    摘要： The present invention relates to a vehicle such as a forklift in which a hydraulic pump for driving the fork is driven by the same engine used to provide motive power to the vehicle. A inching control is provided in cases where an automatic transmission is employed for shifting the gears of the vehicle. The inching control controls the clutch to allow separate control of the motive system and cargo handling system of the vehicle. This control must be operated by an operator through the inching pedal. In the fork lift, the clutch plate wears excessively and therefore the relation between the amount of depressing of the inching pedal and engagement of clutch changes abruptly. The present invention discloses a technique to adequately measure the clutch position and for compensating for control of the clutch by always keeping constant the relation between the amount of depression of the inching pedal and the amount of engagement of the clutch.

    摘要： The present invention relates to a saddle-ride type vehicle comprising a clutch assembly (4), interposed between an engine (2) and a gearbox (3), which includes a clutch device (11) in turn comprising two clutch elements (one integral with the shaft of the engine and the other with the input shaft of the gearbox) and return means (12) that keep these elements (11A, 11B) in contact in a closure condition of the clutch. According to the invention, the clutch assembly (4) further comprises an operating device (21) of the clutch device that causes detachment of the elements (11A, 11B) of the clutch device up to an opening condition of the clutch assembly. This latter further comprises a control device (6) to limit the torque peaks during gear change. This device comprises an actuation means (5) that, during gear change, exerts a predetermined force (S) in contrast to the force exerted by said return means (12) of the clutch assembly, wherein said predetermined force (S) is less than the force (F) generated by the return means (12) so as to cause a mutual slip of the elements (11A, 11B) of the clutch device (11) without said opening condition being reached. The operating device (21) is of hydraulic type and comprises a primary pump (22) operated by means of a control lever (23), wherein this primary pump (22) is hydraulically connected, through a primary hydraulic circuit (16), to a primary piston (24) acting on at least one of the elements (11A, 11B) of the clutch device (11) in opposition to the return means (12) so that, following an action on the control lever (23), the primary piston (24) exerts an action the elements (11A, 11B) determining the opening condition. According to the invention, the control device (6) comprises a secondary piston (25) connected to the primary piston (24), wherein the actuation means (5) exerts, directly or indirectly, the predetermined force (S) on the secondary piston (25), said predetermined force (S) being transferred to the primary piston (24) in opposition to the force (F) of the return means (12).

    摘要： Electronic pedal control systems and methods for a vehicle are provided. One electronic pedal control system includes a first sensor configured to produce a first output corresponding to a user applied force and a second sensor configured to produce a second output corresponding to a release of user applied force. A controller is configured to receive the first output and the second output and to control one of a brake system, a clutch system, and a throttle system of the vehicle based on the first and second outputs, and the first and second sensors are positioned relative to one another such that an application of force to the first sensor unloads the second sensor and the removal of force from the first sensor loads the second sensor.
