Embodiment Construction

[0033] In order to control the controllable clutch 1 , a control device is used which is designated as a whole by 2 , which transmits an assignment Xemb,cons of the position of the clutch control device from the clutch. The clutch control device 2 receives the torque assignment Cemb,cons for the clutch at the input. In order to determine the position assignment Xemb,cons of the clutch control device, the clutch control device 2 comprises a first loop called closed loop, which allows to measure the effective position Xemb,mes of the actuator of the clutch according to the measured motor torque Cmot and the clutch input The motor speed Wmot of the drive motor for the input torque of the shaft estimates the torque effectively transmitted by the clutch when the clutch is operating in a slipping state, said estimate gives the value compared to the clutch assignment given by the control system of the traction chain Value Cemb, bf. Such an estimation, which uses in particular the dy...

Abstract

The invention relates to a method for controlling a connecting device between an input shaft driven by a motor and an output shaft which can transmitting a maximum torque (Cemb) according to the position (Xemb) of an actuator of the connecting device. The control method comprises a law of behavior (Cemb=Cemb (Xemb; t)) of the connecting device according to the time which connects the maximum torque value and the value of the position of the actuator of the connecting device. According to the method, the maximum torque value to be transmitted is defined at every instant, the actual position (Xemb, mes) of the actuator of the connected device is measured. Through the maximum torque value ( Cemb, cons) to be transmitted, the measurement of the actual position (Xemb, mes) of the actuator and the law of behavior (Cemb=Cemb (Xemb; t)) of the connecting device at the considering instant t, the value (Xemb, cons) of the actuator of the connecting device is confirmed. When using the law of behavior of the connecting device at the instant t, it is obtained through the interpolation between first law (Cemb1(Xemb)) of reference of behavior of the connecting device and at least one second law (Cemb2(Xemb, Cemb3(Xemb)) of reference of behavior, with the adjustment of the interpolation of the law of behavior of the connecting device for considering the variation of the behavior of the connecting device according to the application.

Description

technical field [0001] The invention relates to a method of controlling a coupling between an input shaft driven by a motor and an output shaft capable of transmitting maximum torque, the method of controlling according to the law of the behavior of the coupling following the position of the actuator of the coupling . Background technique [0002] Control of a hybrid traction chain, for example comprising a heat engine coupled to an electric motor via a clutch and driving an input shaft in a gearbox, which itself drives the wheels of the vehicle, requires torque control of the motor elements, namely the heat engine and the electric motor , so as to best follow the driver's wishes expressed in the form of torque to be supplied to the wheels. [0003] In a hybrid traction chain, the torque to be supplied to the wheels is distributed between the heat engine and the electric motor according to the specific conditions of vehicle operation in order to particularly optimize the en...
