Abstract
The invention relates to a vehicle electronic control machine braking system which comprises four parts, namely a pedal simulator, a braking system controller, a power drive circuit and a machine execution mechanism. Accordingly, the anti-interference performance of the vehicle electronic control machine braking system is enhanced under the environment of complex work conditions of vehicles and under the environment of an external exposed electromagnetic field and an earth magnetic field.
Description
Technical field
The present invention relates to a kind of vehicle electrically controlling mechanical braking sytem.
Background technology
The braking ability of automobile refers to and can in short range, stop in motion and maintain travel direction stability and when lower long slope, can maintain the ability of certain speed of a motor vehicle.Existing electrical brake system adopts a large amount of electronic control technologies to be just difficult to the electronic circuit of avoiding a large amount of, and because vehicle working condition is complicated and work in the electromagnetic field of outer exposed and earth magnetic field environment, this just need to strengthen the antijamming capability of electrical brake system again.Meanwhile, owing to having adopted a large amount of sensors, control chip and new technology, make the cost of current electrical brake system higher than existing hydraulic brake system cost, the use cost that therefore reduces system is also the current problem that needs solution.
Summary of the invention
In order to overcome the technical matters of above-mentioned brake system, the invention provides a kind of vehicle electrically controlling mechanical braking sytem.
The technical scheme that the present invention adopted is for achieving the above object: vehicle electrically controlling mechanical braking sytem comprises four parts, that is: pedal simulator, brake system controller, power driving circuit, mechanical actuating mechanism.The power that pedal simulator tramples chaufeur on brake pedal is converted into speed-slackening signal and passes to brake system controller, completes braking procedure, and certain chaufeur that feeds back to is provided by brake system controller control mechanical actuating mechanism.Brake system controller is accepted the signal of each sensor, according to certain algorithm, braking motor is controlled, and is provided feedback signal to pedal simulator.Power driving circuit, for motor provides electric current, is the interface that brake system controller is controlled motor.Mechanical actuating mechanism slows down and increases square brshless DC motor, and the moment loading producing is produced to lock torque to brake disc.
Accompanying drawing explanation
Fig. 1 is composition of the present invention and functional block diagram.
The specific embodiment
A specific embodiment of the present invention is as shown in Figure 1:
In vehicle traveling process, when running into emergency situation and need to brake, chaufeur is trampled brake pedal, and pedal simulator sends speed-slackening signal to brake system controller, and driving device actuating unit is started working and lock torque is provided.Vehicle wheel rotational speed and car speed feed back to brake system controller through speed sensor, and calculate the real-time slip rate of automobile, by the same expectation of the slip rate s of actual computation slip rate s
pcompare, its difference is controlled and is outputed to brshless DC motor rotary speed controling unit through PID, as brshless DC motor rotational speed setup signal.Motor speed regulating control carries out the given signal of computing generation current of electric regulating control to the difference of rotational speed setup signal and speed feedback signal, by the electric current that changes brshless DC motor, change output torque size, thereby reach, control the object of lock torque, the coefficient of road adhesion φ while making running car is always at the φ of φ-s curve
pnear variation.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
