Abstract
An adaptive lane-keeping system for a commercial vehicle, including: an input module for entering sensor data from at least one sensor which is configured to detect the surroundings of the commercial vehicle; an evaluation module for evaluating the sensor data to determine a relative position of the commercial vehicle on a road; a lane-keeping module for controlling a steering system of the commercial vehicle based on a lane-keeping profile that defines a torque to be applied to a steering wheel of the commercial vehicle to support keeping in a lane; and a change module for changing the lane-keeping profile in response to a change in the detected environment. Also described is a related commercial vehicle, method, and computer readable medium.
Claims12
An adaptive lane-keeping system for a commercial vehicle, comprising:
- a non-transitory computer readable medium having a computer program, which is executable by a processor, including a program code arrangement having program code for adaptively keeping commercial vehicles in a lane, by performing the following:
- entering, via an input module, sensor data from at least one sensor which is configured to detect the surroundings of the commercial vehicle;
- evaluating, via an evaluation module, the sensor data and determining a position of the commercial vehicle on a road;
- controlling, via a lane-keeping module, a steering system of the commercial vehicle based on a lane-keeping profile that defines a torque to be applied to a steering wheel of the commercial vehicle to support keeping in a lane;
- and
- changing, via a change module, the lane-keeping profile for a change in the detected environment;
- wherein in a comparison, a desired torque of the driver is compared with a determined torque requirement, wherein the comparison determines whether the torque requirement determined by the system or the torque desired by the driver is greater, and wherein a resulting torque, obtained from the comparison, is provided to the steering system, wherein the steering system includes an adaptive steering system that processes adaptive object data and a resulting adapted toque is output to the steering system and leads to a change of direction of the vehicle.
