Drive Cycle Recognition (abbr. DCR) is an advanced vehicle control strategy that uses past driving information, as well as a library of representative drive cycles to extrapolate future vehicle control parameters. For example, the vehicle computer can identify past driving history as one particular representative cycle (say, FTP-75) and use known information from FTP-75 to improve vehicle performance. This type of control strategy is most useful for hybrid vehicles where the control strategy has a much greater effect on vehicle performance than with a regular internal combustion engine driven vehicle.
Identification techniques can be as simple as numerical error calculations (such as Mean squared error) or as complex as a self-organizing competitive neural network.
Famous quotes containing the words drive, cycle and/or recognition:
“The mission of men there seems to be, like so many busy demons, to drive the forest all out of the country, from every solitary beaver swamp and mountain-side, as soon as possible.”
—Henry David Thoreau (1817–1862)
“Oh, life is a glorious cycle of song,
A medley of extemporanea;
And love is a thing that can never go wrong;
And I am Marie of Roumania.”
—Dorothy Parker (1893–1967)
“The recognition of Russia on November 16, 1933, started forces which were to have considerable influence in the attempt to collectivize the United States.”
