The invention provides a method and system for reversely decelerating an automobile, and relates to the technical field of automobile braking. The method comprises the steps that the running speed of an automobile is detected, and whether the running speed exceeds a first threshold value or not is judged; when it is detected that the running speed exceeds a first threshold value, starting to record a duration time value when the running speed exceeds the first threshold value, and judging whether the duration time value exceeds a second threshold value or not; when the duration time value exceeds a second threshold value, an obstacle detection module is controlled to monitor whether an obstacle exists within a preset distance in front of the automobile or not; when the obstacle is detected, the super capacitor discharge module is controlled to discharge; and the reverse rotation driving module receives the current of the super capacitor discharging module and drives the automobile wheels to reversely rotate. Wheels are guided to reverse rotation movement through the reverse rotation driving module, the vehicle speed is effectively reduced, and therefore the vehicle is prevented from colliding with obstacles or other dangers.

    本公开提供了一种使汽车反向减速的方法及系统,涉及汽车制动技术领域。该方法包括:检测汽车的运行速度,并判断所述运行速度是否超过第一阈值;当检测到所述运行速度超过第一阈值时,开始记录所述运行速度超过所述第一阈值的持续时间值,并判断所述持续时间值是否超过第二阈值;当所述持续时间值超过第二阈值时,控制障碍物检测模块监测汽车前方预设距离内是否存在障碍物;当检测到障碍物时,控制超级电容放电模块放电;反向逆转驱动模块接收到超级电容放电模块的电流,带动汽车车轮反向逆转。通过反向逆转驱动模块将车轮导向反向逆转运动,有效降低车速从而避免撞击障碍物或其他危险。
