<P>PROBLEM TO BE SOLVED: To provide a vehicle travel control device, capable of reducing a load of a steering operation of a driver, during vehicle lane following control, when the driver performs intervention of the steering operation in order to go closer to a vehicle lane center. <P>SOLUTION: A vehicle lane following control means (target lateral position setting part) sets a target lateral position Y* to a vehicle lane center 1m when it is determined that there is a return intention of a driver to the vehicle lane center 1m. A vehicle lane center return intention determination means (vehicle lane center return intention determination part) determines that there is the return intention of the driver to the vehicle lane center 1m when a steering direction of the driver is a direction from an outer side of the vehicle lane toward the center 1m and a detected steering state quantity (steering torque T) exceeds a second threshold (threshold T2) larger than a first threshold or when a predetermined forward arrival point (predicted arrival point) SP in a predicted trajectory S of the own vehicle MC estimated on the basis of a detected vehicle motion state quantity (yaw rate ψ', vehicle speed V) is beyond the vehicle lane center 1m. <P>COPYRIGHT: (C)2013,JPO&INPIT |
