Whether the state of left/right turn confirms etc., obtains the current Ready state of electric car and electric car with this
Left-hand rotation lamp state/right-hand rotation lamp state etc..Specifically, in the initial state, whether signals of vehicles acquisition system determines vehicle
Ready, if then determining whether the lighting control system of electric car is normal, and log-on data acquisition device is adopted when the judgment result is yes
Collect the status informations such as vehicle current travel speed and steering wheel angle, sends collected status information after the completion of acquisition
It assists driving the control system in exchange system to intelligent steering wheel.Since requirement of real-time of the electric car to data is higher,
Therefore it when acquisition data failure or transmission data failure occurs in data acquisition device, then needs to resurvey under current time
The status information of electric car simultaneously retransmits after acquiring achievement to control system, just can guarantee the electronic vapour determined in this way
The accuracy for the result whether vehicle needs to turn to.
S22, predict steering wheel rotation when, according to the steering wheel rotational angle of prediction and current travel speed, really
It is fixed whether to meet steering condition, S23 is thened follow the steps if meeting；It is no to then follow the steps S24, it may be assumed that return step S11.
In this step, control system, for when determining that steering wheel needs to turn to, Xiang Dengxian system to send control letter
Number, so that lamp shows system and is controlled according to the control signal the light on and off of the flexible light source on steering wheel.Above-mentioned control system
System may be implemented to combine multi-signal output control signal, shows system by control lamp and drives lighting and putting out for flexible light source

In this step, control system is when detecting steering wheel rotation, after determining steering wheel current operation angle, first
According to the current travel speed of the electric car currently got, determine corresponding when the corresponding turn signal of current travel speed is bright
Minimum steering angle, then determine whether steering wheel current operation angle meets the minimum steering angle of left-hand rotation or right-hand rotation, if meeting
Then determine that electric car can execute steering operation.
It should be noted that minimum steering angle а refers to when steering wheel turn signal is bright under different travel speeds corresponding turn
To angle, minimum steering angle а is obtained by sufficient threshold testing or by machine learning.Such as minimum steering angle is
а, then steering angle indicates left-hand rotation or critical section of turning right at (- а ,+а), and 0 ° corresponds at steering wheel equalization point.Work as steering wheel
After steering angle exceeds threshold interval, then it represents that electric car will execute steering operation, also need to sentence as turning left still to turn right
Break the actual size relationship of current wheel steering angle and minimum steering angle.For example, working as steering wheel angle <-а, then it represents that this
When minimum steering angle in left-hand rotation lamp when bright, characterization electric car can execute left-hand rotation operation；Work as steering wheel angle >+а, then table
Show be now in right-hand rotation lamp it is bright when minimum steering angle, characterization can execute right-hand rotation operation.It is carried out so that minimum steering angle is 15 ° as an example
Illustrate, the current steering wheel rotational angle detected is+20 °, is greater than+15 °, it is determined that current steering wheel rotational angle can drive
Right turn lamp is bright, i.e., electric car can execute right-hand rotation operation in next step, namely determine that electric car needs to turn right；If detection
The current steering wheel rotational angle arrived is -20 °, -20 ° < -15 °, it is determined that current steering wheel rotational angle can drive left steering lamp
It lights, that is, determines that electric car can execute left-hand rotation operation in next step.
It is worth noting that, the difference of the travel speed of electric car, corresponding minimum steering angle is different.For example, when electricity
Electrical automobile current driving speed be less than 30km/h when, wheel steering lamp when bright it is corresponding minimum steering angle be 15 °；If electronic vapour
The travel speed of vehicle [30km/h, 70km/h) between, then minimum steering angle is set as 10 °；If the travel speed of electric car
[70km/h, 140km/h) between, then minimum steering angle is set as 7 °.
It should be noted that also need to be arranged hard-over θ, general value is 35 °, steering wheel angle no more than (- θ,
+θ).Meanwhile no matter steering wheel angle is much, and lamp can only all be kept to show the flexible light source point of system left-half or right half part
It is bright.
