| description | To perform brake switching control, while suppressing rattling shock in decelerating a vehicle in order to stop the vehicle.SOLUTION: During transition of brake switching control by which braking torque of a wheel is gradually increased while gradually decreasing regenerative braking torque and braking torque by the regenerative braking torque is switched to braking torque by the braking torque of the wheel in decelerating a vehicle in order to stop the vehicle, the gradual decrease of the regenerative braking torque is delayed for a predetermined period of time in a predetermined vicinity of zero just before the regenerative braking torque is set to zero, and the regenerative braking torque is gradually decreased toward zero after a predetermined time elapses, so that decrease of torque for play-filling caused by an electric motor is suppressed in the predetermined vicinity of zero during the brake switching control, which can set the regenerative braking torque to zero when the play-filling is performed sufficiently. This enables the brake switching control to be performed while suppressing the rattling shock in decelerating the vehicle in order to stop the vehicle.SELECTED DRAWING: Figure 2
【課題】停車に向けた車両の減速に際して、ガタ打ちショックを抑制しつつ、制動切替え制御を行う。【解決手段】停車に向けた車両の減速に際して、回生制動トルクを漸減させつつ車輪制動トルクを漸増させて回生制動トルクによる制動トルクを車輪制動トルクによる制動トルクへ切り替える制動切替え制御の過渡中において、回生制動トルクをゼロにする前の所定のゼロ近傍で回生制動トルクの漸減が所定時間停滞させられ、所定時間経過後に回生制動トルクがゼロに向けて漸減させられるので、制動切替え制御の際、所定のゼロ近傍で電動機によるガタ詰めトルクの低下が抑制され、それによってガタ詰めが十分に行われたところで回生制動トルクがゼロとされる。よって、停車に向けた車両の減速に際して、ガタ打ちショックを抑制しつつ、制動切替え制御を行うことができる。【選択図】図２ |
