The specific embodiment
As shown in Figure 1, the utility model comprises brake system and the BMBS controller 3 of tire pressure monitoring and sensing device 1, tachogen 2, band ABS/ESP.The feeder ear of brake system feeder ear and BMBS controller 3 all is connected with automotive battery.Tire pressure monitoring and sensing device 1 is arranged in each wheel of automobile, it is converted to electric parameter with the atmospheric pressure value in the tire and gives the BMBS controller 3 that is arranged on the vehicle body by transmission of wireless signals, BMBS controller 3 has the Data Management Analysis function, and it is connected with the electronic control unit 4 of the brake system of band ABS/ESP.The brake system of band ABS/ESP comprises pump motor 5, hydraulic control unit and electronic control unit 4, hydraulic control unit has comprised energy storage 7, solenoid directional control valve 8, electromagnetic isolation valve 9, normally closed valve 10, normally open valve 11 and drg 12, connects by brake piping between these parts and the energy storage 7.Solenoid directional control valve 8, electromagnetic isolation valve 9, normally closed valve 10, normally open valve 11, tachogen 2 all are connected with electronic control unit 4 by signal wire (SW).
Each tire pressure monitoring and sensing device 1 is all being monitored the tire pressure of place inside wheel separately always, and outwards launch by radiofrequency emitting module, the wireless receiving module of BMBS controller 3 receives signal and signal is handled and analyzed, when the tire pressure signal reaches the threshold value of setting, BMBS controller 3 can go out the instruction that flat tire braking system starts, and electronic control unit 4 receives instruction back startup hydraulic control unit and sets up brake-pressure.As shown in Figure 1, this moment, solenoid directional control valve 8 and normally open valve 11 were opened, and electromagnetic isolation valve 9 and normally closed valve 10 are closed, and pump motor 5 pumps into brake wheel cylinder on the drg 12 with the braking liquid in vacuum booster 6 master cylinders, and brake-pressure rise is realized braking effect.
Because the brake system of band ABS/ESP has the anti-lock function, therefore when brake-pressure rise arrives the locking limit, solenoid directional control valve 8 and normally open valve 11 are closed, electromagnetic isolation valve 9 and normally closed valve 10 are opened, as shown in Figure 2, this moment, pump motor 5 back fail master cylinder with braking liquid, and the brake-pressure reduction in the pipeline makes braking force remain under the locking threshold values.
