Description
Technical field
The present invention relates to a kind of field of vehicle control, more particularly to a kind of whole-control system, it is particularly applicable to optimize whole
Car controls, and improves the adaptation ability of engine, reduces adaptation cost.
Background technology
Core control part of the engine controller as whole automobile dynamic system, it gathers accelerator pedal signal, system
Dynamic pedal signal, speed change box clutch signal, neutral position switch signal and other various switches and sensor signal, and make corresponding
After judgement, control various peripheral hardware electric components to be operated or control is sent to other dynamical system control units by CAN
System order.With the increasingly raising of the requirements such as vehicle dynamic quality, security, application of the electronic product on automobile is also increasingly
It is more.
Existing engine controller uses international top-brand supplier more, because engine controller is by monopolization producer of foreign countries
Effect of Technique Barriers, automaker need match vehicle by the existing control strategy of engine controller manufacturer completely
Its engine, i.e., when same vehicle uses different engines, to meet the different requirements of the installation of the engine controller, vapour
Car manufacturer need to carry out adaptive improvement to existing design and program, be propped up when matching other controllers of all kinds
The development cost paid are expensive and the construction cycle is longer.Secondly, it is limited by engine controller itself Peripheral Interface and Installed System Memory
Influence, for some big data quantity information storage with record there is also certain limitation.
China Patent Publication No. is CN201141324Y, and publication date discloses for the utility model patent on October 29th, 2008
A kind of external throttle controller of electric-controlled engine, including system control module, knob adjustment module, A/D modular converters, D/A
Modular converter, display module and alarm module.System control module driving display module shows the rotating speed of engine, and to through A/
Vehicle transport condition signal after D modular converter analog-to-digital conversions is analyzed and judged, if vehicle is in the state of traveling,
Throttle control is set to stop the control to engine throttle;If vehicle remains static, to D/A modular converters output with
The proportional throttle voltage signal of knob Regulate signal.Although the utility model can make by starting controller to control engine,
But it still suffers from following defect：
1st, the utility model is to realize the function of its engine controller, and engine controller needs to access big quantity sensor and held
Row device, cause engine controller adaptation difficult.
2nd, the utility model is influenceed by engine controller itself Peripheral Interface and Installed System Memory are limited, big for some
There is also certain limitation with record for the storage of data amount information.
The content of the invention
The purpose of the present invention is to overcome the problem of installation matching is difficult present in prior art, there is provided one kind is easy to match
The whole-control system of engine controller.
To realize object above, technical solution of the invention is：
A kind of whole-control system, including entire car controller and engine, the entire car controller pass through CAN and engine
On engine controller be connected；
The entire car controller is opened with clutch switch, gearbox height gear switch, the gear switch of gearbox half, auxiliary braking respectively
Pass, neutral position switch, park brake switch, service brake switch are connected with the signal output part of accelerator pedal sensor；
The entire car controller is sent by CAN to engine controller to be started engine, closes engine, controls and start
Machine rotating speed or the instruction for controlling engine torque.
The entire car controller protects magnetic valve, exhaust braking electromagnetic valve, Brake lamp relay and electricity with gearbox respectively
The control terminal of sub- fuel pump is connected.
The entire car controller is connected with the signal output part of cruise control switch, when cruise control switch is opened,
Entire car controller sends the instruction of constant speed drive by CAN to engine controller.
The entire car controller is connected with the signal output part of air-conditioning request switch.
The signal output part that the entire car controller switchs with power taking is connected.
Compared with prior art, beneficial effects of the present invention are：
1st, the function of engine controller has been integrated into entire car controller in a kind of whole-control system of the present invention, vehicle control
Device processed switchs according to the clutch switch, gearbox height gear switch, the gear switch of gearbox half, the auxiliary braking that receive, neutral
Switch, park brake switch, the signal of service brake switch and accelerator pedal sensor send instruction, root to engine controller
According to unlatching, closing, moment of torsion and the rotating speed of instructing engine controller control engine, such design makes engine controller only
Power supply and CAN and a small amount of rigid line need to be accessed, substantially reduce the number the sensor and actuator quantity of engine controller access,
Because sensor and actuator that the engine controller of different model is adapted to it have different mounting adaptation requirements, automobile
Manufacturer needs to spend substantial amounts of R＆D fund to be adapted to different engine controllers, and the design controls original engine
The sensor and actuator of device connection are linked on entire car controller, avoid sensor and actuator and engine controller
The problem of not being adapted to, engine controller is set to turn into the actuator of entire car controller, the adaptation for reducing engine controller will
Ask, improve the design independence of automaker, reduce adaptation R＆D costs.Therefore, the design utilizes entire car controller
Engine controller is controlled, reduces the adaptation requirement of engine controller, improves the design independence of automaker.
2nd, entire car controller is carried out at signal according to the sensor signal received in a kind of whole-control system of the present invention
The backward each actuator of reason sends instruction control, and it is acted, in other electric-control systems of all kinds of vehicle match, entire car controller
The unified match management for being responsible for various hardwire interfaces and bus protocol, and management to the network information in CAN, scheduling, divide
Analysis and computing, not only reduce the development amount of engine controller during system matches, and the control strategy of engine
Grasped by automaker, automaker is had the initiative in hands, additionally it is possible to improved the control strategy of vehicle on the whole, keep away
The situation that available engine control strategy and integrated vehicle control tactics clash is exempted from.Therefore, the control of the design engine by
Entire car controller is completed, effectively perfect integrated vehicle control tactics.
