The mouth of said central process unit also is connected with disconnector and synchronous motor in turn.

A kind of control method of intelligent full automaticity brake system is characterized in that may further comprise the steps:

1) fire an engine; The camera and the apomecometer that are in the monitored control system on the travel direction are started working; With the gained data transfer in central process unit; Treater stay memory and reaction and with data by the treater analysis and count distance and arrive time of its obstacle, and the read-out from distance and fault thing recognition system reflects, forewarn system sends early warning signal simultaneously;

When to overtake automobile monitoring road surface in the place ahead 50m (general automotive safety stopping distance) has high 5m in, during obstacle in the wide 3m, read-out demonstration obstacle, the interior early warning of car; Simultaneously, during reversing automobile, monitor the obstacle in the 2m, and send early warning signal;

2) central processing unit is put in order the information of collecting; Based on the speed of a motor vehicle on the instrument show and display screen on the data that reflect make that self-actuating brake/instruction gets off the brakes; In autobrake system work, move through the synchronous motor control engine idle on the throttle system;

3) when the place ahead obstacle remains in 50m (the general automotive safety stopping distance) scope of vehicle front; Early warning signal early warning simultaneously goes out the distance of 40m, 30m, 20m, 15m, 10m, 5m, 3m, 1m in the car; Demonstration judges whether that to autobrake system work more near obstacle, it is tight more to brake according to the speed of a motor vehicle on the mileage meter; And in apart from obstacle 1-3m complete braking vehicle, this moment, electrical motor quit work.

When automobile speed at 20-40km/h, apart from the obstacle 10m of the place ahead the time, autobrake system is started working; When automobile speed at 40-60km/h, apart from the obstacle 15m of the place ahead the time, autobrake system is started working; When automobile speed at 60-80km/h, apart from the obstacle 20m of the place ahead the time, autobrake system is started working; When automobile speed at 80-100km/h, apart from the obstacle 30m of the place ahead the time, autobrake system is started working; When automobile speed at 100-150km/h, apart from the obstacle 40m of the place ahead the time, autobrake system is started working; When automobile speed at 150-200km/h, apart from the obstacle 50m of the place ahead the time, autobrake system is started working;

Simultaneously, when the reversing speed of a motor vehicle beyond 5km/h, apart from the rear obstacle 2m time, send early warning signal, autobrake system is started working, and in apart from rear obstacle 1m braking vehicle fully;

Otherwise, when automobile under equal vehicle speed condition, when obstacle distance exceeded above-mentioned corresponding numerical value, autobrake system unclamped or is in off position.

When said autobrake system was worked, electrical motor was just being changed a job and is being made the pressurization hydraulic drg, drove brake; When autobrake system unclamps, electrical motor counter-rotating work decompression hydraulic brake, loosening brake.

The present invention can make the vehicle in going keep the operating range of safety, and can in time remind chaufeur, can react rapidly in the face of emergency situation, guarantees safe distance between vehicles, the generation of minimizing accident.
