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 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 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: The invention relates to a regulation speed display apparatus of a vehicle. The apparatus causes a display device to display a detected regulation speed as a standard regulation speed when a traffic sign in a shot landscape is not a traffic sign with an auxiliary sign. The apparatus causes the display device to display the detected regulation speed as the standard regulation speed when the traffic sign in the shot landscape is the traffic sign with the auxiliary sign and the detected regulation speed is larger than an already displayed standard regulation speed. The apparatus causes the display device to maintain the display of the already displayed standard regulation speed when the traffic sign in the shot landscape is the traffic sign with the auxiliary sign and the detected regulation speed is equal to or smaller than the already displayed standard regulation speed.

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 driving support device detects a speed limit by imaging a speed sign indicating the speed limit of a traveling lane. Also, the driving support device continuously acquires attribute information from a car navigation system. The speed limit recognized from a road sign is displayed on a screen mounted in a vehicle. When the speed limit recognized from the road sign is not equal to a speed limit acquired from the car navigation system, a display time of the speed limit is limited. When the attribute information is changed, display of the speed limit is stopped.

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.
