Abstract: A system detects a lack of vigilance by a driver of a motor vehicle. The system includes a first monitoring unit to assess whether the vigilance of the driver is or is not above a vigilance threshold, at least two distinct loudspeakers, and a sound stage generator to control the at least two loudspeakers so as to simulate a stereophonic sound originating from a virtual sound source that is mobile relative to a seat of the driver when the vigilance of the driver becomes less than the vigilance threshold.

Abstract: A system detects a lack of vigilance by a driver of a motor vehicle. The system includes a first monitoring unit to assess whether a vigilance of the driver is or is not above a vigilance threshold, at least one second monitoring unit to identify at least one type of danger linked to a trajectory and/or to an environment of the vehicle, at least two distinct loudspeakers, and a sound stage generator to control the at least two loudspeakers so as to simulate a sound originating from a virtual sound source that is mobile relative to a seat of the driver. The sound stage generator simulates a sound stage with mobile virtual source when the vigilance level detected is below the threshold and a danger of given type is identified.
