Abstract: A vehicle control apparatus performs traveling control of a vehicle based on a detection result of a radar apparatus that detects a target in the periphery of an own vehicle. The vehicle control apparatus calculates a shaft misalignment angle that is a misalignment amount of an attachment angle of the radar apparatus and a shaft misalignment direction, and sets a detection range over which a target to be subjected to traveling control of the own vehicle is detected. Until elapse of a predetermined initial period after startup, a width in a lateral direction of the detection range is reduced based on a predetermined initial angle that is the misalignment amount of the attachment angle of the radar apparatus. After the elapse of the initial period after startup, the width in the lateral direction of the detection range is reduced based on calculation values of the shaft misalignment angle and the shaft misalignment direction.

Abstract: A vehicle control apparatus is provided which includes position detecting means for detecting a position of a detected target using reflection information derived from a radar device 21, first determining means for determining whether the detected target is expected to be an obstacle not based on an intensity of a received reflected wave contained in the reflection information, and second determining means for determining whether an obstacle exists at the position, as detected by the position detecting means, or not using the image information. When the second determining means determines that the obstacle exists, and when a distance between an own vehicle and the detected target is smaller than a given threshold value, the detected target is determined as a target with which collision should be avoided regardless of a result of determination made by the first determining means.

Abstract: A vehicle control apparatus activates a safety device for avoiding a collision of an own vehicle with a target or reducing damage caused by the collision. The vehicle control apparatus sets an activation condition for the safety device. The vehicle control apparatus determines whether each of a plurality of correction conditions for the activation condition is satisfied. The vehicle control apparatus determines whether to activate the safety device on the basis of the activation condition.

Abstract: A driving assistance ECU that serves as a vehicle control apparatus performs traveling control of a vehicle based on a detection result of a radar apparatus that detects a target in the periphery of an own vehicle. An angle calculating unit of the driving assistance ECU calculates an axial misalignment angle that is a misalignment amount of an attachment angle of the radar apparatus by statistically processing angle misalignment information of the radar apparatus acquired at a predetermined cycle. A control processing unit sets the angle misalignment amount of the radar apparatus to a predetermined initial angle until a predetermined initial period elapses after startup, and performs operation restriction on traveling control based on the initial angle. After the initial angle elapses after startup, the operation restriction on traveling control is performed based on a calculation value of the axial misalignment angle.

Abstract: A setting unit of an object existence determination apparatus sets an object-existence determination region with a lateral width in the travelling direction of an own vehicle using a lateral speed of a target object and a determination result by a straight-travel determining unit. An existence determining unit determines, based on the lateral position of the target object and the object-existence determination region, whether there is a possibility of at least part of the target object existing on a travelling course of the own vehicle. The setting unit sets the lateral width of the object existence determination region to be larger as the lateral speed becomes higher, and sets, upon determination that the own vehicle is not travelling straight, the lateral width of the object existence determination region to be smaller than the lateral width of the object-existence determination region used when the own vehicle is travelling straight.

Abstract: An object detection apparatus acquires a lateral position which is a relative position of a target to the own vehicle, and determines that a first target is present, as the target, ahead of the own vehicle and that a second target is present between the first target and the own vehicle. The object detection apparatus determines, based on the lateral position of the first target and a limiting value which indicates a width in the lateral direction, whether the first target is present on a traveling course of the own vehicle. The object detection apparatus sets the limiting value such that when the second target is not present, sets as the limiting value, a predetermined reference value, and when the second target is present, sets as the limiting value, a value different from the reference value.

Abstract: A driving assist ECU which performs collision avoidance control for the target based on a detection result of a target around an own vehicle by a radar device acquires, at a predetermined cycle, angle deviation information of the radar device in the vertical direction, the angle deviation information being calculated from a detection position of the target, and calculates an axis deviation angle by performing statistical processing of a history of the angle deviation information acquired after activation, the axis deviation angle being a deviation amount of a mounting angle of the radar device in the vertical direction. Until a predetermined initial time period elapses after the activation, a limitation is imposed on the collision avoidance control for, among targets detected by the radar device, a stationary target which is a target corresponding to a stationary object.

Abstract: A collision mitigation device sets an actuation condition indicating a condition for actuating a collision mitigating section configured to mitigate collision damage when an own vehicle is in a collision. A target object is positioned near the own vehicle and detected. The collision mitigating section is actuated when a positional relationship between the own vehicle and the target object meets the actuation condition.

The actuation condition is relaxed in such a manner that the collision mitigating section is more easily actuated when the target object is present within the own vehicle traveling segment, compared to when the target object is not present within the own vehicle traveling segment.
