Excerpt from Computer Design April 1992 FUZZY LOGIC WILL MAKE CARS SMARTER ---------------------------------- It's estimated that by the end of the century, the amount of electronics in automobiles will double. Among the areas of interest are an emission control system that would continuously monitor the exhaust gases and make adjustments to the carburetor and ignition systems to keep the levels of hydrocarbons and other toxic elements within specified limits. Interior climate control would be able to adjust to the number of passengers like some fuzzy controlled air conditioning systems do today. Fuzzy controlled digital signal processors are being investigated for interior noise cancellation systems. Today's digital anitlock braking systems work by cycling the brakes rapidly on and off. A fuzzy controller could presumably provide smooth antilock braking by adjusting hydraulic pressure in accordance with slight amounts of wheel rotation. One item under active development is a multiple mode automatic transmission. By sensing rotation, torque, engine speed and throttle position, a fuzzy controller could determine the proper shift points. By selecting a different set of rules and membership functions the driver could set the transmission for smooth shifting, optimal economy shifting or sport shifting. ------------------------------------------------------------ This is article is provided with permission from Computer Design.
