摘要： 重卡坡道起步辅助控制与起步操作时的路况特征不匹配时，整车驾驶感受差异较大。 文章以重卡自动变速器（AMT）车型为研究对象，增加坡道起步自适应控制机制识别整车状 态，提出了一种基于整车典型工况在坡道辅助起步过程中准确辨识整车阻力及时解除制动的 方法，满足不同工况下在合适的时机解除整车制动。试验表明，该方法能满足驾驶员在生产 工作中的使用需求，通过仿真及实车验证，重卡在坡道起步过程中，能及时解除制动，起步 过程驾驶感受明显提升，满足驾驶员需求。

Abstract: When the heavy-duty truck hill-start assist control strategy does not match the road condition characteristics during start-up operation, the vehicle driving experience varies significantly. This paper takes heavy-duty trucks equipped with automated manual transmissions (AMT) as the research object, introduces an adaptive control mechanism for hill-start to identify vehicle states, and proposes a method to accurately estimate vehicle resistance and release the brake at an appropriate timing during hill-start assistance based on typical vehicle operating conditions. Tests have shown that this method meets the operational needs of drivers in practical production work. Through simulation and real-vehicle verification, the heavy-duty truck can release the brake in a timely manner during hill-start, the driving experience during start-up is significantly improved, and the driver's requirements are fully satisfied.
