PURPOSE:To improve precision of estimated output shaft torque by effecting correction by considering lowering of precision owing to the change with a time of an output shaft torque estimating device. CONSTITUTION:In a vehicle 32 having a driven means by an internal combustion engine 1 or a motor, a torque correction device comprises a first torque estimating means 6 to detect torque of a drive shaft; a second torque estimating means 5 used for correction of torque determined by the first torque estimating means 6: and a learning correction means 4 to compare estimating torque calculated by the first and second estimating means 6 and 5 with each other and learning and deciding the starting of correction. |
