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:
“You may drive a dog off the King’s armchair, and it will climb into the preacher’s pulpit; he views the world unmoved, unembarrassed, unabashed.”
—Jean De La Bruyère (1645–1696)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
“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)
