An apparatus for reducing a clutch pedal effort may include a switching lever that is rotatably assembled to a pedal member and selectively engaged with a pedal arm and a reaction providing unit, a first end of which is engaged with the pedal member and a second end of which is engaged with the switching lever.

An engine automatic-stop/restart system resumes injection of fuel when an engine restart condition is satisfied, and energizes the starter motor when, after injection of the fuel has resumed, starting of the engine is not completed. The system can also control the coupling degree of a forward clutch under certain conditions, and energize a solenoid to engage a starter pinion with a crankshaft ring gear when their relative speeds are close to each other. The system then releases the forward clutch after the pinion and the ring gear have engaged.

A transmission for a work machine is disclosed. The transmission has a source of pressurized fluid, a low pressure reservoir, a plurality of hydraulically actuated clutches, a first plurality of valve mechanisms, and a second plurality of valve mechanisms. Each of the first plurality of valve mechanisms is associated with one of the plurality of hydraulically actuated clutches and configured to selectively fill and drain the associated one of the plurality of hydraulically actuated clutches. Each of the second plurality of valve mechanisms is associated with one of the plurality of hydraulically actuated clutches and configured to selectively fill and drain the associated one of the plurality of hydraulically actuated clutches. The transmission also includes a master latch mechanism in fluid communication with only the second plurality of valve mechanisms. The master latch mechanism is configured to selectively affect movement of the second plurality of valve mechanisms in response to an electrical power failure.

In an automatic transmission having a clutch and a gear type transmission, when it is determined that a driver has an intention to stop a vehicle, the clutch is disengaged and the gear type transmission is changed to its neutral position. Thereafter, the clutch is held in its disengaged state, and when an accelerator opening amount is greater than or equal to a predetermined value, the gear type transmission is changed to gear according to a vehicle speed to engage the clutch. Under a condition such that a drive has an intention to decelerate the vehicle, when it is determined that an engine is in an idle-up state and when it is detected that the vehicle speed is less than a predetermined value, changing of the gear type transmission to its neutral position occurs. Whether or not the engine is in the idle-up state is determined by the amount of fuel injection. In a multi-stage transmission in which a range type sub transmission is connected to a main transmission and, changing of the sub transmission takes place while the main transmission is held in its neutral position, during a vehicle stopping if changing operation of the sub transmission is not completed within a predetermined time lapse, a determination is made that a batting state occurs in the sub transmission to start the changing of gear by the main transmission.

In a method of operating a motor vehicle with an electronically controlled automatic clutch device, a control device and one or more data-storing devices for values of operating quantities and parameters, the values are stored in at least duplicate form in the data-storing device. The data are stored in prescribed formats and the integrity of the data is checked according to prescribed criteria, to ensure that incorrect data are not used in the operation of the vehicle.

An electrohydraulic clutch includes a bi-directional electric motor, a hydraulic circuit and a multiple plate friction clutch pack. The bi-directional electric motor drives a ball screw through a gear reduction assembly. The ball screw output translates a master piston of the hydraulic circuit which in turn advances and retracts an annular sleeve piston disposed adjacent the friction clutch pack. Hence, actuation of the electric motor displaces hydraulic fluid and compresses or relaxes the friction clutch pack, thereby transferring or inhibiting torque.

A control pedal assembly includes an eccentric curve as an actuator surface at one end of a pedal arm and a control member includes a first lobe with a roller that rides on the actuator surface and a second lobe that receives a connector rod to a control device to be controlled by the pedal. The eccentric curve changes the stroke ration between the pedal stroke and the connector rod stroke as the pedal is depressed. Designers can simply and efficiently vary the stroke ratio as desired by selecting an appropriate curve for the actuator surface.

A vehicle safety device includes a seat mounted within a passenger compartment of the vehicle, in which the seat is movably connected to a vehicle frame by a seat position adjusting mechanism that allows the seat to move along an axis between a forward-most position and a rearward-most position. An air-bag is mounted within the passenger compartment in front of the forward-most position of the seat, with the forward-most position of the seat defined as a position of the seat in which a distance between a passenger seated in the seat and the air-bag is equal to a minimum safe clearance. In addition, an exemplary method of maintaining a minimum safe clearance between an air-bag mounted in a vehicle and a vehicle passenger includes the steps of preventing motion of a seat toward the air-bag beyond a forward-most position, in which, when in the forward-most position, a passenger seated in the seat is separated from the air-bag by a predetermined minimum safe clearance, and providing a position adjusting mechanism for at least one vehicle control pedal to allow a passenger seated in the seat to adjust a distance between the seat and the at least one pedal by moving the at least one pedal toward and away from the seat. An automatic seat positioning system, which takes into account both seat to air-bag distance and eye height and automatically, may be used to optimally and automatically position a passenger to maximize safety and comfort.
摘要:
A pedal module adapted to be fixed to a dashboard for separating a vehicle body of an automotive vehicle into a vehicle chamber and an engine room is provided with a pedal which is operable by a stepping operation of a driver of the vehicle, a master cylinder including a cylinder body and a push rod which protrudes through an opening end of the cylinder body and is made reciprocable in an axial direction of the cylinder body in accordance with the stepping operation of the pedal by the driver, and a pedal bracket which is attached to the cylinder body for pivotally mounting the pedal thereon. The cylinder body has an attachment member on an end portion thereof opposite to the opening end in the axial direction of the cylinder body, and the attachment member is fixed to the dashboard.
