A vehicular steering system includes a driving wheel, a wheel drive actuator that rotationally drives the driving wheel, a steering operation mechanism that steers the driving wheel, a steering operation actuator that applies a steering operation force that is used to steer the driving wheel to the steering operation mechanism, and a hydraulic circuit that transmits the rotational driving force of the wheel drive actuator to the steering operation mechanism via hydraulic oil as a steering operation force.

Vehicular steering system

A vehicle includes: a pair of front wheels; a pair of rear wheels; a front-wheel motor configured to drive the front wheels; a rear-wheel motor configured to drive the rear wheels; and a reducer configured to reduce a rotation speed of one of the front-wheel motor and the rear-wheel motor, and transmit drive power to the wheels driven by one of the motors. The one of the front-wheel motor and the rear-wheel motor is a motor with a rotation speed higher and torque lower than those of the other one of the motors.

Vehicle and vehicle driving device

A vehicle drive control device includes a continuously variable transmission mechanism (hereinafter referred to as CVT () of a torque control type capable of continuously varying a transmission gear ratio, and a controller () which controls operations of the CVT () and an engine (). The controller () includes a first control section (A) which controls a torque of the CVT () based on a target transmission input torque (T), and a second control section () which controls a torque of the engine () based on a target engine rotation speed (&#x3c9;).

Drive control device for vehicle

A full-toroidal continuously variable transmission has a hydraulic actuator () for applying pressing force to a pair of disks () through a roller (). The hydraulic actuator () includes first and second oil chambers (). The pressing force of the hydraulic actuator () is produced by a pressure difference between the oil chambers (). A directional control valve (P;Q) connects a hydraulic pressure source (P;Q) to either of the oil chambers, and an oil tank () is connected to the other oil chamber. Each corresponding an intermediate section (Pa,Qa) of a feeding path (P,Q) and intermediate section (Pa;Qa) of a discharge path (P;Q) are connected by a communicational path (P;Q). A check valve (P;Q) for permitting a flow of operation oil only to the feeding path side (P,Q) is provided in the communication path (P;Q). A flow restriction (P;Q) is placed on a downstream side of the intermediate section (Pa;Qa) of the discharge path (P;Q).
