摘要:
A pressure sensor detects the change in pressure within a cylinder in a clutch master cylinder in a case where a clutch shifts from a connected state to a disconnected state. The pressure within the cylinder is detected at a time point where a rate of pressure increase is changed. The position L1 of a rod in this case or the rotation angle of a motor in an actuator is detected as a touch point preparation position. The touch point preparation position is a preceding stage in which power generated by an engine is transmitted to the clutch. The actuator moves the rod at high speed until the position of the rod reaches L1.
摘要:
The present invention relates to a device for controlling connection and disconnection of a clutch by means of a clutch actuator, wherein the clutch actuator is controlled based on a difference in rotating speed between drive side and driven side of the clutch.

The present invention relates to a shift change process for an automated manual transmission unit of a vehicle, said transmission including a friction clutch and a dog-clutch type transmission, said shift change process comprising a gear change assist control adjusting the engagement condition of the clutch, in that the clutch is connected at a first speed (speed A), and upon reaching a reference clutch position, the clutch is further connected at a second speed (speed B) lower that the first speed to establish a dog-contact condition to apply a rotational driving force to a follower side of a friction clutch so that a first gear and a second gear of a dog-clutch-type transmission can rotate relative to each other.

The present invention relates to a method to automatically control a power transmission of a vehicle, in particular of a saddle-riding type vehicle, performing on and off operation of a friction clutch provided between a driving side power transmission mechanism and a driven side power transmission mechanism, and shifting of gears of a transmission, wherein a clutch connecting speed is controlled on the basis of a reduction rate of a difference in rotational numbers of the driving side power transmission mechanism and the driven side power transmission mechanism during half-clutch control

A clutch engagement control device capable of engaging a clutch without shock and quickly even when a clutch engagement starting point changes. A clutch engagement control device (100) engaging a friction clutch (1) using an actuator (3), wherein a magnetostrictive sensor (71) detects the power transmission condition of the friction clutch (1), and the speed of the engagement of the friction clutch (1) is made a first engagement speed until the magnetostrictive sensor (71) detects the start of transmission of the power and changed to a second engagement speed slower than the first one when the magnetostrictive sensor (71) detects the start of transmission of the power so as to gradually increase the power transmission rate by starting the power transmission of the friction clutch (1) from the power non-transmission state of the friction clutch (1).
摘要:
A vehicle equipped with a system (30) for automatically disengaging and engaging a friction clutch (13) coupling between an engine (11) and a transmission (16). The vehicle is also equipped with an automatic brake system (34) for automatically applying and releasing a brake to and from wheels (43). The automatic clutch disengagement/engagement system (30) performs high speed clutch engagement at the time of restarting the vehicle. The automatic brake system (34) releases the brake upon completion of the quick clutch engagement. The quick clutch engagement occurs in a clutch play range. The amount of quick clutch engagement is determined by depression of an accelerator pedal (10). Since the accelerator depression varies from when the vehicle is started on a flat road to when on an inclination, an optimum brake releasing is effected regardless of the road inclination if the timing of brake release is determined in this manner.
摘要:
A system is described for controlling an electromagnetic clutch for a motor vehicle when the motor vehicle is started. In a control unit (20) an actual clutch engagement degree or rate is obtained by means (43), in dependence on speeds of a drive member and a driven member of the clutch. A desired engagement degree or rate of the clutch is determined by other means (44) in accordance with load on the engine and the speed of the driven member of the clutch. Clutch current is controlled by a controller (45, 46) so as to converge the actual engagement degree rate on the desired engagement degree or rate, and thereby the clutch is smoothly engaged when the vehicle starts.
