Abstract
A hybrid vehicle includes an engine, an electric machine, a traction battery electrically connected to the electric machine, and a controller. The controller is programmed to, in response to the vehicle approaching a decline, overrepresent a state of charge (SOC) of the traction battery to cause a torque command to the engine to decrease and a torque command to the electric machine to increase such that discharge of the traction battery increases in advance of the decline.
