  • Patent number: 9552682
    Abstract: A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices. To charge, the machines employ electrical current from an external source. As demand at individual collection, charging and distribution machines increases or decreases relative to other collection, charging and distribution machines, a distribution management system initiates redistribution of portable electrical energy storage devices from one collection, charging and distribution machine to another collection, charging and distribution machine in an expeditious manner. Also, redeemable incentives are offered to users to return or exchange their portable electrical energy storage devices at selected collection, charging and distribution machines within the network to effect the redistribution.

    Abstract: A self-right apparatus is a device for automatically returning an overturned vehicle to an upright orientation. The device features a base plate that is mountable to a vehicle and a flip plate that is hingedly connected to the base plate via a pivot axle. The flip plate is held in place by a trigger mechanism engaged to a catch until the device is ready to be deployed to flip the overturned vehicle. The device utilizes a clutched servo mechanism that is connected to the trigger mechanism. The clutched servo mechanism is actuated in order to release the trigger mechanism from the catch and allow the flip plate to rotate about the pivot axle via force provided by a plurality of torsion springs. The flip plate is pressed against the surface on which the vehicle has become overturned, causing the vehicle to flip and return to its original upright orientation.

    Abstract: A lean-compensating motorcycle for balancing a user includes a lower frame with wide wheels and an upper frame supporting a rider. The lower and upper frames pivot on an axis substantially parallel to the motorcycle's line of travel, and a pivot drive governs pivoting movement. The pivot drive is controlled by a level-sensing control system that adjusts the pivot drive to maintain the upper frame upright by applying force against the lower frame, the lower frame counterbalancing the pivoting motion against the wide wheels. The wheels ideally include a central channel sized to accommodate raised pavement markers, such as dots and reflectors, to provide for smooth travel. The upper frame includes a housing in which the user sits, in a manner similar to a conventional automobile since propping the motorcycle up with the user's legs is largely unnecessary.

  • Patent number: 8498773
    Abstract: A stability enhancing system for a vehicle having a suspension system including a spring is disclosed herein. The stability enhancing system includes, but is not limited to, a processor that is mounted on the vehicle. A sensor is mounted on the vehicle and is communicatively coupled to the processor. The sensor is configured to detect a dynamic condition of the vehicle. A locking mechanism is connected to the spring and is communicatively coupled to the processor. The locking mechanism is configured to inhibit the spring from releasing a stored energy when the locking mechanism is locked. The processor is configured to obtain the dynamic condition from the sensor, to utilize the dynamic condition to determine whether a wheel lift event will occur, and to provide commands to the locking mechanism to lock if the processor determines that a wheel lift event will occur.

  • Patent number: 8423274
    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.

  • Patent number: 8408351
    Abstract: A vehicle includes a suspension system operatively connecting a vehicle body to a plurality of wheels for maintaining contact between the wheels and a road surface, and for maintaining handling of the vehicle. A system for steering the vehicle and a braking system for decelerating the vehicle are also included. The vehicle additionally includes a plurality of thrusters, wherein at least one of the thrusters is arranged relative to each wheel and each of the plurality of thrusters is configured to generate a force. Furthermore, the vehicle additionally includes a controller configured for regulating the force generated by each of the thrusters to assist the suspension system with maintaining contact between the wheels and the road surface and maintaining handling, assist the steering system with steering, and assist the braking system with decelerating the vehicle. A method of assisting the vehicle suspension, steering, and braking systems is also disclosed.

  • Patent number: 8408598
    Abstract: An anti-tip system is provided for improving the stability of a powered vehicle, such as a powered wheelchair. The vehicle includes a drive-train assembly pivotally mounted to a main structural frame. A suspension system biases the drive-train assembly and its connected anti-tip wheel to a predetermined resting position. The drive-train assembly bi-directionally rotates about a pivot in response to torque applied to or acceleration forces on the vehicle. A linkage arrangement is provided and is characterized by a suspension arm pivotally mounting to the main structural frame about a pivot at one end thereof and an anti-tip wheel at the other end. The linkage may further include at least one link operable to transfer the bi-directional displacement of the drive-train assembly to the suspension arm. The link may include a bell crank member and/or may be resiliently compressible.

  • Patent number: 8352122
    Abstract: An engine control apparatus that effectively suppresses a rise in rotation number of an engine in a jump of a vehicle. An engine control apparatus includes an acceleration detecting device for detecting an acceleration component of gravity acceleration in a perpendicular direction of the vehicle body based on a signal inputted from an acceleration sensor, and a control circuit for judging whether the vehicle has jumped or not based on the acceleration component to be detected. The control circuit suppresses a rise in rotation number of the engine when the vehicle is judged to have jumped.

  • Patent number: 8315765
    Abstract: In a method for reducing the rollover risk in vehicles, at least one state variable which characterizes the transverse dynamics of the vehicle is ascertained and is used as the basis for an intervention into the steering system and the braking system which stabilizes the vehicle. A multivariable control is carried out in which two control loops are superimposed, the first control loop being based on control of the yaw rate and the second control loop being based on control of the transverse acceleration. The steering system as well as the braking system may be adjusted via the first and second control loops.

  • Patent number: 8292326
    Abstract: A stabilizer is disclosed for a three-wheel vehicle having a frame extending between a front portion and a rear portion. The front portion of the frame supports a front steering wheel and with the rear portion of the frame supports plural driving wheels. The stabilizer comprises a right and a left stabilizing wheel mounted on a right and a left side of the frame. The right and left stabilizing wheels are positioned above the supporting surface when the three-wheel vehicle moves in a straight direction on a supporting surface. The right and left stabilizing wheels engage the supporting surface when the vehicle is turned in a right and a left direction respectively for stabilizing the three-wheel vehicle while maintaining steering ability. Preferably, the stabilizer includes a right and a left director for directing the right and left stabilizing wheels in a forward direction when the right and left stabilizing wheels are positioned above the supporting surface.
