摘要： The present disclosure provides a method for controlling a rotating speed, a cleaning robot, and a storage medium. The method includes: obtaining the rotating speed of the main brush when the main brush cleans a surface-to-be-cleaned; comparing the rotating speed of the main brush with a predetermined rotating speed; decreasing the rotating speed when the rotating speed is greater than the predetermined rotating speed; or, increasing the rotating speed when the rotating speed is less than the predetermined rotating speed. As such, over-load of an electric motor of the main brush can be avoided, thereby extending the service life of the electric motor. In the meantime, the power consumption by the cleaning robot can be reduced, thereby extending the operation time of the cleaning robot. Furthermore, a satisfying cleaning effect of the cleaning robot can be maintained.

摘要： A method for determining the position of a rotary element of a motor vehicle based on a position sensor configured to measure the position of the rotary element, to simultaneously generate a sine-type output signal and a cosine-type output signal reflecting the angular position of said rotary element as it rotates and to deliver these output signals to a control module of the vehicle, the method, implemented by the control module, including the steps of rotating the rotary element, receiving the output signals generated by the position sensor as the rotary element rotates, determining the average period of the output signals received within a predetermined time range, correcting both received output signals such that the period of each of the signals is equal to the determined average period, and determining the angular position of the rotary element based on the corrected output signals.

摘要： A wheel assembly rotational position identifying apparatus includes an acceleration detector, a control section, and a battery. The control section identifies the rotational position of the wheel assembly based on an acceleration detected by the acceleration detector. The control section operates in a control mode that is a selected one of a normal mode and a power saving mode, in which a power consumption associated with identification of the rotational position of the wheel assembly is smaller than that in the normal mode. The control section switches the control mode to the normal mode when an initiation condition is met in accordance with an input from outside. The control section also switches the control mode to the power saving mode when a termination condition is met in the normal mode.

摘要： A magnetism detecting element detects a leakage magnetism from a scale, on which a magnetic signal with a constant period is recorded, and a relative position between the scale and the magnetism detecting element is detected. The magnetism detecting elements are arranged, along a detection direction of the magnetic signal relative to the scale, in a pattern with a pitch of 1/2n (n is a prime number of 3 or more) of a wavelength λ′ of a signal output by the element. Furthermore, as the pattern for cancelling m odd-order harmonics, the m-th power of 2 magnetism detecting elements are arranged within a range in which a pitch distance L of the magnetism detecting element farthest in the detection direction is expressed by L=(λ′/2)×(1/3+1/5+1/7+ . . . 1/(2m+1)).

摘要： A magnetized scale (1a) in which magnetic pole pairs each formed of a first magnetic portion (11a) and a second magnetic portion (12a) having different magnetic properties are arranged with a period of a magnetic pole pair width 2λ, and a magnetosensitive device (2) in which n magnetosensitive elements (21a to 21e) are arranged with a magnetosensitive element pitch P so that λ=nP may be established are arranged so as to be opposed to each other with a predetermined air gap therebetween. Output values output from the n magnetosensitive elements (21a to 21e) in parallel are analyzed to calculate a relative position between the magnetosensitive device (2) and the magnetized scale (1a) as a position detection resolution of λ/n.
