PURPOSE:To prevent degradation of brake feeling, when a brake pedal is operated, by maintaining the maximum regenerative brake torque set at the time point when the brake pedal is initially operated untill the accelerator pedal is operated again. CONSTITUTION:When a brake pedal 14 is stepped in, a brake switch 20 functions and a braking operation signal is fed to a brake control circuit 30, which then sets a maximum regenerative brake torque T*MAX corresponding to a rotation signal n*. Then the maximum brake torque T*MAX is multiplied by a regenerative torque command variable signal deltaB* to produce a regenerative brake torque T*. The maximum regenerative brake torque T*MAX at this time is held as an initial value. Regenerative brake torque is obtained based on the maximum regenerative torque T*MAX which is held untill the accelerator pedal is operated. |
