Judgement of steering state of all electrical type power steering device
专利汇可以提供Judgement of steering state of all electrical type power steering device专利检索，专利查询，专利分析的服务。并且PURPOSE:To obviate the need of a steering angle sensor by searching the between-motor terminal voltage value in the steering holding state from the indication value of the motor electric current and judging the steering state from the difference between the actual between-motor terminal voltage value. CONSTITUTION:The indication value and direction of the motor electric current are calculated in a CPU 4 from the handle torque detected by a torque sensor 1 and the car speed detected by a car speed sensor 3, and a motor 18 is controlled according to the results of the calculation. When the motor 18 is in revolution, the between-terminal voltage VM of the motor is detected, and the between-terminal voltage VMSET of the motor in the steering holding state for the above-described indication value of the motor is calculated. The both voltage values VM and VMSET are compared, and if VM>VMSET, and the value VM-VMSET is larger than V, the cut-in state is judged, and if the value VM-VMSET is smaller than V, the steering holding state is judged. Further, when VM，下面是Judgement of steering state of all electrical type power steering device专利的具体信息内容。
