摘要： 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.

摘要： A hybrid electric vehicle includes an intelligent vehicle controller, an electric motor, a battery, an internal combustion engine (ICE), and an electrical generator coupled to the ICE configured to provide electricity to the battery and the electric motor. The intelligent vehicle controller receives ICE power level shifting data from the electrical generator, ICE, battery, and electric motor. The intelligent vehicle controller determines a desirable torque and/or a desirable revolutions per minute (RPM) for the ICE based on the received ICE power level shifting data by utilizing an efficiency map that includes fuel efficiency contours and noise, vibration, and/or harshness (NVH) level lines for the hybrid electric vehicle. The intelligent vehicle controller may have first and second vehicle operation modes, and may derive first and a second desirable power levels for the ICE in the first and second operation modes, based on the ICE power level shifting data.
