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.
Claims10
A method for controlling a lateral position of a vehicle on a traffic lane, the method comprising:
- during a first period:
- automatically controlling the lateral position of the vehicle within the traffic lane to follow a first reference trajectory, and
- monitoring, while automatically controlling the lateral position of the vehicle within the traffic lane to follow the first reference trajectory, a lateral distance separating the vehicle from an edge of the traffic lane, and alerting a driver of the vehicle when the lateral distance separating the vehicle from the edge of the traffic lane is less than or equal to a first threshold;
- then
- detecting a command applied to a steering wheel of the vehicle by a driver for shifting the vehicle toward an edge of the traffic lane;
- then
- stopping the first period;
- and
- during a second period:
- automatically controlling the lateral position of the vehicle within the traffic lane to follow a second reference trajectory, the second reference trajectory being determined according to the command applied to the steering wheel by the driver, and
- monitoring, while automatically controlling the lateral position of the vehicle within the traffic lane to follow the second reference trajectory, the lateral distance separating the vehicle from an edge of the traffic lane, and alerting the driver when the lateral distance separating the vehicle from the edge of the traffic lane is less than or equal to a second threshold, the second threshold being less than the first threshold.
