Abstract
The utility model discloses an automobile vacuum power-assisting system, which comprises a vacuum power-assisting device and a whole automobile controller, wherein a vacuum pressure sensor is arranged on a front casing of the vacuum power-assisting device, and the vacuum pressure sensor is electrically connected with the whole automobile controller. Because of the adoption of the structure, the utility model has the following advantages that 1. the vacuum degree of the vacuum power-assisting device can be detected in real time, and the stability of the vacuum degree can be controlled according to actual conditions; 2. the stability of the vacuum degree of the vacuum power-assisting device is maintained, so the stability of the power-assisting effect of the system can be ensured, and the comfort of the pedal can be finally ensured; and 3. the structure is simple, and the effect is good.
Description
Technical field
The utility model relates to automobile technical field, particularly a kind of vacuum automobile force aid system.
Background technology
The power-assisted effect of automobile vacuum booster is relevant with the degree of vacuum of servo-unit, and when the degree of vacuum of servo-unit reduced, the power-assisted effect also reduced, the non-constant of power-assisted effect, and treadle effort increases the weight of, and the sensation during the chaufeur pedal can non-constant.And existing vacuum servo system can't detect the degree of vacuum of servo-unit in real time, and the stability of more uncontrollable degree of vacuum causes power-assisted effect instability, influences the traveling comfort of pedal.
The utility model content
Technical problem to be solved in the utility model is at the deficiencies in the prior art, to provide a kind of and can detect the degree of vacuum of vacuum booster in real time, and control the vacuum automobile force aid system of its vacustat.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum automobile force aid system, comprise vacuum booster and entire car controller, the front case of described vacuum booster is provided with vacuum pressure sensor, and described vacuum pressure sensor is electrically connected with described entire car controller.
The front case of described vacuum booster is provided with mounting hole, and described vacuum pressure sensor is sealedly connected in the described mounting hole by a seal ring.
Described entire car controller is connected with performance element, and described vacuum pressure sensor is transferred to entire car controller with the signal of gathering, entire car controller with signal conditioning after control execution unit.
Described performance element comprises driving engine and vacuum pump.
The utility model adopts said structure, has the following advantages: 1, can detect the degree of vacuum of vacuum booster in real time, and control the stability of degree of vacuum according to actual conditions; 2, keep the stability of the degree of vacuum of vacuum booster, thereby guaranteed the power-assisted effect stability of this system, finally guaranteed the traveling comfort of pedal; 3, simple in structure, respond well.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail;
Fig. 1 is the structural representation of vacuum booster in the utility model;
Fig. 2 is a functional block diagram of the present utility model;
In Fig. 1～Fig. 2,1, vacuum booster; 2, entire car controller; 3, vacuum pressure sensor; 4, performance element.
The specific embodiment
As Fig. 1～a kind of vacuum automobile force aid system shown in Figure 2, comprise vacuum booster 1 and entire car controller 2, the front case of vacuum booster 1 is provided with vacuum pressure sensor 3, and vacuum pressure sensor 3 is electrically connected with entire car controller 2.The front case of vacuum booster 1 is provided with mounting hole, and vacuum pressure sensor 3 is sealedly connected in the mounting hole by a seal ring.Entire car controller 2 is connected with performance element 4.Vacuum pressure sensor 3 can be gathered the degree of vacuum signal of vacuum booster 1 ante-chamber in real time, and the signal of gathering is transferred to entire car controller 2, and entire car controller 2 is with control execution unit after the signal conditioning 4.Performance element 4 comprises driving engine and vacuum pump.When the degree of vacuum of vacuum servo-unit 1 is hanged down, for example engine speed is lower or driving engine stops operating, or automotive operation is in the area of rarefaction of air, vacuum pressure sensor 3 collects the less signal of degree of vacuum and gives entire car controller 2, entire car controller 2 will control execution unit 4 increase degree of vacuum, realizes by increasing engine speed or starting vacuum pump; When degree of vacuum increased to force aid system and can keep preferably the power-assisted effect, entire car controller 2 can control execution unit 4 stop to continue to increase degree of vacuum, realized by the running that reduces engine speed or stop vacuum pump.This system is by detecting the degree of vacuum of vacuum booster 1 in real time like this, and the vacustat of control vacuum booster 1 guarantees vacuum-assisted effect stability, thereby guarantees the traveling comfort of pedal.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
