Embodiment Construction

[0078] The invention relates to a device and a method for assisting the driving of a vehicle, one object of the invention is to calculate the transmission coefficient of a screen with variable transmission. The screen with variable transmittance is arranged in the field of view of the driver of the vehicle, between the driver and the road scene. According to different embodiments of the invention, a screen with variable transmittance may consist of:

[0079] - the actual screen which is placed between the driver and the windshield and which can be folded back, for example in the manner of a sun visor,

[0080] - the windshield itself, or

[0081] - A pair of spectacles, said pair of spectacles being worn by the driver, such as sunglasses or corrective spectacles.

[0082] The transparency level of the screen with variable transmittance is defined by the transmittance coefficient of the screen with variable transmittance, which is driven by the auxiliary device, and between t...

Abstract

The invention relate to a driving assistance device for motor vehicle (11) including a variable-transmittance display intended to be placed between a road scene, located in front of the vehicle (11), and a driver of the vehicle. Said device includes a plurality of sensors capable of recovering data representing the environment in which the vehicle (11) is located. Said device is configured to control a transmission factor of the variable-transmittance display. Said driving assistance device is characterized in that it is configured to take into account the data recovered by the sensors and calculate the transmission factor by combining said data.

Description

technical field [0001] The invention relates to a device and a method for assisting the driving of a motor vehicle. [0002] The invention relates to a method and a device aimed at assisting the driving of a motor vehicle, in particular when the exterior brightness or changes in the exterior brightness may disturb the driving of the driver. Background technique [0003] While the vehicle is moving, the driver of the vehicle must permanently observe the exterior of the vehicle to be alerted to any hazards that could easily lead to an accident. Today, drivers' vision is often disturbed by external brightness, either due to glare from the sun, due to the light of oncoming or following vehicles or even sudden changes in brightness when entering or exiting a tunnel. [0004] To improve driver comfort and safety, several solutions have been proposed. One of the solutions is to use a screen with variable transmission, for example in the form of glasses worn by the driver, the tra...
