Electrically connected with the input of controller；The controller is connected with batteries, alternating current generator and electromagnetic brake respectively, control
Device is used to control batteries to be powered alternating current generator, electromagnetic brake respectively.
Further scheme, the handle accelerator includes advance switch, retrogressing switch and Hall accelerator, the advance
Switch, retrogressing switch are respectively provided at the front and back ends of operation handle, and being controlled to advance by operation handle is switched, retreats what is switched
Closure disconnects.
Further scheme, the stator and rotor of the alternating current generator are connected by cable with controller respectively.
Further scheme, the output voltage signal C of the Hall accelerator3、C4, its numerical values recited is by manipulator
The action of handle and change, its excursion is 0-10V.
When operation handle is in middle position, C3=C4=0V；When being pushed away before operation handle, 0<C3≤ 10, and C3Value with
The increase of amplitude is pushed away before operation handle and is increased；When operation handle post-tensioning, 0<C4≤ 10, and C4Value with accelerator hand
The increase of handle post-tensioning amplitude and increase.
Further scheme, the controller is the ACE2-350 of Italian ZAPI companies.
I.e. the present invention realizes the transmission and closing of signal using existing ACE2-350 as controller, is not related to it
Internal structure and principle.
The present invention by operation handle come the signal output of joystick accelerator, when operation handle is in middle position, suddenly
The output voltage signal C of your formula accelerator3=C4=0V；When being pushed away before operation handle, switch closure of advancing (C2=1), while Hall-type
Accelerator output voltage signal C3Excursion be：0<C3≤ 10, and C3Value with the increase that amplitude is pushed away before operation handle
Increase；When operation handle post-tensioning, switch closure (C is retreated1=1), while Hall accelerator output voltage signal C4Change
Scope is：0<C4≤ 10, and C4Value increase with the increase of accelerator handle post-tensioning amplitude.
Brake switch is located at the bottom of brake pedal, can then control the signal of brake switch defeated by operating brake pedal
Go out, when brake pedal, brake switch closure (C5=1)；When loosening the brake, brake switch disconnects (C5=0).Store
Battery pack controls to be powered alternating current generator and electromagnetic brake by controller.
Parking brake in this brakes selects electromagnetic brake, and service brake uses alternating current generator electric current in itself
Regenerative braking, and without brake；Brake pedal is connected with brake switch, and brake switch is entered by controller with electromagnetic brake
Row electrical connection；As long as pedal force overcomes the returning place force of brake switch, pedal force very little (about 5N), the driver comfort of driver
It is good.Electromagnetic brake is only used for stopping brake, does not now have relative motion, friction plate between the friction plate and brake disc of brake
Abrasion it is small, brake life is long.
So brakes of the invention can realize Brake energy recovery, energy saving；Brake pedal force is small, driving comfort
Property improve；The service life of brake bush is improved.

Vehicle driving brakes (relief lever braking)：(rotating speed of alternating current generator 10 is more than vehicle in the process of moving
0), relief lever 5, controller 8 detects the voltage signal C3 or C4 of the output of Hall accelerator 4 from large to small, then control
The cut-out of device processed 8 batteries 9 are powered to the stator of alternating current generator 10, and motor inertia is rotated, while the control battery of controller 8
The rotor of 9 pairs of alternating current generators 10 of group is powered (comparatively speaking power is smaller), and it produces magnetic field, the physics that the magnetic field passes through rotor
Rotate, the winding of cutting stator, then stator induces electromotive force, and this electromotive force is charged by controller 8 to batteries 9,
Realize Brake energy recovery.The rotor stress of alternating current generator 10 is slowed down simultaneously, realizes braking.Its severity of braking is by controller 8
It is controlled according to control strategy, control strategy regulation, now severity of braking is relatively weak, and braking distance is relatively long, and it is right to brake
The impact of human pilot is small, and driver comfort is high, for generally braking.
Vehicle driving braking (braking of release brake pedal)：(rotating speed of alternating current generator 10 is more than vehicle in the process of moving
0), while relief lever 5 and brake pedal 1, controller 8 detects signal C5=0 (the now electromagnetic brakings of brake switch 2
Device 11 is in release conditions)；The cut-out of controller 8 batteries 9 are powered to the stator of alternating current generator 10, and motor inertia is rotated, together
When controller 8 control batteries 9 rotor of alternating current generator 10 is powered (comparatively speaking power is smaller), produce magnetic field, the magnetic
Field being physically rotated by rotor, and the winding of cutting stator, stator then induces electromotive force, and this electromotive force passes through controller 8
Charged to batteries 9, realize Brake energy recovery.The rotor stress of alternating current generator 10 is slowed down simultaneously, realizes braking.Severity of braking
It is controlled according to control strategy by controller 8, control strategy regulation, now severity of braking is relatively strong, and braking distance is relative
It is shorter, brake relatively larger to the impact of human pilot, driver comfort is slightly poor, in emergency circumstances braking.
Vehicle parking is braked：When the vehicle is stopped, controller 8 detects the rotating speed of alternating current generator 10 equal to 0；Release braking
Pedal 1, controller 8 detects the signal C5=0 of brake switch 2, and controller 8 cuts off electricity of the batteries 9 to electromagnetic brake 11
Magnet is powered, and now electromagnetic brake 11 is in on-position, realizes stopping brake.
It is upper described, only it is presently preferred embodiments of the present invention, not make any formal to technical scheme
Limitation.Without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these change and
Improve still in the range of technical scheme and belong to the scope of claimed invention.
