The step of saving manually opened steering lamp system hardwire switch group (i.e. turning indicator control 3), makes left and right turn signal in vehicle lane change
It automatically turns in the process or before turning.
The present invention carries out booting-self controller to turn signal using two schemes:
(1) when navigation system GPS7, which obtains data, automatically turns on steering lamp system: the turn signal opening time is defined as
Before vehicle reaches turning 4-6s, road object of reference near vehicle should be obtained by radar at this time and reaches turning distance S, and
Vehicle speed sensor obtains real-time speed v, 4s < t=S/v < 6s, determines that vehicle will turn at this time, turn signal pre-cooling.
(2) when obtaining data automatic opening steering lamp system during lane change: determining rear according to radar and camera 6
When there are other vehicles in 15m, pass through the danger of MP5 warning note driver rear, it is proposed that cancel lane change；When rear 15m is without other
When vehicle, is set during lane change and turn to wheel angle in vehicle as β, outer steering wheel angle is α, ground and two sides main shaft phase
Intersection point distance is B, and vehicle wheel base is L (taking 2500mm), then has cot α=cot β+B/L, wherein 0 90 ° of < α <, when α minimum value
When turning radius it is maximum, R (max)=L/sin α (min).Meeting lane change condition when defining α=3 °, (angle is less than 3 ° not as change
Road decision condition), steering wheel angle range is generally 0-900 °, and corresponding direction disk angle is 30 ° at this time, and is remained unchanged 3 seconds,
Then it is determined as during vehicle lane change, self-starting in the case that turn signal is not opened.
Retain the necessity that orthodox car turns to lamp system hardwire switch: when network signal goes wrong for one side
When, such as when vehicle driving is at network signal not good area, car networking cloud platform and vehicle can not carry out data biography at this time
Defeated, we can manually control turn signal using turn signal system entity key, avoid because opening turn signal not in time
And accident occurs, while physical button has priority control；On the other hand, federation's still faithful to traditional driving body of some people
It tests, dotes on and use turning indicator control manually.
