Abstract
A hybrid vehicle includes an engine and a motor that are both capable of powering the wheels. While a vehicle is being driven, the vehicle's driving condition data is monitored. The driving condition data can include steering wheel angle or position, accelerator pedal position, driver torque or power demands, or road grade or incline. The vehicle includes a controller with a specific control scheme to receive the driving condition data, and subject the data to a moving average or a weighted moving average. Based on the averaged driving condition data, the engine is inhibited from stopping under certain conditions to reduce the frequency of the engine turning on and off.
