摘要： The present disclosure presents a wheel diameter variation-detecting device capable of properly detecting relative variation in diameter between a plurality of wheels of a vehicle. The wheel diameter variation-detecting device can detect variation in diameter between a plurality of wheels of a vehicle, can detect rotational speeds of the respective wheels, and can calculate a variation parameter indicative of variation in diameter between the wheels using one of the wheels as a reference wheel, based on a result of comparison between the rotational speed of the reference wheel and that of one of the wheels other than the reference wheel. Further, the wheel diameter variation-detecting device can learn the variation parameter based on a value obtained by averaging a plurality of values of the variation parameter obtained before the detected travelled distance reaches a predetermined distance.

摘要： A demand driving force parameter indicative of a demand driving force of the engine is set based on the accelerator pedal operation amount, and a target value of an engine driving force control amount is set based on the demand driving force parameter. The engine driving force control amount is controlled so as to coincide with the target value. A target rotational speed of the engine is set based on the demand driving force parameter, and the continuously variable transmission is controlled so that the rotational speed of the engine coincides with the target rotational speed. One of a first operation mode and a second operation mode is selectable, wherein the fuel consumption rate in the second operation mode is less than the fuel consumption rate in the first operation mode. When the second operation mode is selected, the demand driving force parameter corresponding to the accelerator pedal operation amount is set to a value which is smaller than a value of the demand driving force parameter in the first operation mode, and the target value is calculated based on a first predetermined characteristic preliminarily set according to the engine rotational speed and the demand driving force parameter. The first predetermined characteristic is set so that the target value corresponding to the same engine rotational speed is substantially constant in a first predetermined range of the demand driving force parameter.

摘要： A vehicular transmission comprises an engine E, a continuously variable transmission CVT and a starting clutch 5. The driving force from the engine E is conveyed through the continuously variable transmission CVT with a speed change to a countershaft 2, and the starting clutch 5 is used to convey this driving force from the countershaft 2 to wheels of a vehicle. The continuously variable transmission CVT is hydraulically controlled by a control valve CV which receives control signals through a line 35 from an electrical control unit ECU. When the temperature of the oil used for engaging and disengaging the starting clutch 5 is equal to or higher than a predetermined temperature, the transmission allows the engine E to stop operating. This control to terminate the operation of the engine is an idling elimination control and is achieved by terminating the fuel supply to the engine and by maintaining the resulting condition of non-fuel supply while the vehicle is being decelerated and brought into a halt.
