Inflator 6, master cylinder 7, double-way check valve 10, relay valve 11, different valve 12, abs valve 13, service brake switch 14, parking system
Dynamic switch 15, rear brake chamber 16, parking braking gas chamber 17, entire car controller 20,21 operation principle of accumulator and the prior art
Inflating pump, condenser, drier, four-loop protection valve, braking gas receiver, parking gas storage afterwards in microbus air braking system
Cylinder, master cylinder, double-way check valve, relay valve, different valve, ABS valves, service brake switch, park brake switch, rear braking
Gas chamber, parking braking gas chamber, entire car controller, battery-operated principle are identical, therefore no longer repeat the present invention.
The control method of car electronics hand brake system of the present invention is as follows：
1) when pressing AUTO HOLD buttons, " AUTO HOLD " letter lights electronics parking brake switch 19 above, in instrument
It can show that AUTO HOLD functions are acting on.Master cylinder 7 is stepped on, after vehicle comes to a complete stop, entire car controller 20 receives wheel speed sensing
When the signal of device is " 0 ", even if gear be in D and keeps off, AUTOHOLD can help you by wheel locking automatically, at this time take-off the brake master cylinder
7 vehicles will not move.Step on the gas again starting when, AUTOHOLD can automatically terminate locking, and vehicle is allowed to continue to move ahead.It presses again
AUTO HOLD buttons or when stepping on master cylinder 7, AUTO HOLD functions release.
2) when stepping on master cylinder 7, when speed is " 0 ", the hand switch on electronics parking brake switch 19 is pulled down, two five
Three-way electromagnetic valve 18 is closed, even if gear is in D gears, vehicle is still in parked state.When vehicle is in " P " gear, braking is stepped on
Master cylinder 7, presses the parking brake switch above electronics parking brake switch 19, and electronic parking releases.
3) when vehicle low tension exhausts or other failures, using the mechanical button above two five-way electromagnetic valves 18,
Effect is as traditional hand control valve.
