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: 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.

On the other hand, when the camber angle of the wheel 2 is adjusted to a positive camber, the ground contact in the first tread 21 is decreased and the ground contact 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 or the quietness and the fuel saving.

Abstract: 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.

Abstract: To provide a vehicle which can move independently as an own independent vehicle and can run integrally in linkage with another vehicle. A plurality of single-seat vehicles which can move independently are combined and they move integrally while a predetermined formation is maintained through linkage among respective vehicles. One of all the vehicles moving in linkage serves as a host vehicle and an occupant in the host vehicle becomes a driver in the linkage moving. A host vehicle 1 runs with speed/direction according to running operation conducted by an occupant. Simultaneously therewith, the host vehicle 1 instructs following vehicles 2 to 4 to synchronize (follow) the host vehicle. The host vehicle 1 transmits a speed, a direction, and a relative position to the host vehicle to the following vehicles 2 to 4 as moving information in order to synchronize the following vehicles with the host vehicle (maintain linkage relationship).

Abstract: A separator of a fuel cell, which is inserted between single cells, each single cell having an electrolyte sandwiched between electrodes, in order to stack the single cells together, includes gas diffusion portions which are arranged so as to cover a surface of the electrodes and in which are formed multiple air holes for gas diffusion, and spacer portions which form parallel divided gas passages on the back side of portions of the gas diffusion portions which cover the surface of the electrodes. The gas diffusion portions and the spacer portions are integrally formed by bending a wire mesh member to have a rectangular corrugated plate shaped cross-section. As a result, the air holes are formed evenly between the electrodes and the separator and high contact pressure is ensured by the contact of the fine wire mesh, thereby making it possible to both have the gas diffuse evenly and reduce the power collection resistance.

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 present invention provides a novel method for generating braking force in a wheel. In a vehicle having wheels, a wheel control device for controlling the wheels is provided with an actuator for performing an operation to vary a slip angle of the wheels, and a controller for controlling the actuator to increase the braking force of the wheels by increasing the slip angle absolute value of the wheels such that a lateral force is generated in the wheels relative to a ground contact surface of the wheels.

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: A fuel cell includes a separator (10B) interposed between adjacent unit cells (10A). A mixed fluid of air and water is supplied to an air electrode (12) of each unit cell. The separator includes a mesh conductor (14) on at least a surface facing the air electrode of the unit cells, and the mixed fluid passes through the mesh conductor. Water is retained on the mesh portion of the conductor. With this configuration, it is possible for the unit cell to be cooled by the release of latent heat when the water is evaporated by the heat of unit cell, without any clogging which inhibits contact between the electrode and the air.

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.
