Abstract
A low-cost torque detection apparatus is obtained using wheel revolution sensors which are generally provided in a conventional ABS and an engine revolution sensor which is generally provided in a conventional engine fuel jet controller. The apparatus can be used, for example, in a vehicle having a drive source, such as an engine or a motor, for driving wheels which is coupled to the right and left wheels by respective shafts having torsional stiffness for transmitting a drive torque through a differential gear. The apparatus includes a drive source revolution angle detection device for the drive source and wheel revolution angle detection means for the right and left wheels, and calculates torques of shafts such as drive shafts for coupling the differential gear to the wheels using a torque calculator.
