Fig. 1 is the hydraulic schematic diagram of EESC electromagnetic valve.Master brake cylinder 1, first pressure sensor 201, first transfer valve 301, second transfer valve 302 and the first pedal simulator 401 can be used as a relatively independent entirety as seen from Figure 1, through the first transfer valve 301, the adjustment of the second transfer valve 302, brake oil flow first pedal simulator 401 of master brake cylinder 1, and the intention of chaufeur is identified according to the first pressure sensor 201.Braking liquid required for car brakeing is from boost pump 7, high pressure accumulator 5 and the first pressure charging valve 601, second pressure charging valve 602, when needs energy regenerating, the first pressure charging valve 601, second pressure charging valve 602 can stop part braking liquid to enter the first brake cylinder 1301, second brake cylinder 1302.The pulse that boost pump 7 produces can be filtered in high pressure accumulator 5 one aspect, makes pressure source more stable; In addition on the one hand, if when boost pump 7 pumping rate can not meet braking requirement, compensated by high pressure accumulator 5.The braking liquid of the first brake cylinder 1301, second brake cylinder 1302 can be monitored by the second pressure sensor 202, vehicle's current condition mechanism of power generation kinetic force can be calculated according to vehicle present speed, be realized the closed loop control of synthetical restraint situation by the difference of pressure of the first pressure sensor 201 and the second pressure sensor 202 and generator brake capabilities might.First brake cylinder 1301, second brake cylinder 1302 connects the first reducing valve 901 respectively and the second reducing valve 902, first reducing valve 901, second reducing valve 902 connects protective valve 10.The pressure that first reducing valve 901, second reducing valve 902 completes the first brake cylinder 1301, second brake cylinder 1302 respectively regulates, and protective valve 10, when reducing valve lost efficacy, ensures the deceleration and stopping performance meeting wheel.Simultaneously when the electric function of electromagnetic valve lost efficacy, directly flow to the first brake cylinder 1301, second brake cylinder 1302, to complete the partial brake usefulness of vehicle by the braking liquid of master brake cylinder 1.The principle of work of the second brake circuit is identical with the first above-mentioned brake circuit, is not repeating.
The hydraulic figure that Fig. 2 is EESC electromagnetic valve when drive wheel completes braking by electrical generator separately.As seen from Figure 2, under this state, chaufeur has started braking, but the braking liquid of master brake cylinder 1 does not remove brake cylinder, and flows to the first pedal simulator 401 through the first transfer valve 301, second transfer valve 302 and produce pressure.According to the force value that the first pressure sensor 201 detects, drive motor 8 and boost pump 7 are started working and are started to set up the pressure of demand.The generate electricity brake torque that produces of this working process drive wheel can meet the braking requirement of vehicle, therefore the braking oil pressure that boost pump produces can not open the first pressure charging valve 601, second pressure charging valve 602 of normally off, and the braking of wheel has been come by power generation torque completely.
