Abstract

A vehicle signaling method and device for alerting drivers approaching from a rear of the vehicle including at least one light emitting signal arranged on an element of the vehicle facing rearward, a velocity measurement sensor for measuring an absolute velocity of the vehicle and a control unit coupled to the velocity measurement sensor for determining if the measured absolute velocity is greater than a threshold velocity. In one embodiment, there is a manual light activation unit which is connected to the control unit and the light emitting signal(s). The manual light activation unit is controlled by the control unit to enable the light emitting signal(s) to be activated only if the measured absolute velocity is less than the threshold velocity. In another embodiment, which can be used separate from or together with the velocity control unit, the device includes a deceleration measurement sensor coupled to the velocity threshold measurement sensor for measuring deceleration of the vehicle and which are activated by the control unit only if the measured absolute velocity is greater than a threshold velocity. A deceleration threshold determining unit then determines if the measured deceleration is greater than a threshold deceleration and the light emitting signal(s) is activated if the absolute velocity is greater than the threshold velocity as determined by the control unit and the measured deceleration is greater than the deceleration threshold as measured by the deceleration threshold determining unit.
