The concrete principle of work of this automobile assistant braking system is: first, the signal of Central Processing Unit (CPU) Real-Time Monitoring car speed sensor and electronic control unit, when vehicle speed is greater than 60km/h and electronic control unit and controls anti-lock vehicle system and enter mode of operation, Central Processing Unit (CPU) judgement vehicle needs emergency brake, Central Processing Unit (CPU) is controlled the friction stopping device being arranged on vehicle chassis and is entered auxiliary braking state, controller control cylinder starts, the piston rod of cylinder drives crank to make brake connecting rod to the outer side shifting of vehicle chassis, frictional damping piece is transformed into retarder location from security bit,
Secondly, the signal of Central Processing Unit (CPU) Real-Time Monitoring chassis height sensor, and the movement range of the piston rod by controller control cylinder size, make the frictional damping piece that enters retarder location regulate its position according to the different self adaptations of vehicle speed and road conditions, make vehicle chassis in plateau;
Finally, when the speed of a motor vehicle of vehicle is zero, Central Processing Unit (CPU) judgement vehicle stops completely, and control friction stopping device stop braking, the piston rod of controller control cylinder drives crank-operated, make brake connecting rod to the medial movement of vehicle chassis, frictional damping piece is transformed into security bit from retarder location.
When vehicle speed is greater than 60km/h and brake anti-lock device and enters mode of operation, Central Processing Unit (CPU) comprehensively can be surveyed the signal of the chassis height sensor of road bump situation simultaneously, analyze the situation of chassis plateau in judgement emergency braking and Vehicle Driving Cycle process, the friction stopping device that makes to be arranged on vehicle chassis enters rapidly auxiliary braking state, stopping distance is shortened, and braking effect is brought up to optimum regime.
Beneficial effect: this auxiliary braking system relies on the piston rod of cylinder to make crank-operated, the swing of crank by hinged brake connecting rod drive frictional damping piece to the inner side of car chassis or outside side shifting, realize the conversion between security bit and retarder location, can make automobile stop in the shortest skidding distance, guarantee safety of person vehicle, can improve and under sleety weather, only have the braking of brake anti-lock device work not enough, reduce traffic accident;
Central Processing Unit (CPU) is according to the signal of chassis height sensor, the piston rod of controller control cylinder makes crank drive brake connecting rod to deviate from the amplitude size of car chassis motion, can make frictional damping piece along with the self adaptation that the difference of the speed of a motor vehicle and the difference of road conditions condition realize its position regulates;
When automobile stops completely, Central Processing Unit (CPU) is regained on car chassis the piston rod of controller control cylinder, convenient and swift, does not affect the outward appearance of automobile.
