Abstract

The range of a vehicle is managed by identifying at least one energy deficit/surplus point to a destination. A speed and torque profile for a destination is determined by a range extender control unit (RECU) using one or more vehicle parameters (e.g. distance to destination, elevation, time, idle point(s), vehicle weight, drag co-efficient, frontal area, tyre rolling radius, tyre rolling resistance co-efficient, gear ratio, motor torque, speed and efficiency map). The speed and torque profile is used to determine: (i) an energy requirement profile from a vehicle battery; and (ii) with at least one other parameter (e.g. battery capacity), a battery energy availability profile to the destination. The difference between the energy requirement profile and the battery energy availability profile is used to identify the energy deficit/surplus point(s). The energy deficit/surplus point(s) is finalised if the vehicle can reach the destination using the identified deficit/surplus point(s). The vehicle range-extender and battery power delivery systems are controlled by estimating the most appropriate point(s) in time to operate the range-extender system, even if the battery state-of-charge (SOC) is not necessarily low. The holistic usage pattern of a customer, including the charging pattern and the charging eco-system, is considered.
