Abstract
A lane localization system and method that may include a first measurement distance sensor located on a right-hand side of a vehicle and a second measurement distance sensor located on a left-hand side of the vehicle. The system and method may also be operable to receive data from at least one of the first measurement distance sensor or the second measurement distance sensor. The system and method may further determine which lane along a road the vehicle is traveling within based on a comparison a frequency of one or more echoes indicative of one or more objects located on the right-hand side and the left-hand side of the vehicle.
Claims20
A lane localization system, comprising:
- a first measurement distance sensor located on a right-hand side of a vehicle and a second measurement distance sensor located on a left-hand side of the vehicle;
- a processor operable to:
- receive measurement data from at least one of the first measurement distance sensor or the second measurement distance sensor;
- detect one or more objects on the right-hand side of the vehicle or the left-hand side of the vehicle using the measurement data;
- generate one or more echo frequency response signals based on the measurement data and the one or more objects;
- and
- compare the one or more echo frequency response signals to determine which lane along at least a two-lane road the vehicle is traveling.
A lane localization method, comprising:
- receiving measurement data from at least one of a first measurement distance sensor located on a right-hand side of a vehicle or a second measurement distance sensor located on a left-hand side of the vehicle;
- detecting one or more objects on the right-hand side of the vehicle or the left-hand side of the vehicle using the measurement data;
- generating one or more echo frequency response signals based on the measurement data and the one or more objects;
- and
- comparing the one or more echo frequency response signals to determine which lane along at least a two-lane road the vehicle is traveling.
A non-transitory computer-readable medium operable to employ a lane localization system, the non-transitory computer-readable medium having computer-readable instructions stored thereon that are operable to be executed to perform the following functions:
- receive measurement data from at least one of a first measurement distance sensor located on a right-hand side of a vehicle or a second measurement distance sensor located on a left-hand side of the vehicle;
- detect one or more objects on the right-hand side of the vehicle or the left-hand side of the vehicle using the measurement data;
- generate one or more echo frequency response signals based on the measurement data and the one or more objects;
- and
- compare the one or more echo frequency response signals to determine which lane along at least a two-lane road the vehicle is traveling.
