本发明公开了一种电动式中央驻车制动器,包括:制动器前壳,其具有容纳室,制动器前壳固定连接在变速器壳体上,且制动器前壳具有通孔;两个电机,其均设置在容纳室内;两个电机输出端分别通过两个联轴器与两个蜗杆相连接,两个蜗杆分别通过两个涡轮、两个传动轴将动力传输到两个锁止齿轮,所述两个锁止齿轮一侧为齿轮结构,另一侧为平滑结构;制动器后壳,其一端穿过通孔与传动轴相连接,另一端可转动的设置在制动器前壳内部,制动器后壳具有凹槽;其中,凹槽内部具有内齿轮,且内齿轮能够与两个锁止齿轮相啮合。本发明还公开了一种电动式中央驻车制动器的控制方法,通过车辆状态参数采取不同的驻车制动策略控制驻车制动器的开关。

    The invention discloses an electric central parking brake, which comprises a brake front shell, two motors, and a brake rear shell; the brake front shell is provided with an accommodating chamber; thebrake front shell is fixedly connected with a transmission shell; the brake front shell is provided with two through holes; the two motors are arranged in the accommodating chamber; the output ends of the two motors are connected with two worms through two couplers respectively, the two worms are used for transmitting power to two locking gears through two turbines and two transmission shafts respectively, one side of each locking gear is of a gear structure, and the other side of each locking gear is of a smooth structure; one end of the brake rear shell penetrates through a through hole tobe connected with a transmission shaft, the other end of the brake rear shell is rotatably arranged in the brake front shell, and the brake rear shell is provided with a groove; an inner gear is arranged in the groove, and the inner gear can be meshed with the two locking gears. The invention further discloses a control method of the electric central parking brake. Different parking braking strategies are adopted to control the parking brake to be turned on and off according to the vehicle state parameters.
