As shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, working process of the present invention is specifically implemented as follows:
In car running process, system can realize chaufeur braking, motor braking and chaufeur and three kinds of braking modes of motor coordination braking, when the functions such as ABS, TCS and ESP do not work, electromagnet 111 is in off-position, bearing pin 112 makes leading screw 118 separate with master cylinder connecting link 117, when the functions such as ABS, TCS and ESP work, electromagnet 111 is in "on" position, bearing pin 112 is connected as a single entity leading screw 118 and master cylinder connecting link 117, the two can move axially among a small circle one, object is in the time of the work such as ABS, TCS and ESP, ensures reliably decompression.
One, chaufeur braking mode:
In the time that motor power-assisted lost efficacy, chaufeur is stepped on brake pedal 116 and is driven master cylinder connecting link 117, promotes the first master cylinder piston 125 work by rubber reaction plate 103, implements separately braking.
Two, motor braking pattern:
In the time of needs brake snub, the work of ECU (Electrical Control Unit) control DC machine, DC machine drives ball-screw, acts on rubber reaction plate 103 promote the first master cylinder piston 125 enforcement brakings through effect ring 104, makes car deceleration.
Three, chaufeur and motor coordination braking mode:
In normal brake application process, chaufeur is stepped on brake pedal 116, pipe link 113 promotes master cylinder connecting link 117 and advances, master cylinder connecting link 117 acts on rubber reaction plate 103, while motor rotarily drives leading screw 118 and moves, and leading screw 118 acts on rubber reaction plate 103 through effect ring 104, and rubber reaction plate 103 acts on the first master cylinder piston 125, produce brake fluid pressure, and then produce braking force.In this process, ECU (Electrical Control Unit) is all the time according to brake pedal position sensor 114 signals, obtain rotor 105 target angle displacements and leading screw 118 target locations, control DC machine and drive leading screw 118 to follow the tracks of its target location, by rotor angular-motion transducer 121 signals, the correction of leading screw displacement pickup 119 signals is drawn to actual accurately leading screw 118 positions.In braking procedure, ECU (Electrical Control Unit) constantly receives leading screw 118 actual position signals of leading screw displacement pickup 119 and makes comparisons and draw leading screw 118 position deviation e(e=leading screw target location-leading screw actual positions with leading screw 118 target locations), according to leading screw, 118 position deviation e judge whether to arrive target location, and e1 is the deviation threshold value setting.Work as e>e1, motor power-assisted deficiency, the driven by motor leading screw 118 increasing power-assisted of advancing; When-e1≤e≤e1, motor power-assisted is suitable, and motor maintains the original state; As e <-e1, motor power-assisted is excessive, and driven by motor leading screw 118 retreats and reduces power-assisted.
In order to utilize native system to realize the functions such as ABS, TCS and ESP, realize supercharging, pressurize and the decompression of each brake wheel cylinder.The method adopting is: while having one or more wheel cylinders to have decompression demand, other wheel cylinder is implemented pressurize; When any one wheel cylinder does not all reduce pressure demand, each wheel cylinder can be implemented pressurize or supercharging, and the size of motor power-assisted is determined according to the deviation e of leading screw 118 target locations and leading screw 118 actual positions.While implementing decompression, motor contrarotation, drives leading screw 118 to retreat and reduces power-assisted, now because electromagnet 111 is in "on" position, bearing pin 112 is connected as a single entity leading screw 118 and master cylinder connecting link 117, and the two can move axially among a small circle one, and object is that guarantee system reliably reduces pressure.In the time that needs are removed decompression, the size of motor power-assisted is determined according to the deviation e of leading screw 118 target locations and leading screw 118 actual positions.
The ECU (Electrical Control Unit) of control system is provided with control cycle (common 10-30ms), and each control cycle can carry out assignment to actuating unit electromagnetic valve or assist motor again.The theoretical analysis and verification experimental verification, as long as control cycle and reducing valve cutoff port are selected suitably, a control cycle can be reduced to 0, two control cycle from maximum pressure arbitrary wheel cylinder and multiple wheel cylinders can be reduced to 0 from maximum pressure, and this is just for the enforcement of control policy provides theoretical basis.
In the time brake switch work being detected, ECU (Electrical Control Unit) starts to judge according to motoring condition the hydraulic efficiency governing conditions of demand of each road brake wheel cylinder, in each control cycle, some or multiple brake wheel cylinders is carried out to pressure adjusting.While needing supercharging, each electromagnetic valve state remains unchanged; While needing pressurize, the normally open solenoid valve energising connected with corresponding wheel cylinder, closes its hydraulic circuit, and other electromagnetic valve state remains unchanged; Need to reduce pressure time, the normally open solenoid valve power-off connected with corresponding wheel cylinder, in opening, the low pressure accumulator normally closed solenoid valve energising connected with corresponding wheel cylinder, in opening, other electromagnetic valves are all closed, need the wheel cylinder of decompression to be connected with low pressure accumulator through low pressure accumulator normally closed solenoid valve, motor contrarotation, drives leading screw 118 to retreat, the braking liquid of low pressure accumulator and wheel cylinder is drawn back to master brake cylinder 101, realize wheel cylinder decompression.Whole system is exactly constantly to judge like this state of each wheel, and according to its state, it is carried out to pressure adjusting, reaches the object to vehicle ability of posture control.
Above-described embodiment is to further instruction of the present invention, is not limitation of the present invention, any on basis of the present invention structure after simple transformation, all belong to protection scope of the present invention.
