Abstract
Systems and methods to control the vehicle speed of a vehicle includes a motor and a controller coupled to the motor. The controller is structured to: determine that a speed of a vehicle is at or above a predetermined speed limit; activate a motor speed governor responsive to an input received by the controller, wherein the motor speed governor is structured to control a vehicle speed; and adjust an output torque based on the vehicle speed being at or above the predetermined speed limit.
Claims20
A system, comprising:
- a motor;
- and
- a controller coupled to the motor, the controller structured to:
- determine that a speed of a vehicle is at or above a predetermined speed limit;
- activate a motor speed governor responsive to an input received by the controller, wherein the motor speed governor is structured to control a vehicle speed;
- and
- adjust an output torque based on the vehicle speed being at or above the predetermined speed limit.
4 more elements
A system comprising:
- at least one processing circuit comprising a processor coupled to a memory device storing instructions therein that, when executed by the processor, cause the processing circuit to:
- receive a speed of a vehicle that is at or above a predetermined speed limit;
- receive an input;
- activate a motor speed governor based on the input, wherein the motor speed governor is structured to control a vehicle speed;
- and
- adjust, via the motor speed governor, an output torque based on the vehicle speed being at or above the predetermined speed limit.
3 more elements
A method comprising:
- determining, by a controller, that a vehicle speed of a vehicle is at or above a predetermined speed limit;
- activating, by the controller, a motor speed governor responsive to an input received by the controller, wherein the motor speed governor is structured to control the vehicle speed;
- and
- adjusting, by the controller via the motor speed governor, an output torque based on the vehicle speed being at or above the predetermined speed limit.
