A vehicle communication access framework and a method are provided. The vehicle communication access framework comprises: a first device residing in a vehicle, a first processing system operated by a trusted third party, a second processing system operated by an original equipment manufacturer (OEM) of the vehicle, and a third processing system operated by a third party provider; wherein communication accesses among the first device, second processing system and third processing system are based on Identity Based Cryptography (IBC) private keys generated by the first processing system to respective first device, second processing system and third processing system.

Securing outside-vehicle communication using IBC

A collision warning method and a collision warning apparatus are disclosed. The method includes: obtaining a target deceleration and a target distance headway of a first vehicle by training based on historical travel data of the first vehicle, obtaining a TTC of the first vehicle and a leading vehicle, and determining, based on a comparison between the TTC and a first threshold, whether to send warning information. Because the target deceleration and the target distance headway of the first vehicle can reflect personal driving habit characteristics of a driver of the first vehicle, the TTC obtained based on the historical travel data is highly adaptable, thereby effectively resolving a problem of low warning effectiveness that is caused by a unified deceleration and a unified distance headway in the prior art.
