A tracking control apparatus for tracking a preceding vehicle includes information acquiring unit for acquiring information about surrounding the own vehicle, preceding vehicle determining unit for determining the preceding vehicle running ahead of the own vehicle, control unit controls the tracking control to be maintained or released, and turn signal determining unit for determining whether or not a turn signal of a turn signal unit of the preceding vehicle is active. The control unit maintains or releases the tracking control by determining the surrounding of the own vehicle concerning a traffic lane change by the preceding vehicle based on the information acquired by the information acquiring unit, when the turn signal determining unit determines that the turn signal of the turn signal unit is active.

On-vehicle tracking control apparatus

A vehicle driving assistance apparatus mounted in a vehicle. In the apparatus, a drivable route detection unit detects a drivable route, a vehicle state quantity detection unit detects state quantities of the vehicle, and a steering control unit controls steering of the vehicle. Further, in the apparatus, an allowable region estimation unit estimates a driving allowable region on the basis of the detected state quantities and a predetermined allowable range of behavior of the vehicle. A deviation determination unit determines that the vehicle will deviate from the drivable route when a minimum width of an overlap region of the drivable route and the driving allowable region is less than a predetermined threshold. An intervention instruction unit then outputs to the steering control unit an intervention control signal to control steering of the vehicle.

Vehicle driving assistance apparatus

A vehicle control apparatus capable of automatic steering control while reducing discomfort or stress on vehicle occupants. In the apparatus, a lane detection unit detects a lane in which the vehicle is traveling. An offset setting unit sets an offset within the lane suitable for making a driver feel less stressed. An occupant detection unit detects the presence of a designated occupant of a seat opposite a driver's seat. An offset adjustment unit, when the designated occupant is detected, adjusts the offset set by the offset setting unit to be decreased. A vehicle-path estimation unit estimates a vehicle path in the lane such that the vehicle can travel along the vehicle path from a current lateral position to a target lateral position of the vehicle. An automatic steering control unit automatically controls steering so that the vehicle travels along the estimated vehicle.

Vehicle control apparatus

An inter-vehicle distance control device is provided. In this control device, an inter-vehicle distance detecting section detects an inter-vehicle distance between an own vehicle and a preceding vehicle traveling in front of the own vehicle. A laterally adjacent vehicle detecting section detects another vehicle present beside the own vehicle. A cut-in detecting section judges whether or not a cut-in by the other vehicle detected by the laterally adjacent vehicle detecting section is likely to occur, before the other vehicle cuts in between the own vehicle and the preceding vehicle. An inter-vehicle distance adjusting section performs an inter-vehicle distance extension adjustment to increase the inter-vehicle distance when the cut-in detecting section judges that a cut-in is likely to occur. An inter-vehicle distance control section controls the inter-vehicle distance based on information from the inter-vehicle distance adjusting section.

A driving control apparatus mounted on a present vehicle used for tracking a preceding vehicle includes: control module for controlling the present vehicle to accelerate or decelerate; vehicle detecting module for detecting the preceding vehicle; region detecting module for detecting a lateral region existing on an adjacent lane being adjacent to a present lane where the present vehicle exists, the lateral region being laterally to the present vehicle; and region determining module for determining whether or not the lateral region is an avoidance region that has a predetermined area. The control module performs an avoidance standby operation that allows the present vehicle to accelerate or decelerate based on a result of determining by the region determining module, when the vehicle detecting module detects the preceding vehicle existing on the present lane.

Driving control apparatus mounted on vehicle to avoid collision with preceding vehicle

A vehicle control apparatus that for automatic steering control that reduces occupant discomfort and stress is provided. A lane width of a subject lane and a current in-lane ratio are detected. If an off-lane obstacle which may place stress on the occupant is present within a prescribed area, a relative position between each off-lane obstacle and the vehicle is determined. A target in-lane ratio is determined based on the relative position. Specifically, when the off-lane obstacles are present on both the left and right sides of the subject lane, the target in-lane ratio is such that lateral distances to both off-lane obstacles are equal. When the off-lane obstacle is present on only one of either the left or right of the subject lane, the target in-lane ratio is set such that a lateral position away from the off-lane obstacle by a lateral distance set in advance is the target lateral position.

A driving assistance apparatus mounted to a vehicle is disclosed. The apparatus determines whether an amount of change in tire wheel speed of each tire wheel of the vehicle exceeds a threshold. The apparatus specifies a tire wheel crossing order, which is an order in which the tire wheels of the vehicle cross over a level difference between a road and a parking lot when the vehicle crosses over the level difference. The apparatus determines whether or not the vehicle has crossed over the level difference between the road and the parking lot, based on whether a threshold-exceeding order is identical to the specified tire wheel crossing order. The threshold-exceeding order is an order in which the amounts of change in the tire wheel speed of the respective tire wheels exceed the threshold.
