<P>PROBLEM TO BE SOLVED: To provide a drive system for a practical electrically operated vehicle. <P>SOLUTION: The drive system includes an alternating-current (AC) motor for providing a drive torque. An AC motor controller receives a power supply voltage signal, throttle pedal position signal, brake pedal position signal, key switch signal, forward/neutral/reverse (FNR) signal, and run/tow signal indicative of the utility vehicle being configured to be driven and being configured to be towed. The AC motor controller generates an AC drive signal for the AC motor, wherein the AC drive signal is based on the power supply voltage signal, throttle pedal position signal, brake pedal position signal, key switch signal, FNR signal, and run/tow signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
