Description
Technical field
The invention belongs to electric vehicle engineering field, specifically, the present invention relates to a kind of pure electric automobile regeneration brake system.
Background technology
In today that energy shortage and air pollution are increasingly severe, initiative development electric automobile just progressively becomes the common recognition of people.Compared with conventional truck, pure electric automobile has an absolute advantages, it is possible to a part of braking energy of recycling, it is achieved regenerative braking, extends pure electric automobile continual mileage, improves energy utilization efficiency, saves the energy.
The braking moment that the brakes of the typically no conventional truck of regenerative braking force of pure electric automobile provides is big, pure electric automobile is compared with tradition vapour (bavin) oil car, lack electromotor auxiliary braking, braking (deceleration) works mainly by wheel drag, braking effect and occupant experience poor, and safety and comfortableness are relatively low.
Summary of the invention

Described motor is permagnetic synchronous motor or AC induction motor.
When pure electric automobile is in brake hard operating mode, hydraulic brake system plays a major role, and produces brake force, and regenerative braking device helps out.
When pure electric automobile is in mild or moderate damped condition, regenerative braking device is responsible for moderating process, and stopped process is completed by hydraulic brake system.
When pure electric automobile is in long down hill braking operating mode, pure electric automobile works in pure braking mode.
The pure electric automobile regeneration brake system of the present invention, energy recovery section braking energy, raising capacity usage ratio in braking procedure, good braking effect, also has the mechanical wear reducing the mode of braking such as machinery, hydraulic pressure, realize more accurate control for brake, and reduce the braking heat fading phenomenon etc. produced in orthodox car braking procedure because temperature raises, improve safety and the comfortableness of pure electric automobile.
Accompanying drawing explanation
This specification includes the following drawings, it is shown that content respectively:
Fig. 1 is the structural representation of pure electric automobile regeneration brake system of the present invention；
Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is described in further detail, it is therefore an objective to help those skilled in the art that the design of the present invention, technical scheme are had more complete, accurate and deep understanding, and contribute to its enforcement.
As shown in Figure 1, the invention provides a kind of pure electric automobile regeneration brake system, including motor, hydraulic brake system and regenerative braking device, hydraulic brake system includes master cylinder, ABS executor, ABS control unit, fluid pressure governor, hydraulic braking control unit and the wheel drag being installed on wheel place, hydraulic brake system has ABS system (anti-blocking brake system), hydraulic braking control unit is connected with fluid pressure governor and ABS control unit, fluid pressure governor is also connected with ABS executor, ABS control unit controls wheel drag by ABS executor, to regulate the size of front and back wheel frictional force, and then control running state of wheels.Regenerative braking device includes regenerative braking control unit and accumulator, regenerative braking control unit is connected with accumulator and electric machine controller, motor is by its braking moment of motor controller controls, motor works in generating state when producing braking moment, is electric energy by changes mechanical energy and passes to accumulator by inverter and be charged.
Specifically, the regenerative braking of pure electric automobile, it is exactly utilize the electric braking of motor to produce opposing torque to make vehicle deceleration or parking, its essence is the supply frequency that the rotational frequency of drive motor rotor exceedes motor, motor works in generating state, is that electric energy is charged the battery by the reverse fly-wheel diode of inverter by changes mechanical energy.
Braking of battery electric vehicle can be divided into following Three models, and different mode should be aided with different control strategies:
1, brake hard: corresponding to braking deceleration more than 2m/S2Process, the consideration for safety aspect should based on mechanical friction braking, and electric braking only helps out, namely hydraulic brake system plays a major role, produce brake force, regenerative braking device helps out.When bringing to a halt, according to the difference of initial velocity, ABS control unit on car can control wheel drag by ABS executor, it is provided that corresponding mechanical friction brake force.
2, mild or moderate braking: corresponding to automobile braking procedure in normal conditions, such as red light or parking etc. of pulling in, can be divided into moderating process and stopped process.Regenerative braking device is responsible for moderating process, and stopped process is completed by hydraulic brake system.
3, braking during the long descending of automobile: when the long descending of electric automobile typically occurs in gentle slope under sky way, when required braking force is little, can work in pure braking mode completely.
By three of the above braking mode it can be seen that except brake hard, other both of which can apply regenerative braking, energy feedback brake produced, to dc bus, charges the battery.
Above in association with accompanying drawing, the present invention is exemplarily described.Obviously, the present invention implements and is not subject to the restrictions described above.As long as have employed the improvement of the various unsubstantialities that the design of the method for the present invention carries out with technical scheme；Or not improved, the above-mentioned design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
