Have issued steering indicating light control signal, the controller of this turn signal can be BCM.Further, it is also possible to by Voice command etc.
Input steering indicating light control signal, here does not limit.
Step S02, if get driver input open left steering modulating signal, judge Current vehicle angle of turn
Whether it is more than dextrad first threshold angle, if it is, steering indicating light is powered to the right, if it is not, then steering indicating light is powered to the left.
In the present embodiment, the direct access Current vehicle angle of turn such as angular transducer can be passed through, for example：It is arranged on
Angular transducer on steering wheel or steering column or the speed ratio according to coaxial tire or speed difference etc. pass through to calculate
The Current vehicle angle of turn obtaining, here does not limit.Current vehicle angle of turn can be judged whether more than the right side by BCM
To first threshold angle, this first threshold angle can be 5 °, 10 °, 15 °, 20 ° etc. naturally it is also possible in order to adapt to not Tongfang
To disk species or be easy to be set according to actual conditions, for example, the first threshold described in the steering wheel monolateral maximum anglec of rotation/4 ＜
The value angular range ＜ steering wheel monolateral maximum anglec of rotation/3；Preferably, described first threshold angle is：7 × steering wheel is monolateral
The maximum anglec of rotation/24.
