Abstract:
A control system for a vehicle having a variable displacement engine, a motor, an electrical storage device operatively connected to the motor, a driver operated control, and a sensor for detecting a vehicle operating condition, the control system comprising:a controller in communication with the engine, the motor, the driver operated control, and the sensor, the controller being configured to at least, a) receive an input from at least one of the driver operated control and the sensor, b) determine a demanded torque based on the input received, c) compare the demanded torque to a first torque threshold, d) partition the demanded torque into an engine torque and a motor torque based on the comparison of the demanded torque to the first torque threshold, e) compare the demanded torque to a second torque threshold when the engine torque is non-zero, and f) determine a number of operating cylinders for the engine based on the comparison of the demanded torque to the second torque threshold.
