摘要： PROBLEM TO BE SOLVED: To provide a control device of a belt continuously variable transmission for vehicles capable of suppressing the relative rotation of movable rotating bodies when a vehicle is changed over between a drive state and a driven state. SOLUTION: This control device of a belt continuously variable transmission for vehicles comprises a changeover transient holding pressure control means 128 for temporarily increasing a holding pressure from a movable rotating body 46b applied onto a transmission belt 48 when the drive state and the driven state of the vehicle are judged to be changed over from one to the other. In the changeover period between the drive state and the driven state of the vehicle, a pressing force from the movable rotating body 46b to a fixed rotating body 46a through the transmission belt 48 is temporarily increased. Therefore, when the movable rotating body 46b is rotated by a predetermined rattling angle A amount relative to the fixed rotating body 46a, the rotation is suppressed due to an increase in a frictional force due to the rise of the pressing force, namely, an increase in the braking force, and a large impact load is suppressed from generating in a guide mechanism 46g, to suppress both the lowering of the durability and operability of the control device.

摘要： PROBLEM TO BE SOLVED: To provide an alarm device for vehicles which can perform dramatic effects for safely enjoying driving, while issuing alarm against the sideslip of a vehicle.
SOLUTION: Whether a vehicle speed V is a prescribed speed Va or higher is determined (Step S110), and whether a steering angle θ is a prescribed angle θa or larger is determined (Step S120). When the vehicle speed V is the prescribed speed Va or higher and the steering angle θ is the prescribed angle θa or larger, the threshold is changed to a small value (Step S130). When the threshold is changed to a small value, since the pseudo-squeals of tires tend to occur, a driver can enjoy sporty dramatic effect.

摘要： PROBLEM TO BE SOLVED: To provide a controller for a vehicle with a continuously variable transmission, allowing acquisition of a sufficient acceleration feeling to acceleration operation of a driver. SOLUTION: When acceleration requirement is decided by an accelerator operation decision means 86, a control means 90 sets a target drive force POWER higher than a normal target drive force calculated in normal operation of an accelerator pedal 71, sets an accelerating target rotational speed NINLINE higher than a normal rotational speed calculated in the normal operation, increasing at a prescribed gradient β to increase of a vehicle speed, and controls output torque of an engine 12 and a change gear ratio γ of the continuously variable transmission 18 such that the set target drive force POWER is accomplished and that an input shaft rotational speed N IN of the continuously variable transmission 18 becomes the set accelerating target rotational speed NINLINE. Accordingly, when the acceleration requirement is performed by the driver, the target drive force can be increased, and the output rotational speed of a power source can be increased, so that the sufficiently high acceleration feeling can be obtained from the vehicle to a requirement output amount.

摘要： PROBLEM TO BE SOLVED: To provide a quality testing method capable of easily and correctly performing total inspection on durability of an endless metal belt.
SOLUTION: In this method, the endless metal belt is kept wound around a sheave to measure height of a specified periphery side area from a saddle face through which each metal belt element in the part wound around the sheave passes, while previously determining the relation between height of the saddle face and the height of the specified area at the part wound around the sheave. Thus accuracy in the height of saddle face is examined based on both the predetermined relation and measurement value of the specified area height to determine whether the quality the endless metal belt(steps 3-6) is good or bad.

摘要： PROBLEM TO BE SOLVED: To suppress the slippage between the belt of a belt type continuously variable transmission and a pulley after a friction engagement device is engaged in starting a vehicle.
SOLUTION: In starting the vehicle, oil is supplied from a first route 36 to a forward clutch 16 or a reverse brake 17. By drivingly controlling a garage shift control valve 39 in the first route 36, hydraulic pressure acting on the forward clutch 16 or the reverse brake 17 is controlled so that the forward clutch 16 or the reverse brake 17 can be smoothly engaged. After the forward clutch 16 or the reverse brake 17 is engaged, oil supply through the first route 36 is continued until a specified time t is passed. Thus, oil is supplied through the first route 36 to those portions of the forward clutch 16 or the reverse brake 17 where oil is not filled. When the specified time t is passed, oil is supplied to the forward clutch 16 or the reverse brake 17 through a second route 37 by changing over a garage shift valve.

摘要： PROBLEM TO BE SOLVED: To restrain slip between a pulley and a belt of a belt type continuously variable transmission when switching between advancing and retreating of a vehicle. SOLUTION: In a process for reversing input rotation of the belt type continuously variable transmission 4 in order to switch advancing and retreating of an automobile, a carrier 15 is reversely rotated after the rotating speed of the carrier 15 in an advance and retreat switch device 3 is lowered to 0. In order to achieve reduction of the rotating speed of the carrier 15, an advancing clutch 16 and a retreating brake 17 are engaged or released. The engine rotating speed is lowered by friction resistance at that time, and an oil delivery pressure of an oil pump 11 for adjusting a belt fastening pressure of the belt type continuously variable transmission 4 is lowered. The lowering of the oil delivery pressure is restrained by increasing the engine rotating speed by raising the engine output before the advancing direction of the automobile is actually switched after advance and retreat switch instruction is made.

摘要： PROBLEM TO BE SOLVED: To improve the comfortableness by suppressing the shock in chip-in acceleration regardless of a knocking measure and to improve the deterioration of fuel consumption or traveling performance while suppressing the generation of muffled sound. SOLUTION: When the delay control of ignition timing of an engine 12 is performed by a knocking counter measure means 104 when an accelerator operation is performed from idling traveling in the engagement of a lock-up clutch 26, an annealing treatment is not properly performed by an annealing treatment means 106. Therefore, the lock-up clutch 26 is released to prevent the shock. When the engine speed is raised by the accelerator operation, in the engagement of the lock-up clutch 26, and gets in a muffle sound generating area, the lock-up clutch 26 is released, a continuously variable transmission 18 is changed in speed so that the turbine rotating speed gets out of the muffled sound generating area, and the lock-up clutch 26 is then re-engaged to extend the engagement area of the lock-up clutch 26.
