PROBLEM TO BE SOLVED: To provide novel steering angle detection device and steering angle detection method by which an amount of data to be processed is reduced and a zero point correction value can be determined in a short time.SOLUTION: When a steering angle differential value for every unit travel distance is a value at which an automobile is deemed to perform straight advance, steering angle information is detected from a steering angle sensor, a most frequent value or an average value of detected plural steering angle information is determined as a zero point correction value, and actual steering angle information from the steering angle sensor is corrected into normal steering angle information by the determined zero point correction value. When the steering angle differential value for every unit travel distance is a value at which the automobile is deemed to perform straight advance, steering angle information from the steering angle sensor is taken in to determine a zero point correction value, whereby an amount of data to be processed is reduced and the zero point correction value can be determined in a short time.SELECTED DRAWING: Figure 7

    【課題】処理すべきデータ量を削減して短い時間で零点補正値を求めることができる新規な操舵角検出装置及び操舵角検出方法を提供することにある。【解決手段】単位走行距離毎の舵角微分値が、自動車が直進走行していると見做される値の時に、舵角センサから舵角情報を検出し、検出された複数の舵角情報の最頻値、或いは平均値を零点補正値として求め、この求められた零点補正値で舵角センサからの実際の舵角情報を補正して正規の舵角情報とする。単位走行距離毎の舵角微分値が、自動車が直進走行していると見做される値の時に、舵角センサの舵角情報を取り込んで零点補正値を求めるようにしているため、処理すべきデータ量が削減されて短い時間で零点補正値を求めることができるようになる。【選択図】図7
