摘要 为提高城市电动客车并联再生制动策略的制动稳定性与制动能回收量,分析了电动客车制动稳定性要求对机电并行再生制动时制动能回收率的影响。根据欧洲经济委员会第13号制动法规(regulation No.13of the Economic Commission for Europe,简称ECE R13)要求,利用广义制动力分配线与广义理想制动力分配曲线的位置关系,结合电动客车在典型城市工况下的运行特征,将机电并行制动的制动强度确定在0.1与0.3之间;在机电并行制动时,利用惯性比例阀将机械制动系制动力分配比调整为ECE R13法规许可的最大值。对advisor2002电动汽车仿真软件进行了二次开发,建立了后驱型电动汽车仿真模型。仿真表明新策略使城市电动客车在典型城市工况下的制动能回收量得到了明显提高。 With aims of improving braking stability and the capability of capturing braking energy of an electric urban bus with parallel regenerative braking strategy,the influence on the reclaiming efficiency of braking energy under the braking stability demand is analyzed. Following ECE R13 and using the positional relation between generalized braking force distribution line and generalized expected braking forcedistribution curve, the braking intensity of electro-mechanical parallel braking under parallel braking strategy is determined between 0. 1 and 0. 3 with a consideration on engineering practices of an electric urban bus. Braking force distribution ratio of a mechanical braking system system during electro-mechanical parallel braking is adjusted to maximum within the regulation permissible range by inertia proportional valve. ADVISOR2002 is redeveloped to build a simulation model of a rear-wheel-drive electric vehicle. Simulation results with this strategy show a significant improvement of an electric urban bus braking energy reclaiming performance under the typical urban driving cycles conditions.
