Title:
MOTOR OPERATED VEHICLE
Document Type and Number:
Japanese Patent JP3463267
Kind Code:
B2
Abstract:
PURPOSE: To stop a motor even at the time of erroneously operating a CPU, etc., by altering an output torque command value to a value for stopping the motor and controlling a motor current when an output torque cut command is received.
CONSTITUTION: When a driver selects a neutral range or a parking range to instruct cut-off of an output torque, output torque cut-off instructing means (TC) 32 generates an output torque cut-off command signal (CS) (a). When the CSa is input to output torque command value calculating means (OT) 15, the OT 15 sets the output torque command value to zero or close to zero to stop a motor 25. A motor driving circuit 34, when receiving the output torque command value, stops the supply of a motor current to the motor 25. The CSa is output to a current interrupting mechanism 36 through a signal delay circuit 35 without intermediary of a CPU. Accordingly, even if the OT 15, the motor circuit 35 are erroneously operated, the motor 25 can be effectively stopped with the CSa.
