<p>Provided are a signal information processing device for a vehicle and a signal information processing method for a vehicle capable of calculating the state of a traffic light for driving assistance for traffic lights for which signal information is not transmitted from a roadside apparatus, as well as a driving assistance device and a driving assistance method for performing driving assistance for a vehicle on the basis of the calculated state of the traffic light. A driving assistance ECU (30) of a vehicle (10) processes signal information in which information related to the state of a traffic light is included. The driving assistance ECU (30) of the vehicle (10) acquires signal information corresponding to a first traffic light and acquires information indicating the driving environment of the vehicle (10) corresponding to a second traffic light placed at a position different from the first traffic light. In addition, the driving assistance ECU (30) is provided with a signal information processing unit (31), which estimates signal information of the second traffic light by performing a computation on the basis of the signal information corresponding to the first traffic light and the acquired information indicating the driving environment of the vehicle (10).</p> |
