The invention provides a control method and system for a vehicle to pass through a deceleration strip. If the deceleration strip exists in front of the vehicle, the real-time distance L1 is compared with a distance threshold value M to judge whether deceleration is needed or not, and when deceleration is needed, a deceleration strategy needing to be adopted is judged according to the current cruise vehicle speed Vc, and the vehicle is decelerated in time; after the front axle of the vehicle passes through the speed bump, comparing the real-time distance L2 with the fixed distance L to judge whether the rear axle of the vehicle passes through the speed bump, if so, taking whether the speed bump exists in the front as a precondition for acceleration recovery, and if so, continuously circulating the speed reduction judgment process until the speed bump does not exist in the front; if yes, the cruise speed Vc of the vehicle is recovered through acceleration control. The effect of decelerating the vehicle before the vehicle passes through the deceleration strip is obvious, the vehicle speed can be controlled to recover in time after the vehicle passes through the deceleration strip, and the driving experience of a driver and passengers is effectively improved.
本发明提供一种车辆通过减速带的控制方法及系统。若车辆前方存在减速带,则将实时距离L1与距离阈值M进行对比以判断是否需减速,当需减速时,则通过当前的巡航车速Vc判断所需采用的减速策略对车辆进行及时减速;当车辆前轴通过减速带后,则将实时距离L2与固定距离L进行对比以判断车辆后轴是否通过减速带,如通过,则以前方是否还存在减速带作为加速恢复的前置条件,如存在,即继续循环上述的减速判断过程,直至前方不存在减速带,则通过进行加速控制以使车辆恢复巡航车速Vc。本发明在车辆通过减速带前对车辆进行减速的效果明显,且可在通过减速带后及时控制车速恢复,有效提高了驾乘人员的驾驶体验。
