Abstract: A continuously variable transmission having a variator (5) comprising input discs (2) coupled to an input shaft (12) and an output disc (3) providing a rotary variator output. The input and output discs are mounted for rotation about a common axis and at last one roller (4) is arranged between the discs to transfer drive from one to the other at a continuously variable variator drive ratio. The roller is mounted in a carrier (30) in a manner which permits it to spin about its own axis and to tilt relative to the disks to vary the variator drive ratio. A hydraulic actuator (22) is arranged to apply to the carrier (30) a reaction force determined by a hydraulic pressure difference acting on the actuator. The reaction force opposes a traction force applied to the roller (4) by the action of the discs (2, 3).

Abstract: A vehicle control device which can provide compatibility between a high grip performance and fuel efficiency is provided. When a camber angle of a wheel 2 is adjusted to a negative camber, ground contact pressure in a first tread 21 is increased and ground contact pressure in a second tread 22 is decreased. Accordingly, the high grip performance is provided. On the other hand, when the camber angle of the wheel 2 is adjusted to a positive camber, the ground contact pressure in the first tread 21 is decreased and the ground contact pressure in the second tread 22 is increased. Accordingly, a rolling resistance becomes low, and fuel saving is achieved. In this manner, by adjusting the camber angle of the wheel 2, the compatibility can be provided between conflicting performances of the high grip performance and the fuel saving.

Abstract: A driver model with higher precision is created as an evaluation standard for a driving condition in a normal condition. By detecting biometric information of a driver, whether a driver is in a usual condition or not is recognized. Then, data of driving conditions are collected while the driver is driving, and from the driving condition data, a part indicating that the driver operates in a usual condition is extracted to create a driver model. Further, the driver model is created taking only a case of driving in a normal condition as a driving action in normal times based on biometric information of the driver, and hence the driver model becomes more precise and neutral. Further, by using a GMM (Gaussian mixture model) for the driver model, a driver model for each driver can be created easily, and moreover, by calculation to maximize a conditional probability, a driving operation action is easily estimated and outputted.

Abstract: When measurements by sensors are impossible, the angular position of the vehicle is estimated from the conditions including rotation of the drive wheel and the driving torque so that the vehicle may travel in an inverted-pendulum position even in case of a failure of measurements of the vehicular position of angle. To achieve the object, the vehicle has a drive wheel rotatably mounted beneath a vehicular body, and a control unit that controls the vehicular position of angle through control of drive torque imparted to the drive wheel. The control unit has a means to estimate the vehicular angular position with respect to a vertical position from the conditions of rotation of the drive wheel and the driving torque.

Abstract: Disclosed is a vehicle which makes it possible to control the vehicle traveling state and the vehicle attitude with a high degree of precision, even when the vehicle is traveling quickly, and affords safe and pleasant travel for a range of traveling conditions, by the appropriate correction of the drive torque of a drive wheel in response to the traveling velocity of the vehicle and the position of the center of gravity of the vehicle body. For this purpose, the vehicle comprises a drive wheel rotatably mounted on the vehicle body, and a vehicle control device for controlling the drive torque imparted to the drive wheel to control the attitude of the vehicle. The vehicle control device causes the center of gravity of the vehicle body to move relative to the drive wheel by an amount corresponding to the rotational angular velocity of the drive wheel in the direction of travel of the drive wheel.

Abstract: A vehicle has a drive wheel, a seat, an attitude sensor, a balancer movable relative to the seat, a drive control, an attitude control for controlling the attitude of the seat by moving the balancer and a main controller. The main controller calculates a torque T1 for tilting the seat and a torque T2 for moving the balancer forward, compares T1 with T2max (the maximum torque which can be generated by the balancer), and outputs commands to the drive control and the attitude control. When the calculated torque T1 exceeds T2max, responsive to a command for T2max, the attitude control moves the balancer to generate a reaction torque corresponding to T2max, and the main controller supplies an adjustment torque value T3 for the drive wheel. The drive control controls the drive wheel in accordance with the drive command and the adjustment torque value T3.

Abstract: A vehicle control device and a vehicle are provided with compatibility between high grip performance and fuel efficiency. When a camber angle of a wheel is adjusted as a negative camber, the ground contact pressure on a first tread is increased and the ground contact pressure on a second tread is decreased, thus providing the high grip performance. On the other hand, when the camber angle of the wheel is adjusted as a positive camber, the ground contact pressure on the first tread is decreased and the ground contact pressure on the second tread is increased, thereby reducing rolling resistance and achieving fuel saving. By adjusting the camber angle of the wheel, compatibility can be provided between high grip performance and fuel saving which otherwise conflict with each other.

Abstract: The gradient of a road surface is estimated with a change in the attitude of a vehicle also taken into consideration. As a result, the gradient of the road surface can be estimated with high accuracy, and this enables the vehicle to stably stop and travel independently of the gradient of the road surface. The vehicle has a drive wheel rotatably mounted on a vehicle body and also has a vehicle control device for controlling the attitude of the vehicle by controlling drive torque applied to the drive wheel. The vehicle control device estimates the gradient of the road surface based on the attitude of the vehicle and corrects the drive torque based on the gradient.

Abstract: A vehicle capable of stably turning by improving turning performance and that is able to ensure comfort by reducing a burden on a driver is provided. A link mechanism is bent and stretched to incline both left and right wheels to the inside during a turn to generate camber thrust by side force and, as a result, turning force is increased. Further, when the link mechanism is bent and stretched, a coupling link is inclined and a passenger section is inclined, thus making it possible to move the center of gravity of the vehicle toward an inner wheel during a turn. By so doing, lift of the inner wheel during a turn is prevented to make it possible to improve turning performance. In addition, since the passenger section is inclined to the inner wheel side during a turn, it is possible to make a passenger experience less centrifugal force.

Abstract: When a vehicle climbs up/down a step, driving torque suitable for the step climbing operation is applied to a driving wheel, and the center of gravity of a vehicle body is moved in an upward direction of the step. Thus, a stable traveling state and stable posture of the vehicle body can be maintained both when climbing up a step and when climbing down a step, whereby an occupant can operate the vehicle safely and comfortably even on a place having steps. In view of this, the vehicle includes: a vehicle body; a driving wheel rotatably attached to the vehicle body; and a vehicle control apparatus for controlling driving torque that is applied to the driving wheel and controlling posture of the vehicle body. When climbing up/down a step on a road, the vehicle control apparatus controls a position of center of gravity of the vehicle body in accordance with the step.

Abstract: A camber angle applying device is controlled to adjust the camber angle of wheels to a predetermined value. Therefore, the characteristics (or a high gripping property) of a high gripping force and the characteristic (or a low rolling resistance) of a small rolling resistance can be separately used as the performance of the wheels. By utilizing the high gripping property of the wheels, therefore, a vehicle is enabled to reduce its energy consumption, while retaining its running characteristics (such as a turning performance, an accelerating performance or a braking performance), by utilizing the rolling resistance of the wheels. Moreover, the camber angle applying device is controlled to reduce the rolling resistance of the wheels, so that the energy loss to occur in the wheels during running can be reduced to further reduce the energy consumption of the vehicle.

Abstract: A control device corrects the alignment of wheels of a vehicle during travel to improve fuel consumption performance. Operating conditions of a suspension device (alignment adjustment device) are controlled by alignment control while the vehicle is traveling, and when the alignment of the wheels is adjusted, travel resistance of the vehicle increases or decreases. The control device detects the travel resistance of the vehicle based on the value of an electric current supplied to a wheel drive device (electric motor), and the alignment of the wheels is adjusted so that the travel resistance of the vehicle decreases. As a result, the alignment of the wheels during travel is adjusted to a correct state to improve fuel consumption performance.

Abstract: An inverted vehicle in which the angle of tilt of a vehicle body due to acceleration can be reduced by ground engagement members. The vehicle causes assist wheels to engage the ground when acceleration of the vehicle exceeds a predetermined threshold value to accelerate/decelerate the vehicle. The acceleration may be either requested acceleration or actual acceleration. The ground contact points of the assist wheels are set so that higher the acceleration, the farther away the ground contact points are from the ground contact points of the drive wheels, in the direction opposite to the direction of the acceleration. When the acceleration is within a predetermined range, the vehicle body tilts to a corresponding angle, and when the acceleration exceeds the predetermined threshold value, the assist wheels engage the ground to prevent the vehicle body from tilting beyond a predetermined value.

Abstract: A vehicle provides upstanding and tilted (standstill for allowing a user to get on an off the vehicle) positions without movement of the vehicle. In the vehicle, even if the vehicle body tilts, a riding section is moved in the forward-backward direction to bring the vehicle to an orientation where the center of gravity (P) of the vehicle body is on a vertical line (V) passing through ground contact points (S1) or drive wheels (12). This controls the tilt angle of the vehicle body and the position of the riding section (13) so that the center of gravity (P) does not move. Thus, the upright position and the tilted position of the vehicle are achieved without movement of the vehicle (without rotation of the wheels). Further, influences such as an error in parameters and disturbance are compensated for by a balancer that moves in the forward-backward direction.
