【正文】 ically, thus causes the stopping distance to reduce 5%. One kind pletely does not have the fat liquor, the plete electric circuit applies the brake BBW (BrakeByWire) the development, causes traditional the hydromatic brake into history.The entire electric brake control system is a brandnew system, has brought the huge transformation for the brake control system, will provide the condition for the future vehicles intelligence control. Must want prehensively to promote, but also has many questions to need to solve: First actuates the energy question. Uses the entire electric circuit brake control system, need more energys, a disc brake probably needs 1kW the actuation energy. At present the vehicles 12V electrical power system could not provide the such big energy, therefore, future the vehicles dynamic system will use the highvoltage, enlarged the energy supply, was allowed satisfiedly to apply the brake the energy request, simultaneously needed to solve the security problem which the high voltage brought. Next is control system expiration processing. The entire electric brake control system faces a difficult problem is brake fade processing. Because does not have the independent initiative spare braking system, therefore needs a backup system to guarantee applies the brake the security, no matter is the ECU ponent failure, the sensor expires or brake itself, the group of lines expires, all can guarantee applies the brake basic performance. Realizes an essential technology which the entire electric brake controls is time the system expiration information exchange agreement, like TTP/C. The system once appears the breakdown, sends out the information immediately, guarantees the information transmission to conform to the laws and regulations most suitable method is a multiple channel minute time zone (TDMA), it may guarantee does not appear the information lag which cannot be forecast. The TTP/C agreement acts according to the TDMA formulation. Third is antijamming processing. The vehicles can have each kind of unwanted signal in the movement process, how eliminates the influence which these unwanted signals creates, at present has the many kinds of antijamming control system, basically divides into two kinds: Namely symmetrical expression and asymmetrical antijamming control system.In summary, the modern automobile brake control technology is facing the electron brake control direction to develop. The entire electric brake control because of its huge superiority, will substitute for the tradition by the hydraulic pressure primarily tradition brake control system. At the same time, along with other automobile electronic technologies specially is the ultra large scale integrated circuit development, the electronic ponent cost and the size unceasingly drops. Automobile brake control technology development entire automobile industry development restriction. Some huge existing and latent auto market attraction, each kind of advanced electronic technology, the biological technology, the information technology as well as each kind of intelligent technology only then unceasingly apply in the automobile brake control system. Simultaneously needs each kind international and the domestic related laws and regulations perfection, like this equips newly applies the brake the technical automobile to be able truly to apply the automobile in the volume production. The electronic technology in the braking system appearance, brought for engineers has been brandnew but the prospect infinite opportunity, it was not only restricted in improves the automobile the security and fortableness. Because the automobile brake control technology, enable them to go forward in the realization longrange objective a stride. With the aid of to the camera, the shortrange radar and the advanced remote navigation system, might cause the future the automobile along the path automatic travel.
