Abstract
A method of controlling a motor current for a vehicle having a motor and a steering system includes the steps of obtaining a torque signal from the steering system, calculating a torque, and adjusting the motor current based at least in part on the torque signal, the torque gain, or both.
Claims20
A method of controlling a motor current for a vehicle having a motor and a steering system, the method comprising the steps of:
- obtaining a torque signal from the steering system;
- calculating a torque gain;
- and
- adjusting the motor current based at least in part on the torque gain, the torque signal, or both.
A program product for controlling a motor current for a vehicle having a motor and a steering system, the program product comprising:
- a program configured to at least facilitate:
- obtaining a torque signal from the steering system;
- calculating a torque gain;
- and
- adjusting the motor current based at least in part on the torque signal, the torque gain, or both;
- and
- a computer-readable signal bearing media bearing the program.
A system for controlling a motor current for a vehicle having a motor and a steering system, the system comprising:
- a sensor configured to at least facilitate obtaining a torque signal from the steering system;
- and
- a processor coupled to the sensor and configured to at least facilitate:
- calculating a torque gain;
- and
- adjusting the motor current based at least in part on the torque signal, the torque gain, or both.
