Governor circuit in the present embodiment is entire car controller, entire car controller is one of indispensable device in current automobile, for prior art, its concrete principle the present embodiment does not repeat them here, the design adopts the original intention of entire car controller to be, under the prerequisite not changing the function that original automobile has, adopt the entire car controller that automobile has itself as the governor circuit of the design, its cost of enterprise is reduced, without the need to the new circuit of bamboo product.
Realize aerobraking principle based on the automobile with uphill starting controlling functions of the present utility model as follows: suppose that automobile is kept in motion (now, electromagnetic valve not be electricly in open mode), or flat pavement running or ramp driving; If need braking, steerman steps on brake pedal, and (master brake cylinder is opened, gas in compressed air accumulator enters check valve by master brake cylinder), simultaneously, electromagnetic valve obtains and is electricly in closed condition, and master brake cylinder 4 is opened, the pressure gas in compressed air accumulator 3 by master brake cylinder 4, check valve C1, enter in right wheel braking air chamber 2 and left wheel compressed air brake cylinder 1, and then braking maneuver is carried out to the brake actuator on the wheel of both sides, automobile stops (now brake pedal does not unclamp).When not needing uphill starting, direct loosen the brake, electromagnetic valve power-off is in open mode, admission line is closed that (this is had function by master brake cylinder itself by master brake cylinder, for prior art, its concrete principle repeats no more), now in right wheel braking air chamber 2 and left wheel compressed air brake cylinder 1 gas successively by vent line 6, electromagnetic valve C2, (C1 is check valve, now gas not by) enter in master brake cylinder 4, be expelled in air in master brake cylinder 4 afterwards.Realize the releasing to car brakeing state.If now automobile is when ramp, loosen the brake, automobile will slip car phenomenon (not considering parking brake mode of operation); Whether the first pressure sensor P1 of the design is up to standard for the gaseous tension of monitoring in admission line, and as the main control signal (detecting the control energizing signal of the air pressure in admission line as governor circuit by the first pressure sensor) of electromagnetic valve action.And the second pressure sensor P2 is the feedback signal of gaseous tension, whether it is up to standard for the pressure of monitoring in vent line, when the second pressure sensor P2 has signal feedback in governor circuit, namely illustrates that vent line is smooth and easy; When the second pressure sensor P2 does not have signal feedback in governor circuit, namely illustrating that vent line exists needs maintenance extremely.And above-mentioned exception by the flicker of the Warning light (light-emitting diode can be used as Warning light) of the design or buzzer phone pipe point out steerman to note.The Warning light of the design also has prompting steerman and notes the function whether uphill starting switch is opened.
Embodiment 2, repeats no more with embodiment 1 something in common, and difference is that described governor circuit comprises micro controller system, and this micro controller system can adopt MSP430 series monolithic or 51 series monolithics in the market, or other model micro controller systems.
Embodiment 3, repeat no more with embodiment 1 something in common, difference is, method for realizing the car ramp starting as described in Example 1 with uphill starting controlling functions of the present utility model is as follows, suppose that automobile is in grade braking state, namely described master brake cylinder is in open mode; Described electromagnetic valve C2 is in closed condition, and described left wheel compressed air brake cylinder 1 and the interior punching of right wheel braking air chamber 2 have high pressure gas, and automobile is in grade braking state; The method realizing the starting of this car ramp is as follows:
(1) uphill starting switch is opened;
(2) step on brake pedal, the first pressure sensor detects the air pressure in admission line, and air pressure is fed back electric signal and input in governor circuit;
(3), after governor circuit receives the feedback electric signal of the first pressure sensor, continue Controlling solenoid valve and be in closed condition;
(4) loosen the brake, admission line is closed by master brake cylinder (gas in compressed air accumulator is braked master cylinder and completely cuts off);
(5) governor circuit Controlling solenoid valve delay N opens second, and N is greater than 2 natural numbers being less than 5;
(6) E-gas is stepped on;
(7) within N second, the opening amount signal of governor circuit Real-Time Monitoring E-gas; Within N second, if the opening amount signal that E-gas inputs in governor circuit is greater than 10%, then governor circuit Controlling solenoid valve is opened, and now, the rotating speed of driving engine via E-gas speed-raising, then can easily be started to walk; Otherwise governor circuit is opened at N Controlling solenoid valve second, slowly step on E-gas and also can start to walk.
Need described herein, E-gas is conventional device in auto trade, and has been widely used on automobile, and its concrete principle the present embodiment does not repeat them here, and described " opening amount signal " is explained as follows:
When E-gas is not stepped on, the output voltage of E-gas is 0V, opening amount signal is zero, when E-gas is stepped on completely (popular saying is when E-gas is floored), the output voltage of E-gas is 5V, now the opening amount signal of E-gas is 100%, understand for ease of illustrating, linearly to illustrate (certainly for accelerator opening amount signal and voltage signal, have different according to the difference of pedal, accelerator open degree and voltage signal might not be linear), and 10% of described opening amount signal, be the amplitude (or stroke) that E-gas is stepped on be 10% of whole amplitude (or stroke), now the output voltage of E-gas is 0.5V, be described opening amount signal 10%.
Although; what embodiment of the present utility model was announced is preferred embodiment; but be not limited thereto; those of ordinary skill in the art; very easily according to above-described embodiment, understand spirit of the present utility model, and make different amplifications and change; but only otherwise depart from spirit of the present utility model, all in protection domain of the present utility model.
