A braking control apparatus for controlling a braking operation for an own vehicle is configured to: acquire information on an object detected around the own vehicle; calculate, when a collision between the own vehicle and the object is predicted based on both an estimated route of the object estimated based on the acquired information on the object and an estimated route of the own vehicle, a collision range in the own vehicle at a collision timing between the own vehicle and the object or a collision range in the object at the collision timing; and control, according to a positional relationship between a predetermined braking-unrequired range in the own vehicle and the calculated collision range in the own vehicle or a positional relationship between a predetermined braking-unrequired range in the object and the calculated collision range in the object, whether to perform the braking operation for the own vehicle.

Braking control apparatus

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.

Vehicle control apparatus and vehicle control method

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.

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.
