Abstract
A travel control device for a vehicle has a steered angle varying device 14 or a by-wire type steering device 96 which modifies a relationship of steered angle of steerable wheels to steering operation amount by a driver. When the control device decides that vehicle trajectory control is to be initiated or renewed, it calculates a target steered angle of the steerable wheels for driving the vehicle along a target trajectory which is required for the vehicle to arrive at a target arrival position in a target traveling direction on the basis of steering operation amount by a driver and vehicle speed at a time point of the decision. The control device controls the steered angle of the steerable wheels according to the target steered angle in feed-forward or feed-back manner.
