A vehicle control device mounted on a vehicle includes a first traveling mode being driven by the torque output from a first rotary electric machine, and a second traveling mode being driven by the engine torque output from an engine and the torque output from the first rotary electric machine, wherein a section 1 for cranking the engine by the output of the second rotary electric machine and a section 2 for assisting the driving force of the engine by the output of the first rotary electric machine are provided during a period from the first traveling mode to the engagement of the clutch at the time of starting the engine to the second traveling mode, and the torque increase of the first rotary electric machine is limited in the section 1.

Vehicle control device

Elements of a transmission belt wound around pulleys of a continuously variable transmission each include a body part, a pair of pillar parts, and a pair of side surfaces. The pair of side surfaces each include a first side surface formed on a corresponding one of the pillar parts; and a second side surface formed so as to continue from the first side surface, and located more on an inner circumference side than the first side surface. A pair of the first side surfaces each are formed so as to be inclined toward an inner side of a corresponding one of the pillar parts with respect to an extending direction, from an inner circumference side to an outer circumference side of a ring, of a corresponding one of the second side surfaces continuing from the first side surface, and a pair of the second side surfaces is formed such that the second side surfaces are spaced farther apart from each other as the second side surfaces extend from the inner circumference side to the outer circumference side, and that an angle formed between the pair of the second side surfaces is larger by 0.2 to 0.8 degrees than an opening angle of V-shaped grooves of the pulleys.

Transmission belt and continuously variable transmission, method for designing element, and method for producing element

In an element of a power transfer belt to be wound around a primary pulley and a secondary pulley of a continuously variable transmission to transfer torque, the distance from a boundary line between a surface positioned on the outer peripheral side of the power transfer belt with respect to a rocking edge portion and the rocking edge portion to a saddle surface is determined from the slip amount due to micro slip which is relative slipping between the element and the primary pulley caused when the primary pulley pushes out the power transfer belt toward the secondary pulley, and the angular speed of the element and the angular speed of a ring in a range in which the power transfer belt is wound around the secondary pulley.

A continuously variable transmission is configured such that a transmission ratio continuously changes by continuously changing widths of belt winding grooves of a primary pulley and a secondary pulley, and includes: the primary pulley including a first fixed sheave and a first moving sheave provided in a primary shaft; the secondary pulley including a second fixed sheave and a second moving sheave provided in a secondary shaft; a metal transmission belt wound around the primary pulley and the secondary pulley; and a moving apparatus configured to integrally move the secondary shaft and a secondary bearing supporting the secondary shaft such that a relative positional relationship between the first fixed sheave and the second fixed sheave changes.
