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:
“Did I make you go insane?
Did I turn up your earphone and let a siren drive through?
Did I open the door for the mustached psychiatrist
who dragged you out like a golf cart?
Did I make you go insane?”
—Anne Sexton (1928–1974)
“Only mediocrities progress. An artist revolves in a cycle of masterpieces, the first of which is no less perfect than the last.”
—Oscar Wilde (1854–1900)
“Democracy and equality try to deny ... the mystic recognition of difference and innate priority, the joy of obedience and the sacred responsibility of authority.”
