Abstract: A target vehicle speed is switched between a target slip vehicle speed and a target torque vehicle speed on the basis of a result of a determination regarding whether or not a vehicle is insufficiently accelerated. More specifically, if traction control is not performed, the target slip vehicle speed is set as the target vehicle speed. If it is determined that the vehicle is sufficiently accelerated during traction control, a value obtained by subtracting a maximum permissible value from a value set last time as the target vehicle speed is compared with the target slip vehicle speed, and the larger one of them is set as the target vehicle speed this time. If it is determined that the vehicle is insufficiently accelerated during traction control, the larger one of the target slip vehicle speed and the target torque vehicle speed is compared with a value obtained by adding a maximum permissible value to a value set last time as the target vehicle speed, and the smaller one of them is set as the target vehicle speed this time.

Abstract translation: 基于关于车辆是否不充分加速的判定结果，目标车速在目标滑行车速与目标转矩车速之间切换。 更具体地，如果不执行牵引力控制，则将目标滑移车速设定为目标车速。 如果在牵引力控制期间确定车辆被充分加速，则通过从最近一次设定的值作为目标车速减去最大允许值而获得的值与目标滑行车速进行比较，并且其中较大的一个是 这次设定为目标车速。 如果确定车辆在牵引力控制期间的加速度不足，则将目标滑行车速和目标转矩车速中的较大者与通过将最大允许值相加到上次设定的值作为目标而获得的值 车速，其中较小的一次被设定为目标车速。

Abstract: A hydraulic brake apparatus for a vehicle comprises a master cylinder and an auxiliary hydraulic pressure source. A master cylinder hydraulic pressure outputted from the master cylinder is adjusted by adding a master cylinder hydraulic pressure in response to an operation of a brake operating member to a master cylinder hydraulic pressure at an auto-braking control when the brake operating member is operated during the auto-braking control. The master cylinder hydraulic pressure is adjusted by controlling an operation of a valve means so as to increase a power hydraulic-pressure supplied from the auxiliary hydraulic pressure source to a regulating means corresponding to the amount of the operation of the brake operating member.
