<p>PURPOSE:To prevent increment of deceleration immediately before stoppage, by applying reversing torque onto a motor in a region where vehicle speed is higher than a predetermined level, while applying forward torque onto the motor in region where the vehicle speed is lower than the predetermined level when stepping force of brake is small. CONSTITUTION:Vehicle speed N, accelerator stepping amount S and hydraulic brake pressure P detected through a vehicle speed sensor 20, an accelerator sensor 22 and a hydraulic brake sensor 24 are provided to a torque command operating section 18. The torque command operating section 18 operates a torque command T based on these input signals and performs switching control of a main inverter circuit 12. When brake stepping force is high, reversing torque is applied continuously as regenerative brake torque. While when brake stepping force is low, reversing torque is provided for a vehicle speed N higher than a predetermined level and forward torque is provided for vehicle speed lower than the predetermined level.</p> |
