    摘要:

    針對(duì)牽引力控制系統(tǒng)門限值壓力控制策略容易產(chǎn)生控制超調(diào)的缺點(diǎn),，提出基于路面條件判斷的壓力控制策略,。利用輪速信號(hào)進(jìn)行路面條件判斷,，針對(duì)不同路面條件提出不同的壓力控制目標(biāo),，計(jì)算需要的目標(biāo)壓力并估算實(shí)際的干涉壓力。實(shí)車試驗(yàn)結(jié)果表明：該控制策略可以大大減小制動(dòng)力矩與發(fā)動(dòng)機(jī)驅(qū)動(dòng)力矩的無謂對(duì)耗,，能夠有效減少壓力波動(dòng)及輪速波動(dòng),，在對(duì)開路面上汽車的起步加速能力提高了

    Abstract:

    47%。One pressure control strategy was presented for traction control system (TBS). Wheel speed sensor signals were used to judge road condition; different pressure control aims were suggested for different road conditions; target pressure was calculated and real pressure was estimated. The strategy was confirmed with vehicle experiment. The result showed that this pressure control strategy could greatly reduce the meaningless consumption of engine torque by the brake torque. The strategy could greatly reduce the fluctuation of pressure and the wheel speed fluctuation resulting from pressure fluctuation; it could also improve the vehicle starting ability up to 47%. 
