PROBLEM TO BE SOLVED: To suppress torsional vibration generated in a power transmission system by accurately estimating behavior of the power transmission system even in shift change for changing a speed reduction ratio of a transmission.SOLUTION: A control device for a vehicle includes a behavior estimating portion 27 for estimating various state quantities including a wheel-side estimated speed ω' and engine-side estimated speed ω' of a drive shaft 3 by using an observer equation, and a feedback portion 22 calculating a torque correction quantity Tas a correction quantity of a request torque Tof an engine 1 according to driver's operation on the basis of an estimated speed difference (ωb'-ωe') as the difference between both speeds, and outputting the calculated torque correction quantity Tto a torque control portion 23. The torque control portion 23 controls each section of the engine 1 so that a corrected target torque Tas a value obtained by adding the torque correction quantity Tinput from the feedback portion 22, to the request torque T, is generated in the engine 1. |
