The invention discloses an application software torque architecture integrated with an EMS (engine management system) and a VCU (vehicle control unit), which comprises a driver torque domain, a wheel end torque domain, an engine and gearbox torque domain, an execution end torque domain and a torque capacity calculation unit, and is characterized in that the driver torque domain is mainly used for calculating request torque of a driver and then outputting the request torque to the execution end torque domain; the wheel end torque domain receives data transmitted from the driver torque domain and then transmits the data to the engine and gearbox torque domain and the execution end torque domain; the engine and gearbox torque domain receives data transmitted by the wheel end torque domain; the execution end torque domain receives torque requests transmitted by the wheel end torque domain and the engine and gearbox torque domain, and the torque requests are executed through all actuators. The torque capacity calculation unit calculates torques of a driver torque domain, a wheel end torque domain, an engine and gearbox torque domain and an execution end torque domain. The problem that coordination is difficult in the interaction process of the EMS and the VCU can be solved.
本发明公开了一种集成EMS和VCU的应用软件扭矩架构,其包括驾驶员扭矩域、车轮端扭矩域、发动机和变速箱扭矩域、执行端扭矩域、扭矩能力计算单元,驾驶员扭矩域主要是计算驾驶员的请求扭矩,然后输出至执行端扭矩域;车轮端扭矩域接收驾驶员扭矩域传来的数据后,将数据传递给发动机和变速箱扭矩域、执行端扭矩域;发动机和变速箱扭矩域接收车轮端扭矩域传来的数据;执行端扭矩域接收车轮端扭矩域、发动机和变速箱扭矩域传来的扭矩请求,并通过各执行器进行执行;扭矩能力计算单元对驾驶员扭矩域、车轮端扭矩域、发动机和变速箱扭矩域、执行端扭矩域的扭矩进行计算。本发明能解决EMS和VCU交互过程出现协调困难的问题。
