This paper presents a novel approach for pedestrian detection in nighttime with a normal camera. Generally, there is a real-time requirement in the pedestrian detection system which limits the computational complexity of algorithms. Thus most systems utilize the thresholding method for pedestrian detection or segmentation. However, the single adaptive threshold based approach doesn't always work well and sometimes gives poor results. In this paper, we propose adaptive hysteresis based segmentation algorithm which holds two adaptive thresholds. This inspiration comes from the Canny operator which uses hysteresis for edge thresholding. Furthermore, we expand the hysteresis to be proper for region segmentation in pedestrian detection. Experiments prove that the proposed method performs well most of the time and improves the ability of the pedestrian detection system.

This paper mainly discussed the performance test of the sample hybrid electrical bus on the dynamometer test bench for analyzing the driving ability and the fuel economy. And the fuel economy conversion method of the conventional bus was introduced according to the characteristics of the hybrid electrical vehicle (HEV). In addition, in order to further improve the performance of HEV, the new control strategy was presented on the basis of the primary control algorithm. Finally the bench tests were performed for the diverse drive cycles. The test results show that the hybrid bus can indeed save fuel considerably in diverse drive cycles compared with the similar conventional bus. In particular, in the Beijing city drive cycle the fuel can be saved 30% more than the conventional one, which fully shows the superiority of HEV.
