Abstract
A method is described for assisting a driver when operating a vehicle on a road having a road surface and lane markings. The method includes the steps of ascertaining position of lane markings using an ascertaining apparatus, determining at least one lane delimiting line on the ascertained position of the lane markings, specifying a trajectory of the vehicle, in the event of the trajectory that is specified intersecting a lane delimiting line that is determined, outputting an instruction to the driver of the vehicle using at least one light beam that is projected onto the road surface.
Claims17
A method for assisting a driver when operating a vehicle, comprising:
- ascertaining positions of lane markings on a road using an ascertaining apparatus;
- determining a lane delimiting line based on the position of the lane markings;
- specifying a trajectory of the vehicle;
- and
- if the trajectory intersects the lane delimiting line, outputting an instruction to the driver of the vehicle using at least one light beam generated by at least one headlight of the vehicle projected onto a surface of the road, wherein the instruction is output in the form of a sweeping movement of the at least one light beam that is projected onto the surface of the road.
A driver assist apparatus for a vehicle, comprising:
- an ascertaining apparatus ascertaining positions of lane markings on a road surface;
- a controller determining a lane delimiting line based on the position of the lane markings, specifying a trajectory of the vehicle, and establishing whether the trajectory intersects the lane delimiting line;
- and
- a headlight of the vehicle comprising a light source projecting a light beam onto the road surface to provide an instruction to a driver of the vehicle if the trajectory intersects the lane delimiting line, wherein the instruction is output in the form of a sweeping movement of the light beam that is projected onto the road surface.
A vehicle comprising:
- an ascertaining apparatus ascertaining positions of lane markings on a road surface;
- a controller determining a lane delimiting line based on the position of the lane markings, specifying a vehicle trajectory, and establishing whether the trajectory intersects the lane delimiting line;
- and
- at least one headlight of the vehicle comprising a light source projecting a light beam onto the road surface as an instruction to a driver of the vehicle if the specified trajectory intersects the determined lane delimiting line, wherein the instruction is output in the form of a sweeping movement of the light beam that is projected onto the road surface.
