The invention discloses an automatic parking activation monitoring method and device conforming to functional safety, and the method comprises the steps: collecting the speed of a vehicle in real time, carrying out the real-time comparison and calculation of a speed value through a main controller, and judging a calculation result; averaging the wheel speed and the shaft speed of the gearbox in real time through a main controller and a monitor, and judging a calculation result; speed threshold ranges for normal starting of the automatic parking function are set in the main controller and the monitor respectively, judgment is carried out according to the average value, and a judgment result A and a judgment result B are obtained; comparing the judgment result A with the judgment result B to obtain a final judgment result, and outputting an activation signal or an error signal according to the final judgment result; when any error signal is output, the automatic parking function is closed, and a safe state is entered; according to the invention, centralized monitoring of automatic parking activation is realized, and the requirements of corresponding function safety levels are met, so that the complexity and the cost of a monitoring system are reduced, and system application with function safety requirements can be met.
本发明公开了一种符合功能安全的自动泊车激活监控方法及装置,方法包括:实时采集车辆的速度,通过主控制器对速度值进行实时比较和计算,判定计算结果;通过主控制器和监控器分别实时对轮速和变速箱轴速求平均,判定计算结果;在主控制器和监控器中分别设定自动泊车功能正常开启的速度阈值范围,根据平均值进行判定,得到判定结果A和B;对判定结果A和判定结果B进行比较,得到最终判定结果,根据最终判定结果输出激活信号或错误信号;当输出任何错误信号时,关闭自动泊车功能,进入安全状态;本发明实现了自动泊车激活集中式的监控,实现了相应功能安全等级的要求,从而降低了监控系统的复杂度和成本,并能够满足功能安全要求的系统应用。
