Abstract
Official abstract text for this publication.
Disclosed is a control apparatus of a vehicle which can control an internal combustion engine and a continuously variable transmission. The control apparatus is partly constituted by an ECU adapted to calculate a required drive force and a fuel consumption amount G. The ECU then calculates a time required for the speed change operation with reference to a speed change time map when a variation amount of the accelerator opening degree and a change speed of the accelerator opening degree are calculated. The ECU then calculates the speed change speed, and calculates a transmission efficiency η of a CVT. The ECU then calculate the ratio G/η of the transmission efficiency η and the fuel consumption amount G, thereby setting the engine rotational speed at which the above ratio is at the smallest level as a target engine rotational speed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control apparatus of a vehicle, comprising: an internal combustion engine, and a continuously variable transmission operative to change a speed of a rotation of an output shaft of the internal combustion engine to be outputted to drive wheels, the continuously variable transmission including a primary pulley, a secondary pulley and a transmission belt wound around in a V-groove between the primary pulley and the secondary pulley, wherein an outpu…
