Abstract
A method includes identifying a reference target with both a vehicle sensor and an infrastructure position signal. A position of a host vehicle with respect to the reference target is then determined. A localized position error between the host vehicle position and the determined position with respect to the object is then calculated with a vehicle controller. Finally, a vehicle positioning system is compensated to account for the localized position error.
Claims20
A method comprising:
- identifying a reference target with both a vehicle sensor and an infrastructure position signal;
- determining a position of a host vehicle with respect to the reference target;
- calculating a localized position error between the host vehicle position and the determined position with respect to the reference target with a vehicle controller;
- and
- compensating a vehicle positioning system to account for the localized position error.
2 more elements
A vehicle positioning system, comprising:
- a first computing device configured to receive dynamics data and sensor object data from a host vehicle;
- a receiving device configured to receive real time object position data from a reference target;
- and
- a second computing device configured to compare data from the first computing device and the receiving device and to run an error function, wherein the second computing device is configured to calibrate the vehicle positioning system when the error function has a value other than zero.
1 more element
A method comprising:
- identifying a reference target with both a vehicle sensor and an infrastructure position signal;
- determining, with a vehicle controller, that the vehicle sensor and the infrastructure position signal are identifying the same reference target;
- calculating, in the vehicle controller, a localized position error between the host vehicle position and the localized position determined using the reference target based on at least data received from the vehicle sensor and the infrastructure position signal;
- and
- compensating a vehicle positioning system to account for the localized position error.
