Slip after the present invention solves uphill starting and service brake Problem of Failure devises two set control systems, two systems
All realized by same thermoacoustic prime engine device (ECU).Two systems do not work, and only just start when driver needs.
Wherein, the operation principle of control system of slipping after uphill starting is anti-is as follows:
Open ignition switch, if variator is not in reverse gear, System self-test, if in reverse gear position system not self-inspection, every dozen
Ignition switch System self-test is once.After self-inspection normally, system indicator can be bright 5 seconds, then extinguishes, if abnormal finger
Show that very fast frequency scintillation (1 second 2 times) made by lamp.Thermoacoustic prime engine device to receive three below signal simultaneously, just confirms to start working: 1,
After driver opens pass of shying away after preventing, controller receives OFF signal of shying away after preventing；2, variator puts in first gear, and controller receives one
Gear switch signal；3, vehicle is parked on ramp, and thermoacoustic prime engine device receives the signal of Slope Transducer.Thermoacoustic prime engine device startup work

Number), variator is not in reverse gear position, and wheel speed sensors still has pulse signal (slip rate is less than 90%)；2, brake pedal is not
At extreme position, and the push rod of brake chamber is extreme position (being obtained signal by push rod extreme position switch), and variator does not exists
Reverse gear position, and wheel speed sensors still has pulse signal (slip rate be less than 90%)；3, brake pedal is with braking air chamber push rod all
At extreme position, variator is not in reverse gear position, and wheel speed sensors still has a certain degree of pulse signal, and (slip rate is less than
90%).Controller is when confirming that conditions above has one to meet, and controller is considered as now brakes or without air pressure,
Misfunctioning of brake, the function of the most whole brakes has been lost.At this moment controller is by emergency brake solenoid valves.Emergent
The electromagnetic valve that slips after the work process of braking electromagnetic valve is anti-with ramp is identical, but two locking bars of emergency brake electromagnetic valve are relatively to set
Put, pawl can be blocked from both direction, rotate by limiting pawl, prevent power transmission shaft from rotating and reverse, thus play emergent
The effect of braking.
Driving emergency brake control system work after, thermoacoustic prime engine device in spite of receiving contact close signal, display lamp
Chang Liang does not goes out.Only work when self-inspection in this Guan Bi contact.After vehicle stops, ignition switch to be closed, it is again turned on igniting and opens
Close, carry out self-inspection.If self-inspection shows fault, start electromotor, after extension reverse gear travels a small distance, turn off, beat
Open ignition switch self-inspection, until there is no fault.
Control system of slipping after the uphill starting that the present invention provides is anti-can invert at uphill starting limit power transmission shaft, thus rises
To the effect slipped after preventing vehicle, facilitate uphill starting operation；Meanwhile, the driving emergency brake control system provided can be
During former brake fade, automatic locking power transmission shaft, prevent it from rotating, thus play the effect of automatic emergency braking.Two system phases
Coordinate, the security performance of vehicle can be improved, be prevented effectively from the generation of car accident.
