摘要： A steering device, wherein a grip limit control processing (30b') judges whether or not a grip level ɛ estimated by grip level estimation processing (30a) is less than a specified grip level ɛ', and if judged to be less than ɛ', an assist power by the motor (M) is quickly increased to thereby let a driver feel a suddenly lightened steering by a steering wheel and inform the driver that the grip level of the steering wheel is nearing its limit. Accordingly, the probability of skidding to be caused by turning the steering wheel further in the same direction is informed to the driver to call a steering attention to the driver. Therefore, the stability of vehicle behavior can be enhanced without getting the driver feel uneasiness.
摘要翻译：一种转向装置，其中，把持极限控制处理（30b'）判断通过把持水平推定处理（30a）推定的把持水平ɛ是否小于规定的把持水平ɛ'，在判断为小于ɛ' ，马达（M）的辅助动力迅速增加，由此驾驶员感觉到方向盘突然变轻的转向，并通知驾驶员方向盘的把持水平接近其极限。因此，通过将方向盘进一步沿相同方向进一步引起打滑的可能性被通知给驾驶员，以向驾驶员发出转向注意。因此，可以增强车辆行为的稳定性而不会使驾驶员感到不安。

摘要： In a steering apparatus, in accordance with a grip limit control process (30b'), it is determined whether or not a grip degree ε estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree ( ε'), and in the case that it is determined that an estimated grip degree (ε) is less than the predetermined grip degree (ε'), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M) , thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.
摘要翻译：在转向设备中，根据抓地限制控制处理（30b'），确定由抓地程度估计算术运算处理（30a）估计的抓地程度ε是否小于预定抓地程度（ε' ），并且在确定估计抓握程度（ε）小于预定抓握程度（ε'）的情况下，该过程将由方向盘的转向操作突然变轻的这种感觉施加给驾驶员通过马达（M）突然增加辅助量，从而向驾驶员通知转向轮的抓地力度接近极限。因此，通过进一步将转向盘21向与当前方向相同的方向转动而产生侧滑的概率，由此能够向驾驶员传递驾驶员注意转向的可能性。因此，具有可以改善车辆行为的稳定性而不会担心驾驶员不安全的效果。
