The specific embodiment
In the accompanying drawings, air compressor 3 is by the wet air storage chamber 8 of plumbing connection.Wet air storage chamber 8, back axle air receiver 11 and propons reservoir tube 13 link to each other by pipeline.Propons air receiver 13 is by the lower right corner of plumbing connection brake control valve 21, and back axle air receiver 11 is by the lower left corner of plumbing connection brake control valve 21.Be connected with crosspointer air-pressure gauge 22 between the upper left corner of brake control valve 21 and the lower left corner.Be connected with bilateral check valve 14 between the upper left corner of brake control valve 21 and the upper right corner, the upper left corner of brake control valve 21 also is connected with drg light switch 20.Link to each other by pipeline between two spring brakes 18 and the anti-theft column lock 19, anti-theft column lock 19 is by the lower left corner of plumbing connection brake control valve 21.Spring brake 18 is by ABS regulating control 17 behind the plumbing connection, and back ABS regulating control 17, normally closed solenoid valve 15 and rapid release valve 16 link to each other by pipeline.Normally closed solenoid valve 15 and rapid release valve 16 be the lower left corner by plumbing connection brake control valve 21 all.Rear wheel 25 and front vehicle wheel 26 all are connected with wheel speed sensors 23.The front truck bridging is connected to sideslip sensor 27 and lateral acceleration sensor 28.Bearing circle 30 bars middle part is connected with rotation direction sensor 29.Be connected with hydraulic pressure regulator 32 between petrol storage tank 31 and the clutch assembly 35.Front wheel brake air chamber 1 is by ABS regulating control 2 before the plumbing connection, and preceding ABS regulating control 2 is by the upper right corner of plumbing connection brake control valve 21.
Rotation direction sensor 29, sideslip sensor 27, lateral acceleration sensor 28 and wheel speed sensors 23 constitute the electrical steering stabilization system.Rotation direction sensor 29 is used for the angle of monitoring direction disc spins, helps to determine whether vehicle traveling direction is correct.Sideslip sensor 27 is used to write down the motion of automobile around vertical axis, determines whether wheel skids.The centnifugal force of 28 pairs of turnings of lateral acceleration sensor reacts, and determines whether automobile skids when bend.The wheel speed sensors 23 of wheel is used to monitor the speed of each wheel, determines whether wheel is skidding.
Rotation direction sensor 29, sideslip sensor 27, lateral acceleration sensor 28 and wheel speed sensors 23 are electrically connected with electronic control unit (ECU) 24.Electronic control unit (ECU) the 24th, the control of remote controller operational computations machine.
When automobile brake, wheel speed sensors 23 is sent to electronic control unit (ECU) 24 with the wheel speed signal of each wheel, and control back ABS regulating control 17 prevents wheel lockup.
When automobile parking, electronic control unit (ECU) 24 control anti-theft column locks 19 are in exhaust condition all the time, and spring brake 18 is in locking state (braking during standstill) all the time, reaches the theft-proof effect of wheel lockup.Have only electronic control unit (ECU) 24 control anti-theft column locks 19 to be in closed condition, spring brake 18 could be removed braking during standstill, and automobile just can travel.
When wheel speed signal sensor 23 with wheel speed signal, rotation direction sensor 29 is with the angle signal of bearing circle 36 rotations, sideslip sensor 27 is with the motor message of automobile around vertical axis, the centnifugal force that lateral acceleration sensor 28 produces when turning, determine that whether automobile deliver to electronic control unit (ECU) 24 at the signal that bend skids, electronic control unit (ECU) 24 judges and sends control command according to above-mentioned signal, control ABS anti-lock braking system(ABS) and tractive force control skid control system (TCS) co-operation, reduce tractive force output and provide best braking force nearside wheel and off-side wheel, to improve the stability of direction, prevent the sideslip that oversteer and understeering cause, the rollover accident.
Tractive force control skid control system (TCS) is formed, is played the effect that reduces or increase tractive force output by petrol storage tank 31, hydraulic pressure regulator 32, clutch master cylinder 33, clutch release slave cylinder 34, clutch assembly 35, pedal of clutch 36.
When automobile start, upward slope, acceleration, wheel speed sensors 23 passes to electronic control unit (ECU) 24 with wheel speed signal, when a certain wheel slip, and the machine operation of electronic control unit (ECU) 24 control clutch hydraulic pressure regulators 32.Make clutch assembly 35 be coupled, break away from action, the size of control tractive force output cooperates electronic differential skid control system (EDS) that the wheel that trackslips is imposed optimum braking force, improves tractive force, keeps vehicle run stability.
Electronic differential skid control system (EDS) is made up of back axle air receiver 11, normally closed solenoid valve 15, back ABS regulating control 17, spring brake 18, rear wheel 25, utilize back ABS regulating control 17 to regulate rear wheel 25, change the power distribution of diff, play the skidproof effect of electronic differential.
When automobile start, upward slope, acceleration, wheel speed sensors 23 passes to electronic control unit (ECU) 24 with wheel speed signal.When a certain rear wheel trackslipped, electronic control unit (ECU) 24 control normally closed solenoid valves 15 were opened, and preceding ABS regulating control 2 work impose best braking force for the wheel that trackslips, and improve tractive force, keep vehicle run stability.
Compare when wheel speed sensors 23 is delivered to wheel speed signal in the electronic control unit (ECU) 24, judge a certain wheel wheel speed mal,, tire pressure low (vehicle wheel roll radius is little) is described if this wheel wheel speed is too fast; This wheel wheel speed is too slow, and tire pressure height (vehicle wheel roll radius is big) is described, if when both of these case surpasses setting value then send alerting signal.
When the load change of automobile front and back wheel, the brakig force distribution of ABS regulating control 2 and back ABS regulating control 17 automatic compensation front and back wheel plays the effect that electronic braking force distributes before the control of the Control Software of electronic control unit (ECU) 24.
