  • Patent number: 11167748
    Abstract: A method for exiting from a recuperation phase in a parallel hybrid vehicle includes, in a first step, the vehicle is in a recuperation phase, started by means of a trigger, with a predefined recuperation driving demand, and, in a second step, the electric machine is brought to an increased rotational speed during the recuperation phase. In a third step, a phase for departing from the recuperation phase is started by means of a trigger, wherein, in this phase, the internal combustion engine is made available for coupling to the electric machine, such that a target rotational speed determined between the internal combustion engine to be connected and the electric machine for the connection to the transmission input is set, and in parallel, by means of an upshift, a highest possible gear ratio for the connection to the drivetrain is set, in order to satisfy a present driving demand. In a fourth step, the departure from the recuperation phase is completed.

  • Publication number: 20210339618
    Abstract: A method for implementing an operating strategy for (plug-in) hybrid vehicles. According to the method, it is possible to cause in a particularly advantageous manner an alleviation of the load of a starting device and thereby achieve emission advantages. A correspondingly configured system arrangement is provided for implementing the method. A non-transitory computer-readable medium programmed to execute the method is also provided, in which control commands implement the method and/or operate the proposed system arrangement.

  • Patent number: 11141828
    Abstract: A first actuating element acts on a blocking device for an operator-controlled element for controlling the drive motor. In an enabled position of the blocking device, the operator-controlled element is enabled to control the drive motor. In a blocking position the blocking device mechanically blocks any actuation of the operator-controlled element. The first element acts on the blocking device via a transfer unit. In an actuated position of a second actuating element, the transfer unit establishes an operative connection between the first element and the blocking device, such that the blocking device is in the enabled position in the actuated position of the first element and is in the blocking position in the non-actuated position of the first element. In the non-actuated position of the second actuating element, the transfer unit is ineffective so that the blocking device is in the blocking position regardless of the first element's position.

  • Patent number: 9623547
    Abstract: A handheld work apparatus has a motor unit comprising a drive motor. The drive motor drives a tool of the work apparatus, for example a saw chain. The apparatus has a grip unit with a handle that is vibrationally decoupled from the motor unit via an antivibration element. The antivibration element is connected to a first component of the grip unit via a holding device and a second component of the motor unit via a holding element. Arranged in the connection of the first component to the second component through the antivibration element is a predetermined breaking point formed in a third component that is replaceable independently of the first component and the second component. The strength of the connection of the first component to the second component through the antivibration element is lowest at this predetermined breaking point.

  • Patent number: 9561599
    Abstract: A hand-held work implement comprises a housing, at least one tool and a combustion engine for driving the tool. The combustion engine has a cylinder and has a piston which drives a crankshaft in rotation about an axis of rotation. The crankshaft drives a fan impeller. The work implement has a handle unit with a handle bar and has an engine unit, these being connected to one another via anti-vibration elements. The combustion engine has a transverse plane which encompasses the cylinder longitudinal axis and which runs parallel to the axis of rotation of the crankshaft. The transverse plane divides the work implement into a front region, in which a section of the tool that projects out of the housing is arranged, and a rear region. The fixing of the anti-vibration element to the cylinder is realized in the front region.

  • Patent number: 9464606
    Abstract: A handheld work apparatus has at least one tool which is driven by a combustion engine. A portion of an intake channel of the combustion engine is formed by an elastic connecting piece which has a first section and a second section between which an expansion fold is arranged. The expansion fold has a first side wall and a second side wall arranged downstream of the first side wall. A peripheral wall, which extends in the region of the largest outside diameter (a) of the expansion fold, is arranged in flow direction between the first side wall and the second side wall. The connecting piece has a stop for the expansion fold which prevents a segment of the first side wall adjoining the peripheral wall from bearing against the second side wall.
