Electric engine accessory control
A method of controlling a vehicle accessory includes determining a transmission of a vehicle is in a non-park setting; in response to determining the transmission of the vehicle is in the non-park setting, receiving speed data indicative of a speed of the vehicle; determining a speed to operate the vehicle accessory based on the vehicle speed; comparing the determined speed to operate the vehicle accessory to a speed threshold; and in response to determining that the determined speed is below the speed threshold, providing a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state of the vehicle accessory.
1. A method, comprising:
determining a transmission of a vehicle is in a non-park setting;
in response to determining the transmission of the vehicle is in the non-park setting, receiving speed data indicative of a speed of the vehicle;
determining a speed to operate a vehicle accessory based on the vehicle speed, wherein greater vehicle speeds correspond with lower determined speeds to operate the vehicle accessory;
comparing the determined speed to operate the vehicle accessory to a speed threshold; and
in response to determining that the determined speed is below the speed threshold, providing a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state of the vehicle accessory.
2. The method of claim 1 , wherein the vehicle accessory is a power steering pump.
3. The method of claim 1 , wherein the reduced operating state corresponds with a predefined power consumption amount for the vehicle accessory.
4. The method of claim 1 , further comprising:
determining the transmission is in a park setting; and
deactivating the vehicle accessory.
5. The method of claim 4 , wherein the vehicle accessory is a power steering pump.
6. The method of claim 1 , wherein the determined speed to operate the vehicle accessory is linearly related to the vehicle speed.
7. The method of claim 1 , wherein the vehicle accessory is an electrically-driven vehicle accessory.
8. A system, comprising:
a vehicle accessory; and
a controller coupled to the vehicle accessory, the controller structured to:
determine a transmission of a vehicle is in a non-park setting;
receive speed data indicative of a speed of the vehicle;
determine a speed to operate the vehicle accessory based on the vehicle speed, wherein greater vehicle speeds correspond with lower determined speeds to operate the vehicle accessory;
compare the determined speed to operate the vehicle accessory to a speed threshold; and
in response to determining that the determined speed is below the speed threshold, provide a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state for the vehicle accessory.
9. The system of claim 8 , wherein the vehicle accessory is a power steering pump.
10. The system of claim 8 , wherein the reduced operating state corresponds with a predefined power consumption amount for the vehicle accessory.
11. The system of claim 8 , wherein the controller is further structured to:
determine the transmission is in a park setting; and
deactivate the vehicle accessory.
12. The system of claim 11 , wherein the vehicle accessory is a power steering pump.
13. The system of claim 8 , wherein the determined speed to operate the vehicle accessory is linearly related to the vehicle speed.
14. The system of claim 8 , wherein the vehicle accessory is an electrically-driven vehicle accessory.
15. A system for a vehicle, the system comprising:
a controller including at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause operations including:
determine a transmission of a vehicle is in a non-park setting;
receive speed data indicative of a speed of the vehicle;
determine a speed to operate a vehicle accessory based on the vehicle speed, wherein greater vehicle speeds correspond with lower determined speeds to operate the vehicle accessory;
compare the determined speed to operate the vehicle accessory to a speed threshold; and
in response to determining that the determined speed is below the speed threshold, provide a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state for the vehicle accessory.
16. The system of claim 15 , wherein the vehicle accessory is a power steering pump.
17. The system of claim 15 , wherein the reduced operating state corresponds with a predefined power consumption amount for the vehicle accessory.
18. The system of claim 15 , wherein the operations further include:
determine the transmission is in a park setting; and
deactivate the vehicle accessory.
19. The system of claim 18 , wherein the vehicle accessory is a power steering pump.
20. The system of claim 15 , wherein the determined speed to operate the vehicle accessory is linearly related to the vehicle speed.
