Methods and systems are provided for operating a continuously variable transmission (CVT) of a driveline of a vehicle during a request for engine compression braking. In one example, a method may include, responsive to an engine compression braking request, operating a CVT via a controller to adjust engine speed according to an engine speed-to-vehicle speed profile selected based on a power-based target engine speed for the engine compression braking request. The power-based target engine speed may vary continuously with driver demanded power and a battery charge power limit of the vehicle.

Methods and system for controlling engine compression braking in a vehicle with a continuously variable transmission

A vehicle includes, an engine, an electric machine having an associated battery, and a controller. The controller is configured to disable the engine and operate the electric machine to propel the vehicle when a proximity of the vehicle to a destination is less than a drive range of the battery.
