The invention relates to the technical field of new energy vehicles, and particularly relates to a diesel vehicle keyless system and engine management unit interaction control method. The method comprises the steps that S1, a keyless system judges whether one-key starting switch signal input is received or not, and starts a low-frequency antenna to search a legal intelligent key; S2, the keyless system authenticates the intelligent key; S3, the keyless system judges whether the vehicle meets a starting condition or not; S4, whether an engine is successfully started or not is judged by collecting an engine rotating speed signal. According to the invention, the keyless system can be flexibly suitable for engines of different models and different manufacturers, software adaptation does not need to be conducted according to the different engines, the engine management unit can adapt to a keyless starting vehicle model and a traditional ignition switch vehicle model under the condition thathardware interfaces are not changed, and configuration of the engine management unit is reduced.
本发明涉及新能源汽车技术领域,具体是一种柴油车无钥匙系统与发动机管理单元交互控制方法,S1:无钥匙系统判断是否接收到一键启动开关信号输入,并启动低频天线查找合法的智能钥匙,S2:无钥匙系统对智能钥匙进行认证,S3:无钥匙系统判断车辆是否满足启动条件,S4:通过采集发动机转速信号,判断发动机是否启动成功,本发明无钥匙系统可以灵活适用不同型号,不同厂家发动机而不用根据不同发动机而进行软件适配,发动机管理单元可在硬件接口不做改动的情况下,适配无钥匙启动车型和传统点火开关车型,减少发动机管理单元配置。
