The invention discloses a control method for avoiding misoperation of a multifunctional switch of an automobile steering wheel. The method comprises the following steps that: S1, a steering wheel multifunctional switch sends an LIN signal to a multimedia host module through a steering wheel LIN module, the multimedia host module converts the multifunctional switching signal of the steering wheel into a CAN signal and sends the CAN signal to a CAN bus; an instrument host module and an engine ECU obtain a steering wheel multifunctional switch signal from the CAN bus, a corner sensor module sendsa corner signal to the CAN bus, and the engine ECU sends a vehicle speed signal to the CAN bus; and S2, the multifunctional switch of the steering wheel directly sends a hard wire signal to the multimedia host module, the instrument host module and the engine ECU, and the engine ECU sends the vehicle speed signal to the CAN bus. According to the control method, the cost is low, a driver is prevented from mistakenly operating the multifunctional switch of the steering wheel in the turning driving process, the attention of the driver in the turning process is improved, and the driving safety ofthe automobile is improved.
本发明公开了一种避免汽车方向盘多功能开关误操作的控制方法,包括以下步骤:S1:方向盘多功能开关通过方向盘LIN模块发送LIN信号到多媒体主机模块,多媒体主机模块将方向盘多功能开关信号转化为CAN信号发送到CAN总线上,仪表主机模块、发动机ECU从CAN总线上获取方向盘多功能开关信号,转角传感器模块发送转角信号到CAN总线上,发动机ECU发送车速信号到CAN总线;S2:方向盘多功能开关直接发送硬线信号到多媒体主机模块、仪表主机模块、发动机ECU,发动机ECU发送车速信号到CAN总线上,本发明用较低的成本,避免了驾驶员在转弯行驶时误操作方向盘多功能开关,提高了驾驶员转弯过程中的注意力,提升了车辆行驶安全性。
