Abstract
A system for monitoring a position of a vehicle in a lane of a road, the system comprising: a processor; a first camera configured to output first image data relating to a surface of the road on a first side of the vehicle; a second camera configured to output second image data relating to a surface of the road on a second side of the vehicle, wherein the processor is configured to determine if the vehicle is at risk of straying outside the lane based on the first image data or the second image data and auxiliary data received by the processor.
Claims18
A system for monitoring a position of a vehicle in a lane of a road, the system comprising:
- a processor;
- a first camera configured to output first image data relating to a surface of the road on a first side of the vehicle;
- a second camera configured to output second image data relating to a surface of the road on a second side of the vehicle,
- wherein the processor is configured to:
- receive auxiliary data indicating whether or not the vehicle is approaching a turn or obstacle in the road;
- infer, estimate or determine the position of the vehicle relative to a lane marking that delimits a boundary of the lane detected in the image data from one or more of the cameras;
- determine a value representative of a distance between the vehicle and the lane marking based on the first or second image data;
- compare the value to a threshold;
- output a control signal to one or more of:
- a driver warning system;
- a brake control subsystem;
- a throttle control subsystem;
- and a steering control subsystem when it is determined that the vehicle is at risk of straying outside the lane and the value is equal to or less than the threshold;
- and
- defer outputting the control signal when it is determined that the vehicle is at risk of straying outside the lane and the value is greater than the threshold.
A vehicle comprising a system for monitoring a position of the vehicle in a lane of a road, wherein the system comprises:
- a processor;
- a first camera positioned on a first side of the vehicle in a downward-facing orientation to provide first image data relating to a surface of the road on the first side of the vehicle;
- a second camera positioned on a second side of the vehicle in a downward-facing orientation to provide second image data relating to a surface of the road on a second side of the vehicle,
- wherein the processor is configured to:
- determine if the vehicle is at risk of straying outside the lane based on the first image data or the second image data and auxiliary data received by the processor;
- determine a value representative of a distance between the vehicle and a lane marking that delimits a boundary of the lane based on the first or second image data;
- compare the value to a threshold;
- output a control signal to one or more of a driver warning system;
- a brake control subsystem:
- a throttle control subsystem;
- and a steering control subsystem when it is determined that the vehicle is at risk of straying outside the lane and the value is equal to or less than the threshold;
- and
- defer outputting the control signal when it is determined that the vehicle is at risk of straying outside the lane and the value is greater than the threshold.
