The present invention can stabilize driving of a motor even if multiple control instructions of driving the motor are acquired through non-real-time communication. A servo driver (10) does not perform processing corresponding to other control commands when acquiring the other control commands from other interfaces through non-real-time communication in a process of performing processing corresponding to a control command acquired via one interface and through non-real-time communication.

A vehicle includes a powerplant and a body. The body defines a passenger cabin and a box and having a tailgate mounted to the box. A step assembly is associated with the box and includes a step and a handle. The handle has a sensor configured to receive input from a user located outside of the passenger cabin and output a signal when the input is active. A controller is programmed to, in response to the signal being received, command a torque to the powerplant to propel the vehicle based on the signal.
