【正文】 rake 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. 。 On the other hand uses the optimized control theory, implements the servocontrol and the high accuracy control. The ABS function expansion besides ASR, simultaneously and changes the control to expand, causes ABS not merely is guards against holds the dead system, but bees the more prehensive vehicle control system. The brake development merchant also proposed future ABS/TCS and VDC and the intellectualization transportation system integration utilization conception. Along with the electronic control transmission, the system and the diverting device development, will have between the electronic control system relation work, thus will have some new functions, for example: Uses the electronic control the coupling to be possible greatly to enhance the automobile static start the efficiency。 Because road surface and vehicles state of motion change very big, the many kinds of disturbing effect is bigger, therefore the important question lies in the control the stability, namely system robustness, should maintain under each kind of condition does not lose control. Guards against holds the system request redundant reliability, otherwise can cause the person casualties and the vehicles damage. Therefore, the development robust ABS control system bees the key. Now, the many kinds of Lu stick control system applies ABS in the control logic. Besides the traditional logical threshold method is take pares as the goal, the gain dispatches the PID control, changes the structure control and the fuzzy control is the monly used Lu stick control system, is take slipping rate which at present uses as goal stepless control system. Fuzzily controls the facture is based on the thumb rule control, has nothing to do with with the system model, has very good robust and the control rule flexibility, but adjustment controlled variable quite difficult, does not have the theory to say, basically the method which is depends on tries to collect. However speaking of the majority based on the target value control, the control rule has the certain rule. Moreover, also has uses other control methods, like based on condition spatial gate and linear feedback theory method, fuzzy nerve work control system and so on. Each control method certainly is not alone applies on the automobile, usually is several control methods bines the implementation. If may blur controls and PID unifies, proper attention to both fuzzy control robustness and the PID control high accuracy, can achieve the very good control effect. The observation and control integration brake control system (abbreviation is SBC), is fills the creativity the electron to control the service pattern braking system, will install it in the future while with the vehicle on, will bee enhances an automobile driving secure new milestone. SBC uses the electronic pulse, applies the brake the order the pilot to transmit to a microprocessor in, by its synchronous processing each kind of different sensor signal, and calculates each wheel according to the specific travel condition to be most superior. Thus, when applies the brake when the corner or the wet slippery road surface, SBC can provide pared to a tradition braking system better is initiative security. The SBC system highpressured stored energy and the electrically controlled valve mechanism can guarantee most greatly the brake pressure quickly has the function. Moreover, this system provides the attachment function can reduce the pilot to drive the operation intensity. If traffic congestion auxiliary function: In under the transportation condition which stops from time to time, the automobile may operates the accelerator pedal when the pilot pine selfbraking. It gently
