A method for assisting the daytime driving of a motor vehicle, including the steps of: placing at least one variable-transmission screen between the driver of the motor vehicle and the road scene in front of the vehicle, measuring, by means of at least one sensor, the brightness of the road scene in front of the vehicle, and processing the brightness measurement signal to convert it into a signal for controlling the coefficient of transmission of the variable-transmission screen. In one embodiment, the method includes the further step of transmitting the control signal by remote control waves to a receiver fitted to the variable-transmission screen for modulating the coefficient of transmission of the variable-transmission screen as a function of the brightness measured by the sensor.
A method for assisting the daytime driving of a motor vehicle, including the steps of:
A device for assisting the daytime driving of a motor vehicle, including:
A variable-transmission screen adapted to be placed between a driver of a motor vehicle and a road scene (SR) in front of said vehicle, wherein a coefficient of transmission (CT) of said variable-transmission screen is variable according to a pulse width modulation (PWM) mode between a maximum value (CTMAX) and a minimum value (CTmin), said coefficient of transmission (CT) of said variable-transmission screen being controlled by a control unit according to a wireless communication protocol, by means of remote control waves (OT) transmitted by a transmitter of said control unit and received by a receiver.
