Detailed description of the invention
, refer to Figure of description below, the present invention is further described.
As shown in Figure 1, this EHB mainly comprises: brake pedal 1, push rod 2, piston 1, electromagnetic valve 1, electromagnetic valve 25, pull back spring 1, pedal sense simulation cylinder cylinder body 7, fluid reservoir 8, electronic control unit 9, electromagnetic valve 3 10, pull back spring 2 11, master brake cylinder 12, motor 13, piston 2 14, helical speed reduction gear structure 15, pedal force sensor 16, pedal displacement sensor 17, hydraulic coupling sensor 18, brake wheel cylinder 19.
Brake pedal 1 is connected to piston 1 by push rod 2, piston 1 contacts with pull back spring 1, piston 1 and pull back spring 1 are installed in simulates cylinder cylinder body 7 inside at pedal sense, pedal force sensor 16 and pedal displacement sensor 17 are installed on brake pedal 1, fluid reservoir 8 is connected to pedal sense by electromagnetic valve 1 and brake piping and simulates cylinder cylinder body 7, pedal sense simulation cylinder cylinder body 7 is connected to brake wheel cylinder 19 by electromagnetic valve 25 and brake piping, hydraulic coupling sensor 18 is arranged on brake piping, the turning cylinder of motor 13 is connected to helical speed reduction gear structure 15, olinear motion part in helical speed reduction gear structure 15 contacts with piston 2 14, it is inner that piston 2 14 and pull back spring 2 11 are installed in master brake cylinder 12, master brake cylinder 12 is connected to brake wheel cylinder 19 by electromagnetic valve 3 10 and brake piping, above-mentioned each electromagnetic valve and sensor are all connected to electronic control unit 9 by wire.
In this exemplary embodiment, pedal sense simulation cylinder comprises the parts such as pedal sense simulation cylinder cylinder body 7, piston 1 and push rod 2.
During normal work, brake system controller detects that system is normal, and system then can open electromagnetic valve 3 10 enables liquid in master brake cylinder 12 pass through.After chaufeur steps on brake pedal, displacement pickup 17 obtains speed when brake pedal is stepped on and displacement, signal is transferred to brake system controller (being electronic control unit 9) by signal wire (SW), brake system controller analytic signal the master cylinder thrust calculated corresponding to the braking force desired by chaufeur
.Then, brake system controller sends instruction to motor 13, drives helical speed reduction gear structure 15 move and drive master cylinder piston 2 14, thus realizes the function of building pressure, and liquid is by flowing into each brake wheel cylinder 19 after electromagnetic valve 3 10 thus realizing braking function.After chaufeur stops braking maneuver, after the data of brake system controller received bit displacement sensor 17, instruction can be sent to motor 13 by analytical Calculation, control motor movement and reduce hydraulic coupling in master brake cylinder 12, thus reduce hydraulic coupling in each brake wheel cylinder 19, by vehicle brake off state, and piston 2 14 return under pull back spring 2 11 acts on, for braking preparation next time.
Meanwhile, in order to make brake pedal 1 of the present invention provide brake pedal feel when trampling to chaufeur, be equipped with pedal sense simulation cylinder 7, electromagnetic valve 1 and electromagnetic valve 25.Electromagnetic valve can need continuous switch to regulate pedal to simulate in-cylinder pressure according to pedal sense, thus simulation pedal reaction force, ensure pedal sense.When chaufeur push down on the pedal 1, brake system controller is obtaining the master cylinder thrust corresponding to the braking force desired by chaufeur
while, obtain the treadle effort signal of target according to pedal force sensor 16 signal, electronic control unit 9 by hydraulic coupling in the regulable control pedal sense simulation cylinder cylinder body 7 of electromagnetic valve 1 and electromagnetic valve 25, produces target pedal reaction force based on this signal.When the systems are operating normally, if when pedal feedback force needs to increase, open electromagnetic valve 25, closed electrical magnet valve 1, now master brake cylinder 12 liquid can enter pedal sense simulation cylinder thus simulation in-cylinder pressure is raised.When pedal feedback force needs to reduce, open electromagnetic valve 1, closed electrical magnet valve 25, in now pedal sense simulation cylinder, liquid can flow into fluid reservoir 8, thus simulation in-cylinder pressure is reduced.After chaufeur stops braking maneuver, pull back spring 1 can promote piston 1, push rod 2, brake pedal 1 return.
Consider that automatically controlled Linear Moving Module lost efficacy.Brake system controller will make electromagnetic valve 1 close, electromagnetic valve 25 is opened, electromagnetic valve 3 10 is closed, now chaufeur foot pedal still can be simulated in cylinder at pedal sense and be produced certain pressure, and liquid can flow to brake piping by electromagnetic valve 25, even if the braking force still produced by pedal sense simulation cylinder when automatically controlled Linear Moving Module lost efficacy like this realizes brake efficiency.
Consider pedal sense simulation cylinder and be attached thereto pipeline to lose efficacy, if hydraulic coupling sensor 18 detects that described pipeline lost efficacy, by Signal transmissions to electronic control unit 9, electronic control unit 9 can control shut electromagnetic valve 25.Thus braking procedure can lose the simulation of pedal sense, now chaufeur foot pedal can make motor pushing master brake cylinder, still can realize brake efficiency.
Another kind of failure conditions, if system dead electricity, because electromagnetic valve 1, electromagnetic valve 3 10 are normally closed valve, electromagnetic valve 25 is normally open valve, so electromagnetic valve 1, electromagnetic valve 3 10 still can be made to close, electromagnetic valve 25 is opened, now chaufeur foot pedal still can be simulated in cylinder at pedal sense and be produced certain pressure, and liquid can flow to brake piping by electromagnetic valve 25, even if the braking force still produced by pedal sense simulation cylinder when automatically controlled Linear Moving Module lost efficacy like this realizes brake efficiency.
For a person skilled in the art, other advantages of the present invention and substituting embodiment are apparent.Therefore, the present invention is not limited to shown and described detail, representative configurations and exemplary embodiment with regard to its more wide in range meaning.On the contrary, those skilled in the art can carry out various amendment and substitute when not departing from essence spirit of the present invention and scope.
