Abstract
A system for intelligent power management for a vehicle includes a fuel efficiency sensor, a dynamometer, an noise, vibration, and/or harshness (NVH) sensor, and a measurement unit & map generator. The fuel efficiency sensor measures fuel efficiencies of the vehicle. The dynamometer senses torques and revolutions per minute (RPMs) of an internal combustion engine (ICE). The NVH sensor measures NVH level, for example noise and/or vibration levels, of the vehicle. The measurement unit & map generator produces an efficiency map including a plurality of fuel efficiency contours, a plurality of NVH level lines, and a plurality of power level curves. The efficiency map includes at least one vehicle operation point that corresponds to an acceptable NVH level and/or a desirable fuel efficiency, and that represents a desirable torque and a desirable RPM of the ICE.
