  • Patent number: 11420633
    Abstract: A driving assistance method for a motor vehicle (1) when approaching a speed bump comprises, according to the invention: detecting and tracking at least one other moving vehicle (41) in front of the motor vehicle (1) based on processing images captured by a camera (10) on board the motor vehicle (1); establishing a temporal profile of the estimated distance between the motor vehicle (1) and the at least one detected and followed other moving vehicle (41); detecting an anomaly area in the temporal profile; and estimating a distance dbump between the motor vehicle (1) and a speed bump (3) on the basis of the estimated distance between the motor vehicle (1) and the at least one other vehicle (41) at a time separate from the times corresponding to the detected anomaly area.

  • Patent number: 11052912
    Abstract: The invention relates to a driver-assistance device for assisting with driving a motor vehicle (1) following a road (2), this device comprising: a sensor suitable for acquiring a signal representative of the presence of an obstacle in the interior of a detection field (110) 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 (20) 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.

  • Patent number: 10916133
    Abstract: The invention relates to a method for determining an optimum speed (VOPT) to be adopted by a motor vehicle (1) when said motor vehicle (1) is approaching a traffic light (2). According to said method a first GLOSA-type on-board system (10) determines, upon receiving a message emitted by said traffic light (2), a total distance (DTL) of travel separating the motor vehicle (1) from the traffic light (2), then estimates the time necessary for the motor vehicle (1) to travel said total distance (DTL), and finally defines a recommended speed (VQ) based on the status of the traffic light (2) at the end of the estimated time. The method is characterised in that it also uses at least one speed limitation produced via a second system (12; 13) on board said motor vehicle such as to determine said recommended speed (VQ) and/or said optimum speed (VQPT).

  • Publication number: 20190263410
    Abstract: The present invention refers to a driver support method for an ego vehicle (10), wherein the ego vehicle (10) travels on an ego lane (14) and wherein next to the ego lane (14), an emergency lane (18) is provided, the method comprising the steps of: a) Monitoring the emergency lane (18); b) Determining, if a vehicle (20) is present on the emergency lane (18) in front of the ego vehicle (10); and c) before the ego vehicle (10) passes the vehicle (20) located on the emergency lane (18), performing at least one of c1) changing the lateral position of the ego vehicle (10) in order to increase the lateral distance to the emergency lane (18); and c2) decreasing the speed of the ego vehicle (10).
