摘要： A technique can include receiving, at a controller for a vehicle, the controller including one or more processors, a signal indicative of a pressure in an intake manifold of an engine of the vehicle. The vehicle can include a supercharger configured to supply pressurized air to the intake manifold. The supercharger can be driven by a crankshaft of the engine via a belt. The technique can include estimating, at the controller, a frequency of the signal to obtain an estimated frequency. The technique can include determining, at the controller, whether the belt is slipping based on a comparison between the estimated frequency and a predetermined frequency. The technique can also include outputting, at the controller, a notification when the belt is determined to be slipping.

摘要： A control module of a vehicle comprises a drive diagnostic module and a power determination module. The drive diagnostic module determines a slip power of a belt based on engine speed, motor speed, and motor torque. The power determination module determines an accumulated power of the belt based on the slip power, the motor speed, and the motor torque. The control module diagnoses a condition of the belt based on the accumulated power.

摘要： A power transmission device includes: a first pulley; a second pulley having a diameter equal to or larger than a diameter of the first pulley; a belt wound around the first pulley and the second pulley; and a detection unit configured to detect a displacement of the belt in a direction intersecting the surface of the belt. The detection unit is configured to detect the displacement of the belt at a predetermined measuring point. The distance from the border between a portion where the belt and the first pulley are in contact with each other and a portion where the belt and the first pulley are not in contact with each other, to the measuring point is equal to or smaller than the diameter of the first pulley.

摘要： A pulley has evenly spaced grooves. A belt is formed with evenly spaced teeth which mesh with the grooves on the pulley. A device senses deformation of the belt resulting from damage to at least one of the teeth on the belt. The device may sense an opening between the belt and the pulley which results from breakage of at least one of the teeth on the belt. When such displacement or an opening is detected, an indicator lamp is lit to report that the belt should be replaced.

摘要： In combination with a belt tensioner which includes an idler pulley to be radially displaced under control of an actuator for applying an tensioning force on an endless belt of the drive system for the vehicle accessories, an electric control apparatus comprises a microcomputer for calculating the actual tensioning force on the belt related to radial displacement of the idler pulley and for calculating drive power necessary for driving the vehicle accessories to calculate total drive torque of the vehicle accessories in relation to rotational speed of a prime mover of the vehicle. The microcomputer also calculates an optimum tensioning force based on a desired relationship between the optimum tensioning force and the total drive torque in consideration with the maximum efficiency of power transmission of the belt such that it generates a control signal when the calculated actual tensioning force is different from the calculated optimum tensioning force. An electrically operated drive mechanism is responsive to the control signal from the microcomputer to operate the actuator in accordance with the difference between the calculated actual and optimum tensioning force.
