Classification: CPC B  G | IPC B  G

Claim 0:
1. A vehicle control system comprising:
a first sensor and a second sensor that detect an object around a vehicle;
an information integration device that groups first detection information and second detection information that are detection results of the first sensor and the second sensor that detect the object and outputs integrated detection information; and
a vehicle control device that controls the vehicle based on the integrated detection information,
wherein the information integration device includes an arithmetic device and a storage device, and
the arithmetic device stores first time-series information that is time-series information of the first detection information and second time-series information that is time-series information of the second detection information in the storage device,
selects the first sensor to be a target for calculating a correction information,
groups the first time-series information and the second time-series information when a time average Mahalanobis distance of the first time-series and the second time-series satisfies a first threshold, to calculate a correction parameter of the first detection information,
calculates a reference time-series information of a reference pixel of the second sensor,
calculates an observation time-series information of an observation pixel of the first sensor,
calculates the correction information by correcting the first detection information using the correction parameter, the correction parameter determined by calculating an average of differences between the reference pixel in the reference time-series information and the observation pixel in the observation time-series information,
deletes first time-series and a second time-series before a predetermined time,
stores the correction parameter, and
outputs the integrated detection information by instantaneous value grouping using the correction information and the second detection information.
