Abstract

A vehicle window assembly and a vehicle are provided. The vehicle window assembly includes a vehicle window glass, at least two sensors, and a heating component. The vehicle window glass has a functional region. At least two signal transmission windows are defined at intervals in the functional region. The at least two sensors are mounted at an inner side of the vehicle window glass. Positions of the at least two sensors are in a one-to-one correspondence with positions of the at least two signal transmission windows. The heating component includes at least one linear heating element. At least one signal transmission window of the at least two signal transmission windows is extended through by the at least one linear heating element multiple times. At least another signal transmission window of the at least two signal transmission windows is not extended through by the at least one linear heating element.
