Further, the ASR valve is closed type 2/2-way solenoid valve, the solenoid valve there are two port, be respectively as follows: into
Port, gas outlet, air inlet are connected with rear braking gas receiver, and gas outlet is connected with relay valve.
The utility model also adopts the following technical scheme that a kind of controlling party of Anti-slip regulation system with automatic parking function
Method, steps are as follows:
Step 1: stepping on brake pedal 2s deeply when static after vehicle launch, automatic parking function is opened, at this time " A " in instrument
Mark is lighted, if the non-pull-up of hand control valve at this time, abs controller can collect the output of parking braking lamp no signal, then can be controlled
ASR valve no power；If hand control valve pull-up at this time, abs controller, which can collect parking braking lamp, signal output, then can control
ASR valve is powered on, and " P " mark can also be lighted in instrument, and gas can enter rear brake chamber, vehicle in rear braking gas receiver 5
Keep parking；
Pedal > 15% and when needing torque > 200NM step 2: driver steps on the throttle, abs controller can control ASR
Valve power-off, automatic parking function do not act on, and vehicle is in starting-up process, abs controller meeting real-time detection wheel slip λ, vehicle
The definition of wheel slip rateIn formula, VWRepresent vehicle wheel vehicle speeds, V represents actual vehicle speed, when driving, when λ is excessive, then
Abs controller can make to slide by two kinds of control modes that the wheel speed of the moment of torsion control and driving wheel of engine or motor controls
Rate is in normal range (NR), and the wheel speed of the driving wheel controls the unlatching by ASR valve, and gas is braked after entering in rear gas receiver
Gas chamber.
The utility model has the following beneficial effects: the utility model is on the basis of original electric motor coach gas is braked,
ASR and automatic parking system are combined into one.Integration degree is high for this utility model, structure is simple, cost is relatively low.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of Anti-slip regulation system of the utility model with automatic parking function.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, Anti-slip regulation system of the utility model with automatic parking function, including inflating pump 1, condenser 2,
Drier 3, four-loop protection valve 4, rear braking gas receiver 5, brake pedal 6, ASR valve 7, double-way check valve 8, relay valve 9, ABS
Valve 10 and rear brake chamber 11.One end of condenser 2 is connected with inflating pump 1, and the other end is connected with drier 3；Four circuits are protected
One end of shield valve 4 is connected with drier 3, and the other end is connected with brake pedal 6；One air inlet of double-way check valve 8 and braking
