摘要： A method of operating an accessory drive system for a motor vehicle, wherein the accessory drive system includes one or more accessory components, a motor generator of the motor vehicle, and a flexible drive element configured to transmit a torque load between the one or more accessory components and the motor generator, includes determining a maximum permissible flexible drive element torque threshold, detecting an increase in torque demand on the flexible drive element, determining when the torque demand on the flexible drive element will exceed the flexible drive element torque threshold, and reducing the torque demand of one or more of the accessory components so that the flexible drive element torque threshold is not exceeded.

摘要： A hydraulic system includes a normally open-type hydraulic clutch which connects or disconnects a power transmission line between an engine and a wheel, an actuator which supplies a hydraulic pressure to the hydraulic clutch, an oil flow path which connects the actuator to the hydraulic clutch, a valve member which is provided on the oil flow path and which enables to switch between an open state where the oil flow path communicates and a closed state where the oil flow path closes, a hydraulic pressure sensor which is provided on the oil flow path, and a bypass flow path which bypasses the valve member. A one-way valve, which permits a supply of a hydraulic pressure from an actuator side to a hydraulic clutch side and which shuts off a supply of a hydraulic pressure from the hydraulic clutch side to the actuator side, is provided on the bypass flow path.

摘要： A method for calibrating a characteristic diagram for a drive-train of a working machine, which contains a brake pedal characteristic of a brake system and a clutch characteristic of a drive clutch, in which an opening point at which the drive clutch is disengaged when a brake pedal of the brake system is actuated as a function of a pedal path, and/or a closing point at which the drive clutch is engaged when the brake pedal is released as a function of the pedal path, is calibrated. When the brake pedal is actuated and/or released an actual rotational speed profile of the drive-train is determined, the actual rotational speed profile determined is compared with a stored corresponding target rotational speed profile, and the opening point and/or closing point of the drive clutch is adapted to minimize deviation of the actual rotational speed profile from the target rotational speed profile.

摘要： A controller causes a clutch to transition from a half-engaged state to an engaged state when a difference in rotational velocity between input and output sides of the clutch falls within a predetermined range in the half-engaged state of the clutch. The controller executes a moving start control to increase an output rotational velocity of a prime mover and cause the clutch to transition to the engaged state when a predetermined first condition is satisfied in the half-engaged state of the clutch.

摘要： An apparatus and methods for testing and pumping through a well servicing system are provided. The apparatus includes a drive mechanism and an actuation system. The actuation system is coupled to the drive mechanism for selectively engaging the drive mechanism to a drive train of the well servicing system's pumping equipment for pressure testing and low rate pumping of the well servicing system without using the primary mover of the pumping equipment. A method for hydrostatic pressure testing of the well servicing system includes putting a transmission of the drive train into neutral and containing the well servicing system, then engaging the drive mechanism to the drive train and activating the drive mechanism to drive the drive train for pumping and compressing test fluid into the well servicing system without using the primary mover. And a method for low rate pumping of an open well servicing system includes putting the transmission of the drive train into neutral, engaging the drive mechanism to the drive train, and activating the drive mechanism to drive the drive train for pumping fluid into the well servicing system at a predetermined flow rate without using the primary mover.

摘要： A clutch control device is provided for a four-wheel drive vehicle for transmitting drive force to the rear wheels. The clutch control device includes a dog clutch and a friction clutch, and a controller that controls the dog clutch and the friction clutch. The controller starts the engagement of the dog clutch, after placing the dog clutch in a rotationally synchronized state by engaging the friction clutch and increasing an output rotation thereof, when there is a request to engage the dog clutch. In this clutch control device, the controller sets the engagement start timing of the friction clutch when a transition is made to the connected, four-wheel drive mode to an earlier timing compared to when a transition is made to the standby two-wheel drive mode, when there is a request to engage the dog clutch while in a state in which the disconnected, two-wheel drive mode is selected.

摘要： When a K0 clutch 34 is interrupted to stop a direct injection engine 12 during vehicle running, if a stop position of a crankshaft 114 is out of a range of a target stop range φtarget, the once interrupted K0 clutch 34 is temporarily frictionally engaged to slightly rotate the crankshaft 114. As a result, the crankshaft 114 stopped near compression TDC (top dead center) is rotated to and stopped in a minimum region of pumping energy in combination with a pumping action. Since the minimum region of the pumping energy overlaps with the target stop range φtarget suitable for ignition start associated with a small assist torque at the time of engine start, the ignition start can properly be performed at the next engine start and the assist torque at the time of engine start can be reduced.
摘要翻译：当K0离合器34中断以在车辆行驶期间停止直接喷射发动机12时，如果曲轴114的停止位置在目标停止范围的目标范围之外，则一旦中断的K0离合器34暂时摩擦接合到稍微旋转曲轴114.结果，在压缩TDC（上止点）附近停止的曲轴114与泵送动作一起旋转并停止在泵送能量的最小区域中。由于泵送能量的最小区域与发动机启动时与小辅助转矩相关联的适合点火开始的目标停止范围φtarget重叠，所以可以在下次发动机起动时适当地执行点火启动，并且在发动机启动时间可以减少。

摘要： A method of regulating a clutch assembly that has a set of clutch plates and a clutch piston with a fluid seal in an automatic transmission that includes a hydraulic circuit is disclosed. The method includes commanding the hydraulic circuit via the controller to apply a first hydraulic force to the clutch piston to displace the clutch piston relative to the set of clutch plates in order to affect a shift between speed-ratios in the transmission. The method also includes determining a drag force of the fluid seal. The method also includes determining a velocity of the displaced clutch piston that results from the drag force of the fluid seal acting counter to the displacement of the clutch piston. The method additionally includes regulating the clutch assembly to compensate for the determined drag force of the fluid seal acting counter to the displacement of the clutch piston.
