Embodiment Construction

[0020] With reference to the accompanying drawings, the thermal protection method according to the invention for a clutch device 1 of a vehicle, in particular a motor vehicle, which is in an automatic driving mode for parking in order to stop will now be described.

[0021] The vehicle comprises a heat engine 3 and a gearbox 2 comprising control means, such as a computer containing storage space, adapted to control a clutch device 1 arranged between the gearbox 2 and the heat engine 3 . Therefore, the clutch device 1 is not under the control of the driver of the vehicle.

[0022] The clutch device 1 comprises at least one clutch plate 4 integrally connected with the input shaft 5 of the gearbox 2 . Preferably, the clutch device 1 includes a plurality of coaxial clutch plates 4 , all of which are integrated with the input shaft 5 of the gearbox 2 . However, in the following description, for the sake of clarity, only one clutch plate 4 is mentioned although the following techni...

Abstract

The invention relates to a thermal protection method for a clutch device of a vehicle, especially a motor vehicle. The method comprises the steps of: when the transmission computer detects, at a given moment, estimated temperature data exceeding a certain critical temperature (Tc) stored in the memory space of the transmission computer and possibly damaging the clutch plates, opening the clutch device to prevent A step (E1) of transmitting torque to the gearbox through the clutch device, which step is accompanied by a step (E2) of actuating the braking device of the vehicle to stop the vehicle. The invention finds application in the field of the motor vehicle industry.

Description

technical field [0001] The invention relates to a thermal protection method for a clutch device of a vehicle, especially a motor vehicle. Background technique [0002] Motor vehicles include transmissions of the automatic or manual type. The gearbox includes a gearbox computer adapted to control a clutch arrangement including a flywheel integral with the output shaft of the heat engine and adapted to cooperate with one or more clutch plates connected to the input of the gearbox Axes are integrated. Furthermore, the vehicle includes a temperature measuring sensor for measuring the temperature inside the housing of the clutch device and is electrically connected to a transmission computer which continuously monitors the temperature measured by the sensor. [0003] In a manner known per se, when the temperature inside the clutch device exceeds a determined value depending on the position of the sensor and the technical characteristics of the clutch device, the adhesion of the...
