Powertrain management function of a vehicle with CVT transmission

摘要

The invention relates to a method for decreasing the emissions in a drive train comprised of an engine with a controllable torque build-up and a CVT transmission. According to the invention, the regions of higher emissions in an emission characteristic diagram are avoided during accelerations by suitably controlling the torque build-up. This can be achieved in fuel injected engines by limiting the quantity of injection for at least one RPM region. The limiting of quantity can be represented in the form of a characteristic curve and can reproduce the limiting quantity as a function of the RPM.
