This vehicle seat control device is provided with a storage unit, a position detection unit, a control unit, and an operation order setting unit. The space on a seat occupied by a passenger sitting in the seat is a sitting passenger-occupied space, and during the execution of an automatic operation, the operation order setting unit is configured to set the operation order such that position adjustments of seat elements operated in the direction of advancing into the sitting passenger-occupied space are started at the same time as, or are started after, the starting of the position adjustments of the seat elements operated in the direction moving away from the sitting passenger-occupied space.

Vehicle seat control device

A vehicle seat adjustment device includes a first adjustment mechanism, a second adjustment mechanism, and a controller. The first adjustment mechanism is moved in a first direction upon driving of a first motor to adjust a position of a vehicle seat. The second adjustment mechanism is moved in both the first direction and a second direction orthogonal to the first direction upon driving of a second motor to adjust the position of the vehicle seat. The controller controls and drives the first motor and the second motor. A speed at which the second adjustment mechanism is moved in the first direction is lower than or equal to a speed at which the first adjustment mechanism is moved in the first direction. When the second motor needs to be driven, the controller drives the second motor while driving the first motor.
