1. Technical Field
One or more embodiments of the present application relate to a system and method for adjusting the resolution of an information display within a vehicle.
2. Background Art
Vehicles, whether passenger or commercial, include a number of gauges, indicators, and various other displays to provide the vehicle operator with information regarding the vehicle and its surroundings. With the advent of new technologies, such as hybrid electric vehicles (HEVs), has come a variety of new gauges and information displays that help operators to better learn the operation of these vehicles that utilize new technology. For example, many HEVs incorporate gauges that attempt to provide the operator with information on the various hybrid driving states. These gauges indicate to the operator when the vehicle is being propelled by the engine alone, the motor alone, or a combination of the two. Similarly, a display may indicate when the motor is operating as a generator, and is recharging an energy storage device, such as a battery.
With regard to HEVs, it is known that sophisticated operators knowledgeable about the operation of the vehicle may require that a high level of detail be displayed to them upon an information display. By displaying a greater level of detail, an experienced operator may be capable of using the data displayed in order to optimize the performance of the vehicle. Conversely, operators who are not as sophisticated as to the operation of HEVs, or the data presented on the information display, may prefer that only a low, or minimal, level of detail be displayed. By displaying a more minimalistic level of detail, the non-sophisticated driver may be presented only with enough detail as required to operate the vehicle. Therefore, a need exists for an information display for a vehicle that allows for adjustment as to the overall level of data resolution displayed to the operator.

The generator 14 can also output torque to a shaft 26 connected to the sun gear 24. Similarly, the engine 12 outputs torque to a crankshaft 28, which is connected to a shaft 30 through a passive clutch 32. The clutch 32 provides protection against over-torque conditions. The shaft 30 is connected to the carrier 20 of the planetary gear arrangement 16, and the ring gear 18 is connected to a shaft 34, which is connected to a first set of vehicle drive wheels, or primary drive wheels 36, through a gear set 38.
The vehicle 10 includes a second electric machine, or motor 40, which can be used to output torque to a shaft 42 connected to the gear set 38. Other vehicles within the scope of the one or more embodiments of the present application may have different electric machine arrangements, such as more or fewer than two electric machines. In the embodiment shown in
The battery 48 is a high voltage battery that is capable of outputting electrical power to operate the motor 40 and the generator 14. The BCM 50 acts as a controller for the battery 48. Other types of energy storage systems can be used with a vehicle, such as the vehicle 10. For example, a device such as a capacitor can be used, which, like a high voltage battery, is capable of both storing and outputting electrical energy. Alternatively, a device such as a fuel cell may be used in conjunction with a battery and/or capacitor to provide electrical power for the vehicle 10.
As shown in
A controller area network (CAN) 56 allows the controller to communicate with the transmission 52 and the BCM 50. Just as the battery 48 includes a BCM 50, other devices may have their own controllers. For example, an engine control unit (ECU) may communicate with the controller 54 and may perform control functions on the engine 12. In addition, the transmission 52 may include a transmission control module (TCM), configured to coordinate control of specific components within the transmission 52, such as the generator 14 and/or the motor 40. Some or all of these various controllers can make up a control system in accordance with the present application. Although illustrated and described in the context of the vehicle 10, which is an HEV, it is understood that embodiments of the present application may be implemented on other types of vehicles, such as those powered by an engine or electronic motor alone.

The air conditioning system 62 also communicates with the controller 54. The on/off status of the air conditioning system can be communicated to the controller 54, and can be based on, for example, the status of an operator actuated switch, or the automatic control of the air conditioning system 62 based on related functions such as window defrost. In addition to the foregoing, the vehicle 10 may include an information display system 64 that is used to display one or more vehicle operating conditions. The information display system 64 may, as explained in more detail below, allow for adjustment as to the resolution setting of the vehicle operating conditions.
a-2c refer generally to the information display system 64 according to one or more embodiments of the present application. The information display system 64 may include an information display 66 and electronics including software which are not shown in
The information display system 64 may also include a control mechanism 68 that provides an operator the ability to adjust the resolution setting of the information display 66. The control mechanism 68 may allow the resolution setting of the information display to be adjusted through the use of a knob (as shown in
It is generally contemplated that the control mechanism 68 may be a voice recognition system (not shown) that allows audible adjustment of the resolution setting. For example, one or more embodiments of the present application contemplate that the voice recognition system may be the Ford Sync™ system currently implemented on many Ford Motor Company™ vehicles. As such, the voice recognition system may include a series of audible commands that provides the operator the capability of adjusting the resolution setting displayed on the information display 66.
The information display system 64 may further include memory (not shown), such as electrically erasable and programmable read-only memory (EPROM), which may be used to store a plurality of default resolution settings. The controller 54 may be further configured to recall from the memory the default resolution settings. Thereafter, the controller may transmit the default resolution settings to the information display 66 so that the vehicle operating conditions are displayed on the information display 66 using the default operating settings.
Alternatively, the memory may be used by an operator to store adjusted resolution settings using one or more operator parameters. The operator may use the control mechanism 68 to adjust the resolution setting of the vehicle operating conditions and to indicate to the controller 54 that the adjusted resolution setting should be stored on the memory as one of the operator parameters. Subsequently, the operator may use the control mechanism 68 to select the operator parameter stored on the memory and the controller 54 may recall the operator parameter from the memory. Once recalled, the controller 54 may transmit the operator parameter to the information display 66 so that the vehicle operating condition is displayed on the information display 66 using the operator parameter.
For example, the information display system 64 may initially be configured so that the information display 66 illustrated in
Although the information display 66 depicted in
One or more embodiments of the present application further contemplates that the information display system 64 may be configured so that the resolution setting may be adjusted automatically using a vehicle operating parameter (e.g., vehicle speed or fuel). The controller 54 may receive information indicative of an adjustment threshold and may determine whether the vehicle operating condition has exceeded the adjustment threshold. If the controller 54 determines that the vehicle operating parameter has exceeded the adjustment threshold, then the controller may determine an adjusted resolution setting. The controller 54 may then transmit the adjusted resolution setting so that the information display 66 displays the vehicle operating condition suing the automatically determined adjusted resolution setting.
For example, the information display system 64 may be configured so that the information display 66, as illustrated in
The information display system 64 may further be configured to allow replacing the default resolution setting with one of the stored operator parameters. As such, each time the vehicle 10 is operated, the controller 54 will recall from the memory the operator parameter in place of the default resolution setting. Once recalled, the controller 54 may transmit the operator parameter to the information display 66 so that the vehicle operating conditions are displayed on the information display 66 using the operator parameter.
In addition to the foregoing, the information display system 66 may be further configured so that the controller 54 may store on the memory multiple adjusted resolution settings indicative of multiple vehicle operating conditions as one of the operator parameters. For example, if the resolution settings of an engine coolant temperature gauge, speedometer, and fuel efficiency gauges were modified, the operator may use the control mechanism 68 to indicate to the controller 54 that such changes should be stored on the memory as one of the operator parameters. Thereafter, the operator may be able to use the control mechanism 68 to indicate to the controller 54 that the operator parameter should be recalled from the memory. The controller 54 may recall the operator parameter from the memory and may transmit the operator parameter to the information display 66 so that the plurality of vehicle operating conditions are displayed on the information display 66 using the operator parameter.
With reference back to
For example, the resolution setting may be adjusted so that the information display 66 displays one or more tick marks 70 indicative of the speed of the vehicle 10. As is illustrated in
Alternatively, if the resolution of the information display 66 is adjusted to a low level of detail, minor fluctuations in the vehicle operating conditions may not be displayed to the operator of the vehicle 10. As such, the low resolution setting may display the vehicle operating parameters on the information display 66 as a numerical value 72, as is shown in
Contrastingly, the resolution setting of the information display 66 may be adjusted so that the vehicle operating condition may be displayed using a moderate level of detail, as shown in
For example, an operator knowledgeable about the operation of the vehicle 10 may require a greater amount of detail regarding an amount of battery charge available. In order to display the desired level of detail, the information display 66 may be adjusted to a more detailed resolution setting. By adjusting the information display 64, the operator may be more visually informed when the battery is within a useable range or when the battery is being charged or discharged. In turn, the operator may be able to modify the operation of the vehicle 10 so that the battery is operated within the useable range. By modifying the operation of the vehicle 10 so that the battery is operated within the useable range, the operator may increase the overall efficiency of the vehicle 10.
The resolution setting of the information display 66 may also be adjusted so that the vehicle operating condition may be displayed using a high level of detail, as shown by way of example in
The information display 66 may be adjusted to the high resolution setting so that minor fluctuations in regards to the corresponding vehicle operating conditions are visible. The operator may desire minor fluctuations displayed in regards to the vehicle operating conditions, for example, during diagnostic applications or during servicing of the vehicle 10. For example, if the engine coolant temperature continually exceeded a normal engine coolant temperature threshold, a technician may increase the data resolution of the display in order to diagnose the cause. By examining the more minute fluctuations, the technician may be capable of assessing why the engine coolant temperature is exceeding the normal vehicle temperature threshold.
Alternatively, one or more embodiments of the present application contemplate that the high level of detail may be desired in order to further increase the resolution setting of a particular vehicle operating parameter. For example,
Although
With reference back to the drawings,
In step 130, the controller 54 may determine if the operator has adjusted the resolution setting to be displayed on the information display 66. If so, the controller 54 may determine that the adjusted resolution setting should be displayed on the information display 66 and the flow diagram 100 may proceed to step 160. However, if the operator has not adjusted the resolution setting to be displayed on the information display 66, then the flow diagram 100 may proceed to step 140.
In step 140, the controller 54 may determine whether to display the operator resolution settings. If the information control system 64 has been programmed to use one of the operator resolution settings, then the controller 54 gathers the operator resolution setting desired and the flow diagram 100 proceeds to step 160. Alternatively, if the information control system 64 has not been instructed to use one of the operator information display settings, then the flow diagram proceeds to step 150. In step 150, the controller 54 determines which default resolution setting should be used and the flow diagram 100 proceeds to step 160.
In step 160, the controller 54 may transmit the resolution setting selected so that the information display 66 displays the vehicle operating condition based upon the resolution setting received. The information display 66 may then be updated accordingly at step 170. For example, if one of the operator resolution settings has been selected, then the controller 54 will transmit the corresponding resolution settings and the information display 66 will display the vehicle operating conditions using the selected operator resolution setting.
