METHOD AND MODULE FOR ESTIMATING AFTER-CHARGE DRIVABLE RANGE OF ELECTRIC VEHICLE AND DRIVING ASSISTANCE DEVICE
First Claim
1. A method for estimating an after-charge drivable range of an electric vehicle, comprising:
- a power supplement location selecting step which uses a charging device status updating interface to acquire information associated with at least one power supplement location;
a planned charging time determining step which calculates uses a micro-controller unit(MCU) to calculate an estimated driving time for arriving at each of the at least one power supplement location and to calculate an estimated charge waiting time at each of the at least one power supplement location according to current driving information at a current time and the information associated with each of the at least one power supplement location, and to determine a planned charging time of the electric vehicle at each of the at least one power supplement location according to a specified time, the specified time being a specified charging time duration or a specified charging finish-time, wherein when the specified time is the specified charging time duration, the planned charging time is equal to the specified charging time duration, and when the specified time is the specified charging finish-time, the planned charging time is a result of a subtraction of the current time, the estimated driving time, and the estimated charging waiting time from the specified charging finish-time;
an after-charge total power estimating step which uses the MCU to calculate a total power of the electric vehicle when arriving at each power supplement location and starting to be charged as an estimated pre-charge total power, to calculate calculates an estimated power increment of the electric vehicle at each of the at least one power supplement location according to the planned charging time, and to sum the estimated pre-charge total power and the estimated power increment as an estimated after-charge total power of the electric vehicle at each of at least one power supplement location; and
an after-charge drivable range estimating step which uses the MCU to calculate an estimated after-charge drivable range of the electric vehicle centering at each of the at least one power supplement location according to the current driving information and the estimated after-charge total power.

Abstract
A method and module for estimating after-charge drivable range of an electric vehicle and a driving assistant device are provided. The method includes a power supplement location selecting step, a planned charging time determining step, an after-charge total power estimating step, and an after-charge drivable range estimating step. The planned charging time determining step calculates an estimated driving time for arriving at each power supplement location and an estimated charge waiting time, and determines a planned charging time at each power supplement location. The after-charge total power estimating step calculates an estimated power increment of the electric vehicle and an estimated after-charge total power. The after-charge drivable range estimating step calculates an estimated after-charge drivable range of the electric vehicle centering at each power supplement location according to the current driving information and each estimated after-charge total power.
