Automatic parking system and its control method.
The present invention adopts the following technical scheme: a kind of automatic parking system, including inflating pump, condenser, drier, four times
It protects valve, brake gas receiver, brake pedal, proportion relay valve, abs valve and rear brake chamber afterwards in road；The one of the condenser
End is connected with inflating pump, and the other end is connected with drier；One end of the four-loop protection valve is connected with drier, the other end with
Brake pedal is connected；Described abs valve one end is connected with proportion relay valve, and the other end is connected with rear brake chamber.
Further, the proportion relay valve is gas control and automatically controlled integrated relay valve.
Further, voltage-type baroceptor is provided at the gas outlet of the proportion relay valve.
The present invention also adopts the following technical scheme that a kind of control method of automatic parking system, it is characterised in that: step is such as
Under:
Step 1: stepping on 6 2s of brake pedal deeply, automatic parking function is opened, at this time in instrument when static after vehicle launch
" A " mark is lighted, if the non-pull-up of hand control valve at this time, entire car controller can collect the output of parking braking lamp no signal, then can
Control proportion relay valve no power；If hand control valve pull-up at this time, entire car controller, which can collect parking braking lamp, has signal defeated
Out, illustrate that vehicle is not on parked state at this time, then can control proportion relay valve energization, input 900mA- to proportion relay valve
The electric current of 1200mA, then proportion relay valve can export the air pressure of 0.55MPa-0.85MPa, while the gas outlet of proportion relay valve
Place's in-built electrical pressure type baroceptor can sense the air pressure of 0.55MPa-0.85MPa, the voltage value of output be 2.5V-3.6 it
Between, illustrate that automatic parking function is normal, " P " mark is also lighted therewith in instrument, and gas brakes gas after entering in rear gas receiver
Room, vehicle keep parking；If in-built electrical pressure type baroceptor does not sense air pressure or only a small amount of gas, vehicle
Controller can report automatic parking system failure, and " P " flashes in instrument；
Pedal > 15% and when needing torque > 200NM step 2: driver steps on the throttle, entire car controller can control ratio
Example relay valve power-off, automatic parking function do not act on, if in-built electrical pressure type baroceptor senses that air pressure is 0.55MPa-
Between 0.85MPa, then entire car controller can report automatic parking system failure, and " P " flashes in instrument；
Step 3: vehicle is when waiting traffic lights or temporary stop platform, this period control method is as described in the first step.
The invention has the following beneficial effects: on the basis of the braking of original electric motor coach gas, relay valve is changed to
Proportion relay valve, operation of the present invention is simple, easy to use.
Detailed description of the invention:
Fig. 1 is automatic parking system structural schematic diagram of the present invention.
Fig. 2 is the interface diagram of automatic parking system proportion relay valve of the present invention.
Fig. 3 is the big logotype of gas outlet air pressure of automatic parking system proportion relay valve of the present invention.
Specific embodiment:
The present invention will be further described below with reference to the drawings.
As shown in Figure 1, automatic parking system of the present invention includes inflating pump 1, condenser 2, drier 3, four-loop protection valve
4, gas receiver 5, brake pedal 6, proportion relay valve 7, abs valve 8 and rear brake chamber 9 are braked afterwards.It one end of condenser 2 and beats
Air pump 1 is connected, and the other end is connected with drier 3；One end of four-loop protection valve 4 is connected with drier 3, the other end and braking
Pedal 6 is connected；8 one end of abs valve is connected with proportion relay valve 7, and the other end is connected with rear brake chamber 9.
As shown in Fig. 2, proportion relay valve 7 of the invention is gas control and automatically controlled integrated relay valve.In original pneumatic servo
Increasing automatically controlled control mouth on the basis of valve, this control mouth can release the control the size of air pressure according to the size of electric current, thus
The size of 7 gas outlet air pressure of proportion relay valve is controlled, as shown in Figure 3.After automatically controlled control mouth failure, conventional air pressure control
Donsole still can control 7 output pressure of proportion relay valve.In addition, there is a built-in voltage at the gas outlet of proportion relay valve 7
Formula baroceptor can feed back corresponding voltage according to the size of gas outlet air pressure.If vehicle needs the feelings of automatic parking
Under condition, then the electric current of 6 mouthfuls of comparative example relay valve 7 input responses can 2 mouthfuls of control output end air pressure, built-in sensor can
Whether acted on feedback proportional relay valve 7.
In above embodiment, using can also as other implementation methods with vehicle control unit controls proportion magnetic valve 7
Individually a controller to be added to be controlled.
In above embodiment, the voltage-type baroceptor in use ratio relay valve 7 carries out detection air pressure, as it
His implementation method, can another aerating pressure sensor be controlled.
Inflating pump 1, condenser 2, drier 3, four-loop protection valve 4, rear braking gas receiver 5, brake pedal 6, abs valve
8, the working principle of rear brake chamber 9 and inflating pump, condenser, drier, four in prior art microbus air braking system
Loop protection valve brakes gas receiver, main brake valve, abs valve, rear brake chamber afterwards.Working principle is identical, therefore no longer to the present invention
It is repeated.
The control method of automatic parking system of the present invention are as follows:
Step 1: stepping on 6 2s of brake pedal deeply, automatic parking function is opened, at this time in instrument when static after vehicle launch
" A " mark is lighted.If the non-pull-up of hand control valve at this time, entire car controller can collect the output of parking braking lamp no signal, then can
Control 7 no power of proportion relay valve；If hand control valve pull-up at this time, entire car controller, which can collect parking braking lamp, has signal defeated
Out, illustrate that vehicle is not on parked state at this time, then can control the energization of proportion relay valve 7, be inputted to proportion relay valve 7
The electric current of 900mA-1200mA, then proportion relay valve 7 can export the air pressure of 0.55MPa-0.85MPa, while proportion relay valve 7
Gas outlet at in-built electrical pressure type baroceptor can sense the air pressure of 0.55MPa-0.85MPa, the voltage value of output is
Between 2.5V-3.6, illustrate that automatic parking function is normal, " P " mark is also lighted therewith in instrument, and gas can be into rear gas receiver 5
Enter rear brake chamber 9, vehicle keeps parking.If in-built electrical pressure type baroceptor does not sense air pressure or only a small amount of
Gas, then entire car controller can report automatic parking system failure, and " P " flashes in instrument.
Pedal > 15% and when needing torque > 200NM step 2: driver steps on the throttle, entire car controller can control ratio
Example relay valve 7 powers off, and automatic parking function does not act on.If in-built electrical pressure type baroceptor senses that air pressure is
Between 0.55MPa-0.85MPa, then entire car controller can report automatic parking system failure, and " P " flashes in instrument.
Step 3: vehicle is when waiting traffic lights or temporary stop platform, this period control method is as described in the first step.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
It for member, can also make several improvements without departing from the principle of the present invention, these improvement also should be regarded as of the invention
Protection scope.
