An embodiment who is illustrated in figure 1 the utility model integrated form automatic parking brake device, comprises the ECU (Electrical Control Unit) ECU with car status information input port 90, and braking during standstill unit 1, rear service brake unit 2 and front driving brake unit 3 are embodied as:
Braking during standstill unit 1 comprises the first storage tank 11 first normally closed solenoid valves 72 and the braking during standstill air chamber 61,62 being connected successively by gas circuit, gas circuit between described the first normally closed solenoid valve 72 and braking during standstill air chamber 61,62 is also connected with admission port and second baroceptor 82 of the second normally closed solenoid valve 73, and described the first normally closed solenoid valve 72, the second normally closed solenoid valve 73 and the second baroceptor 82 are all electrically connected to ECU (Electrical Control Unit) ECU;
Rear service brake unit 2 comprises the second storage tank 12, relay valve 41, the first normally open solenoid valve 71 and the rear service brake air chamber 53,54 being connected successively by gas circuit, also comprise foot brake valves 20, the first admission port of described foot brake valves 20 is connected with the second storage tank 12, its first air extractor duct is connected with the control mouth of described relay valve 41, in the gas circuit between described the first normally open solenoid valve 71 and rear service brake air chamber 53,54, be provided with the first baroceptor 81, described the first normally open solenoid valve 71 and the first baroceptor 81 are all electrically connected to ECU (Electrical Control Unit) ECU;
Front driving brake unit 3 comprises the 3rd storage tank 13, rapid release valve 30 and front driving compressed air brake cylinder 51,52, the second admission port of described foot brake valves 20 is connected with the 3rd storage tank 13, its second air extractor duct is connected with the admission port of described rapid release valve 30, and the air extractor duct of described rapid release valve 30 is connected with front driving compressed air brake cylinder 51,52.
The working process of the utility model integrated form automatic parking brake device is as follows:
one, vehicle normal brake application
During vehicle normal brake application, brake pedal is stepped on, and control pin brake activation valve 20 is opened.The high pressure gas that flow out from the 3rd storage tank 13 are through foot brake valves 20, rapid release valve 30 enter in driving compressed air brake cylinder 51,52.The high pressure gas that flow out from the second storage tank 12 are after foot brake valves 20, relay valve (or load sensing valve) 41 and the first normally open solenoid valve 71 enter in service brake air chamber 53,54.Air pressure in front driving compressed air brake cylinder 51,52, rear service brake air chamber 53,54 constantly raises, and promotes the piston of drg, and wheel is applied to braking.The first normally open solenoid valve 71 no powers in whole braking procedure, keep conducting state.
two, short-term parking
when chaufeur needs the short time during parked vehicle, have to step on braking and do not step on braking and make the vehicle two kinds of situations of stopping.
When chaufeur is stepped on brake pedal and is made vehicle speed reduce to zero, vehicle enters short-term parking pattern automatically, holding brake device is activated, when chaufeur, stepping on brake pedal control pin brake activation valve 20 opens, rapid release valve 30 and relay valve (or load sensing valve) 41 all enters inflated condition, the first normally open solenoid valve 71 is in conducting state, service brake chamber inflated.ECU judges whether to carry out parking action according to Vehicular status signal and sensor signal.If meet braking during standstill condition, ECU sends signal and makes it in off state to the first normally open solenoid valve 71 energisings, and at this moment the rear wheel travelling crane braking system of vehicle starts effect, is equivalent to enter parking state.Chaufeur unclamps foot brake pedal, and the high pressure gas in front driving brake cylinder 51,52 are discharged by rapid release valve 30, and relay valve (or load sensing valve) 41 control end air pressure decline, and relay valve (or load sensing valve) 41 also enters exhaust condition.But because the first normally open solenoid valve 71 is in off state, the air pressure in rear service brake air chamber 53,54 remains unchanged, and vehicle maintains braking mode.
At short notice, chaufeur starts vehicle again, and ECU controls the first normally open solenoid valve 71 and enters conducting state, gives rear service brake air chamber 53,54 venting, brake off.
If chaufeur is not stepped on braking, vehicle is naturally decelerated to and stops, and meets parking condition., due to the unaerated of service brake air chamber, cannot assist braking during standstill by service brake.At this moment parking brake module must get involved to apply braking during standstill power.
three, long-term parking
if vehicle has applied when short-term parking still need to be parked for a long time or vehicle is flame-out, need the intervention of emergency brake system.Specific implementation process is as follows:
When vehicle, park over certain hour or when flame-out, parking brake module is just got involved work.Suppose that now braking during standstill is removed, braking during standstill air chamber 61,62 is in inflated condition.ECU controls the second normally closed solenoid valve 73 and makes it conducting, and 61,62 venting of braking during standstill air chamber, apply braking during standstill to vehicle.
After braking during standstill applies, ECU can determine whether to remove service brake by the judgement to the gradient.If in easy flights, meet parking condition.ECU controls each electromagnetic valve and gets back to initial condition.This time, each electromagnetic valve did not all power on, and guaranteed can park reliably after vehicle stops working.If the gradient is excessive, system sounds a warning to chaufeur, because flame-out the first normally open solenoid valve 71 can be got back to conducting state on heavy grade, vehicle can lose the auxiliary of service brake power, may cause slipping slope.
four, uphill starting is controlled
the utility model is a kind of device of emergency brake system of can integrated control service brake unifying, so can improve the auxiliary of the ability of parking of vehicle on abrupt slope and uphill starting.Specific implementation method is as follows:
Because two module-parking brake modules in the utility model and service brake module can be assisted uphill starting separately, so the auxiliary control of uphill starting can be divided into two kinds of situations.
If system is in short-term braking during standstill state, service braking system effect (the first normally open solenoid valve 71 is in "on" position), emergency brake system is not also got involved (braking during standstill air chamber 61,62 is in inflated condition).At this time the uphill starting underaction of vehicle is mainly implemented by the first normally open solenoid valve 71.First, ECU, by the required braking force size of calculating of ramp angles and vehicle output torque, then removes parking by the pressure gas of controlling in the rear service brake air chamber 53,54 of the first normally open solenoid valve 71 release gradually.Feedback by the first baroceptor 81 changes and to the control of the first 2/2-way normally open solenoid valve 71 on off modes, can realize braking during standstill power and controls more accurately, thereby improves vehicle ride comfort during braking during standstill releasing under different gradient.
If system is in long-term braking during standstill state, emergency brake system effect, service brake is removed.At this time the action of the uphill starting of vehicle is mainly implemented by the first normally closed solenoid valve 72.Due to the difference of braking during standstill air chamber and service brake air chamber structure, parking brake module is by controlling the break-make of electromagnetic valve, to control the inflation rate of compressed air brake cylinder.Braking during standstill power is slowly removed in inflation by braking during standstill air chamber.Equally, also that the speed that the signal of analyzing ramp angles, vehicle output torque and the second baroceptor 82 by ECU is adjusted inflation improves the ride comfort of car ramp starting.
As shown in Figure 2, the ability of parking on abrupt slope in order to improve vehicle, on the automatic parking brake device of integrated form shown in Fig. 1 basis, in the gas circuit between described rapid release valve 30 and front driving compressed air brake cylinder 51,52, be also in series with the 3rd normally open solenoid valve 76, in the gas circuit between described the 3rd normally open solenoid valve 76 and front driving compressed air brake cylinder 51,52, be provided with the 4th baroceptor 84, described the 3rd normally open solenoid valve 76 and the 4th baroceptor 84 are all electrically connected to ECU (Electrical Control Unit) ECU.
When applying short-term parking action, long-term parking action and ramp underaction, the mode of operation of the 3rd normally open solenoid valve 76 is identical with the mode of operation of the first normally open solenoid valve 71, like this, the service brake power that is equivalent to make full use of front and back wheel is assisted emergency brake system, guarantees that vehicle also can have enough braking forces that vehicle is parked on abrupt slope.
