[0036] A first embodiment of the present invention will be described below. figure 1 A schematic diagram of a vehicle control system is shown, in which the clutch control device according to the first embodiment of the present invention is applied. In this vehicle control system, an automatic clutch mechanism 20 is provided on a flywheel 10 a integrally connected and rotated with an output shaft (crank shaft) of an engine (internal combustion engine) 10 . The automatic transmission mechanism 30 is connected to the output shaft of the engine 10 through the automatic clutch mechanism 20 .

[0037] The engine 10 is connected to an ignition switch 11 for igniting the engine 10, an engine rotation sensor 16 for detecting the engine rotation rpm Ne, and an engine water temperature sensor 17 for detecting the engine water temperature Tw.

[0038] The automatic clutch mechanism 20 comprises: a mechanical type (dry single plate type) friction clutch 21; A clutch lever 22; The state o...

[0101] A second embodiment according to the present invention will be described below. In the second embodiment, the calculation of the reflection rate is changed only according to the clutch torque value at the learning point (see image 3 with Figure 9 Steps 404 to 406 in ), and other structures are the same. Therefore, detailed descriptions of the same parts are omitted. The reflection rate is calculated (corrected) from the clutch torque value at the learning point. The ECU 50 according to the second embodiment includes a reflectance correction means in combination with other structures.

[0102] The case where the reflection rate calculation is performed without referring to the numerical value at the learning point will be described below. exist Figure 11 , the thick solid line corresponds to a reference clutch torque map (initial clutch torque map, in Figure 11 referred to as the reference map in ), the thin solid line corresponds to a target actual clutch torq...

Abstract

A clutch control device configured to obtain a target clutch torque by controlling an actuator to a target control amount based on a clutch torque map formed by a clutch torque and a control amount ofthe actuator, is characterized in that the clutch control device including a first calculation means for calculating a first correction modulus indicating a deviation between the target clutch torqueand an estimated clutch torque which is outputted when the actuator is activated to obtain the target control amount under a predetermined condition, a second calculation means for calculating a second correction modulus for each predetermined clutch torque based on the first correction modulus and a reflection rate defined by a deviation from a predetermined point on the clutch torque map as a reference point, and a correction means for correcting the clutch torque map by correcting each control amount of the actuator corresponding to each predetermined clutch torque based on the second correction modulus of each predetermined clutch torque.

Description

technical field [0001] The present invention generally relates to a clutch control device. In particular, the present invention relates to a clutch control device for changing clutch torque by controlling an actuator. Background technique [0002] Known is an automated system in which an actuator is connected to an existing manual transmission (manual transmission) to perform a series of shifting operations (ie, clutches, transmissions and gear selectors ( gear selection) engagement and disengagement). For example, the automated system disclosed in Japanese Patent Publication No. 2003-56600. [0003] In this system, for example, the clutch is controlled by a clutch stroke. The clutch stroke is an actuator control amount for the clutch, and is converted from a transmission torque (clutch torque) between a flywheel and a clutch disc required according to vehicle characteristics. To switch from transmission torque to clutch travel, a clutch torque map is used. [0004] The...
