  • Lane keep assistance based on rate of departure
    Patent number: 11772648
    Abstract: A lane keep assist system for a vehicle includes a controller that receives first and second signals including values for a distance from a point on the vehicle to an edge of a lane marker for the vehicle's lane of travel at first and second times. The controller determines a rate of change in the distance responsive to the first and second signals and generates a power steering system control signal responsive to the rate of change. The control signal generates a force on a steering gear of the vehicle connected to one or more steerable wheels on the vehicle to control the position of the vehicle relative to the lane of travel with the amount of the force responsive to the rate of change.
