Place, now, vehicle control unit controls buzzer sends the second preset sound, and to prompt driver turn to finish, driver can drive
Car leaves.
It should be pointed out that the automobile in the utility model second embodiment includes the vapour in above-mentioned first embodiment
The full content of vehicle hydraulic system.
Reference picture 2, in the utility model 3rd embodiment, there is provided a kind of car hydraulics control method, application
In above-described car hydraulics, this method includes：
Step 1, control car hydraulics turn to the opening position perpendicular with automobile chassis.
Step 2, control the first motor 9 to be rotated towards first direction, and obtain the height of the first oil mass in first hydraulic cylinder 2
Degree.
Step 3, when first oil mass highly reaches the first preset height, first motor 9 is controlled towards the
Two directions rotate, and obtain the height of the second oil mass in second hydraulic cylinder 4.
Step 4, when second oil mass highly reaches the second preset height, first motor 9 is controlled to stop
Rotate, and control wheel 7 to be rolled towards preset direction.
, it is necessary to which driver stops automobile to parallel with parking stall before the step in carrying out the utility model embodiment
Opening position, and require that the position of parking of automobile can ensure that automobile can stop to parking stall completely after being moved transversely
In, it will not be scratched with other vehicles.
The car hydraulics control method of the utility model 3rd embodiment, it may be that carried out after on automobile
Use.In step 1, it is by being arranged on to control car hydraulics to rotate as the perpendicular opening position of automobile chassis
What the cursor on automobile chassis was controlled.By controlling cursor to rotate as the perpendicular opening position of automobile chassis i.e.
Can.
In step 2, the acquisition to the first oil mass height in first hydraulic cylinder 2 is by being arranged on first hydraulic cylinder 2
What the first interior displacement transducer was obtained, first displacement transducer is connected with entire car controller.When first oil mass is high
When degree reaches the first preset height, then it is assumed that the oil mass of suction disclosure satisfy that the oil needed for automobile is jacked up in first hydraulic cylinder 2
Amount requires.
In step 3, the acquisition to the second oil mass height in second hydraulic cylinder 4 is by being arranged on second hydraulic cylinder 4
What interior second displacement sensor was obtained, the second displacement sensor is connected with entire car controller.When the automobile hydraulic system
When the wheel 7 of system contacts with ground, automobile is not jacked up also, when the second oil mass highly reaches the second preset height, can be recognized
It is set to automobile to be jacked up by the car hydraulics.
In order to allow the operator to recognize the first oil mass in first hydraulic cylinder 2 highly reach the first preset height with
And the second oil mass in second hydraulic cylinder 4 highly reaches the second preset height, entire car controller can control buzzer to send difference
The 3rd preset sound and the 4th preset sound.Driver then performs step 3 after the 3rd preset sound is heard；Driver
When hearing four preset sounds, then step 4 is performed.
In step 4, control wheel 7 to be rolled towards preset direction, be to control to realize by the rotation to the second motor
What wheel 7 rolled.Because the output shaft of the second motor rotates coaxially with wheel 7, thus, it is possible to realize by the second driving
The rotational band motor car wheel 7 of motor rolls.
Further, in the utility model 3rd embodiment, the car hydraulics control method also includes：
When the wheel 7 is rolled to predetermined position, control stop valve 51 is opened.
Herein, determine that wheel 7 is rolled to predetermined position city straight turning to be correctly parked in inside parking stall, it is by setting
The distance between wheel 7 and stop line that the range sensor on wheel 7 senses is put to be judged.Meanwhile driver
It is also assumed that go confirm whether vehicle has been parked in parking stall, artificial being sent by button to entire car controller is opened
The signal of stop valve 51.
In above-mentioned steps, because vehicle has correctly been parked in inside parking stall when control stop valve 51 is opened, now, need
The car hydraulics are recovered to original state.It is then desired to stop valve 51 is opened so that the oil in second hydraulic cylinder 4 returns
It flow in fuel tank 1, and then causes vehicle to recover the contact between ground.
Further, in the utility model 3rd embodiment, the car hydraulics control method also includes：
Obtain the working time that the stop valve 51 is opened.
When the working time reaching the first preset time, the stop valve 51 is controlled to close, and control automobile liquid
Pressure system turns to the opening position parallel with automobile chassis.
It is identical due to flowing into the oil mass in second hydraulic cylinder 4 every time, in design, pre-trial goes out stop valve
51 unlatching times how long enabled to the oil stream in second hydraulic cylinder 4 to be back in fuel tank 1.Reached when the time that stop valve 51 is opened
During to the first preset time, then it is assumed that the oil in second hydraulic cylinder 4 is flow back into fuel tank 1 completely, now, full-vehicle control
Device control stop valve 51 is closed.And the 5th preset sound is sent by buzzer and reminds driver.Driver is hearing the 5th
After preset sound, by pressing closing button, vehicle control unit controls turning arm is rotated as the parallel opening position of vehicle chassis
Go.
The utility model 3rd embodiment provide car hydraulics control method, with above-mentioned car hydraulics and
Automobile has identical technique effect., can by the control method of the car hydraulics of the utility model 3rd embodiment
Solution is in side when stop because the bit length that stops it is shorter can not orderly shutdown the problem of.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
