the vehicle length may be 5 meters, and the position information of the vehicle is the information of the center position of the vehicle, that is, the information of the position at the 2.5 meters length of the vehicle. Thus, the position information of the vehicle head and the vehicle tail may be calculated according to a deflection angle of the vehicle head.
A first distance between the terminal device and the vehicle head is calculated according to the position information of the terminal device and the position information of the vehicle head of the vehicle;
A second distance between the terminal device and the vehicle tail is calculated according to the position information of the terminal device and the position information of the parking spot of the vehicle. The first distance and the second distance are used as the first information.
In some embodiments, after the first distance and the second distance are calculated, when the first distance is shorter than the second distance, that is, the terminal device is closer to the vehicle head, the outer lamps corresponding to the vehicle head (i.e., the front-left-outer-lamp of the vehicle and the front-right-outer-lamp of the vehicle) is turned on.
When the first distance is greater than the second distance, that is, the terminal device is closer to the vehicle tail, the outer lamps corresponding to the vehicle tail (the rear left outer lamp and the rear right outer lamp of the vehicle) is turned on.
In order to further save the power consumption of the lamps of the vehicle, the lamp control of the vehicle may be performed in the following manner.
In one embodiment, as shown in
As shown in
As shown in
a difference value between the first included angle and the second included angle is calculated according to the second orientation information and the third orientation information, and the difference value is taken as the first orientation information.
In order to determine the outer lamp which should be turned on subsequently, it is necessary to confirm the orientation information of the terminal device with respect to the vehicle head. Thus, the relative angle between the first straight line and the second straight line needs to be calculated according to the determined second orientation information and the third orientation information, that is, the relative angle between the first straight line and the second straight line can be obtained by subtracting the second included angle from the first included angle. As shown in
As shown in
In some embodiments, when the terminal device is in the direction perpendicular to the direction of the vehicle body of the vertical, that is, when the terminal device is just located at a positive left direction or a positive right direction with respect to the vehicle head of the vehicle, the outer lamps close to the vehicle head (i.e., the front-left-outer-lamp and the front-right-outer-lamp) may be turned on, so that the driver can open a vehicle door directly and conveniently and enter the vehicle.
In one embodiment, as shown in
According to embodiments of the method for the lamp control of the vehicle, the position information of the terminal device sent by the terminal device is received, the position information of the vehicle is obtained, and the distance between the terminal device and the vehicle is calculated according to the position information of the terminal device and the position information of the vehicle. When the distance is shorter than or equal to the preset distance threshold, the first information of the terminal device with respect to the vehicle is generated, and the outer lamp corresponding to the location of the terminal device is turned on according to the first information. In this way, the outer lamp of the vehicle corresponding to the location of the terminal device can be turned on when the terminal device is located within coverage distance of the outer lamp, intelligent illumination for road condition is provided to the driver in the vehicle entering process of the driver, a problem of inconvenience of the driver for walking to the location of the vehicle under relatively dark light is avoided, and an occurrence of personal safety problem is even avoided.
