Provided is a feature capable of improving a steering feeling in an electric power steering control device. This electric power steering control device is provided with: a base control amount calculation unit (611) that calculates a base control amount corresponding to steering by a driver; a friction force calculation unit (612) that calculates a friction force corresponding to at least one of the yaw velocity and the lateral acceleration by using a friction model, and calculates a friction-causing control amount obtained from the calculated friction force; and a control amount calculation means that calculates a steering control amount on the basis of the base control amount and the friction-induced control amount.
提供了一种在电动助力转向控制装置中能够改善转向感的特征。该电动助力转向控制装置设置有:基础控制量计算单元(611),其计算与驾驶员的转向相对应的基础控制量;摩擦力计算单元(612),其通过使用摩擦模型计算与横摆角速度和横向加速度中的至少一者相对应的摩擦力,并且计算从计算出的摩擦力获得的摩擦起因控制量;以及控制量计算单元,其根据基础控制量和摩擦起因控制量计算转向控制量。
