An intelligent micro-vehicle(IMV) system with high real-time performance, stability and low performance sensors is designed in this paper. And a complete interaction control method Based on vision, which includes car-following and lane-change, is proposed over it. To improve vehicle interactive performance, the Fuzzy hybrid steering controller is proposed for autonomous overtaking here. Experimental...
More than ten unconnected upward positive leaders initiated from high structures in response to natural downward-moving negative leaders are analyzed. These leaders are observed by using high-speed cameras with sampling rates at the order of 104 fps (frames per second). The propagation velocity, channel width of the unconnected upward leader and the distances between it and strike point are presented...
Using the simultaneous high-speed camera records and channel-base current records in an artificially triggered negative lightning, the correlation between channel-base current and integrated luminosity (IL) of air-ionized part of lightning channel is analysed. Depending on the current's changing trend (ascending or descending), and the luminosity property of those pixels used in calculating IL from...
A new method for the calculation of the linear charge density (LCD) and current in upward positive leader (UPL) is put forward in this study. It is tested in three classical artificially triggered lightning discharges. The current calculated based on the charge density and the velocity of the leader are compared with the measured current, relative brightness of the leader channel in the frame of high-speed...
