Warning signal controlling method for use in vehicle, involves outputting optical warning signals to driver, and suppressing output of warning signal even if given minimum distance for forward-driving vehicle falls below value

摘要

The method involves providing an output of a warning signal and/or a set of warning signals, when a preset minimum distance for a forward driving-vehicle falls below a value. The warning signals with less priority is outputted and a higher warning stage is not activated using a recognized driver response and/or driver intention. Optical warning signals are outputted to a driver, where the output of the warning signal is suppressed even if the given minimum distance falls below the value.
