The invention relates to the technical field of vehicle safety control. The invention discloses a lane keeping auxiliary system and method. The lane keeping auxiliary system comprises a detection module, a lane keeping controller and a lane keeping execution module; the detection module is used for detecting lane information and transmitting the lane information to the lane keeping controller; thecontrol input end of the lane keeping execution module is connected with the control output end of the lane keeping controller; the lane keeping execution module comprises a left front wheel proportional electromagnetic valve, a right front wheel proportional electromagnetic valve, a left front wheel brake chamber and a right front wheel brake chamber; the control input ends of the left front wheel proportional electromagnetic valve and the right front wheel proportional electromagnetic valve are respectively connected with the control output end of the lane keeping controller; the left frontwheel proportional electromagnetic valve and the right front wheel proportional electromagnetic valve are used for controlling the pressure of the left front wheel brake air chamber and the pressureof the right front wheel brake air chamber respectively, and therefore the wheel speed of the left front wheel and the wheel speed of the right front wheel are controlled respectively to generate wheel speed difference for steering to achieve lane keeping.
Description
technical field [0001] The invention belongs to the technical field of vehicle safety control, and in particular relates to a lane keeping assist system and method suitable for vehicles using pneumatic brakes. Background technique [0002] Traffic safety has increasingly become a focus of human society. In traffic accidents, the cause of many car accidents is the driver's fatigue driving or other improper operations. Commercial vehicles are a kind of production tool. In order to generate greater benefits, the driver pursues Dora and fast running, which is easy to enter the state of fatigue driving. When the driver is tired or not concentrating on driving, it is very easy to appear lane departure phenomenon And lead to traffic accidents, therefore, a reliable lane keeping technology is needed to avoid danger and improve the safety of commercial vehicle driving. In the "Technical Conditions for Motor Vehicle Operation Safety" (GB7258-2017), it is also clearly emphasized that ...
