Background technology
Existing automobile, the especially brake system of large-sized diesel automobile are mainly used following a few class: main brake, give wheel brake activation power, the braking force maximum that can provide by brake facing; The retarder braking by realizing braking for transmission system brake activation power with the form of fluid power or current vortex, except brake action, can also store braking energy get off; Energy brake by closing the exhaust valve of diesel engine, is given driving engine brake activation power, and is simple in structure, but the power that applies is less.At present full size vehicle is in braking procedure, more than three kinds of brake system work alone.With the energy brake is example, glancing impact, chaufeur is made judgement and is controlled the work that corresponding button starts exhaust and brake system according to running environment, will have following problem like this: (1) is owing to auxiliary braking systems such as energy brake, retarder braking usually uses in the road conditions complex environment, chaufeur is in spiritual high-pressure state usually in this environment, may cause forgetting the startup auxiliary braking system, cause the wasting of resources, can be accidents caused when serious; (2) auxiliary braking, especially energy brake is influential to the driving engine operation, if therefore in implementation process, strengthen engine throttle or change-speed box is carried out gear shift, driving engine may stop working, the air pump of the so not only purpose of out of reach car retardation, and service brake energy supply and provide the power steerig pump of power can not work by driving engine because of engine off, the safety of influence driving.(3) auxiliary braking exerts an influence to the service braking system brakig force distribution after starting, the insensitivity of harm Vehicular system.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of large-sized vehicle intelligent synthetic brake control system is provided.
The objective of the invention is to be achieved through the following technical solutions, it comprises accelerator pedal sensor, brake pedal sensor, engine speed sensor, car speed sensor, brake-pressure sensor, the energy brake control subsystem, retarder control subsystem and main brake control subsystem, it is characterized in that: described energy brake control subsystem, described retarder control subsystem and described main brake control subsystem link to each other with embedded middle control computer by bus, described accelerator pedal sensor, described brake pedal sensor, described engine speed sensor, described car speed sensor, described brake-pressure sensor also respectively with embedded in control computer link to each other, be used to calculate the startup opportunity of above-mentioned each subsystem and the intelligent comprehensive control policy storehouse of rate of braking described being provided with in the control computer in embedded.
The signal that the present invention gathers by each sensor is transferred to middle control computer with it, and calculates by the intelligent strategy storehouse, to realize the opportunity that each subsystem starts and the optimization of intensity.Thereby overcome the defective that exists in the prior art.
