The invention discloses an engineering machinery transmission system, comprising a walking steering controller configured to output at least two walking steering control quantities; wherein the step of outputting each walking steering control quantity comprises the substeps of obtaining a walking steering reference quantity and a walking steering measurement quantity, and determining a walking steering error quantity according to the walking steering reference quantity and the walking steering measurement quantity; the walking steering error amount serves as input of a first model, and a first control amount is generated through the first model; determining a driving condition, selecting a driving condition reference model matched with the driving condition, and obtaining a walking steering control quantity at a previous moment; the walking steering control quantity at the previous moment serves as input of a currently selected driving condition reference model, and model parameters of a second model are generated; taking the first control quantity as input of a second model, and generating a second control quantity through the second model; and outputting the walking steering control quantity at the current moment by taking the second control quantity as the walking steering control quantity at the current moment.

    本发明公开了一种工程机械传动系统,包括:行走转向控制器,行走转向控制器配置为输出至少两种行走转向控制量;其中,输出每种行走转向控制量包括:获取行走转向参考量、行走转向测量量,根据行走转向参考量以及行走转向测量量确定行走转向误差量;将行走转向误差量作为第一模型的输入,通过第一模型生成第一控制量;确定行驶工况,选定与行驶工况匹配的行驶工况参考模型,获取前一时刻的行走转向控制量;将前一时刻的行走转向控制量作为当前选定的行驶工况参考模型的输入,生成第二模型的模型参数;将第一控制量作为第二模型的输入,通过第二模型生成第二控制量;将第二控制量作为当前时刻的行走转向控制量,输出当前时刻的行走转向控制量。
