Drive-pattern evaluation device and drive-pattern evaluation method

A drive-pattern evaluation device which evaluates a past actual drive pattern of a moving body based on energy consumption, the device comprising:

• a processor coupled with a memory in which instructions are stored which are executed by the processor configured to:
• generate an energy-saving drive pattern in consideration of energy consumption with respect to an evaluation section of said past actual drive pattern by:
• extracting an actual speed at which the moving body was moving on said evaluation section of said actual drive pattern, and applying said extracted speed as a condition to be met by said energy-saving drive pattern, and
• calculating said energy-saving drive pattern as a function of speed versus time which reduces a total acceleration amount relative to said actual drive pattern;
• estimate energy consumption in said evaluation section by said energy-saving drive pattern as an estimated energy-saving consumption by:
• extracting speed information from said energy-saving drive pattern,
• extracting information of an elevation difference of a road link in said evaluation section from map information, and
• feeding respective parameters of said speed information from said energy-saving drive pattern and said information of said elevation difference from said map information into an equation that calculates energy consumed by said moving body during said evaluation function as a function of said parameters;
• estimate, by use of speed information of said actual drive pattern and map information, energy consumption in said evaluation section by said actual drive pattern as an estimated actual energy consumption by:
• extracting speed information from said actual drive pattern, and
• feeding respective parameters of said speed information of said actual drive pattern and said information of said elevation difference from said map information into said equation;
• and
• compare said estimated energy-saving consumption and said estimated actual energy consumption, to evaluate said actual drive pattern based on the comparison result;
• and
• a display or speaker configured to output information on the evaluation of said actual drive pattern.
