Abstract
A method for automatically controlling a direction of travel indicator of a vehicle having the following steps: receiving a signal for the chronologically limited activation of the direction of travel indicator, chronologically limited activation of the direction of travel indicator after reception of the signal for the chronologically limited activation of the direction of travel indicator, starting a timer for a measurement interval after reception of the signal for the chronologically limited activation of the direction of travel indicator, checking a steering angle measurement signal during the measurement interval, and deactivation of the direction of travel indicator as a function of the checking of the steering angle measurement signal.
Claims9
A method for automatically controlling a direction of travel indicator of a vehicle activated for signaling a lane change for a limited time, the method comprising:
- receiving a signal for a chronologically limited activation of the direction of travel indicator,
- performing chronologically limited activating of the direction of travel indicator after reception of the signal for the chronologically limited activation of the direction of travel indicator,
- starting a timer for a measurement interval after reception of the signal for the chronologically limited activation of the direction of travel indicator,
- checking a steering angle measurement signal indicating a steering movement during the measurement interval, and
- generating a deactivation signal and deactivating the direction of travel indicator as a function of the deactivation signal in response to the steering angle measurement signal indicating that the steering movement is opposite to the direction indicated by the direction of travel indicator,
- generating the deactivation signal and deactivating the direction of travel indicator as a function of the deactivation signal in response to the steering angle measurement signal indicating that a lane change of the vehicle is aborted, and
- generating the deactivation signal and deactivating the direction of travel indicator as a function of the deactivation signal in response the steering angle measurement signal indicating no corresponding steering movement during the measurement interval.
A device for automatically controlling a direction of travel indicator activated for signaling a lane change for a limited time, of a vehicle, the device comprising:
- a first timer for the chronologically limited activation of the direction of travel indicator after reception of a signal for the chronologically limited activation of the direction of travel indicator,
- a second timer for starting a measurement interval after reception of the signal for the chronologically limited activation of the direction of travel indicator, and
- means for checking a steering angle measurement signal indicating a steering movement during the measurement interval and for:
- generating a deactivation signal and deactivating the direction of travel indicator as a function of the deactivation signal in response to the steering angle measurement signal indicating that the steering movement is opposite to the direction indicated by the direction of travel indicator, and
- generating the deactivation signal and deactivating the direction of travel indicator as a function of the deactivation signal in response to the steering angle measurement signal indicating that a lane change of the vehicle is aborted, and
- generating the deactivation signal and deactivating the direction of travel indicator as a function of the deactivation signal in response the steering angle measurement signal indicating no corresponding steering movement during the measurement interval.
