摘要： PROBLEM TO BE SOLVED: To accurately control torque input to an automatic transmission. SOLUTION: A throttle opening (TVO) and an engine speed (Ne) are input to a torque-down amount calculating part 300, which calculates a torque-down amount ΔTe in accordance with the input values. On the other hand, an inertia correction amount calculating part 301 calculates an inertia correction amount (inertia release torque) for each portion and a friction correction amount calculating part 302 calculates a friction correction amount (friction release torque) with a belt CVT. A torque-down amount correcting part 303 corrects the torque-down amount ΔTe in accordance with the calculated correction amount and an engine control part 304 controls engine torque. Thus, the engine torque is controlled in consideration of inertia/friction release torque for each portion and so an upper limit value for the torque input to the automatic transmission is accurately controlled to be a value for allowable torque input to the automatic transmission.

摘要： PROBLEM TO BE SOLVED: To provide a vehicle torque control device that can prevent belt slippage of a belt-type continuously variable transmission. SOLUTION: In a vehicle equipped with a belt-type continuously variable transmission system 1 for a vehicle and an engine 60 that provides torque to the belt-type transmission part, a normal input torque Tp inputted to a primary pulley 21 from the engine 60 and a reverse input torque Ts inputted to the primary pulley 21 from the drive wheel 70 calculated from the normal input torque Tp and the transmission gear ratio of the continuous variable transmission part 20 are calculated. When the total torque which is the sum of the normal input torque Tp and the reverse input torque Ts exceeds the torque capacity in a travelling condition in which the vehicle causes the reverse input, the vehicle torque control device controls the output torque of the engine 60 so that the total torque drops to below the torque capacity of the belt.
