摘要： An electronic event recorder for attachment to a vehicle is provided which can broadcast encrypted signature and data, thereby leaving behind an electronic version of a “fingerprint” in the event of an accident or traffic violation. The fingerprint, captured by an external data acquisition system or another vehicle so equipped, provides a history of events related to the vehicle. The event recorder is preferably integrated on a smart card and housed in a tamper proof casing. In a first mode of operation, monitoring stations along the roadways periodically send an interrogation signal, such as when radar detects that the vehicle is speeding. Upon receiving the interrogation signal the smart card transmits the vehicle's signature information to the monitoring station where it is time and date stamped along with the speed of the vehicle. In a second mode of operation, when a sensor detects a sudden or violent acceleration or deceleration, such as occurs during a collision, a smart card mounted in each car will exchange signature information automatically. This is particularly useful when the collision occurs in a parking lot when one of the hit vehicles is typically unattended.

摘要： A detector for detecting light, such as infrared light, reflected from discontinuous lane dividing lines or other lines on a highway surface from a moving motor vehicle to determine the position of the vehicle on the highway detects light reflected from the surface of the highway and includes circuitry to determine from the reflected light sensed not only the presence of a road line but a characteristic of the road line sensed to determine if the road line detected is consistent with previously detected road lines and therefore appears to be a valid road line. The alarm, when enabled, is activated unless a road line consistent with previously sensed road lines is sensed within successive fixed periods of time in which it is expected that a line should be sensed. By detecting the beginning and end of a signal, various characteristics of the sensed line can be determined, and such things as the type of line likely sensed or the speed of travel of the vehicle can also be determined.
