Control system and control method for actively avoiding side collision of automobile

Abstract

The invention relates to a control system and a control method for actively avoiding side collision of an automobile. The control system comprises a side collision avoidance control unit, and an engine management system, an electronic stable control system, a radar system, a steering wheel rotation angle sensor, a wheel velocity sensor, a transverse swinging angular velocity sensor, a safety belt detection unit, a safety belt pre-tightening control unit, a side air curtain control unit and a safety air bag control unit which are connected with the side collision avoidance control unit. The time for a vehicle on a transverse lane to pass through a crossroad is calculated by the side collision avoidance control unit according to data provided by the radar system; the time for the vehicle to pass through the crossroad is calculated according to data provided by each sensor; analysis and judgment are made; a corresponding instruction is transmitted to an executing mechanism according to a preset program; deceleration and acceleration control is performed on the vehicle; and thus, the collision of the vehicle and a vehicle on the transverse lane is avoided to the greatest extent and the damage caused by the collision is reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of safe driving of automobiles, in particular to a control system and a control method for actively avoiding side collisions of automobiles so that automobiles can avoid collisions at crossroads as much as possible and minimize possible damage caused by collisions. Background technique [0003] With the continuous development and progress of high-tech technologies such as network technology, radar detection technology, communication technology, and electronic control technology, the level of automotive electronics intelligence has developed rapidly in recent years, especially in terms of automotive active safety. The introduction of advanced technologies, such as: lane departure warning technology, lane keeping technology, driver fatigue detection system, collision prevention system, run-flat tire control system and so on. However, the current application of these active safety technologies mainly c...

Problems solved by technology

[0004] The present invention mainly solves the problem that the original automobile anti-collision system only pays attention to the possible collision between the vehicle and the front and rear vehicles, and cannot avoid and alleviate the collisions between the vehicle and the vehicle on the transverse lane at the intersection, and the anti-collision warning Most of the systems avoid accidents by braking, and the methods adopted are
