The invention discloses a vehicle driving mode control method and system and a vehicle, a power system PCU controller is used as a core algorithm carrier, and the voltage of a first driving mode switch, the voltage of a second driving mode switch and an HU driving mode target are input; the power system PCU controller is used for BSW-level digital or analog signal processing, ASW-level signal processing, first driving mode switch and second driving mode switch fault judgment, fault processing, input signal anti-shake processing, mode switch request validity judgment, mode switch request state judgment, driving mode state judgment and driving mode output de-shake processing. According to the method, the fault state of the driving mode switch can be judged and processed, the situation that the whole function cannot be normally used due to the fact that a certain switch breaks down is avoided, the algorithm is rigorous, and the reliability of driving mode selection is improved.

    本发明公开一种车辆驾驶模式控制方法、系统和车辆,以动力系统PCU控制器为核心算法载体,输入为第一驾驶模式开关的电压、第二驾驶模式开关的电压和HU驾驶模式目标,动力系统PCU控制器为BSW层级数字或模拟信号处理、ASW层级信号处理、第一驾驶模式开关和第二驾驶模式开关故障判断、故障处理、输入信号防抖处理、模式开关请求有效判定、模式开关请求状态判定、驾驶模式状态判定及驾驶模式输出去抖处理。该方法能够对驾驶模式开关进行故障状态的判断和处理,避免了因某个开关出现故障导致整个功能均无法正常使用,算法严谨,提升了驾驶模式选择的可靠性。
