The invention discloses a method for reducing vehicle jerk and a vehicle braking device, and belongs to the field of vehicle braking. The method for reducing vehicle jerk comprises the following steps: obtaining actual vehicle speed, actual deceleration and actual jerk degree, and determining the deceleration and jerk degree required by a driver by monitoring the demand of the driver; under the condition that the actual deceleration is constant, calculating the expected jerk of the vehicle reaching the static state; judging whether the expected jerk of the vehicle reaching the static state exceeds a jerk limit value or not, and if so, calculating an intervention time point at which the deceleration should be reduced to enable the expected jerk to be lower than the jerk limit value according to a preset deceleration curve; and when the intervention time point is reached, judging whether the jerk required by the driver is between 0 and a preset jerk, and if yes, adjusting the braking pressure of a braking unit according to a preset deceleration curve, and applying braking torque to the wheels.

    本发明公开的是一种降低车辆急动方法及车辆制动装置,属于车辆制动领域,一种降低车辆急动方法,包括如下步骤:获取实际车速、实际减速度和实际急动度,通过监控驾驶员需求,确定驾驶员所需减速度和所需急动度;在实际减速度恒定的情况下,计算汽车达到静止状态的预期急动度;判断汽车达到静止状态的预期急动度是否超过急动度极限值,若超出,则根据预设定的减速度曲线计算出应减小减速度使预期急动度低于急动度极限值的介入时间点;当到达所述介入时间点时,判断驾驶员所需急动度是否在0和预设定的急动度之间,若是,则根据预设定的减速度曲线调节制动单元的制动压力,对车轮施加制动力矩。
