Abstract

A vehicle travel control system includes a first unit configured to calculate a target longitudinal acceleration/deceleration control command of the own vehicle based on a distance or a relative speed between the own vehicle and a forward obstacle, traveling route information from a vehicle navigation system or a Global Positioning System, and input information such as a vehicle speed set by a driver; a second unit configured to calculate a target longitudinal acceleration/deceleration control command according to a lateral jerk that acts on the own vehicle; and an arbitration unit configured to perform, based on the target longitudinal acceleration/deceleration control command calculated by the second unit, arbitration of the target longitudinal acceleration/deceleration control command calculated by the first unit, wherein output from the arbitration unit is set as a command to control the target longitudinal acceleration/deceleration control command of the own vehicle.
