The invention provides a combination instrument all-terrain driving mode switching display method, which comprises the following steps that S1, a driving mode switching switch is operated, and the switch sends a signal to a mode acquisition ECU (Electronic Control Unit); s2, the mode acquisition ECU sends an acquisition signal to an arbitration ECU and a display ECU combination instrument; s3, the arbitration ECU sends the target mode of the collection ECU to the execution ECU; s4, after each execution ECU receives the signals of the arbitration ECU, handshake, processing and feedback are completed; and S5, in the process that the instrument completes the S2, the S3 and the S4 are completed in advance, the arbitration ECU inputs a final arbitration result to the instrument, and the instrument displays a final state after comparing the target signal of the acquired ECU and the final signal. According to the invention, the acquisition ECU transmits the signal to the terminal display ECU in advance, prompts a user of the current switching effect in the target switching process, covers the arbitration process, reduces part of logic processing of the arbitration ECU, improves the switching timeliness, and achieves the purposes that the response speed is high and the fault phenomenon is not easy to perceive.
本发明提供了一种组合仪表全地形驾驶模式切换显示的方法,包括以下步骤:S1、操作驾驶模式切换开关,开关将信号发送给到模式采集ECU;S2、模式采集ECU将采集信号发送给仲裁ECU以及显示ECU组合仪表;S3、仲裁ECU将采集ECU的目标模式发送给执行ECU;S4、各执行ECU接受仲裁ECU信号后,完成握手及处理并反馈;S5、仪表在完成S2的过程中,S3及S4提前完成,仲裁ECU将最终仲裁结果输入给仪表,仪表再与采集ECU的目标信号及最终信号做比对后显示最终状态。本发明的采集ECU提前将信号传递到终端显示ECU,在目标切换的过程中就提示用户当前切入效果,覆盖仲裁过程,减少了仲裁ECU部分逻辑处理,提升了切换时效,达到反应速度快及故障现象不易察觉的目的。
