Description
Technical field
The present invention relates to a kind of control setup that is used for uphill starting; Relate in particular to a kind ofly be used to drive a vehicle, uphill starting control setup and method of application thereof under the braking during standstill, specifically be applicable to the uphill starting of automobile under driving, braking during standstill that automatic transmission with hydraulic torque converter (being called for short AMT) is housed.
Background technology
At present, the uphill starting under the braking mode comprises that the service brake down ramp is started to walk and the braking during standstill down ramp is started to walk these two kinds.
Start to walk for the service brake down ramp: part is equipped with the vehicle of AMT; Adopt the method for constant time lag service brake; Promptly when stepping on the driving engine acceleration pedal, brake system keeps a period of time the braking of (regularly several seconds) automatically, and time-delay finishes the back brake off, accomplishes starting; As in the timing time limit, to accomplish starting, and do not take brake measure, vehicle then can slip the slope and retreat.This method is only applicable to the of short duration parking under the service brake.Shortcoming: time-delay braking only can be controlled the starting of service brake, if the long period parks, then can not work, and still needs hand braking, clutch, engine throttle compounding practice this moment, and operation easier is higher.
Start to walk for the braking during standstill down ramp: also have vehicle to adopt the method for starting of braking during standstill; Promptly putting down hand brake valve earlier carries out the ramp and parks; Then when starting; Car load electric-control system (abbreviating VECU as) is through being contained in the filling of the real-time controlling spring air chamber of ramp electromagnetic valve between differential type relay valve, the spring air chamber, exhaust, realizing removing and the purpose of braking, thereby accomplishes uphill starting.The long period that this method is only applicable under the braking during standstill stops.Shortcoming: only can control braking during standstill; If the short period stops, as through road junction ruddiness green light the time, the parking mode that adopt this moment can only be service brake; Recurrence is during the step so; This kind uphill starting device just can not work, and still needs hand braking, clutch, engine throttle compounding practice this moment, and operation easier is higher.
Above-mentioned control method, or control service brake separately, or control braking during standstill separately, can not satisfy various applying working condition down ramp starting requirements, field of application is narrower.
The Chinese patent patent No. is ZL200510020919.8; Granted publication day is that the patent of invention on June 24th, 2009 discloses a kind of device and method that prevents vehicle start-backing when ascending; This device comprises brake pedal, micro-control unit, power-transfer clutch and two-position inductor, and said two-position inductor is installed on the said brake pedal, responds to the residing ad-hoc location of said brake pedal; And the signal of the residing ad-hoc location of brake pedal sent to said micro-control unit; Said micro-control unit makes power-transfer clutch carry out binding operation, and driving engine is given the automatic transmission with hydraulic torque converter output torque, makes vehicle start.Though retreat when this invention can prevent the vehicle driving up starting to a certain extent, it still has following defective:
At first, the uphill starting apparatus and method that this invention is adopted only can realize the purpose of uphill starting under the driving braking mode, and can't under the braking during standstill state, use, thereby it can not possess the function of driving, the starting of braking during standstill down ramp simultaneously;
Secondly, this was invented before using must set an equilibrium point, and what this equilibrium point was represented is the balance between brake control power and the gradient resistance; Have only this equilibrium point of arrival, vehicle just can carry out driveaway operation, but the cooresponding gradient resistance of this equilibrium point is a calculation and object with 30 degree ramps; And in practical application, the ramp of various angles all exists, thereby there is big parameter in the gradient resistance that this invention relied on; Can not adapt to all ramps; And the brake control power of each car also can change with different operating modes or load, thereby also there is big parameter in the brake control power that this invention relied on; Can not adapt to all operating modes, so its field of application is narrower;
Once more, this invention is to pass through loosen the brake device pedal earlier with brake off power, when removing to a certain degree; After promptly arriving equilibrium point, just make vehicle start, this moment, braking force was removed; Gradient resistance is constant, and vehicle is at the early-stage, as the vehicle of first starting; Its dynamics of advancing is difficult to just to overcome gradient resistance, thereby this moment, vehicle had big possibility the slope to occur slipping dangerous operating mode such as to retreat, and safety that therefore should invention is lower.
Summary of the invention
The objective of the invention is to overcome narrower, the controlled relatively poor defective of function, field of application and the problem that can not possess the starting of driving, braking during standstill down ramp simultaneously that exist in the prior art, provide a kind of and can possess simultaneously that wider, controlled stronger being used to of function, field of application that driving, braking during standstill down ramp start to walk driven a vehicle, uphill starting control setup and method of application thereof under the braking during standstill.
For realizing above purpose; Technical solution of the present invention is: be used to drive a vehicle, the uphill starting control setup under the braking during standstill; This device comprises four-loop protection valve, hand brake valve, foot brake valve and spring air chamber; The admission port of said four-loop protection valve communicates with the air extractor duct of Air compressor through air dryer; The air extractor duct of four-loop protection valve communicates with hand braking air tank, foot brake air tank, and the other end of hand braking air tank communicates with the spring air chamber through hand brake valve, and the other end of foot brake air tank communicates with the spring air chamber through the foot brake valve;
