초록 ▼

A vehicle drive force control apparatus including a relationship setting device for setting a standard relationship between a load acting on the engine and a running speed of the vehicle when the vehicle is running in a stable mode at a relatively constant speed on a generally flat road surface, a vehicle-load determining device for determining, from time to time, a running load acting on the vehicle as represented by the load acting on the engine and the running speed of the vehicle, on the basis of the standard relationship set by the relationship setting device, and a drive force control device for controlling the drive force on the basis of the running load acting on the vehicle determined by the vehicle-load determining device.

대표청구항 ▼

An apparatus for controlling an automatic transmission of a motor vehicle having an engine and a drive wheel driven by a drive force based on an output of the engine, said apparatus comprising a transmission controller for shifting said automatic transmission so as to change a speed ratio of said transmission, on the basis of a load acting on the engine and a running speed of the vehicle and according to a predetermined shift boundary line, said transmission controller comprising: relationship setting means for setting a standard relationship between said load acting on said engine and said running speed of the vehicle when the vehicle is running in a stable mode at a relatively constant speed on a generally flat road surface; vehicle-load determining means for determining a running load acting on the vehicle as represented by said load acting on said engine and said running speed, on the basis of said standard relationship set by said relationship setting means; said vehicle-load determining means including means for determining a standard loaded-vehicle speed on the basis of the load acting on the engine and according to said standard relationship, and means for calculating a vehicle load coefficient as said running load, on the basis of said standard loaded-vehicle speed and the detected running speed of the vehicle; and drive force control means for adjusting said predetermined shift boundary line on the basis of said vehicle load coefficient, to chance said speed ratio of said automatic transmission for controlling said drive force of said drive wheel.
