PROBLEM TO BE SOLVED: To detect a plurality of traffic signals and their associated states.SOLUTION: A method includes scanning a target area using one or more sensors of a vehicle 200 to obtain target area information. The vehicle 200 may be configured to operate in an autonomous mode, and the target area may be a type of area where traffic signals are typically located. The method may also include detecting a traffic signal in the target area information, determining a location of the traffic signal, and determining a state of the traffic signal. In addition, confidence in the traffic signal may be determined. For example, the location of the traffic signal may be compared to known locations of a plurality of traffic signals. Based on the state of the traffic signal and the confidence in the traffic signal, the vehicle 200 may be controlled in the autonomous mode.SELECTED DRAWING: Figure 2C
【課題】複数の交通信号及びそれらの関連した状態を検出する。【解決手段】車両200の一つ以上のセンサを用いて目標領域を走査して、目標領域情報を得ることを含む。車両200は自律型モードで操作されるように構成されることがあり、目標領域は交通信号が通常位置する領域の形式であることがある。この方法は更に、目標領域情報内で交通信号を検出し、交通信号の位置を判定し、交通信号の状態を判定することも含み得る。また、交通信号に対する信頼性を判定し得る。例えば、交通信号の位置は、複数の交通信号の既知の位置と比較し得る。交通信号の状態と交通信号に対する信頼性とに基づいて、車両200は自律型モードで制御し得る。【選択図】図2C
