摘要： An electric vehicle control system for driving a battery powered motor with use of power inverters. First and second inverters are connected with the respective three-phase primary windings of an induction motor. If one of the inverters fails, failure detection circuits detect it, and a control unit stops the failed inverter and allows the other normal inverter to drive the induction motor to move the electric vehicle. Driving the single motor with a plurality of power inverters allows the electric vehicle to move and run even if one of the power inverters fails.

摘要： A counter (12) is provided to count an output pulse which a pulse generator (5) generates each time a vehicle moves by a predetermined distance. A microprocessor (2) is provided to actuate a timer (11) in synchronism with the leading edges of the output pulse from the pulse generator (5). The timer (11) is set to a constant time interval during which the speed of the vehicle is to be detected. The microprocessor (2) calculates the speed of the vehicle from the count of the counter (12) which count is a value during the time interval from when the timer (11) starts to operate to when the pulse generator (5) generates a pulse just before or after the end point of the set time interval. Thus, the speed of the vehicle can be detected with good resolution and precision.
