Automobile intelligent brake execution system and implementation method

Abstract

The invention provides an intelligent automobile braking execution system and an implementation method, and belongs to the technical field of automobiles. The intelligent automobile braking execution system comprises an automobile braking system. An SBS execution system and an SBS control system are connected to the position behind an automobile braking master pump. The SBS execution system is formed by reversely arranging an interface and applying the interface through an existing mature and reliable ABS hydraulic system assembly. The SBS control system comprises an ABS hydraulic assembly and an electronic control unit assembly. According to the intelligent automobile braking execution system, an existing ABS is skillfully, creatively and boldly applied, the ABS characteristics widely adopted by automobile factories can be fully exerted, the effect that the automatic braking function is implemented is ensured, and the original anti-lock function and artificial braking function of an automobile cannot be influenced; and meanwhile, the new functions of auxiliary automatic braking and the like are achieved, and the using effect is creative.

Description

technical field [0001] An automobile intelligent braking execution system and an implementation method belong to the technical field of automobiles. Background technique [0002] There are more and more cars in use around the world, but the existing vehicles need to rely on the driver to complete the braking function. Due to the limitation of the driver's physiological characteristics, a large number of lives and property are caused every year due to braking delays such as high-speed tire blowouts, rear-end collisions, and fatigue driving. loss. To improve driving safety, it is urgent to adopt intelligent automatic rescue technology, which is inseparable from the most important executive mechanism, that is, the automatic braking deceleration mechanism, so that it can replace the driver in the braking system after receiving various safety control instructions. The braking power is automatically generated, and under the control of the intelligent system, the automatic braking...

AI Technical Summary

Problems solved by technology

If the existing ABS has an automatic braking function, it is necessary to make necessary modifications to its hardware and control program, but since the ABS itself is connected in series between the brake master cylinder and the slave cylinder, and the slip ratio must be accurately adjusted Control in order to ensure the anti-lock braking function, and the control strategies of different models, weights and structures are different. It needs to be calibrated separately and go through a large number of road tests before it can be used with confidence. Once any newly added components and software design have any flaws , will lead to unimaginable consequences

Therefore, the existing technical scheme of adopting ABS improvement has not been able to be applied in the whole vehicle factory; some suggest to adopt the ESP system with ABS to implement the automatic braking function, but this proposal has not been widely promoted and adopted by the vehicle factory. One is because of the high configuration cost of ESP itself, the proportion of configuration in new cars produced in my country is very small, and only high-end cars have it. Monopolized by a small number of manufacturers, because it involves precise control such as slip rate, any changes to its hardware and software will lead to recalibration of this car, and the ABS system and ESP control strategy of each model are not universal, resulting in its configuration. It is very difficult to popularize it, especially when the existing EPS system control strategy solves the problem of tire blowout rescue, if the program is not revised, it will bring greater disasters. Has been afraid to be easily adopted, so a large number of new cars do not have automatic braking function
