| 20120046856 | VEHICLE - 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. | 02-23-2012 |
| 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 |

| 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 |

| 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 |

The vehicle control device is characterized by including: a communication unit that receives running condition data from the preceding vehicle regarding a vehicle speed and a joystick operation amount of the preceding vehicle; an inter-vehicle distance sensor that measures an inter-vehicle distance with the preceding vehicle; and a main control ECU that computes an acceleration command value for following the preceding vehicle, wherein the main control ECU sets one of a first acceleration command value, which is computed based on the vehicle speed of the preceding vehicle acquired through the communication unit and the inter-vehicle distance measured by the inter-vehicle distance sensor, and a second acceleration command value, which is computed based on the joystick operation amount acquired through the communication unit, as a target acceleration command value. | 11-25-2010 |
| 20100217491 | CAMBER ANGLE CONTROLLING DEVICE - 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. | 08-26-2010 |
| 20100198441 | CONTROL APPARATUS - 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. | 08-05-2010 |
| 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 |
| 20100114420 | VEHICLE - 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 (S | 05-06-2010 |
