Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the present invention is just to provide a kind of method that automotive hydraulic brake system realizes Electric automatic control, effectively can solve the electron steering problem of automotive hydraulic brake system.
The technical scheme that the present invention solves is, on the basis of existing automotive hydraulic brake system, the one-way hydraulic pump of charged control interface is used to be serially connected between master brake cylinder and the hydraulic tubing of brake cylinder, that is, vehicle one-way hydraulic series connection of pumps with ABS system is between master brake cylinder and ABS system, pump pressure direction be master brake cylinder to brake cylinder, thus realize the electron steering of automotive hydraulic brake system.
The inventive method is simple, easily existing vehicle is transformed, hydraulic braking system for automobile is made to realize electric control braking, and whenever can not affect deceleration and stopping performance and the manual operation of original system, have huge facilitation for the active safety product of automobile and the development of intelligent vehicle, social benefit is huge.
Accompanying drawing explanation
Fig. 1 is the frame diagram of present system.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
The present invention is in concrete enforcement, as shown in Figure 1, first electronic control system is installed, this system is serially connected between master brake cylinder and the hydraulic tubing of brake cylinder by existing hydraulic control system by the one-way hydraulic pump of band electrical interface, be about to the vehicle one-way hydraulic series connection of pumps of band ABS system between master brake cylinder and ABS system, pump pressure direction is that master brake cylinder is to brake cylinder, structure is, vacuum booster 1 is provided with brake pedal 10, vacuum booster is connected with master brake cylinder 3, the fluid reservoir 2 be communicated with pipeline between vacuum booster 1 with master brake cylinder 3 is equipped with, master brake cylinder 3 through pipeline respectively with the first one-way hydraulic pump 4a, second one-way hydraulic pump 4b, first one-way hydraulic pump 4a, second one-way hydraulic pump 4b is connected with automatically controlled interface 6 by wire, first one-way hydraulic pump 4a, second one-way hydraulic pump 4b is connected with ABS system (anti-skid brake system) 5 respectively, ABS system 5 respectively with the first brake cylinder 9a be contained on the near front wheel drg 8a, the second brake cylinder 9b on off front wheel drg 8b, the 3rd brake cylinder 9c on left rear wheel drg 8c, the 4th brake cylinder 9d on off hind wheel drg 8d is connected, after equipment installs, again automatically controlled interface is connected with electronic brake controller 7, the power signal of braking is sent to one-way hydraulic pump by electronic brake controller 7, the hydraulic pressure that hydraulic pump works twitches master brake cylinder pressurizes to brake cylinder direction, brake cylinder makes drg realize each wheel braking,
During vehicle braking force release, electronic brake controller 7 controls one-way hydraulic pump and quits work, between one-way hydraulic pump and car side brake, the hydraulic pressure of pipeline can discharge from trend master brake cylinder direction, after the fluid pressure of one-way hydraulic pump both sides hydraulic tubing reaches balance, brake system gets back to unclamped initial condition;
When through brake pedal, vacuum booster manual braking, act on master brake cylinder, no matter whether one-way hydraulic pump works, the pressure that manual braking acts on master brake cylinder generation can be delivered to each wheel generation braking force by conduit under fluid pressure, thus realize automotive hydraulic brake system Electric automatic control, the whenever not deceleration and stopping performance of influential system and manual operations.
Described drg is the one of brake disc, brake clamp or brake wheel;
Described ABS system also can be described as the abs pump with ABS system.
Be noted that, the each parts used in the present invention are prior art (commercially available prod), the contribution of the inventive method is these parts to combine through science, make the automotive hydraulic brake system of the Electric automatic control with novelty, realize transforming the Electric automatic control of existing motor vehicle braking systems, be effective to the control for brake of power actuated vehicle, ensure easy to use, traffic safety.
From the above, the present invention is the innovation to existing automotive hydraulic brake system, is namely with the hydraulic brake system of ABS system to be installed on the pipeline between master brake cylinder and ABS system by the one-way hydraulic pump with automatically controlled interface.One-way hydraulic pump with automatically controlled interface is directly installed on the hydraulic tubing between master brake cylinder and brake cylinder by the hydraulic brake system not with ABS system, realizes the reformation of electric control to former motor vehicle braking systems.
Electronic brake controller uses signal wire (SW) to be connected with one-way hydraulic pump of the present invention, when vehicle needs to brake, deceleration of electrons control convenience sends to one-way hydraulic pump by needing the braking force electric signal of braking, hydraulic pump works twitches the hydraulic pressure of master brake cylinder to the pressurization of brake cylinder direction, and brake cylinder makes drg realize each wheel braking.
