Patent attributes
A vehicle traveling control device includes: a deceleration correction determination unit, a lane detection evaluation unit, a control gain setting unit, and a deceleration control unit. The deceleration correction determination unit acquires information on a curve ahead of a host vehicle and determines on a basis of the curve information whether host vehicle speed deceleration correction is necessary during entry to the curve. The lane detection evaluation unit evaluates a road surface situation of a road prior to the curve entry by a state of detection of a lane ahead of the curve in a case where the deceleration correction is determined necessary. The control gain setting unit sets a control gain of the deceleration correction on a basis of an evaluation value of the lane detection state. The deceleration control unit performs host vehicle speed deceleration control during the curve entry on the basis of the control gain.
