An actuator for an electric parking brake, EPB, is described. The actuator comprises a motor configured to actuate an actuating member of the EPB, as well as a reception interface configured to receive an enablement code. An enablement code is assigned to the EPB actuator which individualizes the EPB actuator against other EPB actuators. The actuator further comprises an evaluation unit configured to verify the received enablement code on the basis of the enablement code allocated to the EPB actuator and to enable a control of the motor in case of a positively verified enablement code. There is further provided a control device for the EPB actuator, an electric parking brake and a vehicle having the EPB actuator and corresponding operating methods.

A parking lock-releasing device for a vehicle, which is capable of improving workability in manually releasing a parking lock while ensuring sealing performance of an outer casing, and easily holding the locking released state. The locking release operation section includes a base having a hollow cylindrical guide portion and concentrically continuous with a front end of the outer casing, with a female screw formed on an inner peripheral surface thereof, and an operating section body which is screwed via a male screw formed on an outer peripheral surface thereof into the female screw of the guide portion, closes the guide portion, holds a front end of the inner cable, and when releasing the locking, is rotatingly operated in a predetermined direction relative to the base, to thereby cause the inner cable to slide to be pulled in the direction away from the parking mechanism.

In an electronic parking lock apparatus, a relative rotation angle of an electric motor of an actuator is detected by a relative rotation angle sensor, an absolute rotation angle of the electric motor is calculated according to the relative rotation angle and reference rotation position information obtained by a rotation end limiting portion that limits a rotation end of a rotating component. An absolute rotation angle of the rotating component is detected by using an absolute rotation angle sensor, and the working status of the parking lock is determined according to the absolute rotation angle. The rotation end limiting portion used for obtaining the reference rotation position information of the relative rotation angle sensor and a detected component used for enabling the absolute rotation angle sensor to work to obtain the absolute rotation angle are provided in the same rotating component.

Methods and apparatus for a lawn maintenance vehicle park brake and traction drive interlock are provided. A park brake mechanism is selectively operable between an engaged position and a disengaged position. A traction drive is also mounted to the lawn maintenance vehicle, the traction drive having a disable mode which prohibits transmission of a driving force from the traction drive to a drive wheel. A first operable connection between the park brake mechanism and a wheel brake activates the wheel brake. A second operable connection between the park brake mechanism and the traction drive activates the disable mode of the traction drive. A method of controlling a lawn maintenance vehicle with a park brake and traction drive interlock include the steps of providing a lawn maintenance vehicle, providing an operable park brake mechanism, providing a first operable connection, and providing a second operable connection.

Described herein are latching devices where relative speed of movement between members is in part controlled or reduced via eddy current formation and in part controlled or relative motion stopped via a latch arrangement. Various embodiments are described, one being use of a conductive member; at least one magnetic field and a latch member that, prior to latching, moves independently to the at least one conductive member. A kinematic relationship exists between the conductive member and at least one magnetic field that enables the conductive member to move at a different speed relative to the magnetic field on application of an energizing force, thereby inducing an eddy current drag force by relative movement of the conductive member in the magnetic field. The eddy current drag force resulting causes movement of the conductive member causing the conductive member to engage the latch member thereby halting movement between the at least one conductive member and the at least one latch member.

A park lock apparatus and control unit for a vehicle, the apparatus comprising: a locking member (28, 30; 50) having: a first state arranged to permit independent rotational movement of front and rear drive shafts (20, 22) of the vehicle relative to a fixed position on the vehicle; a second state arranged to prevent independent rotational movement of the front and rear drive shafts of the vehicle relative to the fixed position on the vehicle; and a third state arranged to prevent rotational movement of the front and rear drive shafts of the vehicle relative to the fixed position on the vehicle, and an actuation member (36; 64) for moving the locking member between the first, second and third states.

A power transmission device includes a planetary gear, a reduction gear connected downstream of the planetary gear, a parking lock mechanism including a parking pawl configured to lock one rotation element of the planetary gear, and a barrier wall positioned between the planetary gear and the reduction gear. The parking pawl is rotatably supported on the barrier wall.

A lever (3) for the temporary disengagement of a parking lock (2) of a vehicle drive unit (1). The lever (3) comprises a fixing piece (31) for fitting the lever (3) onto a parking lock shaft (26), which extends inside the vehicle drive unit (1) and serves to actuate the parking lock (2). The lever (3) is a hand lever with a gripping handle (32). The gripping handle (32) is designed to enable a user to apply a manual force for manual actuation of the lever (3). When the lever (3) is fitted on the parking lock shaft (26) and moved, the parking lock shaft (26) is moved from an engagement position to a disengagement position,. In the disengagement position, by further movement of the gripping handle (32) into a locking position, the lever (3) is blocked against a reverse movement out of the disengagement position.

A magnetic lock device includes a lock shaft having an abutting portion capable of abutting against a roller of a piston rod of a hydraulic pressure actuator, a transfer shaft configured separately from the lock shaft, the transfer shaft abutting against an end surface of the lock shaft, and a magnetic portion locking (restricting movement to the right side in the drawing) the lock shaft, the transfer shaft, and a plunger by attracting the plunger toward an attracting portion using a magnetic force. The lock shaft is surface-hardened to have a higher hardness and the transfer shaft is made of non-magnetic material.

A trailer device is provided with pressure washing features and devices. The trailer device is convertible between at least a first and mode of transport, wherein a first mode comprises a towing mode, and a second mode comprises a push or manual operation mode. The device also comprises various on-board features and control systems such that a fully-functional pressure washing unit is provided that is easily transporting between locations.
