PURPOSE:To make study control of a line pressure at shifting using parameters which are the most related to a shift shock. CONSTITUTION:An inertia torque Tins is sensed (A) on the basis of the change rate dNe/dtins of the engine rotation in the inertia phase during shifting. On the basis of the degree of throttle opening TVOins in the inertia phase, the reference inertia torque To is set (B). The obtained inertia torque Tins is compared with this reference value To, and the optimum line pressure at shifting is studied (C), and the study correction value PLHO for the line pressure at shifting is set (D1). |
