Abstract
A drive assistance system includes an onboard device that is mounted on a vehicle performing automatic driving based on sensing information detected by a sensor of the vehicle, and a center that communicates with the onboard device. The onboard device includes a sensing information acquisition portion that acquires the sensing information. Either the onboard device or the center includes an evaluation portion that evaluates a detection performance of the sensor based on the sensing information. The center includes a region specification portion that specifies a decrease region where the detection performance of the sensor decreases, the decrease region specified by the detection performance, based on the sensing information, and the decrease region specified by a position at which the sensing information has been detected. The onboard device stops the automatic driving when the vehicle is located in the decrease region.
