EVC-48 < SYSTEM DESCRIPTION > SYSTEM the signal, VCM activates the system main relay 1 and deactivates the pre-charge relay. Then, normal power is supplied to the respective systems. MOTOR POWER CONTROL INFOID:0000000010120557 SYSTEM DIAGRAM NOTE: VCM calculates vehicle speed, based on a motor speed. DESCRIPTION The EV system generates traction force by converting the direct current from the Li-ion battery to an alternat- ing current by the traction motor inverter and operating the traction motor with the alternating current. VCM calculates target traction force, based on an accelerator pedal position, vehicle speed, and shift position. After this, VCM adds creep force to the calculated target traction force. Subsequently, VCM adds torque limitations to the calculated driving force, based on torque down signals received from each system, to decide a motor torque request signal. This motor torque request signal is transmitted to the traction motor inverter via EV system CAN communica- tion. For the operation principle of the motor, refer to TMS-19, "MOTOR POWER CONTROL : Operating Principle" . OUTPUT LIMIT AND OUTPUT STOP REQUEST LIST JSCIA0493GB JSCIA0778GB |
