摘　　要：混合动力是当前商用车动力系统前沿技术之一.文中构建了某商用车轻度混合动力系统,采用AVISOR将轻度混合动力商用车和传统商用车的燃油经济性、动力性和排放特性进行了仿真对比分析.基于湖北省某道路工况,较之传统商用车:最大加速度提高3%;总耗油量节省1.61%,发动机平均热效率提高1.1%;NO\-x排放量降低1.5%,制动回收的能量占刹车能量的16%.Hybrid power is one of the leading technologies in commercial vehicle power system. In this paper, a light hybrid power system of a commercial vehicle was constructed, and the fuel economy, power and emission characteristics between the light hybrid commercial vehicle and the traditional commercial vehicle were simulated and compared with AVISOR. Based on a road condition in Hubei Province, compared with traditional commercial vehicles, the maximum acceleration is increased by 3%. The total fuel consumption is saved by 1.61%, and the average thermal efficiency of the engine is increased by 1.1%. NOx emission is reduced by 1.5%, and braking energy recovered accounts for 16% of braking energy.
