Abstract
A driver assistance device to be disposed in a vehicle includes a traffic signal information acquiring section, an intersection distance acquiring section, a target speed calculating section, and an outputting section. The traffic signal information acquiring section acquires traffic signal information that includes current and future lighting colors and lighting times of respective lighting colors of a traffic signal located in a traveling direction of the vehicle. The intersection distance acquiring section acquires an intersection distance between the vehicle and an intersection at which the traffic signal is located. The target speed calculating section calculates a target speed range to enable the vehicle to enter the intersection in a state where the lighting color of the traffic signal is green. The outputting section outputs the target speed range.
