CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE AND CONTINUOUSLY VARIABLE SPEED CHANGE GEAR

摘要

A control device for an internal combustion engine and a continuously variable speed change gear according to the present invention includes a continuously variable speed change gear in a driving force transmitting system between the internal combustion engine and driven wheels and can control an output of the internal combustion engine. Particularly, a target driving torque (Tet) is set on the basis of: a driving torque (Td) given to a vehicle; a vehicle body driving torque correction value (Tiv) acting as a first running resistance of the vehicle based on a vehicle body acceleration; a gear change torque fluctuation correcting value (Tcv) acting as a second running resistance by being consumed by gear change operations of the continuously variable speed change gear; and a vehicle speed correction torque (Tv) required for eliminating a deviation ( DELTA v) based on the deviation ( DELTA v) between a target vehicle speed (Vt) and an actual vehicle speed (V); whereby the output of the internal combustion engine is controlled by the target driving torque (Tet), so that the target driving torque (Tet) can be set by a selected use of an optimum torque correction value in accordance with the operating conditions, the internal combustion engine can be controlled at an output corresponding to the target driving torque, and slips of steel belts due to an excessive output and shocks at the time of gear change can be avoided.
