Abstract
Methods and systems for providing driving assistance in a vehicle. In one embodiment, a method includes: determining, by a processor, curvature data associated with a roadway ahead of the vehicle; determining, by the processor, velocity data based on the curvature data, steering data of the vehicle, and set speed data associated with a semi-autonomous control system of the vehicle; and generating, by the processor, control commands to the semi-autonomous control system to control the vehicle to a speed other than a set speed of the set speed data based on the velocity data.
Claims20
A method for providing driving assistance in a vehicle, comprising:
- determining, by a processor, curvature data associated with a roadway ahead of the vehicle;
- determining, by the processor, velocity data based on the curvature data, steering data of the vehicle, and set speed data associated with a semi-autonomous control system of the vehicle;
- and
- generating, by the processor, control commands to the semi-autonomous control system to control the vehicle to a speed other than a set speed of the set speed data based on the velocity data.
A system in a vehicle for providing driving assistance, comprising:
- a controller including non-transitory computer readable media and configured to, by a processor:
- determine curvature data associated with a roadway ahead of the vehicle;
- determine velocity data based on the curvature data, steering data of the vehicle, and set speed data associated with a semi-autonomous control system of the vehicle;
- and
- generate control commands to the semi-autonomous control system to control the vehicle to a speed other than a set speed of the set speed data based on the velocity data.
A vehicle comprising:
- a sensor system configured to sense and environment of the vehicle;
- a semi-autonomous control system;
- and
- a controller for implementing a driver assistance system, the controller configured to:
- determine, by a processor, curvature data associated with a roadway ahead of the vehicle based on sensor data from the sensor system;
- determine, by the processor, velocity data based on the curvature data, steering data of the vehicle, and set speed data associated with the semi-autonomous control system;
- and
- generate, by the processor, control commands to the semi-autonomous control system to control the vehicle to a speed other than a set speed of the set speed data based on the velocity data.
