The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing is described in further details content of the present invention and principle of work thereof.
Principle of work with reference to the air-pressure brake antilock system of Fig. 1,2 hybrid vehicles of the present invention is:
After mixed powered automobile started, braking anti-lock controller-ECU38 carried out initialization, and with the mutual transmit status confirmation message of entire car controller-HCU39.After message is confirmed correctly, braking anti-lock controller-ECU 38 just carries out condition monitoring to preceding left and right wheels 1,11 and back left and right wheels 36,26, in case find to have the braking incident to take place, promptly work as chaufeur and step on brake pedal 16, for front axle, the brake gas in the preceding air receiver 20 enters front-wheel left and right sides compressed air brake cylinder 3 by preceding triple valve 6, front-wheel left and right sides braking anti-lock electromagnetic valve 4 and 8 successively by brake activation valve 7 and 9 pairs of front-wheels are braked; For rear axle, the brake gas of back air receiver 22 enters relay valve 32 by brake activation valve 7, enters trailing wheel left and right sides compressed air brake cylinder 34 by two-way one-way valve 30, triple valve 31, trailing wheel left and right sides braking anti-lock electromagnetic valve 33 and 29 successively then and 27 pairs of trailing wheels are braked; Pressure sensor I 21 between brake activation valve 7 and relay valve 32 and the pressure sensor II 28 in trailing wheel left and right sides compressed air brake cylinder 34 or 27 give braking anti-lock controller 38 with force value separately respectively simultaneously.This moment, energy-recuperation system also participated in work, and braking anti-lock controller-ECU 38 is by left and right wheel speed sensors 2,10 of front-wheel and left and right wheel speed sensors 35, the 25 monitoring wheel front and back wheel states of trailing wheel.
If the left and right wheel 36,26 of preceding left and right wheel 1,11 and back does not reach the ABS control requirement, braking anti-lock controller-ECU38 does not participate in regulating the pressure of left and right compressed air brake cylinder 3,9 of front-wheel and the left and right compressed air brake cylinder 34,27 of trailing wheel, just monitor the state of wheel, this moment the energy recovery subsystem the induction motor utilization after left and right wheels 36,26 is counter drags generating, electric current flow back in the battery; Locking phenomenon takes place in case braking anti-lock controller-ECU38 finds to have in the wheel soon, at first send the work request message to entire car controller-HCU39, after entire car controller-HCU 39 confirms this message, make induction motor stop energy recovery, braking anti-lock controller-ECU38 controls brake drum of front wheel right hand and left hand simultaneously, right electromagnetic valve 4,8 and a trailing wheel left side, right electromagnetic valve 33,29 carry out pressure control, after the braking anti-lock end of braking, braking anti-lock controller-ECU38 sends to entire car controller-HCU 39 and withdraws from the control request message, obtain at braking anti-lock controller-ECU 38 recovering its monitor state behind the affirmation message of entire car controller-HCU 39, control is given entire car controller-HCU 39.
When vehicle is in braking energy recovery state, suddenly induction motor hinders inefficacy for some reason, at this moment by entire car controller-HCU39 the motor failure condition signal is issued braking anti-lock controller-ECU 38, braking anti-lock controller-ECU 38 enters motor inefficacy mode of operation, braking anti-lock controller-ECU 38 obtains the energy recovery message of motor inefficacy previous moment, braking anti-lock controller-ECU 38 is again according to pressure sensor I 21 then, the signal of pressure sensor II 28 carries out gas compensation calculating and 23 pairs of compressed air brake cylinders of control compensation control cock carry out the gas compensation, gas is directly by back air receiver 22, pressure compensation adjuster 23, two-way one-way valve 30, triple valve 31, a trailing wheel left side, right braking anti-lock electromagnetic valve 33,29 trailing wheel left sides, dextrad compressed air brake cylinder 34,27 make-up gas lost efficacy to a left side, back to reduce motor, right wheel 36,26 influences that cause.After the chaufeur braking requirement finished, braking anti-lock controller-ECU 38 closed pressure compensation adjuster 23.When not needing to compensate gas, pressure-compensation control valve 23 cuts out always, i.e. 23 work when induction motor lost efficacy of pressure-compensation control valve.
Fig. 3 and Fig. 4 are the simulation result of the present invention under MATLAB.From Fig. 3 and Fig. 4 as can be known, the present invention is not only reclaiming braking energy effectively, and reasonably co-operative control braking regeneration system and antiblock device, has prevented wheel lockup effectively.Obtaining good effect aspect energy-conservation and the maintenance vehicle active safety.
