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:
“Men of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.”
—Francis Bacon (1561–1626)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
“While you are nurturing your newborn, you need someone to nurture you, whether it is with healthful drinks while you’re nursing, or with words of recognition and encouragement as you talk about your feelings. In this state of continual giving to your infant—whether it is nourishment or care or love—you are easily drained, and you need to be replenished from sources outside yourself so that you will have reserves to draw from.”
—Sally Placksin (20th century)
