Abstract
There are provided a torque detection apparatus with high reliability and an electric power steering system and a vehicle which use the torque detection apparatus. The torque detection apparatus () detects the torque based upon a difference in the terminal voltage of the pair of detection coils. In this situation, the torque detection apparatus () outputs two analog torque signals (analog main torque signal Tma and analog sub torque signal Tsa) to the ECU (), and outputs to the ECU () a digital communication signal S in which digital torque values obtained by converting the two analog torque signals to a digital format (main torque value Tm and sub torque value Ts) and diagnosis information Diag of the torque sensor circuit are superimposed.
