The invention relates to an engine and gearbox coordination control method and device, computer equipment, a computer readable storage medium and a computer program product. The method comprises the steps that under the condition that a temperature rise request signal transmitted by an engine controller is received, gear information is obtained through a gearbox; the temperature rise request signal is generated under the condition that the engine controller monitors that the temperature of the aftertreatment system is smaller than a temperature threshold value; according to the gear information and a calibrated engine universal characteristic curve, the corresponding relation between gear change and temperature change is determined; and under the condition that it is determined that the gear change can enable the temperature to rise, a corresponding gear shifting command is generated and sent to a gearbox controller so as to instruct the gearbox controller to control a gearbox to execute gear shifting according to the gear shifting command. By the adoption of the method, the AMT can be used for participating in engine thermal management, the influence of thermal management on engine oil consumption is reduced to the maximum extent, and the engine oil consumption is reduced on the basis that the exhaust efficiency of the diesel engine is guaranteed.

    本申请涉及一种发动机及变速箱协调控制方法、装置、计算机设备、计算机可读存储介质和计算机程序产品。所述方法包括:在接收到发动机控制器传输的升温请求信号的情况下,通过变速箱获取档位信息;升温请求信号是发动机控制器在监测到后处理系统温度小于温度阈值的情况下生成的;根据档位信息和标定的发动机万有特性曲线,确定档位变化与温度变化之间的对应关系;在确定档位变化能够使温度升高的情况下,生成并发送相应的换挡命令发送至变速箱控制器,以指示变速箱控制器根据换挡命令控制变速箱执行换挡。采用本方法能够利用AMT参与发动机热管理,最大程度减小热管理对发动机油耗的影响,保证柴油发动机排温效率的基础上,降低发动机油耗。
