Abstract
A method is provided for projecting a guide line onto a road surface. An anticipated trajectory of the motor vehicle is calculated from the speed and steering angle of the motor vehicle. A guide line is projected onto a road surface in front of the motor vehicle. The guide line indicates the anticipated travel path. Whether the motor vehicle is starting a curve is detected based on the steering angle. The guide line contains the shape of a first clothoid in at least a first segment when it is detected that the motor vehicle is starting to travel in a curve.
Claims15
A method for projecting a guide line onto a road surface, the method comprising:
- calculating an anticipated trajectory of a motor vehicle from a speed and a steering angle of the motor vehicle;
- projecting the guide line onto the road surface in front of the motor vehicle, wherein the guide line indicates the anticipated trajectory;
- and
- detecting that the motor vehicle is starting to travel in a curved path when the steering angle exceeds a threshold value;
- wherein the guide line contains a shape of a first clothoid in at least a first segment upon detecting that the motor vehicle is starting to travel in the curved path.
