Problems solved by technology

[0004] But because existing anti-collision system mainly avoids active collision by controlling the hydraulic braking system, this kind of collision avoidance can only reduce the damage of frontal collision, can not actively avoid for side collision, and the safety of driver's driving cannot be improved. good guarantee

Abstract

The invention discloses an active collision avoidance system and a controlling method of the active collision avoidance system, and belongs to the technical field of automotive engineering and active safety. The active collision avoidance system comprises at least three radar sensors, an automotive speed sensor, a steering wheel torque angle collecting subsystem, a digital signal processing controller, a drive-by-line braking subsystem, a drive-by-line steering subsystem and an alarm display subsystem. The DSP controller is used for analyzing and processing received information, driving directions of an automobile body, the distance between the automobile body and a surrounding object and a speed difference are obtained, whether the distance between the automobile body and the surrounding object and the speed difference are in fit with safety standards or not is judged according to the driving direction of the automobile body, and if not, the DSP controller drives the alarm display subsystem to give an acoustic alarm and give an image display alarm through a CAN and controls the drive-by-line braking subsystem or the drive-by-line steering subsystem through the CAN, so that collision between the automobile body and the surrounding object is prevented.

Description

technical field [0001] The invention relates to the field of automobile technology and active safety technology, in particular to an active collision avoidance system and a control method thereof. Background technique [0002] With the progress of society, the development of economy, and the continuous improvement of people's quality of life, more and more people have cars, and the density of cars on the road is getting higher and higher. Therefore driving safety is more and more important. According to the statistics of the traffic management department, more than 80% of traffic accidents are caused by drivers who do not respond in time, and more than 65% of traffic accidents are due to rear-end collisions. In order to improve the driver's driving safety, the research on automobile collision avoidance system has very important practical significance and application prospect. [0003] At present, the automobile anti-collision system can adopt a variety of technical means, ...
