Description
Technical field
The present invention relates to a kind of commercial car switch valve more particularly to a kind of automatically controlled relay valves with bilateral one-way function.
Background technology
At present, electronic brake system (EPB:Electrical Park Brake) refer to facing in driving conditions
Long when property braking function after when property is braked and stopped combines, and the skill of stopping brake is realized by electronic control mode
Art.Automobile automatic collision avoidance system (automatic bump-shielded system of the automobile), is to prevent
A kind of intelligent apparatus that automobile collides.It can have found that it is likely that automatically the vehicle to collide with automobile, pedestrian or other
Obstructing objects send alarm or take braking simultaneously or evade the measures of grade, generation to avoid collision.
ESC full name Electronic Speed Controller, are body electronics stabilitraks.Automotive electronics
Stabilizing control system is the new active safety system of vehicle, is anti-lock braking system in automobiles (ABS) and polling power controlling system
System (TCS) function further expands, and on this basis, adding Vehicular turn, yaw rate sensor, direction finding add when driving
Velocity sensor and steering wheel angle sensor, the driving force and brake force of wheel around being controlled by ECU, it is ensured that vehicle
Traveling lateral stability.The system is made of sensor, electronic control unit (ECU) and actuator three parts, is passed through
Electronic control unit monitors motoring condition, and engine and braking system to vehicle carry out intervention control.Typical automobile
Electronic stabilizing control system mainly includes 4 wheel speed sensors, wheel steering angle transducer, side acceleration on a sensor
Sensor etc., executable portion then include Conventional braking systems (vacuum booster, pipeline and brake), fluid pressure governor etc., electricity
Sub-control unit links with engine management system, and engine power can be exported and intervened and adjusted.
This set system mainly controls longitudinal direction of car and lateral stability, ensures consciousness row of the vehicle according to driver
It sails.The system can cooperate with Engine ECU, when driving wheel skids by comparing the rotating speed of each wheel, electronic system
Judge whether driving wheel skids, reduce throttle inflow amount automatically at once, reduce engine speed so as to reduce power output,
The driving wheel of skidding is braked.Skidding can so be reduced and keep most suitable dynamic between tire and ground grip
Power exports, at this time no matter how oil supply, slipping phenomenon will not all occur for driving wheel.
The system is embodied in terms of lateral stability of cars is ensured when system is passed by rotary angle transmitter, transverse acceleration
The signal discovery vehicle of sensor and wheel speed sensors have occurred understeer or it is excessive when, system can control single or multiple vehicles
Wheel is braked, to adjust automobile changing Lane or the body gesture when excessively curved, make automobile changing Lane or it is excessively curved when
It can be more steady and safe.
But there are following defects for existing technology：
Three of the above electronic control system is required to realize the purpose of braking by executing agency, at present in commercial car
In air braking system, executing agency is generally used as by the split type scheme of double-way check valve+ASR valves+relay valve to realize electricity
The dynamic purpose of control, double-way check valve is used to implement manually braking and the switching of automatically controlled automatic braking selects, due to automobile chassis
Space it is limited, then mean to need to connect using tracheae between each several part using split type scheme, i.e., to occupy more
Space, while split type scheme processing cost also can be higher than integrated structure；In addition, ASR valves only possess boosting and decompression work(
Can, without pressure holding function, and AEBS systems with ESC system when braking, it is necessary to export according to a specific ratio, at this moment ASR valves are just
The functional requirement of ratio output cannot be met, in addition, for existing double-way check valve currently on the market+have the function of switch valve
Common electrically-controlled valve, no relay valve function, since air inlet/outlet is to directly control, the latus rectum of gas circuit is smaller, it is possible to provide gas
Measure it is limited, during for needing to enable emergency braking function, it is easy to cause brake force insufficient.
