Problems solved by technology

[0006] However, this document does not address the possibility of the driver maintaining control of the clutch operation with the actuation pedal of the clutch, while at the same time facilitating advanced assistance functionalities, such as free wheel action, known in English as "coasting" and "freewheeling", in motor vehicles Under certain conditions, the crankshaft of the internal combustion engine is separated from the input shaft of the gearbox, and the internal combustion engine is shut down to reduce fuel consumption and reduce carbon dioxide emissions

Embodiment Construction

[0070] Such as figure 1 As shown, the motor vehicle has an internal combustion engine 1 , the output shaft or crankshaft of which is connected to the input shaft 3 of a gearbox 2 via a clutch 4 . Normally, the torque transmission between the crankshaft and the input shaft 3 of the gearbox 2 is ensured when the clutch 4 is in the engaged position and terminated when the clutch 4 is in the disengaged position.

[0071] The motor vehicle has a clutch actuation pedal 19 mounted to pivot on the chassis of the motor vehicle between an inoperative position and a depressed extreme position. The clutch actuation pedal 19 is connected to a position sensor 20 which can signal the position of the pedal 19 . The clutch driver 14 can act according to the position of the clutch release bearing to move the clutch 4 from the engaged position to the disengaged position, or vice versa from the disengaged position to the engaged position. The clutch drive 14 is connected via a power supply netw...

Abstract

The invention concerns a method for controlling a clutch (4) mounted between the output shaft of an engine and the input shaft (3) of a gearbox of a motor vehicle by means of a clutch actuation pedal (19), and an associated position sensor (20); a clutch actuator (14) and a control unit (17) arranged so as to control the actuator (14), in a manual control mode, on the basis of the pedal position signal, and, in at least one assistance mode, to automatically control the actuator (14) when the clutch actuation pedal (19) remains in the idle position of same; said control method involves activating the assistance mode in which the actuator (14) is automatically set to the disengaged position of the clutch in response to the detection of characteristic driving conditions and the idle position of the pedal (19).

Description

technical field [0001] The invention relates to an actuation method and an actuation system for actuating a clutch. [0002] The invention relates in particular to clutches, the actuation of which can be ensured by an actuator connected to a drive pedal connected to a position sensor in order to allow the driver to maintain control of the clutch operation while facilitating the auxiliary functionality of the control clutch . Background technique [0003] In the prior art, the control method of the clutch is known, wherein the clutch is composed of a driving pedal connected with a position sensor, an electromechanical drive for moving the clutch between the engaged position and the disengaged position, and an The position of the pedal is controlled by a control unit that sends a control signal to the drive. [0004] Such a manipulation method is described, for example, in document FR2812919. The control method described in this document improves the comfort, precision and ...
