A driver-assistance method for a motor vehicle of interest, in which the vehicle of interest detects the third-party vehicles which are present at an initial instant in its environment is disclosed. During a first prediction cycle, an order of priority is assigned to the third-party vehicles which are detected at the initial instant and to the vehicle of interest, corresponding to an order in which the vehicles in the set follow one another in the travel zone starting from a vehicle detected in a position which is furthest ahead of the vehicle of interest. For each selected vehicle in the set, taken in the order of priority, another vehicle in the set is identified which is able to be a primary target vehicle for this selected vehicle. A manoeuvre which is in progress for the selected vehicle is estimated on the basis at least of the identified primary target vehicle.

Driver assistance for a motor vehicle

A driving assistance method for a motor vehicle () when approaching a speed bump comprises, according to the invention: detecting and tracking at least one other moving vehicle () in front of the motor vehicle () based on processing images captured by a camera () on board the motor vehicle (); establishing a temporal profile of the estimated distance between the motor vehicle () and the at least one detected and followed other moving vehicle (); detecting an anomaly area in the temporal profile; and estimating a distance dbetween the motor vehicle () and a speed bump () on the basis of the estimated distance between the motor vehicle () and the at least one other vehicle () at a time separate from the times corresponding to the detected anomaly area.

Assisting the driving of an automotive vehicle when approaching a speed breaker

A method for assisting in the driving of a vehicle on a fast road with carriageways separated by a safety rail in which the presence of the safety rail is detected is disclosed. The safety rail is modelled from measurements performed continuously by at least one laser scanner sensor mounted on the motor vehicle, with the determination of a confidence index associated with the detection by the laser scanner sensor, an automatic driving mode is activated when the confidence index Iis above a confidence threshold. This mode is maintained as long as a current confidence index associated with the detection is above the confidence threshold, and this mode is deactivated when the current confidence index passes below said confidence threshold. The density of traffic in front of the motor vehicle is estimated from images captured by an embedded camera.

Assistance in driving on a fast road with carriageways separated by a safety rail

A driving assistance functionality for a motor vehicle when approaching a tollgate is disclosed. The method involves a step (S) of calculating a probability of a tollgate being present based on at least two road context attributes that are determined from the motor vehicle and defining a road context ahead of said vehicle, said road context attributes being decorrelated from any concept of a tollgate. Examples of road context attributes: speed limit signs; marking lines on the ground; speed bumps or rumble strips on the ground; obstacles such as other vehicles; drivable space.

Driving assistance for a motor vehicle when approaching a tollgate

The invention relates to a driver-assistance device for assisting with driving a motor vehicle () following a road (), this device comprising: a sensor suitable for acquiring a signal representative of the presence of an obstacle in the interior of a detection field () of this sensor, and a control module that is programmed to control a driver-assistance function for assisting with driving the motor vehicle, depending on the signal acquired by said sensor, and: a) to detect, on the basis of a position of the motor vehicle and of characteristics of said road, a section () of this road located outside of the detection field of said sensor, and b) in case of detection of this road section, to control said driver-assistance function while taking into account the potential presence of an obstacle on said road section. An associated driver-assistance method is also described.

Device and method for assisting with driving a motor vehicle

An apparatus and corresponding methods for detecting a tailgating situation involving a second motor vehicle behind an automated vehicle, and performing an automated safety routine in response to the detected tailgating situation. The tailgating situation is detected based on a simultaneous occurrence of two or more conditions involving an estimated time to collision, lateral offsets of both vehicles with respect to a center of a lane, activation of a turn signal blinker of the second motor vehicle, or flashing of a headlamp of the second motor vehicle. The safety routine includes performing a lane change to an adjacent lane. When no adjacent lanes are available for a lane change, a maximum permissible deceleration rate is decreased while increasing a time gap between the automated vehicle and a third motor vehicle directly in front of the automated vehicle by automatically adjusting an amount of at least one of acceleration or braking.
