Method and apparatus for lane sensing for automatic vehicle steering
MetadataShow full item record
A lane sensing system (20) comprises a processor (22) operable to drive an infrared optical transmitter (24). Light is reflected by a center stripe (18) placed in the center of a highway lane. Reflected light is received in right and left receivers (26) and (28). The processor (22) uses the information to control a power steering control system (30) and a speed control system (32). Information may be encrypted into the center stripe (18) and used by processor (22) to control the speed of the vehicle (10) or to display information to an operator of the vehicle (10) through a display system (34).
