EXAMPLE 4: During a given vehicle trip, a user with a Level 4 automated parking feature dispatches the vehicle in driverless operation for the purpose of finding a parking space in a nearby designated parking facility. Following a period of shopping, the user retrieves the vehicle via dispatch in order to begin his/her trip home.
3.7.3 FULL-TRIP FEATURE （full-trip 功能）
ADS features that operate a vehicle throughout complete trips.
可以在整个行驶过程中操作车辆的自动驾驶功能。
EXAMPLE 1: A Level 4 ADS-DV is dispatched in driverless operation for purposes of providing ride-hailing services to customers located within its geo-fenced area of operation.
EXAMPLE 2: A Level 5 dual-mode vehicle is dispatched in driverless operation by its owner to go to a designated airport, pick up several family members, and bring them home. All vehicle occupants remain passengers throughout the return trip.
3.11 FAILURE MITIGATION STRATEGY（故障缓解策略）
A vehicle function (not an ADS function) designed to automatically bring an ADS-equipped vehicle to a controlled stop in path following either: (1) prolonged failure of the fallback-ready user of a Level 3 ADS feature to perform the fallback after the ADS has issued a request to intervene, or (2) occurrence of a system failure or external event so catastrophic that it incapacitates the ADS, which can no longer perform vehicle motion control in order to perform the fallback and achieve a minimal risk condition. (See 8.6.)
一种车辆功能（不是自动驾驶功能），设计用于使搭载了自动驾驶系统的车辆可以在以下路径中被控制停止：（1）L3级自动驾驶系统请求干预，但经过较长的时间后，预备接管用户没有执行接管；或（2）发生了灾难性的系统故障或外部事件，以致于自动驾驶系统无法通过控制车辆动作以执行fallback ，达到最小风险状态。
NOTE: Some vehicles equipped with Level 2 driver support features may be designed to brake a vehicle to a full stop if the driver fails to indicate his/her continued supervision of feature performance during engagement. Although that is similar in function to a failure mitigation strategy as defined above, the term “failure mitigation strategy” is reserved for ADS features that do not require driver supervision.
3.13 FLEET OPERATIONS [FUNCTIONS] （车队运营）
The activities that support the management of a fleet of ADS-equipped vehicles in driverless operation, which may include, without limitation:
在无人驾驶操作中，支持自动驾驶车队管理的活动，包括但不限于：
? Ensuring operational readiness.
? Dispatching ADS-equipped vehicles in driverless operation (i.e., engaging the ADSs prior to placing the vehicles in service on public roads).
? Authorizing each trip (e.g., payment, trip route selection).
? Providing fleet asset management services to vehicles while in-use (e.g., managing emergencies, summoning or providing remote assistance as needed, responding to customer requests and break-downs).
