Automobile lane change collision avoidance control method

The invention discloses an automobile lane change collision avoidance control method, and belongs to the field of automobile active safety. Automobile related information and external environment related information are collected by related sensors on an automobile, the related information is input to an electronic control unit (ECU), and the ECU analyzes signals of all the sensors, determines the automobile driving emergency situation, rapidly schedules a lane change route, and establishes a longitudinal least safety distance model. According to the scheduled route and the safety distance model, the opening degree and braking force of a throttling valve are reasonably controlled; a steering motor is controlled at proper position so that the automobile can be driven along the scheduled route, and the input amount of a yaw velocity sensor is detected at any time; on the premise of ensuring stability, a steering wheel is adjusted to rotate to the motor, it is ensured that the automobile track is well tracked, and the aim of collision avoidance is achieved.
