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:
“No one should drive a hard bargain with an artist.”
—Ludwig Van Beethoven (1770–1827)
“The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower.”
—Robert M. Pirsig (b. 1928)
“Design in art, is a recognition of the relation between various things, various elements in the creative flux. You can’t invent a design. You recognise it, in the fourth dimension. That is, with your blood and your bones, as well as with your eyes.”
—D.H. (David Herbert)
