无人驾驶汽车的发展正强调需要强大的,低延迟的无线通信,以提供广泛的功能。有两种不同的方法被提出,为了满足这一需要,802.11p和c-v2x:PC5。
无线通信可以从车辆到基础设施(V2I),车辆(V2V)和车辆行人(V2P),所有组合为V2X。
Standardization has also been a key issue to allow volume production of wireless transceivers to reduce costs and ensure that vehicles can operate safely in many different markets around the world. This has also raised issues for both sets of technologies.
While the different approaches may seem to be in competition, the application of the technologies depends on the use cases and the level of interaction that is needed for a particular type of autonomous vehicle. For example, an autonomous truck may have a more limited set of interactions from a taxi that would connect directly to a customer’s cellphone.
