    摘要： A pulse width modulator (PWM) circuit for generating pulses to enable a driver control unit to drive a pair of switching circuits for an electric motor including an input section for receiving an N bit digitized input signal to be modulated and a PWM counter for continuously counting up from zero to a predetermined number and back down to zero, the PWM counter generating a digitized triangular waveform having N bits of resolution corresponding to the predetermined number. A compare unit receives and compares the digitized input signal and the digitized triangular waveform to produce an output pulse and a dead-time generator unit produces a first pulse and a second pulse from the output pulse produced from the compare unit. The first and second pulses each drives a corresponding one of the switching circuits and the first and second pulses have different transition times relative to each other. A built-in test (BIT) circuit provides BIT input signals corresponding to the first and second pulses to verify correct operation of the PWM circuit including a feed back path from the driver control unit, the driver control unit having a higher level of integration than the PWM circuit, and the BIT input signals providing individual control of each of the PWM signals.

    摘要： 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.
