Regional adjustment for driver assistance functions
A vehicle control system and method for operating a host vehicle based on geographic location. The system includes a distance sensor, a location sensor, a user interface, and a controller including an electronic processor and a memory. The controller is communicatively coupled to the distance sensor, the location sensor, the speed control, and the user interface, and is configured to receive a distance signal from the distance sensor indicative of a distance between the host vehicle and another vehicle. The controller receives a location signal from the location sensor indicative of a location of the host vehicle and a control signal from the user interface indicative of a desired mode of operation of the vehicle control system. The controller performs a driver assistance function associated with the desired mode of operation and adjusts a tolerance of the driver assistance function based on the location of the host vehicle.
1. An adaptive control system for a host vehicle, the system comprising:
a distance sensor;
a location sensor;
a user interface; and
a controller including an electronic processor and a memory, the controller communicatively coupled to the distance sensor, the location sensor, and the user interface, the controller configured to
receive a control signal from the user interface indicative of a desired mode of operation of the vehicle control system, the desired mode of operation of the vehicle control system including an adaptive cruise control mode, a blind spot monitoring mode, and both the adaptive cruise control mode and the blind spot monitoring mode;
receive a distance signal from the distance sensor indicative of a distance between the host vehicle and another vehicle;
receive a location signal from the location sensor indicative of a location of the host vehicle, wherein the location is at least one selected from the group consisting of a rural area, an urban area, and neither a rural area nor an urban area;
generate an operating tolerance for a driver assistance function that is greater than, less than, or equal to a normative operating tolerance based on the location of the host vehicle, wherein the operating tolerance is a following distance or a distance threshold for the distance between the host vehicle and the another vehicle when the another vehicle is in a blind spot of the host vehicle; and
perform the driver assistance function associated with the desired mode of operation, the driver assistance function incorporating the operating tolerance.
2. The adaptive control system of claim 1 , wherein the controller is further configured to reference a database included within the memory to generate the operating tolerance based on the location of the host vehicle.
3. The adaptive control system of claim 1 , wherein the location sensor is a global positioning system (GPS) sensor, and wherein the controller is configured to
determine the location of the host vehicle based on the GPS sensor to obtain a geographic location of the host vehicle, and
determine the operating tolerance of the driver assistance function based on the geographic location of the host vehicle.
4. The adaptive control system of claim 1 , wherein the user interface includes a button to select the desired mode of operation of the adaptive control system.
5. The adaptive control system of claim 1 , wherein the controller is further configured to
perform the driver assistance function by setting and maintaining the following distance between the host vehicle and the another vehicle when the another vehicle is located in front of the host vehicle.
6. The adaptive control system of claim 5 , wherein the controller is further configured to
generate the operating tolerance of the driver assistance function by selecting a following distance that is less than the normative operating tolerance when the location of the host vehicle is the urban area.
7. The adaptive control system of claim 6 , wherein the controller is further configured to
generate the operating tolerance of the driver assistance function by selecting a following distance that is greater than the normative operating tolerance when the location of the host vehicle is the rural area.
8. The adaptive control system of claim 1 , wherein the controller is further configured to
perform the driver assistance function by generating a notification for a driver of the host vehicle when the another vehicle is located closer to the host vehicle than the distance threshold.
9. A method of controlling a host vehicle, the method comprising:
receiving, at a controller, a control signal indicative of a desired mode of operation of the vehicle control system, the desired mode of operation of the vehicle control system including an adaptive cruise control mode, a blind spot monitoring mode, and both the adaptive cruise control mode and the blind spot monitoring mode;
receiving, at the controller, a distance signal from a distance sensor, the distance signal indicative of a distance between the host vehicle and another vehicle;
receiving, at the controller, a location signal indicative of a location of the host vehicle, wherein the location is at least one selected from the group consisting of a rural area, an urban area, and neither a rural area nor an urban area;
generating, at the controller, an operating tolerance of a driver assistance function that is greater than, less than, or equal to a normative operating tolerance based on the location of the host vehicle, wherein the operating tolerance is a following distance or a distance threshold for the distance between the host vehicle and the another vehicle when the another vehicle is in a blind spot of the host vehicle; and
performing, at the controller, the driver assistance function associated with the desired mode of operation.
10. The method of claim 9 , further comprising:
referencing a database to determine the operating tolerance of the driver assistance function based on the location of the host vehicle.
11. The method of claim 9 , further comprising:
determining the location of the host vehicle based on a global positioning system (GPS) sensor to obtain a geographic location of the host vehicle, and
determining the operating tolerance of the driver assistance function based on the geographic location of the vehicle.
12. The method of claim 9 , further comprising
receiving a selection, via a user interface, of the desired mode of operation of the adaptive control system.
13. The method of claim 9 , wherein
performing the driver assistance function is performed by setting and maintaining the following distance between the host vehicle and the another vehicle when the another vehicle is located in front of the host vehicle.
14. The method of claim 13 , wherein
generating the operating tolerance of the driver assistance function is performed by selecting a following distance that is less than the normative operating tolerance when the location of the host vehicle is the urban area.
15. The method of claim 14 , wherein
generating the operating tolerance of the driver assistance function based on the location of the host vehicle is performed by selecting a following distance that is greater than the normative operating tolerance when the location of the host vehicle is the rural area.
16. The method of claim 9 , wherein
performing the driver assistance function is performed by generating a notification for a driver of the host vehicle when the another vehicle is located closer to the host vehicle than the distance threshold.
