| 抄録（英） | Acquisition and utilization of lateral guidance information is crucial for steering a vehicle. Drivers can successfully perform the steering function using visual perception and hand-eye coordination, but with loss of visual information (e.g. during whiteout conditions), this seemingly simple task becomes difficult. In order to improve the safety and efficiency of snow removal operations, a supplemental steering guidance display, based on information obtained from the magnetic markers embedded in the roadway, was proposed and successfully implemented in a California Department of Transportation (Caltrans) snowplow. The steering guidance display problem was transformed into a robust driver-in-the-loop control problem by considering the "display" law as part of the overall driver-steering-control algorithm. This paper verified the two key "assumptions" of this design using the initial snowplow test data: (1) the "display" law is designed in such a way that drivers can use "proportional" control gain alone to satisfy the performance and stability requirements of the steering tasks, and (2) the driver steering model can be described as a combination of gain and dynamic delay under the display law in (1). 翻訳 |
