Abstract
A signal information processing device and a signal information processing method for calculating the state of a traffic light for driving assistance for traffic lights for which signal information is not transmitted from a roadside apparatus, and a driving assistance device and a driving assistance method for performing driving assistance on the basis of the calculated state of the traffic light. A driving assistance ECU of a vehicle acquires signal information corresponding to a first traffic light and information indicating the driving environment of the vehicle corresponding to a second traffic light placed at a position different from the first traffic light. The driving assistance ECU is provided with a signal information processing unit, 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 information indicating the driving environment of the vehicle.
