Abstract: A method for controlling the lateral position of a vehicle on a traffic lane includes: a first controlling of the vehicle following a first reference trajectory, alerting the driver if the lateral distance separating the vehicle from the edge of the traffic lane is less than a first threshold, then detecting a command applied to a steering wheel of the vehicle, then a second controlling of the vehicle following a second reference trajectory, the second trajectory being determined depending on the command applied to the steering wheel, and alerting the driver if the lateral distance separating the vehicle from the edge of the traffic lane is less than a second threshold, the second threshold being less than the first threshold.

Abstract: A method for detecting an exit lane for a motor vehicle includes: detecting, in images acquired by an onboard camera, marking lines on the ground on the right and on the left laterally delimiting the main traffic lane, determining first and second heading angles with respect to the detected marking lines, providing a first, standard exit lane detection state, based on the comparison of the first and second heading angles with a predetermined threshold, and providing a second, coaxial exit lane detection state, based on the comparison between the derivatives with respect to time of the variation of the first and second heading angles and of the verification that the value of the first or the second heading angle remains substantially close to a zero value.

Abstract: A driving assistance module for a motor vehicle includes a main block that receives, at input, a set of input data relating to the motor vehicle and to its environment, and that provides, at output, a preliminary control for the motor vehicle on the basis of the input data, and a safeguarding block for safeguarding the preliminary control setpoint, which safeguarding block is separate from the main block and receives, at input, the preliminary control setpoint and a set of check data, provides, at output, a final control setpoint and checks that the preliminary control setpoint is in accordance with a set of at least one predefined rule. The set of check data differs from the set of input data, and each of the check data has a safety level strictly higher than a safety level of at least one of the input data.

Abstract: A method is for detecting the route taken by a motor vehicle in a particular zone within which the number of lanes increases or decreases.

Abstract: A method for calculating a lateral position of an ego motor vehicle on a traffic lane includes calculating a first theoretical lateral position of the ego vehicle, calculating a second theoretical lateral position of the ego vehicle, calculating a third theoretical lateral position of the ego vehicle, calculating the lateral position of the ego vehicle using a weighted average of the first lateral position, the second lateral position, and the third lateral position.

Abstract: A method for controlling in real time the path of a motor vehicle travelling in a traffic lane includes detecting a corner in the traffic lane, then, when the vehicle enters the corner, determining first and second quantities for a plurality of successive sampling increments, based on state variables characteristic of the movement of the vehicle, determining a first stored value dependent on the first quantity determined in the current sampling increment and one of the preceding sampling increments, determining a second stored value dependent on the second quantity determined in the current sampling increment and one of the preceding sampling increments, saving the first and second stored values determined for each sampling increment, then, when the vehicle exits the corner determining a value of the understeer gradient depending on the saved first and second stored values, and determining a command for the vehicle based on the understeer gradient.

Abstract: A control method is provided for controlling a lateral position of a motor vehicle. The control method includes calculating a sighting distance of a detector means embedded in the vehicle, calculating a first component of a steering angle setpoint of a steered wheels of the vehicle, and calculating a second component of the steering angle setpoint. The first component is an open loop component of a control system, while the second component is a closed loop component of the control system. The first component is weighted by a gain that is a decreasing function of the sighting distance.
