Detailed description of the invention
Of the present utility model embodiment is described below in detail, and the example of described embodiment is shown in the drawings, the most ad initio
Represent same or similar element to same or similar label eventually or there is the element of same or like function.Below by ginseng
It is exemplary for examining the embodiment that accompanying drawing describes, and is only used for explaining this utility model, and it is not intended that to of the present utility model
Limit.
Below in conjunction with accompanying drawing, the energy feedback system of the electric automobile according to this utility model embodiment and electronic vapour are described
Car.
Before describing the energy feedback system of electric automobile of this utility model embodiment, first electric automobile is carried out
Describing, the electric automobile proposed in this utility model embodiment has and slides feedback and travel gear, is called for short B gear, if electronic
Automobile has motion gear (S gear), then sliding feedback and travel gear can be motion gear, say, that if electric automobile is linked into S
Gear, then it is assumed that what vehicle was linked into is to slide feedback to travel gear equally.If electric automobile does not has S to keep off, then slide feedback and travel
Gear can time on the basis of P, N, R and D of electric automobile keep off a gear newly increasing, if electric automobile is linked into this
Gear, the most normally travels neutralization and is linked into during D gear essentially identical, be distinguished as, when vehicle is in nature sliding state, can carrying out
Slide energy feedback.
Natural sliding state refers to: vehicle accelerator pedal in the process of moving and brake pedal are not the most operated, at vehicle
In the transport condition naturally slided.That is: driver does not brake does not has oil supply yet, and vehicle relies on the process that inertia travels naturally.
Fig. 1 is the structured flowchart of the energy feedback system of the electric automobile according to one embodiment of this utility model.Such as Fig. 1
Shown in, according to the energy feedback system 100 of the electric automobile of one embodiment of this utility model, including: vehicle-state detection dress
Put 110, gear detection device 120 and controller 130.Gear detection device 120 is for example: shift sensor (gear on-off).
Wherein, vehicle condition detection device 110 is used for detecting whether electric automobile is in nature sliding state.Shift detection
Device 120 is used for whether detecting current shift for sliding feedback traveling gear.Controller 130 respectively with vehicle condition detection device
110 are connected with gear detection device 120, to be in nature sliding state and current shift for sliding feedback traveling at electric automobile
Control vehicle entrance during gear and slide feedback pattern.
As a concrete example, vehicle condition detection device 120 includes: signal detector and processor (do not have in Fig. 1
Illustrate), signal detector is used for detecting brake signal and throttle signal.Processor is connected with signal detector, with at signal
Detector is not detected by when brake signal and throttle signal determining that electric automobile is in nature sliding state.If it is to say,
It is not detected by brake signal and throttle signal, illustrates that driver does not has brake pedal and gas pedal, therefore, vehicle
It is in nature sliding state.
It should be noted that whether vehicle can carry out energy feedback, the electrokinetic cell also depending on electric automobile is
No can carry out energy regenerating (that is: the need of charging), only in the case of electrokinetic cell can charge, can carry out
Energy regenerating, therefore, shown in Fig. 1, the energy feedback system 100 of the electric automobile of this utility model embodiment, also include:
Battery condition detection apparatus 140, battery condition detection apparatus 140 is for detecting the state-of-charge of electrokinetic cell, and battery status is examined
Survey device 140 to be connected with controller 130.Gear and power is travelled for sliding feedback when vehicle is in nature sliding state, gear
In the case of battery is chargeable, controller 130 just controls electric automobile entrance and slides feedback pattern.
Specifically, work process such as Fig. 2 institute of the energy feedback system 100 of the electric automobile of this utility model embodiment
Show, detect brake signal, throttle signal, shift signal, power battery charged state, speed, the rotating speed etc. of driving motor, control
Device 130 judges whether to enter feedback pattern and enter which kind of feedback pattern with this.When brake pedal is operated and power
When battery charge state is less than predetermined state-of-charge, entering feedback braking pattern, under feedback braking pattern, controller 130 can
To draw feedback coefficient according to speed and brake signal etc. by tabling look-up, further according to driving the rotating speed of motor and can be used for feedback
Energy meter calculates a feedback moment of torsion, and the feedback moment of torsion calculated takes little with maximum feedback moment of torsion, finally the feedback obtained is turned round
Square is multiplied by feedback coefficient and obtains feedback braking moment of torsion, and carries out Brake energy recovery.When vehicle is in nature sliding state, power
When battery charge state is B shelves less than predetermined state-of-charge and current shift, enters and slide feedback pattern, sliding feedback pattern
Under, controller 130 is tabled look-up according to speed and is drawn feedback coefficient, further according to driving the rotating speed of motor and can be used for the power of feedback
Calculate a feedback moment of torsion, and take little with maximum feedback moment of torsion, finally the feedback moment of torsion obtained is multiplied by feedback coefficient and obtains
Slide feedback moment of torsion under current vehicle speed, and carry out energy regenerating.
It should be noted that predetermined state-of-charge presets and obtains, its effect is when power battery charged state is less than
During predetermined state-of-charge, it is allowed to power battery charging.
The energy feedback system of the electric automobile according to this utility model embodiment, is in nature sliding state at vehicle
Under, the feedback carrying out sliding energy can be chosen whether as required, in order to permissible when being made without sliding energy feedback
Ensure that vehicle has enough coasting distances, the course continuation mileage of vehicle of can effectively deducting a percentage when needing and carrying out sliding energy feedback,
Vehicle is made to have more preferable driving experience.
