摘要：	A terrain previewing system has been created for the experimental active suspension vehicle that exists at Defence Research Establishment Suffield. The system employs ultrasonic transducers to measure the terrain elevation just ahead of the vehicle's front wheels. The elevation information is processed and correlated to vehicle forward speed by an on-board microcomputer. The elevation profile is then passed to the active suspension control computer so that algorithms used to control the active suspension actuators can have advance warning of bumps and dips. Preliminary results on a fabricated steel bump show that active control using preview information performs significantly better than passive suspension and measurably better than active control without preview.
