To provide a vehicular control device capable of determining a failure content causing a transmission failure of drive force from a drive force source.
The vehicular control device comprises a control means 22 for performing a motion control of a main pump MP and an auxiliary pump EP, a speed change mechanism 15 for changing and transmitting the rotational speed of an input member 15a to an output member 15b using hydraulic pressure of a working fluid supplied from the main pump MP and the auxiliary pump EP, a transmission failure judgment means 23 for determining the transmission failure of the speed change mechanism 15 based on the rotational speed of the input member 15a and the rotational speed of the output member 15b, and a failure judgment means 24 for making a judgment of the failure content causing the transmission failure based on the result of the re-judgment by re-judging by the transmission failure judgment means 23 after the rotational speed of the main pump MP is made not less than the judged threshold by the control means 22 in the case where it is judged as transmission failure by the transmission failure judgment means 23 while the rotational speed of the main pump MP is less than the predetermined judged threshold.
