Abstract
A method and apparatus for determining a route of a vehicle are provided. The method includes activating fail operative steering in response to detecting an electronic power steering (EPS) failure, determining a length of a lane map fusion ring, calculating a desired route based on a line of the lane map fusion ring if the determined length is greater than a first predetermined distance, and calculating desired route based on offset information and heading information of the lane map fusion ring and curvature information and curvature derivative information calculated from map data if the determined length is less than the first predetermined distance.
Claims20
A method for determining a route of a vehicle, the method comprising:
- activating fail operative steering in response to detecting an electronic power steering (EPS) failure;
- determining a length of a lane map fusion ring;
- calculating a desired route based on a line of the lane map fusion ring if the determined length is greater than a first predetermined distance;
- and
- calculating the desired route based on offset information and heading information of the lane map fusion ring and curvature information and curvature derivative information calculated from map data, if the determined length is less than the first predetermined distance.
An apparatus that determines a route, the apparatus comprising:
- at least one memory comprising computer executable instructions;
- and
- at least one processor configured to read and execute the computer executable instructions, the computer executable instructions causing the at least one processor to:
- activate fail operative steering in response to detecting an electronic power steering (EPS) failure;
- determine a length of a lane map fusion ring;
- calculate a desired route based on a line of lane map fusion ring if the determined length is greater than a first predetermined distance;
- and
- calculate the desired route based on offset information and heading information of lane map fusion ring and curvature information and curvature derivative information calculated from map data, if the determined length is less than the first predetermined distance.
