  • Patent number: 10406923
    Abstract: A regenerative braking system and method are disclosed. According to certain embodiments, the regenerative braking system is engaged and adjusted when the navigation system recognizes that the vehicle is descending down a long grade. This can be pre-stored information, or information derived from prior experience or from the shared experiences of other drivers. The regenerative braking system does not engage to the full stop of the vehicle, but instead can release at approximately three mph and allows friction braking to handle the rest of the stop. The navigation system in this embodiment recognizes that a stop sign or other full-stop situation is present.

    Abstract: A vehicle and a method for controlling regenerative braking may utilize the maximum available regenerative braking torque for some time during a braking event. As the vehicle speed and/or powertrain torque decreases, the regenerative braking torque is controlled to deviate from the maximum. The point at which the regenerative braking torque deviates from the maximum is chosen based on the level of vehicle deceleration. The regenerative braking torque is then smoothly blended out until it reaches zero. The regenerative braking torque is brought to zero when the vehicle speed is very low, thereby eliminating the inefficiencies associated with operating a motor at a very low speed.

  • Patent number: 7585258
    Abstract: An exercise system includes a user input arrangement; a rotatable member that rotates in response to an input force applied by a user on the user input arrangement; a power sensing arrangement that senses power applied to the rotatable member due to the input force applied by the user; and a variable resistance arrangement interconnected with the power sensing arrangement and with the user input arrangement. The resistance arrangement applies resistance to rotation of the rotatable member, and is variable in response to the power sensing arrangement to vary the resistance applied to the rotatable member. The variable resistance arrangement may be a brake that interacts with the rotatable member to resist rotation of the rotatable member, and to thereby resist the input force applied by the user. The variable resistance arrangement includes a controller for controlling the brake in response to the power sensing arrangement.

    Abstract: Harrison Automobiles (HA) that use the kinetic energy stored in Harrison Flywheel Engines (HFE), and electricity generated by Harrison Flywheel Engines (HE) to power the propulsion and control of automobiles and other machines. Propulsion and control by Harrison Flywheel Engines (HFE) shall also be used for the propulsion of other machines such as trucks, tractors, aircraft, boats, torpedoes, etc. Harrison Flywheel Engines (HFE) are fully flywheel powered, with periodic recharging required by electricity only. No gasoline is required for propulsion, operation or recharging of the Harrison Flywheel Engines (HFE). The typical flywheel powered Engine consists of two or more equal but counter rotating flywheel power units, thus neutralizing the gyroscopic moment caused by each rotating flywheel power unit.

  • Publication number: 20080245625
    Abstract: A brake assembly and system (202) characterized by the use of a flexible force transfer member (230) to enable an electric motor (220) to be mounted remotely from other brake components and preferably at a location shielded from the elements and/or more easily accessible for maintenance and repair. By mounting the electric motor (220) in a less confining area, and using a force distribution device (350) to distribute force to a plurality of rams (342,344), one larger motor (220) may be used to drive multiple disk engagement members rather than several smaller motors mounted on the brake assembly. Since larger motors are typically more efficient than smaller motors, using one larger motor increases the overall efficiency of the brake.

  • Patent number: 7168770
    Abstract: A wind-powered brake system which is operated to brake a movable body when a driving force of a driving source for moving the movable body should be decreased, is described. The object of the present invention is to assist normal braking, to reduce a heat energy loss, and to perform braking suitable for a necessary braking force. A wind tunnel 34 is installed in each armrest 16 of a wheelchair 10. In braking, a load for generating power is put on rotary vanes 40 provided in the wind tunnel 34. Thus, the flow of wind is obstructed, and this functions as a braking force. It is thus possible to brake the wheelchair 10 using a combination of a brake mechanism of an electric motor and a wind-powered brake system. The burden on the brake mechanism of the electric motor can be lessened, and early wear and performance degradation due to frictional heat can be suppressed. By assisting the brake function of the electric motor, the amount of heat energy released from the electric motor into the air can be reduced.

  • Patent number: 6970761
    Abstract: Based on the realization that, at the instant a holding brake in the drive of a machine tool is actuated, it may not be necessary to precisely observe the setpoint values, it may be provided to adapt control parameters in the controller of the drive such that, given an engaged holding brake, oscillations may be avoided or substantially reduced. By applying a correction value to the controller, it may be possible to prevent the adaptation of the control parameters from resulting in a change at the output of the controller.
