The specific embodiment:
As shown in Figure 1, the utility model comprises set brake facing 11 on electronic control unit 2 and the wheel hub, it is characterized in that: described electronic control unit 2 links with brake facing 11 by a dynamo-electric brake 1, can drive brake facing 11 by dynamo-electric brake 1 and make longitudinal travel, make it to control the rotation of wheel, to produce braking effect.On wheel and chaufeur brake pedal, also be respectively equipped with wheel speed sensors 4 and brake pedal sensor 5, be electrically connected with electronic control unit 2, electronic control unit 2 can receive parking brake signals 6, wheel velocity signal and the braking dynamics signal that sends from chaufeur on brake pedal, through handling, dynamo-electric brake 1 is sent control command, drive each mechanism action, finish braking procedure.
Fig. 2 has showed the embodiment of the utility model dynamo-electric brake 1.As shown in the figure, described dynamo-electric brake 1 comprises motor 16, but this motor 16 is the pulsed buncher of the forward and backward of certain power, join with electronic control unit 2, send control signal by it, motor 16 is rotated or stop, motor 16 output shafts link to each other with tumbler on the engagement component, the tumbler of present embodiment is a gear 17, also can be worm gear or other tumblers, the moving member that joins with tumbler is a tooth bar 15, also can be worm screw or other moving members, the rotation of motor 16 can be converted into the mobile form of moving member by the effect of engagement component.At tooth bar 15 1 ends, be connected with push rod 18, both can make an integral body, push rod 18 1 ends place in the main body 14, and this main body 14 is provided with a cavity, is provided with piston 12 in it, these piston 12 1 ends and brake facing 11 join, the other end connects elastic component, and the elastic component of present embodiment is a spring 13, also can be other elastic components.Described spring 13 1 ends and piston 12 end faces join, and the other end links to each other with baffle plate 18.Spring 13 can play the effect of buffering, and absorption portion produces bigger vibration by the antagonistic force of 11 pairs of push rods 18 of brake facing to avoid glancing impact.In the time of on chaufeur is entered into brake pedal, can send speed-slackening signal 6, brake pedal sensor 5 is sensed the dynamics of chaufeur glancing impact simultaneously, send signal also for electronic control unit 2, electronic control unit 2 is accepted behind this signal through handling, dynamo-electric brake 1 is sent instruction, motor 16 on it output speed under the control of electronic control unit 2, motor 16 rotates, driven gear 17 or worm gear rotate, and tooth bar 15 that is meshed with gear 17 or worm gear or worm screw are converted to very brief rotating speed rapidly the linear displacement of push rod 18; Push rod 18 linear displacements will affact on the harder spring 13 with certain speed, and spring 13 is very fast to be used masterpiece on the piston 12, promote brake facing 11 displacements.When brake facing 11 reach was close on the wheel hub, owing to be pressed together and form lock torque, be pressurized state this moment with the wheel hub of wheel revolutions and the brake facing 11 that can not rotate.When electronic control unit 2 is accepted wheel speed sensors 4 signals and is required lock torque to be in when constant as calculated, Locking Device action this moment, lock torque remains unchanged, and system forms packing state.When electronic control unit 2 is accepted wheel speed sensors 4 signals and require lock torque to reduce as calculated, motor 16 is sent the counter-rotating instruction, drive push rod 18 by joggle piece and do reverse displacement, piston 12 moves backward, brake facing 11 leaves wheel hub, and lock torque reduces, and system forms decompression state.
But said process adopts the pulsed buncher of the forward and backward of certain power repeatedly, and it is output speed under the control of ECU, and the pressurization of ABS, pressurize, decompression correspond to just commentaries on classics, locking, the counter-rotating action of motor.
The utility model all is equipped with dynamo-electric brake 1 and wheel speed sensors on each wheel, electronic control unit 2 is by detecting each wheel wheel speed signal and chaufeur braking maneuver strength signal, by the ABS control logic, work alone through calculating, judge back each dynamo-electric brake 1 of commander.
The utility model electronic control unit 2 working processs:
As shown in Figure 3, behind automotive ignition, electronic control unit 2 is in power-up state, and carries out the self check of ABS function simultaneously, if during unusual circumstance, warning circuit can send alerting signal, and enters and do not have the normal brake application of ABS function program.If self check is normal, then calculate the vehicle acceleration of glancing impact by electronic control unit 2, enter normal brake application program or abs braking program with decision.
Electronic control unit 2 relates generally to software control part, and its design should have following radical function:
1) adaptation function: in the abs braking process, the various different ground-surface adhesion valuies that can discern automobile automatically and travelled, thus take corresponding control strategies.
2) predictive control and closed loop tuning function: in the abs braking process, can calculate the wheel slip of various different operating modes fast, and form the closed loop tuning, make wheel slip fall within best stabilized zone.Controlled variable is a wheel slip, and the control index is about slip rate=20%.
3) logic control function: ABS software only works when emergency braking (speed of a motor vehicle is greater than 15 kilometers/hour), and does not influence the brake action of conventional brake system under other situations.
4) controllable function is selected in safety: when two trailing wheel brake imbalances of automobile or institute's track left and right sides adhesion value not simultaneously, software can be discerned the wherein bigger wheel of danger coefficient automatically, thereby selects it as the major control object, guarantees the car load safety.
5) anti-interference function: software can be got rid of the interference of various factors such as vehicle behavior, road, weather, by measures such as filtering, compensation, makes the software stable operation.
6) selfdiagnosis defencive function: various faults and warnings such as software energy automatic identification sensor, control cock, controller, safety is enabled normal brake system simultaneously.
The utility model can be selected the operating mode of hand brake or foot-propelled braking.The advantage of hand brake is to change two of traditional pin pipes---the operating habit of throttle and braking door, avoid stepping on wrong function pedal, and cause artificial safety misadventure.The foot-propelled braking is traditional operating mode, can assemble a kind of pedal stroke and rate of braking stretcher one to one.No matter adopt which kind of brake control mode, all brake pedal sensor 5 need be installed, to measure braking maneuver intensity, convert the application force that be transported on the wheel to by electronic control unit 2 decisions then.
