1、ZF 4HP16 自动变速箱,换档模式(模糊逻辑) 经济模式/中间模式/运动模式 负载1 /负载2 /负载3(上坡/上陡坡/下坡) 换档禁止 (wheel slipping),ZF 4HP16 自动变速箱,HOLD键,保 持 模 式 如果保持模式开关被按下,变速箱将从2档起步. D range -2,3,4 3 range - 2,3 2 range 2 1 range - 1,保 护 模 式 当TFT达到140摄氏度时,TCM进入”保护模式”以减少油温 的升高,在保护模式下TCM会限制TCC的滑差率,并且将2-3,3-4 的换档提前,以减少油液发热量.,紧 急 模 式 当在D,3,2,1档位
