Intelligent power management for a vehicle
First Claim
1. A system for intelligent power management in a vehicle, said system comprising:
- a fuel efficiency sensor measuring fuel efficiencies of said vehicle, said fuel efficiency sensor including a dynamometer sensing torques and revolutions per minute (RPMs) of an internal combustion engine (ICE);
a noise, vibration, and/or harshness (NVH) sensor measuring NVH levels of said vehicle;
a measurement unit and map generator producing an efficiency map including a plurality of fuel efficiency contours representing said fuel efficiencies of said vehicle, a plurality of NVH level lines representing said NVH levels of said vehicle, and a plurality of power level curves representing power levels of said ICE;
wherein said efficiency map includes at least one vehicle operation point that corresponds to an acceptable NVH level and/or a desirable fuel efficiency, wherein said at least one vehicle operation point represents a desirable torque and/or a desirable RPM of said ICE.

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.
