Embodiment Construction

[0035] Generally disclosed herein are vehicle power management systems and methods for optimizing power efficiency in a vehicle including multiple power sources by managing power distribution among the power sources. The vehicle is a hybrid vehicle including two or more power sources. Motor power is provided to the vehicle by at least one power source, preferably by a combination of power sources, wherein different sources may power the vehicle in different proportions of the total required power at any one time. The sum of these proportions can reach greater than 100% of the motoring power if there are other power requirements placed on one or more power sources, such as charging the vehicle battery by the internal combustion engine. Many different power splits are possible, and data obtained from the vehicle can be used to determine which power splits result in better vehicle efficiency for a particular vehicle state and power demand.

Abstract

A vehicle power management system (100) for optimising power efficiency in a vehicle (400), by managing a power distribution between a first power source (410) and a second power source (420). A receiver (110) receives a plurality of samples from the vehicle (400), each sample comprising vehicle state data, a power distribution and reward data measured at a respective point in time. A data store (350) stores estimated merit function values for a plurality of power distributions. A control system (200) selects, from the data store (350), a power distribution having the highest merit function value for the vehicle state data at a current time, and transmits the selected power distribution to be implemented at the vehicle (400). A learning system (300) updates the estimated merit function values in the data store (350), based on the plurality of samples.

Description

technical field [0001] The present invention relates to systems and methods of power management in hybrid vehicles. Specifically, but not exclusively, the present invention may relate to a vehicle power management system for optimizing power efficiency by managing power distribution between power sources of a hybrid vehicle. Background technique [0002] The demand for hybrid vehicles is increasing due to growing concerns about the impact of vehicle fuel consumption and emissions. Hybrid vehicles include multiple power sources to provide motoring power to the vehicle. One of these power sources may be an internal combustion engine using petroleum, diesel or other fuel types. Another kind of power source may be a power source other than an internal combustion engine, such as an electric motor. Either power source can provide some or all of the maneuvering power a vehicle needs at a given point in time. Thus, hybrid vehicles offer a solution to concerns about vehicle emiss...
