Abstract: A travel control apparatus to be mounted on a vehicle includes a computer device configured to perform control to cause the vehicle to travel at a set constant vehicle speed or to cause the vehicle to travel following the preceding vehicle. The computer device includes a determination unit and a target acceleration rate setting unit. The determination unit is configured to, before turn steering is started, determine whether it is a turn opportunity for the vehicle to make a first direction turn. The first direction turn is a turn made by the vehicle deviating from a current travel course without crossing an oncoming travel course. The target acceleration rate setting unit is configured to, in a case where the determination unit determines that it is the turn opportunity, perform control to reduce acceleration before the turn steering is started.

Abstract: A traveling control apparatus for a vehicle includes a steering angle detector, a vehicle speed detector, and a cruise control unit. The cruise control unit includes a steering angle speed detector, a steering angle correction value setting unit, and a target acceleration rate setting unit. The steering angle correction value setting unit sets a steering angle correction value, on the basis of a speed of the vehicle detected by the vehicle speed detector and a steering angle speed calculated by the steering angle speed detector. The target acceleration rate setting unit sets a target acceleration rate of a cruise control, on the basis of a steering angle and the speed of the vehicle. The steering angle is based on an addition of the steering angle correction value set by the steering angle correction value setting unit to the steering angle absolute value detected by the steering angle detector.
