摘要： A slip control device for an electric vehicle which errorlessly determines slippage occurrence with only a rotation angle sensor for motor rotation control and perform rapid control to eliminate the slippage, is provided. A threshold calculator 21 calculates a normal angular acceleration of a motor depending on a manipulation amount of an accelerator to obtain a threshold, and an angular acceleration calculator 22 differentiates a detection value from a rotation angle sensor 3a twice to calculate an angular acceleration. A slip determination 23 determines whether a wheel 7 driven by a motor 3 has slipped, and a torque limitation 25 limits a torque when determining a slippage. The determination 23 compares the calculated acceleration to the threshold, counts a number of times it is consecutively determined that the calculated acceleration exceeds the threshold, and determines a slippage if the number of times has reached a set value.

摘要： In a locking type reverse input blocking clutch of the present invention, smooth finished surfaces having no directionality are formed, by barrel polishing, on surfaces brought into contact with rollers (10) while rotation is being transmitted from the input side to the output side, i.e. an inner peripheral cylindrical surface of an outer ring (5) and a surface of a lid portion (6b) opposed to the rollers (10). With this arrangement, it is possible to reduce the sliding resistance between the rollers (10) and the outer ring (5) and between the rollers (10) and the lid portion (6b), without the need to reduce the forces of springs (11) for pushing the rollers (10) into narrow portions of wedge-shaped spaces (14). This in turn makes it possible to reduce the torque necessary to transmit rotation from the input side to the output side, while maintaining high locking performance.
摘要翻译：在本发明的锁定式反向输入闭锁离合器中，通过滚筒抛光，在从输入侧向输出侧传送旋转的同时，在与辊（10）接触的表面上形成没有方向性的光滑的成品表面，即外圈（5）的内圆周表面和与辊（10）相对的盖部分（6b）的表面。通过这种布置，可以减少辊（10）和外圈（5）之间以及辊（10）和盖部（6b）之间的滑动阻力，而不需要减小弹簧的力（ 11），用于将辊（10）推入楔形空间（14）的狭窄部分。这又可以降低从输入侧向输出侧传递旋转所需的转矩，同时保持高的锁定性能。

摘要： The rotation detection device includes: an encoder having to-be-detected patterns cyclically arranged in the circumferential direction; and a sensor configured to detect the to-be-detected patterns to generate pulses. The device further includes a reference pattern storage unit, a phase difference detection unit, and an error correction unit. The reference pattern storage unit measures pitch errors in the to-be-detected patterns prior to operation and stores the pitch errors as a reference pattern Pref. The phase difference detection unit determines a pitch error pattern Pm corresponding to one rotation of the to-be-detected patterns from rotation signals representing a plurality of rotations detected during operation, and performs comparison with a reference pattern Pref to determine a relative phase difference Æ. Based on the phase difference Æ obtained by the phase difference detection unit, the error correction unit corrects errors included in the rotation signals detected by the sensor.
