The invention discloses an automobile gear display system. The system comprises a gear shifting mechanism, a controller, an automobile instrument and an engine ECU, wherein the controller is in communication connection with the automobile instrument through a CAN bus; the gear shifting mechanism comprises a shift push rod, a shift rocker arm, a magnet and a Hall acquisition element, wherein the Hall acquisition element is used for acquiring a Hall signal, and the Hall acquisition element comprises a Hall switch A, a Hall switch B, a Hall switch H1, a Hall switch H2 and a Hall switch H3; and two magnets are arranged on the gear shifting push rod and the gear shifting rocker arm respectively. According to the system, the current gear position of a manual gear is directly displayed on the instrument through an acquisition circuit, so that a driver can know the current gear information very intuitively and make corresponding vehicle control actions, in particular in the parking state afteran engine is turned off, the gear uncertainty condition is avoided.

    本发明公开了一种汽车档位显示系统,包括换挡机构、控制器、汽车仪表和发动机ECU;所述控制器与汽车仪表之间通过CAN总线进行通信连接;换挡机构包括换档推杆、换档摇臂、磁铁和霍尔采集元件,所述霍尔采集元件用于采集霍尔信号,所述霍尔采集元件包括霍尔开关A、霍尔开关B、霍尔开关H1、霍尔开关H2和霍尔开关H3;所述磁铁为两个,分别设置于换挡推杆和换挡摇臂上;本发明通过采集电路将手动档的当前档位直接显示到仪表上,驾驶员可以很直观的了解到当前的档位信息并做出相应的车辆控制动作。特别是发动机熄火后的停车状态下,避免了档位不确定情况。
