Embodiment Construction

[0023] Such as figure 1 As shown, the vehicle emergency braking system 10 includes a vehicle emergency braking system 10 , a decision-making control unit 11 , an image acquisition unit 12 , a radar acquisition unit 13 , a human-computer interaction unit 14 , a power supply unit 15 and an execution unit 20 . The image acquisition unit 12 is used to acquire the video or image information in front of the own vehicle and process it to obtain the information of the vehicles and personnel in front of the own vehicle in the lane. The radar acquisition unit 13 is used to detect the distance and speed information of the obstacle in front of the vehicle. The human-computer interaction unit 14 realizes the opening and closing of the system, and displays warning information. The decision-making control unit 11 receives the information output by the image acquisition unit 12 and the radar acquisition unit 13, processes it and outputs it to the execution module, which controls the brake an...

Abstract

The invention discloses a vehicle emergency braking system. An image acquisition unit and a radar acquisition unit outputs an acquired signal for a barrier in front of a vehicle to a decision-making control unit; the decision-making control unit outputs a control signal to an execution unit; and the execution unit comprises an accelerator control sub unit and a braking control sub unit. According to the vehicle emergency braking system, vehicle and personnel detection and tracking are more accurate by fusing a visual technology and a laser radar technology, safety under various weather conditions is better guaranteed, traffic accidents are reduced, the safety is improved, and mental pressure of a driver is alleviated. The system can achieve an automatic cruise function at a high speed, braking is implemented actively under dangerous conditions, and emergency braking is adopted when a collision danger occurs; and meanwhile, vehicle automatic cruise is achieved while a collision problem is solved.

Description

technical field [0001] The invention relates to the technical field of active safety, in particular to an automatic cruise emergency braking system based on laser radar and vision. Background technique [0002] According to the survey, 90% of traffic accidents are caused by driver's inattention, and vehicles equipped with AEB system (Autonomous Emergency Braking automatic braking system) can reduce the accident rate by 27%, and can significantly reduce accident casualties , Improve vehicle driving safety. EU NCAP announced that starting from 2014, the AEB system will be included in the car safety rating bonus items. However, the current AEB system is difficult to operate reliably in response to urban low-speed, inter-city express and pedestrian protection, making it difficult to guarantee the reliability of the system. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a safe, stable and reliable system operation,...
