The specific embodiment
As shown in Figure 1 with the vehicle body jacking system of passenger door state interlock; This comprises three levelling valves 18; Three levelling valves 18 are located at passenger vehicle front and back bridge wheel four air bags 16 everywhere through 17 controls of four normal open electromagnetic valves respectively; The control mouth of three levelling valves 18 is connected in the air extractor duct of normally closed solenoid valve 19 respectively; The admission port of the admission port of this normally closed solenoid valve 19 and three levelling valves 18 all is connected with air chamber 20; Control linkages are in the control output end of ECU respectively for normally closed solenoid valve 19, normal open electromagnetic valve 17, and the control input end of this ECU is connected with vehicle body direction switch 3 respectively, recover normal level switch 4, offside door signal 15, offside door signal 14 and system works master cock 13, are connected in series battery isolator control 2 between this system works master cock 13 and the storage battery 1; During the opening and closing of ECU control offside door the left side vehicle body interlock falls, rises, the right side vehicle body fell, rises interlock when ECU controlled opening and closing of offside door.The vehicle body direction switch is one to be used to control the single pole double throw switch that the left and right side vehicle body goes up and down.There is buzzer phone 11 control output end of ECU also control linkage; Be provided with red system trouble lamp 5 and yellow system relay indicating light 6 between ECU and the system works master cock; The control input end of ECU also is connected with car speed sensor 8; This car speed sensor links to each other with combination instrument 7, also is provided with infrabar alarm switch 12 in the system.
This system control device may command vehicle is in five kinds of states: vehicle body raises, normally height, vehicle body reduce, inclining in the vehicle body left side, inclines in the vehicle body right side.
When needs use this control system; Elder generation's opening power main supply switch 2, battery isolator control is opened system works switch 13 after connecting again, and system begins self check; System works indicator lamp and system failure alarm lamp extinguish after bright 2 seconds simultaneously; If do not extinguish, show that there is fault in system, do not work by any on-off system before not extinguishing.
When system did not work, vehicle body was in normal height, and control ECU does not externally export any electric current, and system alarm lamp, relay indicating light, buzzer phone are not worked.
When upwards pinning vehicle body direction switch 3, during No. 275 line moment bonding, No. 285 line is externally exported the 24VDC electric current, the normally closed solenoid valve adhesive, and airbag aeration, vehicle body rises, system works indicator lamp Chang Liang, system's buzzer phone is interrupted sounding.When trip switch 3, No. 285 line loss of voltage, 286 and No. 289 line is exported the 24VDC DC current simultaneously, and the normal open electromagnetic valve begins pressurize, and vehicle body keeps current height.Repeat above-mentioned action, vehicle body just begins to go up assorted, up to being raised to maximum height.
When pinning vehicle body direction switch 3 downwards, during No. 276 line moment bonding, 286 (289), 287 (288) numbers line is externally exported the 24VDC electric current, and the normal open electromagnetic valve is in exhaust condition, and vehicle body descends, and system works indicator lamp Chang Liang, buzzer phone are interrupted sounding.When this moment during trip switch 3,287 (288) numbers line loss of voltage only have 286 and No. 289 lines to export the 24VDC vdc simultaneously, and the normal open electromagnetic valve begins pressurize, and vehicle body keeps current height.Repeat above-mentioned action, vehicle body just begins to descend, up to dropping to minimum altitude.
When offside door was opened, offside door signal 14 obtained signal, and 286 and No. 287 line is externally exported the 24VDC electric current always, and right side normal open electromagnetic valve is in exhaust condition always, and the vehicle body right side descends at once.No. 289 lines are exported the 24CDV voltages simultaneously, and left side normal open electromagnetic valve is in packing state, and the left side vehicle body remains unchanged.System works indicator lamp Chang Liang, buzzer phone are interrupted sounding.Close the door behind the key when pressing the right side, offside door signal 14 breaks off, and 286 and 287 cut off the power supply immediately, no longer export 24VDC voltage, and right side normal open electromagnetic valve is in normal open state.No. 285 lines are not exported 24VDC voltage yet simultaneously, and normally closed solenoid valve is closed, and the right side is in the normal height process of recovering by levelling valve.This moment, the left side still kept packing state constant, left side normally closed solenoid valve pressurize signal relief when having detected GES, and promptly 289 at defeated 24VDC voltage again, and vehicle body recovers normal height.
When offside door was opened, offside door signal 15 obtained signal, and 289 and No. 288 line is externally exported the 24VDC electric current always, and left side normal open electromagnetic valve is in exhaust condition always, and the vehicle body left side descends at once.No. 286 lines are exported the 24CDV voltages simultaneously, and right side side normal open electromagnetic valve is in packing state, and the right side vehicle body remains unchanged.System works indicator lamp Chang Liang, buzzer phone are interrupted sounding.On the left of pressing, close the door behind the key, offside door signal 15 breaks off, and 24VDC voltage is no longer exported in 289 and 288 outages immediately, and left side normal open electromagnetic valve is in normal open state.No. 285 lines are not exported 24VDC voltage yet simultaneously, and normally closed solenoid valve is closed, and the left side is in the normal height process of recovering by levelling valve.This moment, the right side still kept packing state constant, and right side normally closed solenoid valve pressurize signal relief promptly 286 is no longer exported 24VDC voltage when having detected GES, and vehicle body recovers normal height.
No matter when, moment pushes when recovering normal level switch 4, and 275, No. 276 lines are bonding simultaneously, and normally closed solenoid valve and normal open electromagnetic valve all will cut off the power supplys, and system is in off position, and car sound relies on levelling valve to recover automatically normally highly.
After System production time surpasses 30 minutes, system will quit work automatically, and vehicle body recovers normal height, the damage in order to avoid electromagnetic valve is switched on for a long time.
When the speed of a motor vehicle surpasses 10 kilometers/hour, all inoperative by any key except recovering normal height key.After the speed of a motor vehicle reached 15 kilometers/hour, system quit work, and vehicle body recovers normal height automatically.
When system's generation internal fault, system failure lamp warning (redness) will be glimmered, and system S buzzer phone stops sounding, and system will quit work automatically, and vehicle body recovers normal height automatically.
