1. An automotive electronic control unit configured to control operation of direction indicators of a motor vehicle based on motor vehicle-related data,
the automotive electronic control unit is configured to:
receive current steering wheel angle (α) and motor vehicle speed (v),determine an initial steering wheel angle (α0) when a direction indicator is activated,determine minimum and maximum steering wheel angles (αmin, αmax) reached during when the direction indicator is active, the minimum and maximum steering wheel angles (αmin, αmax) representing the maximum steering wheel angles reached by the steering wheel while steering to the right and to the left, respectively,compute a steering wheel release angle (αr) based on the current motor vehicle speed (v), the steering wheel release angle (αr) representing the steering wheel angle (α) beyond which the motor vehicle's steering wheel is to be turned in the direction indicated by the active direction indicator to cause, when the steering wheel is turned in the opposite direction, the automatic deactivation of the active direction indicator,determine if and when to deactivate the active direction indicator based on the current steering wheel angle (α), the initial steering wheel angle (α0), the minimum and maximum steering wheel angles (αmin, αmax), and the steering wheel release angle (αr); the automotive electronic control unit is further configured to:
recognize a maneuver performed by the motor vehicle, andadapt active direction indicator deactivation strategy based the recognized maneuver; wherein recognizing a maneuver performed by the motor vehicle comprises:
computing steering wheel angle thresholds as a function of the current motor vehicle speed (v); anddetermining a maneuver performed by the motor vehicle based on the current steering wheel angle (α) and the steering wheel angle thresholds (αsmin, αsmax, αdmin, αdmax); and wherein determining a maneuver performed by the motor vehicle based on the current steering wheel angle (α) and the steering wheel angle thresholds (αsmin, αsmax, αdmin, αdmax) comprises:
measuring times during which the current steering wheel angle (α) satisfies predetermined relations with the steering wheel angle thresholds (αsmin, αsmax, αdmin, αdmax); anddetermining the maneuver performed by the motor vehicle based on the measured times. |
