Abstract: A drive assist device includes: an acquisition unit that acquires a captured image from an on-board camera; a recognition unit that recognizes road information of roads around a host vehicle on the basis of the captured image; a determination unit that determines, on the basis of the road information recognized by the recognition unit, a priority relation between a present road in which the host vehicle is running and an intersecting road that meets the present road; and an assist unit that executes, in response to the determination unit determining that the present road does not have priority over the intersecting road, drive assistance for the host vehicle when the host vehicle enters a place where the present road meets the intersecting road.

Abstract: An ECU as a driving assistance device has a traffic sign detection section, a lane entry detection section and a judgment section. The traffic sign detection section detects traffic signs including a speed limit symbol based on front-image data captured by an in-vehicle camera. The lane entry detection section detects that the own vehicle has entered a ramp lane to leave a highway. The judgment section detects an extent of a current driving lane as the ramp lane when following conditions (c1) and (c2) are satisfied after the lane entry detection section detects the entry of the own vehicle into the ramp lane: (c1) not less than two traffic signs are arranged along the current driving lane in forward direction of the vehicle; and (c2) an arrangement of speed limit symbols included in the detected traffic signs satisfy a predetermined speed reduction pattern.

Abstract: In an information processing system, a regulation recognizer recognizes regulatory information displayed on a first indicator disposed external to a subject vehicle from a captured image. A condition recognizer recognizes conditional information displayed on a second indicator disposed external to the vehicle from the captured image. The conditional information is indicative of a condition under which the regulation indicated by the regulatory information recognized by the regulation recognizer is to be applied, where the condition is an environmental condition about an environment around the vehicle. An output controller controls outputs generated by an output generator. If the environment around the vehicle recognized by the environment recognizer satisfies the environmental condition indicated by the conditional information recognized by the condition recognizer, the output controller controls the output generator based on the regulatory information recognized by the regulation recognizer.

Abstract: In a driving assistance apparatus, a start determiner determines whether or not during travel in a no-passing zone an own vehicle has laterally moved from a rearward position to a lateral position relative to the preceding vehicle, and if the own vehicle has laterally moved, then determine that the own vehicle has started passing driving. If the own vehicle has started passing driving in the no-passing zone, an alert controller starts alerting using an alert device at a start of passing driving. A situation determiner determines whether or not a change of situation from a blocking situation to a non blocking situation has occurred after the start of passing driving. If the change of situation from the blocking situation to the non blocking situation has occurred, an alerting stopper stops alerting using the alert device.

Abstract: In an information processing device mounted on a vehicle, a sign recognition section detects a traffic sign from image data captured by and transmitted from an in-vehicle camera. A judgment section detects a direction to a prohibited roadway/lane based on the detected traffic sign. To the prohibited roadway/lane the vehicle is prohibited from approaching and entering. An operation detection section predicts, as a predicted driver's operation, whether or not the driver intends to move the vehicle in the detected direction to the prohibited roadway/lane. A warning control section instructs a display and an audio speaker to provide warning information to the driver when the predicted driver's operation indicates that the driver intends to move the own vehicle toward the detected direction to the prohibited roadway/lane.

Abstract: In a vehicle driving assistance apparatus, an initial action determiner determines the presence or absence of an initial action taken to start laterally moving, and a lateral movement determiner determines whether or not the own vehicle has laterally moved from a rearward position to a lateral position relative to a preceding vehicle. If the own vehicle has laterally moved after the initial action, based on at least one of a lateral distance between the own vehicle and the preceding vehicle and a relative speed of the own vehicle with respect to the preceding vehicle, a passing driving state determiner determines whether or not the own vehicle is in a passing driving state enabling the own vehicle to pass the preceding vehicle. If it is determined that the own vehicle is in the passing driving state, the own vehicle is likely to pass the preceding vehicle.

Abstract: A driving assistance apparatus includes a sign recognizing unit, a notification executing unit, and a lane change determining unit. The sign recognizing unit recognizes a traffic sign from an image captured by an on-board imaging apparatus. The notification executing unit notifies a driver of information indicated by the traffic sign recognized by the sign recognizing unit. The lane change determining unit determines whether or not an own vehicle is making a lane change. If the lane change determining unit determines that the own vehicle is making a lane change while traveling on a road in which different traffic signs are provided among traffic lanes, the notification executing unit notifies the driver of destination lane information that is information for a traffic lane to which the own vehicle is moving.

Abstract: A driving assistance apparatus includes a sign recognizing unit and a notification executing unit. The sign recognizing unit recognizes a traffic sign from an image captured by an on-board imaging apparatus. The notification executing unit notifies a driver of sign information that is information indicated by the traffic sign recognized by the sign recognizing unit. Based on a vehicle speed of the own vehicle and operating information of a turn indicator of the own vehicle under a condition that the driver is being notified of the sign information, the notification executing unit stops notifying the driver of the sign information.

Abstract: A unit setting apparatus sets a unit of distance used in a vehicle. A unit is set, which is indicated by map unit information, as a unit to be used, when a map unit acquisition section has acquired the map unit information. A unit is set, which is indicated by operation unit information, as a unit to be used, when the map unit acquisition section has not acquired the map unit information, and an operation unit acquisition section has acquired operation unit information. A unit is set, which is indicated by sign unit information, as a unit to be used, when the map unit acquisition section has not acquired the map unit information, the operation unit acquisition section has not acquired the operation unit information, and a sign unit acquisition section has acquired the sign unit information.

Abstract: A vehicle behavior detection device mounted on an own vehicle detects own vehicle's behavior, in particular driver's right or left turn behavior at an intersection on a roadway. The vehicle behavior detection device is a microcomputer system having a CPU capable of providing an intended direction acquiring section, a turn direction acquiring section, a coincidence judgment section and an information output section. The intended direction acquiring section obtains an intended direction toward which the own vehicle is turning. The turn direction acquiring section acquires a direction to which the own vehicle turns. The coincidence judgment section detects whether or not the intended direction coincides with the turn direction of the own vehicle. The information output section provides warning regarding wide right or left turn of the own vehicle when the judgment result indicates that the intended direction does not coincide with the turn direction of the own vehicle.

Abstract: In a driving assistance apparatus, a start determiner determines whether or not during travel in a no-passing zone an own vehicle has laterally moved from a rearward position to a lateral position relative to the preceding vehicle, and if the own vehicle has laterally moved, then determine that the own vehicle has started passing driving. If the own vehicle has started passing driving in the no-passing zone, an alert controller starts alerting using an alert device at a start of passing driving. A situation determiner determines whether or not a change of situation from a blocking situation to a non blocking situation has occurred after the start of passing driving. If the change of situation from the blocking situation to the non blocking situation has occurred, an alerting stopper stops alerting using the alert device.

Abstract: An information processing device has a display control section and a state detection section. The display control section instructs a display device to display road information regarding a roadway on which a vehicle runs. The display device is arranged inside of the vehicle. The state detection section detects at least one of cases A and B. In the case A, it is detected whether or not the vehicle is in a first state as a roundabout entry motion estimation in which the vehicle will enter a roundabout. In the case B, it is detected whether or not the own vehicle is in a second state in which the own vehicle is running on the roundabout. The display control section reduces information's visibility to the driver displayed on the display device when the state detection section detects at least one of the first state and the second state.

Abstract: An entry detection apparatus includes a position detection unit that detects presence of an entry prohibited road ahead of a vehicle based on a position of the vehicle and map data including information showing, for each road section, whether the road section is an entry prohibited road section, a sign detection unit that detects whether or not a pair of no-entry signs are present on both sides of a running course of the vehicle based on an image captured by an image sensor mounted on the vehicle, and determines whether or not the vehicle has passed between the no-entry signs, and an entry determination unit that determines that the vehicle has entered the entry prohibited road if the position detection unit detects presence of the entry prohibited road, and the sign detection unit determines that the vehicle has passed between the no-entry signs.

Abstract: In a device to detect a drive country in which a subject vehicle is located, a control section acquires correspondence information which shows a relationship between traffic signs and a degree of installation reliability of a traffic sign in each country as a drive country candidate in which the subject vehicle is located. The degree of installation reliability of each traffic sign indicates a degree of installation reliability located in each country. The control section acquires matching information which represents whether a traffic sign located around the subject vehicle matches the traffic sign stored in the correspondence information.
