Applied Technology in Road Identification Study of Off-Road Vehicle

Abstract:

To study the problem of the road identification of the off-road vehicle, a road identification method based on on-line monitoring of the vehicle running state was put forward. The time series data of the suspension displacement and the sprung mass were monitored. The spatial power spectrum density was calculated, aiming at automatically identifying the road roughness. The vehicle speed and the longitudinal vibration acceleration were collected, aiming at identifying the terrain slope. The state of the vehicle and engine was recorded. The rolling resistance coefficient was computed, based on the output torque of the engine. Comparing this coefficient with the threshold of the soft road surface, the soft road surface could be identified. On the basis of the identification result of the road feature, the vehicle running mode can be adjusted, improving the maneuverability of the off-road vehicle.
