摘要
提出了基于两参数动力性换挡规律自动变速器的全时四驱汽车特种工况牵引力控制策略。建立了全时四轮驱动汽车整车模型和传动系统模型,设计了软件在环仿真平台,进行了特种工况下的仿真。结果表明,所设计的控制策略显著提高了车辆在低坡度分离路面上和对接路面上起步加速时的地面牵引力和变速器挡位。
Traction control strategy under special conditions of full-time 4WD vehicle based on the AMT of two parameters dynamic gear-shift law was proposed.A full-time four-wheel-drive vehicle model and the transmission system model were established.In-the-loop simulation platform software were designed.The simulation results under the special conditions show that the designed control strategy significantly improves the vehicle s ground traction and transmission shift when starting to accelerate in low-slope from th...
