A motion manager that is mounted on a vehicle includes a processor and a memory. The processor receives a motion request that corresponds to an application from individual applications. The processor arbitrates the received motion request. The processor generates, based on an arbitration result, an instruction value of an operation request to be output to a brake control unit. The memory stores, in advance, type information of an actuator to be controlled by the brake control unit. The processor generates the instruction value of the operation request using the type information.
