The invention relates to the technical field of electric vehicles, in particular to a software compatibility control method for an extended-range electric vehicle, and the method comprises the steps: carrying out the writing configuration of vehicle model information through offline brushing and writing work, transmitting the vehicle model information to VCU bottom software, transmitting the vehicle model information to an application layer through the VCU bottom software, and carrying out the recognition decision and execution through the application layer; the vehicle configuration information is sent out by the central gateway TBOX, the VCU selects to switch different configurations of the same vehicle type according to the vehicle configuration information sent out by the TBOX, different control strategies required by the same function are determined according to different configurations, and the problem that software of different versions appears in the VCU due to different configurations at the present stage, and the control strategy is required is solved. And different versions of software have high difficulty in development, testing, performance calibration, software version management, maintenance and upgrading of the VCU software, and high development cost and maintenance cost.
本发明涉及电动汽车技术领域,具体地说,本发明涉及一种增程式电动汽车软件兼容控制方法,车型信息由下线刷写工作进行写配置传递至VCU底层软件,VCU底层软件将车型信息传递至应用层,应用层进行识别决策和执行;整车配置信息则由中央网关TBOX负责发出,VCU根据TBOX发出的整车配置信息来选择切换同一车型的不同配置,根据不同的配置决定同一功能需要不同的控制策略,解决了现阶段对于不同配置也就造成了VCU出现了不同版本的软件,而不同版本的软件对于VCU软件的开发、测试、性能标定以及软件版本管理和维护升级难度较高,开发成本以及维护成本较高的问题。
