Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As it is shown in figure 1, one loader automatic parking system of the present invention, control box 1, electronics manual brake button 4 He including ECU
Hand brake valve block 5；ECU controls box 1 and is connected with gear box control unit 7；Electronics manual brake button 4 controls box 1 with ECU and is connected, electricity
Sub-manual brake button 4 is connected with the electromagnetic switch spool 5-1 in hand brake valve block 5, hand brake valve block 5 and parking system in change speed gear box
Dynamic device 6 is connected, and electromagnetic switch spool 5-1 and ECU control unit 1 is connected.
On the basis of said structure, ECU of the present invention is controlled box 1 and is cut by the power of II line with gear box control unit 7
Changing port to be connected, ECU controls box 1 can control gear box control unit power cut port, it is achieved power cut.ECU controls
Box 1 is connected with the tach signal port of gear box control unit 7 by III line, and ECU controls box 1 can pass through change speed gear box control
Unit 7 processed gathers the signals of rotational speed sensor of change speed gear box.ECU of the present invention controls box 1 by IV line and control unit of engine 8
Tach signal port be connected, ECU controls box 1 can gather engine rotational speed signal, the present invention by control unit of engine 8
ECU control box 1 can also connect automatic parking display lamp 9.During automatic parking functional realiey, control unit 1 is lighted and is automatically stayed
Car display lamp 9.ECU control box 1 can also connect stopping brake display lamp 3, and institute's stopping brake display lamp 3 is pressed with electronics parking brake
Button switch 4 is connected.During stopping brake, ECU controls box 1 and outputs current to stopping brake display lamp 3, lights display lamp.
The present invention is further provided with automatic parking press button 2, controls box 1 with ECU and is connected, by automatic parking button
Switch 2 switching automatic or manual park mode.When being not desired to use automatic parking, application is closed button and is carried out implementation pattern switching,
When automatic parking press button 2 is closed, realize stopping brake by electronics manual brake button 4 and hand brake valve 5.The most manually stay
Car pattern has precedence over automatic parking pattern, under automatic parking press button 2 on-state, connects electronics manual brake button 4 and switchs
It is braked by force.
Automatic parking system of the present invention is to increase ECU on the basis of original electronics parking brake to control box, by automatically controlled program
Realize automatic parking, and this function can realize the switch of function by button.Patent of the present invention is by automatically controlled liquid
Mode realizes the automatic parking function of loader.Summary technical scheme, operation principle of the present invention is as follows: when automatic parking merit
When energy button 2 is closed, driver can realize stopping brake by electronics manual brake button 4.When connecting electronic hand
Stopping button 4, its transmission signal controls box 1 to ECU, and ECU controls box 1 and exports an electric current and change to the electromagnetism on hand brake valve block 5
To spool 5-1, making spool commutate, high pressure liquid force feed flows to parking brake 6 and realizes stopping brake, and the box 1 of ECU control simultaneously exports
Electric current, to stopping brake display lamp 3, lights display lamp.Now vehicle is in parking brake condition.When closing electronics manual brake button 4
After, car braking status releasing, vehicle can normally work.
After pressing automatic parking button 2, electronics manual brake button 4 is closed simultaneously, and automatic parking function is
Can start working, now automatic parking display lamp 9 is bright.Now ECU control box 1 gathers change speed gear box by gear box control unit 7
Signals of rotational speed sensor, after making vehicle be completely in halted state 1s by service braking system brake, and start
Machine is in idling mode, and namely ECU control box 1 collects rotating speed sensor for gearbox does not has tach signal 1s and electromotor
Being in idling mode, ECU controls box 1 and exports electric current to the electromagnetic switch spool 5-1 in hand brake valve block 5 so that it is commutation, high pressure
Hydraulic oil flow is to change speed gear box hand brake, it is achieved stopping brake.Meanwhile, ECU control box 1 outputs signal to gear box control unit
Power cut port, it is achieved power cut.Now vehicle is in power cut and parking brake condition.Now, driver is permissible
Loosen completely, be not required to be operated manually realizing stopping brake button.When driver gently steps on the gas, ECU controls box 1 by starting
Machine control unit 8 gathers engine rotational speed signal, and when engine speed rises 100r/min, ECU controls box 1 and stops output electricity
Stream, to solenoid directional control valve 5-1, now releases stopping brake, and recovers gearbox dynamic transmission, and now vehicle can normally work.
Certainly, above-described embodiment is only the preferred version of the present invention, is specifically not limited thereto, on this basis can basis
It is actually needed to make having and adjusts targetedly, thus obtain different embodiments.Owing to mode in the cards is more, this
In illustrate the most one by one.
