The parking system comprises motors, pawls, ratchet wheels and a driving device, the number of the motors is two, output shafts of the two motors are each in transmission connection with a gear speed reduction mechanism, any gear speed reduction mechanism comprises a speed reduction output shaft, and the speed reduction output shaft is in transmission connection with the ratchet wheels. The axial directions of the two speed reduction output shafts are both parallel to the width direction of the automobile, and the two speed reduction output shafts are arranged in a spaced mode and collinear. The ratchet wheels are arranged on the two speed reduction output shafts respectively, the pawls are meshed with the ratchet wheels in a one-to-one correspondence mode, the middles of the pawls are rotationally arranged, and the driving device drives the ends, away from the ratchet wheels, of the two pawls to do linear motion in the fixed direction at the same time. The two pawls are driven by the driving device to ascend or descend at the same time, the two speed reduction output shafts are braked at the same time, the two ratchet wheels are arranged on the sides, close to each other, of the two speed reduction output shafts respectively, the integration degree of the dual-motor driving system is improved, the parking cost is reduced, and arrangement is convenient.

    本发明提供了一种用于分布式双电机驱动系统的驻车系统及车辆,包括电机、棘爪、棘轮以及驱动装置,电机设置有两个,两个电机的输出轴均传动连接有一个齿轮减速机构,任一齿轮减速机构均包括减速输出轴,两个减速输出轴的轴向均平行于汽车的宽度方向,且两个减速输出轴呈间隔设置并共线;棘轮在两个减速输出轴上分别设置有一个,棘爪与棘轮一一对应啮合,且棘爪的中部呈转动设置,驱动装置驱动两个棘爪远离棘轮的一端沿固定方向同时做直线运动。通过驱动装置驱动两个棘爪同时上升或下降,实现了对两个减速输出轴的同时制动,两个棘轮分别设置在两个减速输出轴相互靠近的一侧,提高了双电机驱动系统的集成度,降低驻车成本,且便于布置。
