The invention discloses a user-defined steering wheel key function system which comprises a single-chip microcomputer control unit, a vehicle-mounted control system, a display module, a target control unit and a steering wheel key set, the steering wheel key set is an output circuit formed by parallel connection and series connection, and the single-chip microcomputer control unit uses an MCU with a CAN bus as a main control chip. An ADC of a main control chip is used for identifying keys, a serial port of the main control chip is communicated with a vehicle-mounted control system, a CAN bus is communicated with a target control unit, the vehicle-mounted control system is used for processing key values and function states reported by the serial port and controlling a display module, the display module displays controllable functions and keys on a corresponding steering wheel, and the vehicle-mounted control system is connected with the main control chip. And the target control unit receives and sends an instruction and executes the instruction through the CAN bus. The problem that the keys of the steering wheel are fixed is solved, and the problem that automobile software upgrading and function increasing cannot be controlled can be effectively solved.

    本发明公开了一种用户自定义的方向盘按键功能系统,包括单片机控制单元、车载控制系统、显示模块、目标控制单元以及方向盘按键组,方向盘按键组是由并联和串联组成的输出电路,单片机控制单元由具有CAN总线的MCU作为主控芯片,使用主控芯片的ADC来识别按键,主控芯片的串口与车载控制系统通讯,CAN总线与目标控制单元通讯,车载控制系统用于将串口上报的按键值和功能状态进行处理操作,并控制显示模块,显示模块显示可控制的功能和显示对应方向盘上的按键,目标控制单元通过CAN总线接收和发送指令以及执行指令。本发明解决了方向盘按键固定式的弊端,能有效的解决汽车软件升级,功能增加而无法控制的问题。
