    • An electric power-assist steering system that provides a steering assist control in accordance with the steering angle right after the idle stop to reduce an unpleasant steering feeling and is installed in a vehicle having an idle stop mechanism (engine controller) that automatically performs an idle stop operation in a predetermined condition. The electric power-assist steering system includes a torque sensor, a steering angle sensor for detecting a steering angle relative to a midpoint of a steering angle that is learned, an electric motor whose assist force is controlled based on the steering torque and the steering angle, and a resolver for detecting a rotational angle of the electric motor. A steering angle right after the idle stop is determined based on the steering angle detected by the steering angle sensor right before the idle stop and variation in the rotational angle detected by the resolver during the idle stop.
    • 一种电动助力转向系统,其在怠速停止之后提供根据转向角的转向辅助控制,以减少令人不快的转向感觉,并且安装在具有自动执行空转的怠速停止机构(发动机控制器)的车辆中 在预定条件下停止操作。 电动辅助转向系统包括转矩传感器,用于检测相对于所学习的转向角的中点的转向角的转向角传感器,基于转向转矩和转向角控制辅助力的电动机 以及用于检测电动机的旋转角度的旋转变压器。 基于在怠速停止之前由转向角传感器检测到的转向角以及在怠速停止期间由旋转变压器检测到的旋转角度的变化来确定怠速停止后的转向角。
