摘要： A temperature warning method of a friction element for issuing a warning depending on temperature of the friction element arranged between a power source and a driving wheel, includes issuing the warning when the temperature of the friction element exceeds an upper limit temperature, and making a period of time, from when the temperature of the friction element exceeds the upper limit temperature until when the warning is issued, longer when the temperature of the friction element exceeds the upper limit temperature for a first time than when the temperature of the friction element exceeds the upper limit temperature for a second or subsequent time.

摘要： A multipurpose vehicle includes an engine, a fuel supply unit that supplies fuel to the engine, a gear transmission device that changes speed of power from the engine through a shifting operation, a coupling state detection sensor that detects a coupling state of the gear transmission device, a determination unit that determines whether the coupling state is an incomplete coupling state based on a detection signal from the coupling state detection sensor, and a fuel supply control unit that executes a fuel cut to reduce a fuel supply amount of the fuel from the fuel supply unit to the engine to a value less than a reference value, if the determination unit determines that the coupling state is the incomplete coupling state.

摘要： A method of operating a transmission includes measuring an output torque, estimating a gearbox input torque using a model, and estimating gearbox component torques based on a detailed gearbox model. The model used to estimate the input torque varies depending on whether a torque converter is locked, open, or slipping. In some operating conditions, multiple estimates are available for gearbox input torque, impeller torque, or shift element torque in which case the models are adapted. When an estimated component torque is outside an expected range, a warning flag is raised and diagnostic data is saved. When an estimated torque approaches or exceeds a torque limit, the input torque command may be reduced to prevent component damage. A warning flag may also be raised and diagnostic data saved in response to a model parameter being adapted to a value outside of a predetermined range.

摘要： A control method for an automatic transmission and a two-way clutch includes determining whether a current speed stage is a forward speed stage, comparing a rotation speed of the two-way clutch with a predetermined minimum rotation speed if a current speed stage is a forward speed stage, deciding that the two-way clutch has failed when a rotation speed of the two-way clutch is lower than the predetermined minimum rotation speed, and performing a fail-safe mode if the two-way clutch has failed.

摘要： A method of managing slip in a transmission that is driven by a prime mover includes determining whether a slip condition of the transmission is present based on a slip value and reducing a torque output of the prime mover based on a torque reduction value when the slip condition is present. The method further includes storing the torque reduction value in an array if the slip condition is resolved as a result of the step of reducing and identifying a faulty component within the transmission based on the array.

摘要： In a planetary gear type stepped automatic transmission, a gear shift control to shift a gear shift stage between a first gear shift stage and a second gear shift stage is performed by a first shift control section by referring to a first gear shift control data used when the gear shift stage is switched between the first gear shift stage and the second gear shift stage, an abnormality state due to a failure of at least one of a first frictional engaging element and a second frictional engaging element is detected, and an abnormality state gear shift control is performed to shift the gear shift stage between a third gear shift stage (for example, first speed) and a fourth gear shift stage (for example, 2.5 speed) by the first shift control section, while forcefully releasing the first frictional engaging element, when detecting the abnormality state.

摘要： There is provided a fail control apparatus for an automatic transmission, which, in the event of a friction element failure, is capable of coping with the failure by identifying a failed part without erroneous determination and within a short time. The set gear ratio of a designated gear position at the time of failure and the actual gear ratio are compared with each other to determine whether a friction element has failed, and an alternative gear position which enables a vehicle to start moving again is designated based on the determination result. In determining a failed friction element, one friction element disengaged or engaged due to failure is identified only when the designated gear position is the first speed gear position which is achieved by engaging one low clutch and a one-way clutch. It is therefore possible to determine the details of failure with accuracy and properly set an alternative gear position. On the other hand, when the designated gear position at the time of failure is other than the first speed gear position, in which a plurality of friction elements are engaged, one friction element which has failed is not identified, and it is therefore possible to quickly set an alternative gear position without the possibility of erroneous determination.
摘要翻译： 提供了一种用于自动变速器的故障控制装置，在摩擦元件故障的情况下，能够在短时间内通过识别故障部件而不会错误地确定故障。 将故障时的指定档位的设定齿轮比和实际齿轮比进行比较，以确定摩擦元件是否已经失效，并且基于以下方式指定使车辆再次起动的替代档位 确定结果。 在确定失效的摩擦元件时，仅当指定的档位是通过接合一个低离合器和单向离合器而实现的第一速度档位时才识别出由于故障而脱离或接合的一个摩擦元件。 因此，可以精确地确定故障的细节，并适当地设置替代档位。 另一方面，当故障时的指定档位不同于多个摩擦元件接合的第一速度档位时，未识别出有故障的一个摩擦元件，因此可以 快速设置替代档位，而不会有错误的确定。
