Abstract
A control system that controls speed of an internal combustion engine (ICE) in a series hybrid vehicle includes an accelerator pedal, a vehicle speed sensor and a controller. The accelerator pedal sends a torque request signal. The vehicle speed sensor sends a vehicle speed signal. The controller receives the torque request signal and the vehicle speed signal. The controller is configured to calculate, based on the torque request and vehicle speed signals, a driver power request; calculate engine power limits including (i) a maximum engine power that includes the driver power request plus an upper offset; and (ii) a minimum engine power that includes the driver power request minus a lower offset; select a most efficient engine operating point between the maximum and minimum power; and control the ICE to operate at the most efficient engine operating point.
