Abstract

The invention discloses an intelligent automobile composite line control braking system and a braking control method thereof. The braking system combines a mechanical electric control braking system with an integrated motor type electric control braking system and is independently controlled by an electronic control unit. An electromechanical braking (EMB) module consists of two brakes. An integrated motor type electric control braking IBS module consists of an integrated motor, a ball screw mechanism and a braking pressure generation unit. The ball screw mechanism is fixedly connected to theinterior of a rotor of the integrated motor, and the rotor transmits power to an output push rod of the braking pressure generation unit through the ball screw mechanism. Two inner cavities of a maincylinder of the braking pressure generation unit generate braking pressure under the push of the output push rod, and braking control over two braking wheel cylinders is achieved through electromagnetic valves. The mechanical electric control braking system is combined with the integrated motor type electric control braking system, the problems of a single braking system are solved to achieve rapid pressure generation and precise pressure control, and braking under multiple conditions can be achieved.
