Abstract: An image recognizer is enabled to appropriately recognize a traffic signal applicable to an own vehicle. A traffic signal detector is configured to detect traffic signals based on an image of a front view of the own vehicle captured from the own vehicle. A calculator is configured to calculate a degree by which a front of the traffic signal faces the own vehicle based on the image. The traffic signal identifier is configured to identify a traffic signal applicable to the own vehicle based on the degree.

Abstract: A driving assistance system includes a driving assistance apparatus that updates map information based on travel trajectory information that is acquired from a measurement vehicle and provides the map information to a user vehicle that uses the map information. The driving assistance system includes a data storage unit and a map updating unit. The data storage unit stores therein, in time series, pieces of sign data that are related to a road sign and included in the travel trajectory information. The map updating unit updates the map information based on the pieces of sign data that are stored in the data storage unit. The map updating unit references the pieces of sign data that are stored in the data storage unit, identifies a change point in the pieces of sign data that are stored in time series, and updates the map information based on the change point.

Abstract: An evacuation running assistance system includes a peripheral environment recognizer to recognize at least a space of a road shoulder and a free space as a non-traffic portion, a time limit setter to set a time limit on the own vehicle for continuing evacuation running, and an evacuation place setter to determine at least one of the road shoulder space and the free space recognized by the peripheral environment recognizer as an evacuation place where the own vehicle is evacuated. A situation determiner determines a situation of an own vehicle as being in one of situations in which evacuation running is to be continued, running of an own vehicle is to be stopped on a lane, and road shoulder evacuation is to be performed based on the time limit. A controller controls the own vehicle based on the situation of the own vehicle determined by the situation determiner.

Abstract: An image recognition apparatus comprises an image information acquirer that acquires image information in a given cycle by capturing an image of a traveling path along which an own vehicle travels, a road sign recognizer that recognizes a road sign based on the image information and a traffic lane recognizer that recognizes traffic lanes located in the traveling path based on the image information. A memory is provided in the image recognition apparatus to store traffic lane information about a traffic lane recognized by the traffic lane recognizer in a time series. A determiner is also provided to determine if the road sign recognized by the road sign recognizer is for an own traffic lane by choosing a most suitable traffic lane among the traffic lanes recognized for a given period based on the traffic lane information stored in the time series.
