Vehicle travelling prediction method, vehicle travelling prediction device and on-board smart system

A vehicle travelling prediction device, comprising:

• a traffic light determination unit configured to determine a state of a traffic light;
• an acquisition unit configured to acquire a first distance between a current vehicle and an intersection where the traffic light is located in an advancing direction of the current vehicle, and when the traffic light is in a first state where the current vehicle is allowed to cross the intersection, acquire a first time period t1 within which the traffic light is changed to be in a second state where the current vehicle is not allowed to cross the intersection and acquire a detection result of a vehicle in a same lane, the detection result of the vehicle in the same lane comprising a detection result of a vehicle behind the current vehicle and/or a detection result of an obstacle vehicle;
• and
• an output unit configured to output a prediction result indicating whether or not the current vehicle is capable of crossing the intersection in accordance with the first time period t1, the first distance and the detection result of the vehicle in the same lane.
