Abstract: 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.
