PROBLEM TO BE SOLVED: To actively perform a failure diagnosis to perform the diagnosis of all components by providing, within a self-diagnostic means, a self-diagnostic vehicle property changing means for determining the manipulated variable of the actuator of a drive source so as to be actively detectable of failure and transmitting it to a controlled variable output means. SOLUTION: This device comprises a vehicle property input means 101 for inputting the signal from each part sensor, a driving force control means 102 for controlling and requesting the driving force distribution to a plurality of drive sources, a controlled variable arithmetic means 103 for calculating the actuator manipulated variable and a controlled variable output means 104, and a self-diagnostic means 105 for detecting the failure of a system. The self- diagnostic means 105 is provided with a self-diagnostic condition judgment means 106 and failure judgment means 108 for judging whether it is detectable of failure at present or not, and a failure memory means 109. Further, it is also provided with a self-diagnostic vehicle property changing means 107 for determining the manipulated variable of the actuator of the drive source so as to be actively detectable of failure and transmitting it to the controlled variable output means 104. |
