The invention discloses a hydraulic braking device which comprises a liquid pot, a motor main cylinder adjusting valve, a motor main cylinder, a motor main cylinder isolating valve and a wheel cylinder. Wherein the liquid pot is used for storing brake liquid; the motor main cylinder regulating valve is connected between the liquid pot and the motor main cylinder, and the motor main cylinder isolating valve is connected between the motor main cylinder and the wheel cylinder; after the ABS anti-lock function is triggered, the motor main cylinder isolating valve is closed firstly, the motor main cylinder adjusting valve is opened, the motor main cylinder sucks brake fluid from the fluid pot, then the motor main cylinder adjusting valve is closed firstly, the motor main cylinder isolating valve is opened, the motor main cylinder supplements the brake fluid sucked from the fluid pot into the wheel cylinder, and the brake fluid is rapidly supplemented into the wheel cylinder. Therefore, sufficient brake fluid in the wheel cylinder can be ensured, sufficient brake force at the wheel end is ensured, and a better brake effect is achieved. The invention further provides a control method of the zero dragging torque, the fuel economy and the endurance mileage of the automobile can be improved, and the control method is particularly suitable for the new energy automobile.
本发明公开了一种液压制动装置,包括:液壶、电机主缸调节阀、电机主缸、电机主缸隔离阀和轮缸;其中,液壶用于储存制动液;电机主缸调节阀连接于液壶和电机主缸之间,电机主缸隔离阀连接于电机主缸和轮缸之间;当ABS防抱死功能触发后,电机主缸隔离阀先关闭,电机主缸调节阀打开,电机主缸从液壶中吸入制动液,随后,电机主缸调节阀先关闭,电机主缸隔离阀打开,电机主缸将从液壶中吸入的制动液补入轮缸中,实现向轮缸快速补入制动液,从而能够确保轮缸内仍有足够的制动液,保证轮端制动力充足,达到较好的制动效果。本发明还提出了一种零拖滞力矩的控制方法,可提升汽车燃油经济性及续航里程,尤其适用于新能源汽车。
