Description
Technical field
The novel electronlmobil braking technology field that relates to of the present invention, the electronic auxiliary braking system of particularly a kind of electronlmobil.
Background technology
Servo-unit is the relevant apparatus of vehicle by pressurized air, high pressure wet goods operating and controlling vehicle, uses light purpose to reach, and in brake system of car, is used to alleviate the working strength of chaufeur.Servo-unit is installed between brake pedal and the master brake cylinder, servo-unit is divided into vacuum booster and hydraulic booster, the negative pressure that vacuum booster produces when being the dependence engine charge is as propulsion source, the front/back cavity draught head of vacuum booster is increased, thereby the power that makes the force rate chaufeur that affacts on the master brake cylinder step brake pedal greatly increases, and reaches vacuum-assisted purpose.Because the negative pressure that driving engine provides is lower, vacuum booster vacuum power deficiency causes the power that is loaded on the master brake cylinder not enough, causes the braking force deficiency, and the stopping distance of automobile is long like this, easily has an accident the vehicle safety performance deficiency.
Summary of the invention
The later-model purpose of the present invention is to provide a kind of electronic auxiliary braking system of electronlmobil that is used for electronlmobil, it can provide sufficient braking force for electronlmobil, improved the deceleration and stopping performance of electronlmobil, thereby improved the safety performance of electronlmobil, overcome the defective that prior art exists.
The technical scheme that novel its technical matters of solution of the present invention is adopted is: the electronic auxiliary braking system of a kind of electronlmobil, comprise master brake cylinder, brake pedal, vacuum booster, vacuum pump and vacuum servo controller, vacuum booster is connected with master brake cylinder with brake pedal respectively, be provided with vacuum reservoir between described vacuum booster and the vacuum pump, vacuum booster is connected by vacuum line with vacuum reservoir, vacuum reservoir is connected by vacuum line with vacuum pump, the vacuum line that connects vacuum booster and vacuum reservoir is provided with vacuum check valve, vacuum reservoir is provided with the vacuum-pressure detection device, and the vacuum-pressure detection device is connected with the vacuum servo controller respectively with vacuum pump.Vacuum pump can be controlled the size of degree of vacuum in the vacuum reservoir, vacuum reservoir provides vacuum source by vacuum line to vacuum booster, the vacuum-pressure detection device can detect the degree of vacuum of vacuum reservoir, when the pneumatics force checking device of taking seriously detects the vacuum degree deficiency of vacuum reservoir, the vacuum servo controller is opened vacuum pump, thereby for vacuum booster provides enough degree of vacuum, when the degree of vacuum of vacuum reservoir is enough, the vacuum servo controller cuts out the operation of vacuum pump, energy-conservation like this, and can prolong service life of vacuum pump.
As preferably, be provided with barrier film in the described vacuum booster, barrier film is divided into ante-chamber and back cavity two parts with vacuum booster, and back cavity is provided with control cock, and described ante-chamber is communicated with vacuum reservoir, and described back cavity is connected with brake pedal by control cock.
