  • Patent number: 10302195
    Abstract: A brake interlock feature prevents release of the park mechanism unless a driver is depressing the brake pedal. This is intended to prevent the vehicle from rolling following park release. An enhanced brake interlock feature also checks to ensure that adequate brake boost is available to prevent vehicle roll before releasing the park mechanism. The feature may directly measure brake boost or may measure a quantity indirectly related to the availability of brake boost such as engine speed.

  • Patent number: 9529378
    Abstract: A shift lever assembly may be used to shift among gears of a vehicle transmission. The shift lever assembly may be of a so-called shift-by-wire type where a shift lever is not directly mechanically coupled to the transmission but is electrically communicated with the transmission to effect transmission gear changes. A driver may move the shift lever through a shift stroke to cause a transmission gear change, and, for example, when the driver releases the shift lever, an actuator may automatically return the shift lever to a home position during a return stroke. The shift lever assembly may include feedback features that provide feedback to the driver that the shift lever is moving among various positions during the shift stroke, and the assembly may be configured so that the shift lever returns to the home position with less or no feedback features being encountered during the return stroke.

A shaft is inserted into, and penetrates through, the plunger and a buffer member is disposed at an end of the shaft exposed from the plunger. An elastic member is disposed between the buffer member and an end of the aperture. The plunger moves toward the core due to combined forces obtained by combining forces applied in a direction of the movement of the plunger by a magnetic field generated by the current and attractive forces generated vertically between the plunger and the core.

  • 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).

    Abstract: A drivig rotary shaft and a follower rotary shaft are rotatably carried in a housing of a rotary solenoid. Operating members fixed to the rotary shafts by clips are operatively connected to each other by gears, and a locked member is locked non-movably by locking surfaces formed at tip ends of the operating members. This makes it unnecessary to provide a device for converting a rectilinear motion to a rotational motion such as a pin and an elongated bore in a path of transmission of a driving force from the rotary solenoid to the operating members. Therefore, not only the number of parts and the number of assembling steps are reduced, but also the number of slide areas, where a friction resistance and looseness are liable to be produced, is reduced, thereby enabling a noiseless smooth operation.

In the mechanism, a pair of upper and lower projections are formed the inner surface of a side wall of a housing at a location adjacent a portion of a gate opening corresponding to a parking position of a shift lever. A radial projection is formed on the shift lever in such a manner as to be capable of passing through an interval between the upper and lower projections on the side wall. A lock lever is swingably mounted on the inner surface of the side wall so as to be capable of abutting upon the projections on the side wall when the shift lever is in the parking position, for thereby preventing further movement of the shift lever.

  • Patent number: 6298742
    Abstract: A rocker has a least one rocker arm and is urged by a spring member into a rocker end position and by an electromagnetically actuated control member into an opposite rocker arm end position. The respective upwardly tilted rocker end serves as a latch for a selector element so that the adjustment movements of the selector element in one or more predetermined adjustment positions (P, R, N, D) is allowed or prevented under certain operating conditions.

  • Patent number: 6241068
    Abstract: A shift lever assembly (12) for a vehicle transmission (16) includes a housing (30), a selector lever (22) pivotally mounted with respect to the housing (20), a detent member (34), and a pawl (38). The selector lever (22) defines a longitudinal lever axis (66) along which a shift force is applied to selectively shift the transmission (16) between a plurality of shift positions. The detent member (34) is fixed with respect to the housing (30) and defines a plurality of detent gates (36) corresponding to the shift positions. The pawl (38) is mounted for movement with the selector lever (22) in and out of the detent gates (36). A roller assembly (76) is mounted to one end of the selector lever (22) and engages a stop (68). When the pawl (38) is in the park position and vehicle braking system (18) is not applied, the stop (68) prevents the lever (22) from moving longitudinally along the longitudinal lever axis (66).

  • Patent number: 6182527
    Abstract: A latching element is used for locking a selector lever in vehicles, with the latching element consisting of at least two flat elements. In order to accept high forces, and be manufactured at low-cost and to exhibit reduced noise generation in conjunction with other latching parts, the first of the flat elements is injection-coated at least areawise with elastic material and the other flat elements are coupled with the first element by the elastic material.
