TORQUE RESPONSE CONTROL APPARATUS FOR ELECTRIC MOTOR OF VEHICLE

When a vehicle speed VSP is low, a torque response determining coefficient K is made small to lower a motor torque response, and as the vehicle speed VSP increases, the torque response determining coefficient K is increased to increase the motor torque response. With this, a delicate driving manipulation for a delicate driving power control required in a lower speed running is easily achieved, and a torque increase is rapidly made in a higher speed running, so that a sense of acceleration required in such higher speed running is fulfilled. In a lower load condition where an accelerator position APO is low, the torque response determining coefficient K is made small to lower the motor torque response, and as the load increases, the torque response determining coefficient K is increased to increase the motor torque response. With this, a delicate driving manipulation for a delicate driving power control required in a lower load running is easily achieved, and a torque increase is rapidly made in a higher load running, so that a sense of acceleration required in such higher load running is fulfilled.
