The invention discloses an automatic driving system state control rationality verification method based on functional safety. The method comprises the following steps: S1, system activation; s2, monitoring the state of the main function module in real time; s3, judging whether a fault is true or not, if yes, entering S4, and if not, returning to S2; s4, reading whether the main function module sends out a takeover alarm signal, if so, entering S5, and if not, entering S6; s5, the position of the system state control rationality verification identification is "pass"; s6, the position of the system state control rationality verification identification is not passed; s7, confirming whether verification is passed or not, if yes, entering S8, and if not, entering S9; s8, outputting a take-over alarm signal of the main function module; s9, supplementing and outputting a take-over alarm signal; s10, the HMI alarm module carries out takeover alarm; and S11, if the vehicle is not taken over, returning to S10, if the vehicle is taken over, entering S12, and S12, enabling the automatic driving system to exit. According to the method, the reasonability of state control of the automatic driving system can be accurately verified.

    本发明公开的一种基于功能安全的自动驾驶系统状态控制合理性的校验方法,包括:S1,系统激活;S2,实时监控主功能模块的状态;S3,判断故障是否成立,若是,则进入S4,若否,返回S2;S4,读取主功能模块是否发出接管报警信号,若是,则进入S5,若否,则进入S6;S5,将系统状态控制合理性校验标识位置为“通过”;S6,将系统状态控制合理性校验标识位置为“不通过”;S7,确认校验是否通过,若是,进入S8,若否,进入S9;S8,输出主功能模块的接管报警信号;S9,补充输出接管报警信号;S10,HMI报警模块进行接管报警;S11,若车辆未被接管,则返回S10,若车辆被接管,则进入S12,S12,自动驾驶系统退出。本发明能够准确校验出自动驾驶系统状态控制的合理性。
