A vehicle control apparatus for implementing inter-vehicle distance control of a subject vehicle carrying the apparatus behind a preceding vehicle based on reflected waves from a target that is a reflecting portion of the preceding vehicle. In the apparatus, a controller is configured to implement the inter-vehicle distance control based on an inter-vehicle distance between a rear end of the preceding vehicle and the subject vehicle acquired from the detected distance. A control switcher is configured to, when target information for identifying the rear end of the preceding vehicle becomes unacquirable during implementation of the inter-vehicle distance control, suspend the inter-vehicle distance control and make a switch to the direct operation by the driver.

A method controls an at least partially autonomous ego motor vehicle having a positive driving behavior in the event of turning off or a lane change of a relevant road user. The method includes determining a current shortest distance between the ego motor vehicle and the relevant road user, determining a safety measure which contains a collision probability, determining an ideal speed of the ego motor vehicle at which a predefined safety measure is attainable, and determining a speed-based adjustment value for acceleration and/or deceleration of the ego motor vehicle based on the ideal speed. The method further includes determining a distance-based adjustment value for acceleration and/or deceleration of the ego motor vehicle based on a hazard factor kept available by the storage unit, selecting between the speed-based adjustment value and the distance-based adjustment value, and controlling deceleration or acceleration of the ego motor vehicle.

Provided is a vehicle travel control apparatus, mounted on a host vehicle, which performs travel control of the host vehicle on the basis of a positional relationship between the host vehicle and a preceding vehicle traveling ahead of the host vehicle, the vehicle travel control apparatus including a millimeter wave sensor that acquires target data of the preceding vehicle by receiving a reflected wave of an emitted electromagnetic wave; and an ECU that determines the presence or absence of a preceding vehicle traveling directly ahead of the host vehicle on the basis of the target data acquired by the millimeter wave sensor and that performs acceleration and deceleration control of the host vehicle on the basis of the presence or absence of the preceding vehicle. The ECU performs the acceleration and deceleration control of the host vehicle so that the acceleration or deceleration is suppressed in a case of the occurrence of target misidentification in which the millimeter wave sensor acquires a plurality of pieces of target data with respect to the same object.

A driver assistance system and an operating method thereof are configured and adapted to perform autonomous longitudinal and/or lateral control of a vehicle. At least one control task for longitudinal and/or lateral control of the vehicle can be transferred from the driver to the driver assistance system. This involves informing the driver that a control task can be transferred to the system, and then transferring the control task from the driver to the system in response to the driver ceasing a manual control of this control task.

A controller that controls operation of the motorcycle, to which a surrounding environment detector is mounted, includes: an acquisition section that acquires information on the surrounding environment of the motorcycle on the basis of output of the surrounding environment detector during travel of the motorcycle; and an adaptive cruise operation performing section that makes the motorcycle perform adaptive cruise operation on the basis of the surrounding environment information acquired by the acquisition section. The acquisition section acquires other vehicle travel state information that is information on a travel state of an other vehicle acquired by a different vehicle from the motorcycle via wireless communication. The controller further includes a safety operation performing section that makes the motorcycle currently performing the adaptive cruise operation perform safety operation on the basis of the other vehicle travel state information acquired by the acquisition section.
