Abstract: A backward movement control device performs a backward movement control of an articulated vehicle including a tractor that includes steered wheels and a trailer towed by the tractor. The tractor is equipped with a steering control device that executes feedback control for causing a steered angle of the steered wheels of the tractor to follow a target steered angle. The backward movement control device includes a control unit configured to calculate the target steered angle such that a virtual steered angle follows a target virtual steered angle when a backward movement operation of the articulated vehicle is performed. The virtual steered angle is a steered angle of steered wheels that are virtually present in the trailer if the trailer is regarded as a rigid vehicle. The target virtual steered angle is a target value of the virtual steered angle that is set through a specific operation by an operator.
