Park-lock Device Patents (Class 192/220.2)
  • Publication number: 20080093194
    Abstract: A sub-assembly for a brake transmission shift interlock system. The sub-assembly includes an inhibitor for preventing shifting of a vehicle transmission from a park position in the absence of application of a brake by a vehicle occupant, and a solenoid having a movable armature. A linkage couples the inhibitor to the armature such that movement of the armature produces a movement of the inhibitor. The linkage also couples the inhibitor to the armature so as to permit movement of at least a portion of the inhibitor independent of the armature. A brake transmission shift interlock assembly and a switch assembly incorporating the sub-assembly are also provided.

  • Patent number: 7278526
    Abstract: The invention provides a brake-transmission interlock system for a vehicle. The brake-transmission interlock system prevents the driver from shifting out of a park transmission position with a selector lever unless at least one brake of the vehicle is engaged. The brake-transmission interlock system includes a locking member operable to move to a locked position wherein movement of the selector lever is prevented. The locking member can move to the locked position from an unlocked position wherein the selector lever is moveable to shift out of the park transmission position. The brake-transmission interlock system also includes an indicating device operable to communicate a signal corresponding to the park transmission position to the driver. The locking member is in the locked position prior to the signal being communicated.

  • Patent number: 7204785
    Abstract: The methods and devices for actuating a parking brake in a gearbox which is actuated in an automated manner, whereby gear changes are carried out by means of at least one electrically driven actuator, gear positions can be selected by means of a selector device, and the parking brake can be activated by means of the selector device when the vehicle is stationary or moving slowly. The invention also relates to a vehicle provided with an additional gearbox. The ignition key can only be removed, when the gearbox is in the P state and the additional gearbox is not in the N state. The further method and device, whereby the additional gearbox can only be shifted in the N state when the gearbox is not in the P state. The methods and a device for carrying out the same, by automated manual gearboxes, especially parallel gearboxes, are controlled in such a way that the vehicle can be safely parked and can set off in a reliable and comfortable manner.

  • Patent number: 7152725
    Abstract: A control system for a transmission (T/M) including a select lever (r) operable to shift from a neutral position (N) to a running position (D, R) and vice versa, and a control part (c) to control a changing gear operation of the transmission in accordance with the position of the select lever. The control part includes a changing gear limitation system (1), and when the select lever is shifted from the neutral position to the running position, the changing gear limitation system permits a gear-in operation of the transmission if a stationary time (T) during when the select lever is in the neutral position is equal to or less than a predetermined time, and holds the transmission in the neutral state if the stationary time exceeds the predetermined time. By this constitution, the direction of the driving force can be quickly reversed.

  • Patent number: 7137499
    Abstract: The invention provides an apparatus for shifting an automatic transmission having a shift position select lever. The invention selectively shifts the transmission to one of a plurality of different transmission shift positions. The invention includes a steering column positionable in a passenger compartment of a vehicle. A switch is mountable in the passenger compartment of the vehicle and operable to emit a first signal representative of a desired change with respect to a transmission shift position. A motor generates a moving force and a linkage associated with the motor to transmit the moving force from the motor to a shift lever of a transmission of the vehicle. A sensor is responsive to a current transmission shift position and emits a second signal corresponding to the sensed current transmission shift position. A controller is responsive to the switch and to the sensor.

  • Patent number: 6827195
    Abstract: The present invention pertains to a locking and unlocking mechanism, which is equipped with an electromagnet (1) and is used preferably to embody a key and/or shift lock function in motor vehicles. Its basic object is to design such a mechanism such that the generation of noise during the transition from one state into the other is reduced compared with prior-art solutions. To accomplish the object, a pulsating voltage in the form of a direct voltage-rated pulse width signal (PWM voltage) is sent to the electromagnet (1). The effective value of the PWM voltage is increased over at least three voltage pulses from an off-load voltage value to a preset final voltage value at the beginning of a phase of energization and it conversely drops, again over at least three voltage pulses, to the off-load voltage value at the end of the phase of energization, in a time-controlled manner by means of a circuit unit (2) associated with a pulse width modulator (3).
