Patent Images
1. A control system for an electric drive system of a vehicle having at least one electric drive motor in communication with a driven wheel of the vehicle, the control system comprising:
- an accelerator of the vehicle capable of causing generation of an accelerator input signal;
a plurality of sensors mounted within the vehicle and each providing a sensor input signal;
a drive controller in communication with the at least one electric drive motor to facilitate adjustment thereto based on the accelerator input signal and at least one of the sensor input signals; and
an auxiliary controller in communication with at least one electric auxiliary motor and the drive controller to facilitate adjustment of the at least one electric auxiliary motor.
