20090256331 | Vehicle - By bending and stretching a link mechanism, both left and right wheels of a vehicle can be inclined toward inside of cornering to generate a camber thrust as a lateral force, i.e. an increase in cornering force. Further, by bending and stretching the link mechanism, the passenger compartment can be inclined in accordance with inclination of a connecting link, and thus the center of gravity of the vehicle can be moved toward its inner wheel during cornering. By preventing lifting of the inner wheel during cornering, cornering performance is improved. Because the passenger compartment is inclined toward the inner wheel during cornering, centrifugal force is less likely to be felt by the occupant. | 10-15-2009 |

20100017090 | VEHICLE - During vehicle operation, drive wheels are constantly monitored to see whether or not slip of drive wheels occurs and when slip is detected, posture control for slip conditions is performed by uncoupling normal posture control for the drive wheels. A balancer (weight body) which is movable in a longitudinal direction of the vehicle is provided, and posture control is performed by moving the balancer backward when the vehicle inclines forward due to slip and moving the balancer forward when the vehicle inclines backward. The detection of slip is through a comparison between the drive wheels circumferential speed V | 01-21-2010 |

20100070132 | VEHICLE, CHARACTERISTIC VALUE ESTIMATING DEVICE, AND LOADED ARTICLE DETERMINATION DEVICE - A vehicle whose attitude can be controlled even if the position of the actual center of gravity of the vehicle is not aligned with the position of the designed center of gravity or moved. The effect of the displacement of the actual center of gravity of the vehicle from the designed center of gravity is detected as the torque value produced by the displacement of the center of gravity of the vehicle as shown in FIGS. | 03-18-2010 |
20100071984 | VEHICLE - A transverse two-wheeled vehicle has an increased turning limit value. A turning limit estimation system obtains a turning limit value and a center-of-gravity position adjustment system improves the obtained turning limit value. The turning limit estimation system obtains values for turning limit and turning stability by estimating a center-of-gravity position and a lateral acceleration. In the center-of-gravity position adjustment system, the turning limit value is increased by causing the estimated center-of-gravity position to move toward a centripetal direction. The mechanism for moving the center of gravity to is one or more of i) a vehicle body tilt mechanism, ii) a weight movement mechanism, and iii) a seat parallel movement mechanism. Accordingly, particularly a vehicle with two wheels narrowly spaced and a high center of gravity, can make a faster and smaller turn, and driving performance, stability, and security of the turning operation are improved. | 03-25-2010 |
20100114421 | VEHICLE - 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. | 05-06-2010 |

20100305840 | VEHICLE - 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. | 12-02-2010 |
20110098884 | VEHICLE - 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. | 04-28-2011 |
20110264350 | VEHICLE - 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. | 10-27-2011 |
20120123647 | VEHICLE - A vehicle provides a greater maximum acceleration/deceleration, while maintaining a pleasant driving, when M is a total vehicle mass, L is a height of center of gravity of the whole vehicle, λ is a maximum displacement amount of a balancer, and m is a mass of the balancer, the balancer mass m or the maximum displacement amount λ, of the balancer is decided so as to satisfy the following expression: (m/M)(λ/L)=α. By using the expression 1, the balancer mass m and the maximum displacement amount A, of the balancer can be set to an optimal value against the total vehicle mass M. Thus it is possible to decide the balancer mass m and the maximum displacement amount λ for the maximum acceleration α of the vehicle. | 05-17-2012 |
