Abstract:
1. A driving force control device of a vehicle including a power source and an automatic transmission connected to said power source; said control device setting target driving force generated on a drive wheel side relative to said automatic transmission, calculating output torque to be generated in said power source, based on said target driving force and a gear ratio of said automatic transmission, controlling said gear ratio of said automatic transmission based on said target driving force, calculating a gear ratio based on input and output revolution speeds of said automatic transmission, determining abnormality of said automatic transmission, based on said calculated gear ratio and a gear ratio instruction value for controlling said automatic transmission based on said target driving force, in calculating said output torque, calculating the output torque to be generated in said power source by using any of said calculated gear ratio and said gear ratio instruction value, based on a result of determination, and in calculating said output torque, when determination as abnormal is made, the output torque to be generated in said power source is calculated by using a larger gear ratio out of said calculated gear ratio and said gear ratio instruction value.
