Vehicle travel control apparatus
First Claim
1. A vehicle travel control apparatus, comprising:
- a sensor that obtains preceding vehicle speed information representing a vehicle speed of a preceding vehicle, and preceding vehicle information representing at least one of (i) a lateral distance of the preceding vehicle that is measured in a direction that is perpendicular to a traveling direction of a host vehicle from a point falling on an imaginary line that passes through the host vehicle and is parallel to the traveling direction of the host vehicle and (ii) a lateral speed of the preceding vehicle in the direction that is perpendicular to the traveling direction; and
a controller that, during a following mode in which the host vehicle follows the preceding vehicle, determines a target value related to acceleration/deceleration of the host vehicle based on the preceding vehicle speed information such that the host vehicle follows the preceding vehicle, and controls the acceleration/deceleration of the host vehicle such that the target value is implemented, whereinthe controller calculates, based on an operation state of a winker by a driver and the preceding vehicle information, a preceding vehicle leaving probability indicative of a probability that the preceding vehicle is out of a state in which the preceding vehicle is to be followed,during the following mode, the controller suppresses control of the acceleration/deceleration in response to a first predetermined accelerator operation being detected, and cancels suppression of the control of the acceleration/deceleration in response to a second predetermined accelerator operation, having an operation amount less than an operation amount of the first predetermined accelerator operation, being detected,the controller corrects the target value related to the acceleration/deceleration of the host vehicle based on the preceding vehicle leaving probability only in a state immediately after canceling the suppression of the control of the acceleration/deceleration, andsuppressing control of the acceleration/deceleration includes setting an accelerator pedal override state where the controller overrides the target value with a driver demand acceleration calculated based upon the first predetermined accelerator operation.

Abstract
A vehicle travel control apparatus for improved vehicle following includes a sensor that obtains preceding vehicle speed information representing a vehicle speed of a preceding vehicle, and preceding vehicle information representing at least one of a lateral position and a lateral speed of the preceding vehicle with respect to a traveling direction of a host vehicle, and a controller that, during a following mode in which the host vehicle follows the preceding vehicle, determines a target value related to acceleration/deceleration of the host vehicle based on the preceding vehicle speed information such that the host vehicle follows the preceding vehicle, and controls the acceleration/deceleration of the host vehicle such that the target value is implemented. During the following mode, the controller corrects the target value related to the acceleration/deceleration of the host vehicle based on the preceding vehicle information.
