An apparatus and a method for controlling rear wheel steering are provided. The apparatus includes a turning state estimator that acquires steering angle information from a steering angle sensor and estimates a turning state by calculating a required steering speed from the steering angle information. A normal state lateral acceleration predictor predicts a normal state lateral acceleration to match the required steering speed in response to determining that the required steering speed is equal to or greater than a speed threshold value. A rear wheel steering angle calculator calculates a rear wheel steering angle based on the steering angle and the lateral acceleration.
本发明涉及用于控制后车轮转向的装置及方法。所述装置包括转弯状态估算器,其从转向角传感器获取转向角信息,并且通过从转向角信息计算所需的转向速度来估算转弯状态。正常状态横向加速度预测器响应于确定出所需的转向速度大于或等于速度阈值来预测正常状态横向加速度,以匹配所需的转向速度。后车轮转向角计算器基于转向角和横向加速度来计算后车轮转向角。
