Abstract: A driving assistance system includes an electronic control unit and a notifying unit. The electronic control unit detects an inter-vehicle distance and relative velocity, controls the subject vehicle, performs a first notification operation when the inter-vehicle distance becomes equal to or larger than a first distance and the relative velocity becomes equal to or higher than a first velocity, or equal to or larger than a second distance, sets an inter-vehicle distance when the forward vehicle and the subject vehicle are stopped as a reference inter-vehicle distance and performs a second notification operation when a difference between the reference inter-vehicle distance and the inter-vehicle distance becomes equal to or larger than a third distance. The electronic control unit does not perform the second notification operation at least until after the first notification operation is performed.

Abstract: 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.

Abstract: A vehicle control apparatus for implementing inter-vehicle distance control of a vehicle carrying the apparatus behind a preceding vehicle. In the apparatus, an offset storage is configured to calculate an offset that is a difference between detected distances to first and second targets, and store the offset associated with the first target forward of the second target. The inter-vehicle distance control may be implemented based on a distance calculated by subtracting the offset from the detected distance to the first target. An offset updater is configured to determine whether or not a relative distance between the first and second targets has increased or decreased, and when the relative distance between the first and second targets has increased or decreased, update the offset stored by the offset storage.

Abstract: A cruise control device of a vehicle including an engine and a multistep automatic transmission, includes an acceleration operation part, a driving-force operation part, and a control part that carries out acceleration control in which a driving force is brought close to a target driving force by changing a throttle-valve opening of the engine at least to bring the driving force close to a demand driving force. The control part carries out the acceleration control in a target gear shift stage fixed mode that is a control mode in which the acceleration control is carried out in a state where change of a gear shift stage is forbidden after changing the gear shift stage from a current gear shift stage that is a gear shift stage at present to a target gear shift stage that is a gear shift stage required for obtaining the target driving force at a stretch.

Abstract: 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 of the preceding vehicle. A target-pair distance is a distance between the target and a non-target reflection point that is closer to the subject vehicle than the target. A corrected distance calculator is configured to, in the presence of the target-pair distance being recognized, calculate a first corrected distance by subtracting the target-pair distance from a detected distance between the target and the subject vehicle, and in the absence of the target-pair distance being recognized, calculate a second corrected distance by subtracting an offset that is the previously set target-pair distance from the detected distance. A controller is configured to implement the inter-vehicle distance control based on the first or second corrected distance depending on the presence or absence of the target-pair distance being recognized.

Abstract: 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 distance estimator is configured to calculate an estimated distance as an inter-vehicle distance between a rear end of the preceding vehicle and the subject vehicle based on an inter-vehicle distance variation calculated based on a relative speed of the target. A target determiner is configured to determine whether or not the target is displaced forward of the rear end of the preceding vehicle. A controller is configured to, when the target of the preceding vehicle is displaced forward of the rear end of the preceding vehicle, implement the inter-vehicle distance control based on the estimated distance calculated by the distance estimator.
