  • Electric vehicle chassis controller
    Patent number: 5508594
    Abstract: A vehicle power controller for a vehicle including a motor that drives the vehicle, a plurality of sensors and a motor controller, wherein the plurality of sensors includes an accelerator sensor for sensing a position of an accelerator pedal and a brake sensor for sensing a position of a brake pedal, and wherein the motor controller controls torque output of the motor. The vehicle power controller includes three components. The first receives signals from the accelerator sensor and the brake sensor. The second converts the signals for the accelerator sensor and the brake sensor into a torque value, and the third outputs the torque value to the motor controller for controlling the torque output of the motor.

  • Control mechanism for electric vehicle
    Patent number: 5463294
    Abstract: A motor controller for a vehicle including an electric motor that drives the vehicle, a plurality of sensors and a vehicle power controller. The vehicle power controller receives signals from an accelerator sensor and a brake sensor, converts the signals for the accelerator sensor and the brake sensor into a torque value. The motor controller comprises three components. A first component receives the torque value from the vehicle power controller. A second component converts the torque value into a torque output; and a third component controls the motor in accordance with the torque output.
