Description
Technical field
The utility model belongs to vehicle electronic control air suspension, is specifically related to a kind of electronic control air suspension height adjustable control setup.
Background technology
Traditional electronic control air suspension is generally made up of height sensor, controller ECU, electric air pump, storage tank, electromagnetic valve and air bellow, and its control policy is: one is system automatic height adjustment; Two chaufeurs when being static systems control the lifting of vehicle, are convenient to passenger up and down or goods easy to loading and unloading.Its shortcoming is: one, storage tank is inflated directly in air bellow, and storage tank internal pressure is very high, and vertical motion is obvious, easily affects traveling comfort and the safety of chaufeur and passenger when dynamic; Two, the adjustment of height cannot be carried out to improve the stability by safety and high-speed road conditions of severe road conditions according to road conditions in time; Three, without velocity correlation characteristic, during speed height, stability and the safety of Vehicular system is affected; Four, dryer is changed frequent, and cost is high; Five, integrated level is little, and connecting line and joint cause installing space to reveal greatly and easily more.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the purpose of this utility model is, provides a kind of electronic control air suspension height adjustable control setup,
The electronic control air suspension height adjustable control setup that the utility model provides, be connected with the CAN of vehicle, it comprises controller, mode selector, storage tank, 4 air bellows, electric air pump device, 5-linked valve gear, described controller one end and mode selector, the CAN of vehicle connects, the other end respectively with 4 air bellows, electric air pump device, 5-linked valve gear connects, and described 4 air bellows are respectively left front air bellow, left back air bellow, right front air bellow, right back air bellow, described storage tank is connected with 5-linked valve gear, and storage tank respectively with left front air bellow, left back air bellow, right front air bellow, right back air bellow is connected in parallel, and described storage tank is provided with left front pressure balance valve with corresponding respectively on the circuit of 4 air bellow parallel connections, left back pressure balance valve, right front pressure balance valve, right back pressure balance valve, and left front height sensor, left back height sensor, right front height sensor, right back height sensor.
By storage tank and left front air bellow, right front air bellow, left back air bellow, right back air bellow is in parallel, change traditional by storage tank to 4 air bellow air feed strategies. the intake and exhaust electromagnetic valve that 5-linked valve is integrated with 4 air bellows (left frontly fills exhaust solenoid valve, right frontly fill exhaust solenoid valve, left backly fill exhaust solenoid valve, right backly fill exhaust solenoid valve), and add the electromagnetic valve that 1 control storage tank fills exhaust, the intake and exhaust channel of 5-linked valve adds a pressure sensor, be used for the pressure of monitoring 4 air bellows and storage tank, therefore the integrated risk greatly reducing installing space and system leakage of the height of 5-linked valve.Electric air pump device is integrated with airfilter, air compressor unit, dryer, check valve, pressure Pneumatic valve and exhaust solenoid valve; Dryer absorbs the moisture in air when air bellow is inflated, still by dryer during air bellow exhaust, taken away moisture wherein, possessed blowback function, therefore greatly reduced the number of times changing dryer; Controller ECU communicates with car load CAN signals such as obtaining car speed gate, the height of suspension is passed to controller ECU by left front height sensor, right front height sensor, left back height sensor, right back height sensor in real time, and ECU fills exhaust in conjunction with related control strategies to corresponding air bellow (left front air bellow, right front air bellow, left back air bellow, right back air bellow) according to suspension height information; Mode selector is remote controller or touch-screen or button, and chaufeur carries out the selection of associative mode according to road conditions and personal inclination.Therefore depth-adjustment feature is as follows:
1. height mode is selected
Height mode is carried out the selection of several height mode according to riving condition by chaufeur, height mode selection can be the touch-screen of Vehicular navigation system, also can be hand-held remote controller or button, system can according to customer demand setting height pattern, generally has " high position " pattern being applicable to back road and severe road surface, " cross-country " pattern being applicable to national highway, is applicable to " comfortable " pattern of urban highway and is applicable to express highway " at a high speed " pattern.System adds " setting " key in addition, and driver and crew can set parameters such as above-mentioned height, vehicle speed thresholds.
2. velocity correlation
By gathering vehicle speed signal or the adjustment bodywork height that communicates with CAN, thinking motoring condition at speed of a motor vehicle >5km/h, thinking quiescence at speed of a motor vehicle <5km/h;
" high position " pattern: height of car is+40mm (in normal level for 0).As speed of a motor vehicle >40km/h, suspension is changed to cross-country pattern by high order modes automatically, changes highly thereupon.Just high order modes can not be selected more than during 20km/h in the speed of a motor vehicle;
" cross-country " pattern: height of car is+20mm.As speed of a motor vehicle >100km/h, height reduction to 0 (normal level); Speed of a motor vehicle <70km/h, highly gos up to+20mm;
" comfortable " pattern: height of car is 0mm.When speed of a motor vehicle >100km/h is more than 20s, height reduction to-15mm, speed of a motor vehicle <70km/h more than 20s time, highly rise to 0, if during speed of a motor vehicle <35km/h, go up highly immediately to 0;
" at a high speed " pattern: height of car is-15mm.When speed of a motor vehicle >120km/h is more than 20s, height reduction is to-15mm; When speed of a motor vehicle <90km/h is more than 20s, highly go up to-15mm, if during speed of a motor vehicle <35km/h, go up highly immediately to-15mm.
3. air feed order
As speed of a motor vehicle <35km/h, the preferential air feed of storage tank (if having enough pressure in storage tank), otherwise electric air pump starts air feed, as speed of a motor vehicle >35km/h, the preferential air feed of electric air pump, prevents from impacting obviously during speed height;
During stationary vehicle, ECU can control separately any air bellow and fill exhaust, when 4 air bellows need exhaust and inflation respectively, should first complete gas replenishment process and then be vented.
Pressure sensor monitoring air bellow and storage tank air pressure.
The electronic control air suspension height adjustable control setup that the utility model provides, its beneficial effect is, this control system decreases the risk of leakage of installing space and system, and the characteristics such as height mode selection and velocity correlation add travelling comfort and the safety of Vehicular system.
