Acceleration signal is transmitted in vehicle-mounted computer 1 by the corresponding distribution of regulating valve 3,3 acceleration transducers 5.
The working principle of the invention and process for using:
1, height controls:
1. a pair bodywork height is demarcated, three different heights, the corresponding three kinds of different modes of three different heights are set；
2. the Three models of bodywork height: " high position ", " middle position ", " low level "；It is selected by rotary switch, it can between mode
To switch at any time.System is externally provided with maintenance mode except 3 kinds of height modes, and system is detached from the control to bodywork height under the mode,
When the mode repairs vehicle for maintenance man, prevent bodywork height adjusting from hurting maintenance man.
3. Three models switch, the gas in air accumulator is pumped into air by controlling the collaborative work of distributing valve by ECU
In spring 41, the inflation of air spring 41 is realized to make the rising of bodywork height；Conversely, collaboration of the ECU by control distributing valve
Work is to be discharged to the air in air spring 41 in atmosphere, the decline of Lai Shixian bodywork height；Finally vehicle body is made to reach predetermined
Highly；
4. vehicle body rises, first rear axle liter, then preceding bridge liter；When vehicle body declines, previous bridge drop, then rear axle drop；System call interception
When, first vehicle body increases again vehicle body and reduces；
5. car door inhibits.When car door or any one unlatching of luggage-boot lid, ECU inhibits the adjustment to bodywork height.
6. static:
Static defining: speed is less than 5km/h；
The static control mode of adjustment in real time is carried out in a manner of bridge control, i.e., for preceding bridge, the height before left front height and the right side
Average value be more than the average value 10mm of setting and after continuing 2s, system starts to carry out height adjustment to preceding bridge；Rear axle is similarly.
When static, when brake pedal is stepped on, system stops the adjustment to bodywork height；
7. dynamic:
Dynamically: Che Su Du≤5km/h
Front-rear axle independently adjusts, the adjustment period be 120s, when a scan period to when, four height of system detection
The numerical value of sensor 6, when their filtered numerical value deviate setting value 8mm, system will carry out vehicle body lifting action, so as to extensive
Bodywork height is answered to setting value.
In vehicle operation, when a failure occurs, vehicle is maintained at pre-fault status operation, and ECU does not control air bullet
Spring 41 fills exhaust.After debugging, system is re-powered, and ECU restores normal after restoring normal.
Turning inhibits function
When dynamic, when steering wheel angle is greater than 30 degree or when gas pedal aperture is greater than 60%, system stops to vehicle
The adjustment of height degree；
When dynamic, when brake pedal is stepped on, system stops the adjustment to bodywork height；
8. after vehicle launch
After vehicle ignition switch is opened, system carries out self-test first, and after self-test no problem, system enters last time and closes hair
Height mode or default to " middle position ", 46 altitude signals of height sensor of system monitoring before motivation, if a certain signal deviates
After the static tolerance of setting height mode, system will be inflated or be vented to air spring 41 automatically.
9. system has suspend mode and arousal function
After vehicle igniting exploitation is closed, ECU, which works on, controls bodywork height (only row does not fill), enters after static 2 minutes
Bodywork height will not be adjusted in dormant state, when suspend mode, and wake-up condition is ignition switch ON.
10. with the whole function of velocity modulation
Controller ECU carries out height adjustment to vehicle body according to the speed height of vehicle.
High-order: speed, which is greater than 40km/h and continues 6s vehicle body, is reduced to middle bit pattern, lower than 35km/h and continues 2s recovery
To high order modes, speed is greater than 100km/h and continues 6s vehicle body and is reduced to low level mode, lower than 80km/h and continue 6s restore to
Middle bit pattern lower than 35km/h and continues 2s and restores to high order modes；
Middle position: speed, which is greater than 100km/h and continues 6s vehicle body, is reduced to low level mode, lower than 80km/h and continues 6s recovery
To middle bit pattern, lower than 35km/h and continues 2s and restore to middle bit pattern.
Low level: keeping height constant in speed lower than 35km/h, restores when speed is higher than 35km/h and continues 6s to middle position
Mode is reduced to low level mode when speed is greater than 100km/h again and continues 6s vehicle body, lower than 80km/h and continue 6s restore to
Middle bit pattern restores when speed is lower than 10km/h to low level mode.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
