Background technology
General claim that automobile is kept straight-line travelling in braking procedure or be the glancing impact road holding by the ability of predetermined negotiation of bends.Automobile sometimes because braking deviation, rear axle break away or front-wheel loses steering capability and make the automobile get out of hand leave original travel direction, even bangs into the other side's vehicle running rail, hyposulculus, slides the dangerous situation on hillside in braking procedure.The automobile brake sideslip is because does not wait in the brake strap and the brake wheel gap of the left and right wheel of same vehicle bridge; Compressed air brake cylinder push rod stroke difference is too big; There are greasy dirt, air chamber gas leakage, rupture of diaphragm in individual wheel brake shoe lining surface; Drums worn or turned until too thin, reasons such as individual wheel low tyre cause the wheel braking moment difference of same vehicle bridge and arranged on left and right sides to cause too greatly.For common chaufeur; Because do not understand the principle of braking deviation and the way of releasing; When emergency brake, in case the situation of braking deviation appears, and will be panic; This has just greatly increased the danger of driving, and makes braking deviation become one of major reason that causes traffic accident.
Though present ESP system has anti-deviation function; But because the expensive of ESP system; Be difficult on the low and middle-end car and popularize, therefore be badly in need of a kind of cheap control setup that prevents the automobile brake sideslip, popularization and application is on low and middle-grade cars; To help chaufeur to solve the phenomenon of braking deviation, improve running safety.
Summary of the invention
The objective of the invention is to propose a kind of cheap control setup that prevents the automobile brake sideslip and control method thereof, solve the phenomenon of braking deviation, improve running safety to help chaufeur.
The control setup of automobile brake sideslip that prevents of the present invention comprises control unit, brake pedal sensor, tachogen, brake-pressure regulation device, and the number of the corresponding automotive wheel of the number of said tachogen is to be used to detect the rotating speed of each wheel; The number of the corresponding automotive wheel of the number of said brake-pressure regulation device is to be used to control the braking force of each wheel, and said control unit links to each other with brake pedal sensor, each tachogen, each brake-pressure regulation device respectively.The brake-pressure regulation device that wherein is used for detecting the wheel speed sensors of each vehicle wheel rotational speed and is used to control each wheel braking force has been widely used in systems such as ABS, ESP, is the public to know, and repeats no more here.
Further, said control unit also is connected with alarm device, can when brake system breaks down, in time remind chaufeur to keep in repair like this.Alarm device can be made up of instrument, horn trumpet etc.
Further, said control unit is the car body controller of automobile, to make full use of the existing installation of automobile, reduces cost.
The step of the control method of the above-mentioned control setup that prevents the automobile brake sideslip is following: after said control unit receives the speed-slackening signal of brake pedal sensor transmission; Utilize tachogen to detect the rotating speed of each wheel; And control the output of each brake-pressure regulation device according to the rotating speed of each wheel; Thereby control the braking force of each wheel, regulate the rotating speed of wheel, make the rotating speed of each wheel reach unanimity.
Specifically; When the difference of mean speed that detects rotating speed and all wheels of certain wheel through tachogen when control unit surpasses predetermined value; Promptly report to the police through alarm device; Control output simultaneously, adjust the braking force of this wheel, make the rotating speed of this wheel trend towards the mean speed of all wheels corresponding to the brake-pressure regulation device of this wheel.
The above-mentioned control method of the control setup of automobile brake sideslip that prevents can also realize through detecting and control the fast pace of change of wheel; Its step is following: after said control unit receives the speed-slackening signal of brake pedal sensor transmission; Utilize tachogen to detect the rotation speed change speed of each wheel; And control the output of each brake-pressure regulation device according to the rotation speed change speed of each wheel; Thereby control the braking force of each wheel, regulate the rotating speed of wheel, make the rotation speed change speed of each wheel reach unanimity.
Specifically; When the difference of mean speed pace of change that detects rotation speed change speed and all wheels of certain wheel through tachogen when control unit surpasses predetermined value; Promptly report to the police through alarm device; Control output simultaneously, adjust the braking force of this wheel, make the rotation speed change speed of this wheel trend towards the mean speed pace of change of all wheels corresponding to the brake-pressure regulation device of this wheel.
Of the present inventionly prevent that the control setup of automobile brake sideslip is simple in structure, cost is low, is swift in response; Control is reliable; Can in time judge automobile and deviation phenomenon whether occur, and when sideslip takes place automatic compensation motoring condition and remind the driver, improved running safety.
Description of drawings
Fig. 1 is the schematic diagram that prevents the control setup of automobile brake sideslip of the present invention.
The specific embodiment
Contrast accompanying drawing below; Through the description to embodiment, the effect of mutual alignment between the shape of specific embodiments of the invention such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are done further to specify.
Embodiment 1:
As shown in Figure 1; The control setup that prevents the automobile brake sideslip of present embodiment comprises control unit, brake pedal sensor, tachogen, brake-pressure regulation device, the alarm device that car body controller constitutes, and wherein the number of the corresponding automotive wheel of the number of tachogen is to be used to detect the rotating speed of each wheel; The number of the corresponding automotive wheel of the number of brake-pressure regulation device is to be used to control the braking force of each wheel, and control unit links to each other with brake pedal sensor, each tachogen, each brake-pressure regulation device, alarm device respectively.
