DRIVING FORCE CONTROL DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To improve operational performance at accelerating/decelerating time by absorbing inertia torque by correcting output on the basis of inertia torque calculated on the basis of an engine speed and the speed change ratio. SOLUTION: An inertia correction quantity DTHCMD is arithmetically operated (S22) by detecting actual NDR (equivalent to a detecting engine speed) from output of a rotating speed sensor (S20). The inertia correction quantity DTHCMD is arithmetically operated on the basis of the speed change ratio (the ratio of a driven shaft rotating speed NDN to a driving shaft rotating speed NDR), target NDR (NDRCMD) and detecting NDR. Next, whether or not a vehicle is an accelerating state is judged (S24), and when in the accelerating state, the inertia correction quantity DTHCMD is added to previously found target throttle opening THCMD1 (S26). When not in the accelerating state, whether the vehicle is in a decelerating state is judged (S28), and when in the declerating state, the inertia correction quantity DTHCMD is subtracted from the targed throttle opening THCMD1 (S30).
