Description
Technical field
The utility model relates to a kind of differential control system of miniature 4 wheel driven wheel hub motor battery-driven car, belongs to the differential control system technical field of wheel hub motor battery-driven car.
Background technology
Battery-driven car will be realized the driving habit with orthodox car, satisfies simultaneously the high efficiency smart operation, must use Electronic differential control at the battery-driven car of In-wheel motor driving, otherwise is difficult to realize the battery-driven car of independent four-wheel is unified control.The Regenerative Braking Technology part that also is absolutely necessary in modern battery-driven car, it can improve the power utilization rate, reduces discharging, has protected better storage battery simultaneously, prolongs the service life of electrokinetic cell, has also improved alerting ability and the validity of braking.
Differential is when vehicle needs to turn in the process of moving, and for turning to of realizing estimating, the inside and outside wheel of the vehicle that travels is taked certain velocity contrast, the needs that satisfied driving turns to.Electronic differential is the rotating speed that the mode of employing software and combination of hardware is controlled each drive wheel, makes drive wheel satisfy certain strategy relation and moves with friction speed, guarantees that the wheel of control does not drag sliding or slippage in the process of moving.Traditional internal-combustion engines vehicle carries out differential by the mechanical differential gear box with speed reduction gearing to be processed, and realizes a kind of like this function, the assurance vehicle during at Turning travel or by the tunnel inside and outside it wheel under friction speed, move.Because according to the running car kinematics, vehicle in the process of moving, the driving wheel of the right and left is in same amount of time, the actual length that rolls across is normally different, particularly significantly during curve traffic, the distance difference of left and right wheels motion is just more obvious.How to realize that differential control is miniature 4 wheel driven wheel hub motor battery-driven car problem demanding prompt solution.
Summary of the invention
In order to realize above-mentioned purpose, the purpose of this utility model is to provide a kind of differential control system of miniature 4 wheel driven wheel hub motor battery-driven car.
The utility model comprises driving switch, rotary angle transmitter, acceleration pedal jaw opening sensor, brake switch, HTE platform, driving governor one, driving governor two, driving governor three, driving governor four; Driving switch connects the HTE platform, and rotary angle transmitter connects the HTE platform, and the acceleration pedal jaw opening sensor connects the HTE platform, and brake switch connects the HTE platform; The HTE platform connects driving governor one, and the HTE platform connects driving governor two, and the HTE platform connects driving governor three, and the HTE platform connects driving governor four.
Principle of the present utility model: driving switch is realized the gear conversion, the HTE platform reads driving switch gear change over signal, the HTE platform reads the turn sign of rotary angle transmitter, the HTE platform reads the pedal aperture signal that the acceleration pedal jaw opening sensor gathers, and the HTE platform reads the speed-slackening signal of brake switch, and the HTE platform is exported four road analog quantitys, four road analog quantitys are transported to respectively driving governor one as throttle control signal, driving governor two, driving governor three, driving governor four.
The beneficial effects of the utility model: control method is simple, and effectively, it is high to carry out efficient;
Description of drawings
Figure one is structured flowchart of the present utility model.
