ISO/TR 12204:2012提供了将安全关键和时间关键警告信号（即使短暂忽略，也可能导致车辆乘员和/或其他道路使用者身体伤害的信号）整合到现有车内信息中的一般性信息指南，该信息提供给驾驶员。非关键信号的集成不在ISO/TR 12204:2012的范围内，除非确认它们不会影响驾驶员对安全和时间关键信号的理解。 ISO/TR 12204:2012规定: 1） 确定是否需要集成以降低来自一个或多个车辆系统的信号可能会降低驾驶员对来自另一个系统的安全关键警告信号的理解或响应的可能性的可能方法； 和 2） 讨论评估潜在整合冲突的可能方法。

ISO/TR 12204:2012 provides general, informative guidance for the integration of safety critical and time critical warning signals (signals which, if ignored even briefly, could result in bodily harm to the occupant(s) of the vehicle and/or to other road users) into existing in-vehicle messages presented to a driver. Integration of non-critical signals are outside the scope of ISO/TR 12204:2012, except to confirm that they do not affect the driver's comprehension of safety and time critical signals. ISO/TR 12204:2012 provides: 1) possible approaches for determining if integration is necessary to mitigate the possibility that signals from one or more vehicle system may degrade the driver's comprehension of, or response to, safety critical warning signals from another system(s); and 2) a discussion of possible methods for assessing potential integration conflicts.
