By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventors El Idrissi, Hafid (Pantin, FR); Beev, Kostadin (Emerainville, FR); Hue, David (Butry sur Oise, FR); Gratien, Steed (Hacheres, FR); Rocklinger, Marc (Bonne, FR), filed on September 26, 2014, was published online on November 28, 2017, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 9827835 is assigned to Valeo Vision (Bobigny, FR).

The following quote was obtained by the news editors from the background information supplied by the inventors: "The invention relates to a device and a method for assisting in the driving of a motor vehicle.

"The present invention relates to the methods and the devices intended to provide assistance in the driving of motor vehicles, particularly when the outside brightness or variations of outside brightness may disturb the driving of the driver.

"While the vehicle is moving, the driver of a vehicle has to permanently look outside the vehicle to be warned of any danger likely to provoke an accident. Now, the vision of the driver is regularly disturbed by the outside brightness, whether from glare due to the sun, due to the lights of an oncoming vehicle or of a following vehicle, or even by abrupt variation of brightness as when entering or leaving a tunnel.

"In order to improve the comfort and the safety of the driver, a number of solutions have been proposed. One of them consists in using a screen with variable transmission, in the form for example of spectacles worn by the driver, the transparency of which varies as a function of a transmission coefficient applied to the screen. The computation of this coefficient is for example performed from a measurement of brightness by a single sensor situated on the vehicle. Thus, the transmission coefficient is adapted to the ambient brightness detected by the sensor to set the transparency of the screen with variable transmission.

"Nevertheless, this solution does not make it possible to adapt the transmission coefficient to enough situations that can be encountered by the vehicle and which require a particular processing. For example, when a strong light source dazzles the driver, the screen with variable transmission will reduce its transparency and therefore lessen the vision of the driver to prevent the glare. Nevertheless, in this case, if the driver looks at another area of the road that is darker, the reduced transparency of the screen with variable transmission will reduce his or her visibility in this darker area even though a pedestrian or a traffic light that the driver will not see or may barely see may be situated in this area. The danger represented by such a situation will easily be understood.

"The invention aims to mitigate at least some of the drawbacks of the known driving assistance devices and methods."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "For this, the invention relates to a device for assisting in the driving of a motor vehicle, comprising a screen with variable transmission intended to be arranged between a road scene in front of the vehicle and a driver of the vehicle, the device comprising a number of sensors suitable for recovering data representative of the environment in which the vehicle is located, the device being configured to drive a transmission coefficient of the screen with variable transmission, wherein the device is configured to take account of the data recovered by the sensors and to compute the transmission coefficient by combining the data.

"A device according to the invention therefore makes it possible to rely on a plurality of data to allow for the adjustment of the transmission coefficient by the combination of these data, and not to take account only of a single datum. Thus, the screen with variable transmission has a transparency which adapts to the context represented by the various data from the various sensors. For example, if one sensor detects a strong brightness originating from an oncoming vehicle, but another sensor detects that the gaze of the driver is directed toward another point, it is not necessary to reduce the transparency of the screen with variable transmission, all the more so as this reduction of the transparency of the screen with variable transmission could provoke a reduction of the vision of the driver even though his or her gaze is directed toward an area in which a danger may be located, such as another vehicle in an intersection, a traffic light, a pedestrian crossing the road, etc.

"Advantageously and according to the invention, the sensors are suitable for recovering the data representative of the environment out of one or more of the following types of data: The atmospheric conditions such as: rain, wind, snow, mist, etc. . . . the time of day etc. . . . The road environment such as the state of the ground, the glare from another vehicle or from a fixed light source, the nature of the road (bend, tunnel, highway, etc.) the geolocation, the speed of the vehicle, etc. . . . The environment of the driver such as: the orientation of his or her head, the orientation of his or her gaze, etc. . . .

"this list being neither limiting nor exhaustive, numerous other data being able to be used.

"According to this aspect of the invention, one or more of these types of data are used to best compute the optimum transmission coefficient to be applied to the screen with variable transmission.

"Advantageously and according to the invention, the device is suitable for determining a situation in which the vehicle and/or the driver is located from all or part of the recovered data.

"According to this aspect of the invention, the situation is selected from a number of predetermined types of situation that it is important to take into account for the computation of the transmission coefficient. For example, the situations combine one or more of the following alternatives describing the context in which the vehicle is located: driving in daytime or nighttime, sunny, cloudy or rainy weather, town or country driving, passage into a tunnel or not, etc. A situation will for example be able to be the following combination: town driving in daytime in cloudy weather. The situations can also characterize intermediate states or degrees of variations of these simple combinations, such as, for example light rain/heavy rain, dawn/twilight, etc.

"Advantageously and according to the invention, the device is suitable for determining the situation from data recovered out of the following data: the atmospheric conditions, the road environment, the environment of the driver;

"this list being neither limiting nor exhaustive, numerous other data being able to be used.

"According to this aspect of the invention, the device uses one or more of these information items to determine the situation in which the vehicle is located. For example, and in conjunction with the example of the preceding paragraph, driving in daytime in a town in cloudy weather will be determined by virtue of the geolocation data for town driving, by virtue of the time band data for daytime driving and by virtue of the weather conditions data for the cloudy weather. All of these data therefore make it possible to determine a situation.

"Advantageously and according to the invention, the device is configured to assign a weight to all or part of the recovered data as a function of the situation of the vehicle and to weight the data by their corresponding weight in the computation of the transmission coefficient.

"According to this aspect of the invention, the assignment of weights to the recovered data as a function of the determined situation of the vehicle allows for a computation of the transmission coefficient taking into account the weight of the data and therefore allowing for a computation of the transmission coefficient best suited to the determined situation. In effect, as a function of the determined situation, some data have more importance in the computation of the transmission coefficient.

"Advantageously and according to the invention, a first of the sensors is a sensor configured to measure a brightness in the axis of the vehicle and a second of the sensors is a sensor configured to measure a brightness in another direction, the device being configured to take account of the orientation of the head of the driver and perform the computation as a function of the data recorded by the first and the second sensors and as a function of the orientation of the head.

"According to this aspect of the invention, the device comprises, among its sensors, at least two brightness sensors, one being configured to measure the brightness in the axis of the vehicle so as, for example, to detect a glare provoked by the lighting of an oncoming vehicle. The device takes into account the orientation of the gaze of the driver and weights the brightness data recorded by the two sensors accordingly: for example, if the driver is looking in a direction corresponding to the axis of the vehicle, the data from the sensor directed in this axis will be predominant over the data originating from the second sensor in the computation of the transmission coefficient of the screen with variable transmission. On the other hand if the driver is looking mainly in the direction of the second sensor, the data from the latter will be predominant in the computation of the transmission coefficient of the screen with variable transmission. Between these two directions, the device will be able to assign intermediate weights to the data according to the orientation of the gaze of the driver.

"Advantageously and according to the invention, the screen with variable transmission comprises spectacles and the second sensor is situated on the spectacles.

"According to this aspect of the invention, the second sensor is situated as close as possible to the eyes of the driver and therefore give accurate information on the brightness which reaches him or her. Thus, for example, if the driver looks in a direction other than the axis of the vehicle, the data from the second sensor will be predominant in the computation of the transmission coefficient: these data are those received as close as possible to the view of the driver, and therefore enable him or her for example to keep a clear view if he or she looks to the side, to check for example for the presence of a pedestrian crossing the road, a traffic light or else a vehicle coming from an intersection.

"Advantageously and according to the invention, the device comprises a pulsed lighting, the device being configured to drive the pulsed lighting, in a first mode in synchronism with the transmission coefficient, and, in a second mode, independently of the coefficient.

"The invention relates also to a method for assisting in the driving of a motor vehicle, the vehicle being equipped with a screen with variable transmission intended to be arranged between a road scene in front of the vehicle and a driver of the vehicle, the method comprising a step of recovery of data representative of the environment in which the vehicle is located, and a step of driving a transmission coefficient of the screen with variable transmission, wherein the method comprises a step of taking into account of the data recovered in the recovery piece of step and a step of computation of the transmission coefficient by combination of the data.

"A method according to the invention therefore makes it possible to rely on a number of types of data to make it possible to adjust the transmission coefficient by combination of these data, and not take into account only a single recovered piece of data.

"Advantageously and according to the invention, the data representative of the environment are chosen from one or more of the following types of data: The atmospheric conditions such as: rain, wind, snow, mist, etc. . . . the time of day etc. . . . The road environment such as the state of the ground, the glare from another vehicle or from a fixed light source, the nature of the road (bend, tunnel, highway, etc. . . .), the geolocation, the speed of the vehicle, etc. . . . The environment of the driver such as: the orientation of his or her head, the orientation of his or her gaze, etc. . . .

"this list being neither limiting nor exhaustive, numerous other data being able to be used.

"Advantageously and according to the invention, the method comprises a step of determination of a situation in which the vehicle is located from the recovered data.

"Advantageously and according to the invention, the step of determination of the situation is performed on the basis of the data recovered out of the following data: the atmospheric conditions, the road environment, the environment of the driver;

"this list being neither limiting nor exhaustive, numerous other data being able to be used.

"Advantageously and according to the invention, the method comprises a step of assignment of a weight to all or part of the recovered data as a function of the situation of the vehicle and in that it comprises a step of weighting of the data by their corresponding weight for the computation of the transmission coefficient.

"Advantageously and according to the invention, the method comprises a step of recovery of brightness data in the axis of the vehicle and in another direction and a step of detection of the orientation of the head of the driver. Furthermore, the computation step is performed by taking into account the brightness data as a function of the orientation of the head.

"Advantageously and according to the invention, the method comprises a first step driving a pulsed lighting of the vehicle, in synchronism with the driving of the transmission coefficient, and a second step of driving the lighting independently of the latter driving of the transmission coefficient.

"These and other objects and advantages of the invention will be apparent from the following description, the accompanying drawings and the appended claims."
