Description
Technical field
The present invention relates to a kind of auto electronic controller for vacuum pump.Specifically, it is exactly a kind of auto electronic vavuum pump control
Device, is consisted of：Directly affect vehicle braking electronic vacuum pump (EVP, Electronic vacuum pump) not by
Engine controller (ECU, Electronic Control Unit) etc. is controlled, but by being equipped with fortune with one-piece type
The single control module for calculating processing and control function is controlled.
Background technology
In general, the brake apparatus (Brake System) of vehicle is used to make vehicle deceleration or the stopping of traveling, carries
Brake booster (brake booster) on brake apparatus makes driver trample brake pedal as one kind in abrupt deceleration vehicle
Legpower multiplication (Boosting) device, can substantially be divided into vacuum type booster and fluid pressure type booster and electrodynamic type power-assisted
Device.
For for operating the hydraulic pressure that brake pedal is produced to make the hydraulic brake that vehicle is braked as medium, producing liquid
The master cylinder (master cylinder) of pressure is using the strength operating applied from booster (Booster), and wherein booster is with driver
The amount of the treading in change of the brake pedal of operation and the pressure differential that is formed between atmospheric pressure and vacuum, this booster is in order to will braking
Pedal manipulation force amplifies and is provided to master cylinder and formula structure is integrally formed with the generator (Generator) driven by engine,
Or constitute pump type (MVP, Mechanical Vacuum using the mechanical vacuum pump being connected with the lid axle of engine air admittance manifold
Pump) structure.But, for spark ignition passenger car, the mode using negative pressure is mainly taken, the negative pressure is piston in engine air admittance
Produced when being moved back and forth in manifold.This is compared with the pump type structure using mechanical vacuum pump, and its load is smaller, without
Separately attachment sets expensive mechanical pump, it can be said that being a kind of very economical method.
In order to ensure by the manipulation force of brake pedal drive and internally formed while operate atmospheric pressure and vacuum it
Between pressure differential, the brake booster use plunger valve (Plunger Valve) and poppet (Poppet Valve), work as post
Plug valve is axially moveable in the presence of brake pedal to be made to be formed in valve body after relative distance difference, by being produced by relative distance difference
Space and the atmospheric pressure that flows into will be with being vacuum formed pressure differential and promoting dividing plate (Diaphragm), so that in pedal force
On the basis of along with atmospheric pressure formation multiplication strength operate master cylinder.
In addition, in order to use electronic vacuum pump the problem of solving that vacuum can not be formed in vacuum brake assistor.For
Electronic vacuum pump is controlled, the micro-control module and vacuum transducer and vacuum such as engine controller must be just used
Switch.
Wherein, for the brakes using vacuum transducer, it enters the result that vacuum transducer continuously senses
Row compares and transmitted to the controller with computing circuit, controlling value after processing be used to being controlled electronic vacuum pump after
Operating of electrical equipment (relay) etc..In this case, just it must be provided with comprising separately controller or the hardware of control algolithm.Just
For hardware, due to it be by engine controller control, therefore, when engine controller occur it is damaged and more than using the longevity
Situations such as life and when occurring maloperation, vacuum cannot be formed in booster by electronic vacuum pump.
In general, electronic vacuum pump is mainly used in making up vacuum not enough in booster, to ensure that driver can lead to
The pressure for crossing abundance is braked to vehicle.As noted previously, as electronic vacuum pump is controlled by engine controller,
Therefore when maloperation occurs for engine controller, in some instances it may even be possible to influence whether brakes, it is impossible in the wink needed for driver
Between form vacuum so that can not to vehicle implement brake.Thus, because that can not brake caused by Accident of Large-scale can also seize driving
The life and property of people.
The engine controller (ECU) is usually entered by the way of traction (pulling) or cut-out (interrupt)
Row control.In the controller that the execution complex calculation of such as engine controller is handled, if using mode of traction, controller
Substantial amounts of resource (Source) is taken, other computings are thus influenced whether；If, can be than existing place using cut-out mode
The preferential operating of reason order, so as to influence the stability of wagon control.
In addition, when the vacuum-control(led) system of engine controller occur it is abnormal need to change when, what is existed unreasonable is in
In, it is necessary to by engine controller integral replacing.
Accordingly, it would be desirable to a kind of independent controller is developed, even if to ensure not to be controlled by engine controller,
Separately electronic vacuum pump can also be controlled.
In addition, the first technology related to motor vehicle braking system includes No. 10-1257213 (name of invention of registered patent
Claim：Vehicle braking safety device) and No. 10-2013-0026951 (title of invention of publication：Vavuum pump integrated-type is travelled
Security control device).
