Onboard control device

To quickly determine whether or not the propulsive force of a vehicle drive source is abnormal. The onboard control device pertaining to the present invention has a drive manipulated variable detection unit (101) for detecting or estimating a drive manipulated variable manipulated by a driver in order to impart propulsive force to a vehicle, a command value calculation unit (109) for calculating a command value for a drive source of the vehicle on the basis of the drive manipulated variable, a propulsive force control unit (115) for controlling the propulsive force of the drive source on the basis of the command value, operating state detection units (102, 103) for detecting or estimating the operating states of the drive source, a drive manipulation rate of change calculation unit (110) for calculating the rate of change in drive manipulation, an operating state rate of change calculation unit (111) for calculating the rate of change in the operating state, and an abnormality detection unit (112) for detecti
