The invention provides a driving assistance apparatus, a driving assistance method, and a storage medium. A driving assistance device is provided with: a traffic signal device recognition device that recognizes the light pattern of a traffic signal device present in front of a host vehicle; and a control device that determines a predetermined position in the vicinity of the traffic signal device as a target position and performs deceleration control for decelerating the host vehicle until the host vehicle reaches the target position. A predicted speed, which is the speed of the host vehicle at a point in time at which the host vehicle arrives at the target position when decelerating the host vehicle in a predetermined deceleration pattern from the current point in time, is calculated, and deceleration control is performed in a first condition in which the predicted speed is less than a threshold value determined on the basis of the light pattern of the traffic signal device. The deceleration control is not performed in a second condition in which the predicted speed exceeds the threshold value. When the light color of the traffic signal device is red, the threshold value when the light color of the traffic signal device is yellow is smaller than the threshold value when the light color of the traffic signal device is red.

    本公开提供一种驾驶辅助装置、驾驶辅助方法以及存储介质。驾驶辅助装置具备:交通信号器识别装置,其对存在于本车辆前方的交通信号器的灯光形态进行识别;控制装置,其将交通信号器的周边的预定位置决定为目标位置,并执行使本车辆减速的减速控制直至本车辆到达目标位置为止,且被构成为,对作为在从当前时间点起使本车辆以预定的减速形态而减速的情况下到达目标位置的时间点的本车辆的速度的预测速度进行运算,在预测速度小于基于交通信号器的灯光形态而决定的阈值的第一状况下执行减速控制,在预测速度超过阈值的第二状况下不执行减速控制。与交通信号器的灯光颜色为红色的情况下的阈值相比,交通信号器的灯光颜色为黄色的情况下的阈值较小。
