Problems solved by technology

However, the disengagement of the centrifugal clutch requires a significant reduction in engine speed
If the engine generates a lot of uninterrupted power at a higher rpm than the centrifugal clutch engages, the transmission makes it difficult or impossible to shift into neutral or change gears

Embodiment Construction

[0016] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. figure 1 A vehicular automatic mechanical transmission system 10 using the control system and method of the present invention is illustrated. System 10 generally includes a fuel-controlled engine 12 , a centrifugal friction master clutch 14 and a multi-speed mechanical transmission 16 . Engine 12 generally includes a crankshaft 18 coupled to an input 20 of centrifugal friction primary clutch 14 . The input member 20 engages and disengages an output member 22 mounted on an input shaft 24 of the transmission 16 .

[0017] Transmission 16 can be simple type, also can be compound type, has an output shaft 26 that stretches out from transmission 16, is connected to the drive wheel of vehicle through a drive axle 28 or transfer case transmission. The transmission 16 may be fully automatic, semi-automatic, or manual assisted by a controller, as is k...

Abstract

A control system and method for controlling a vehicular automated transmission system having an internal combustion engine and a multiple speed transmission, is provided. The control system includes an ignition having an output that issues an ignition signal and a first control unit that operates the engine in response to receipt of the ignition signal. A second control unit receives input signals from various system sensors and process the signals according to logic rules to issue a command output signal. A relay interrupts transmission of the ignition signal to the first control unit in response to either the absence or receipt of the command output signal. The method includes the steps of determining if the automated transmission system is operating abnormally and interrupting transmission of the ignition signal to the first control unit when it is determined the automated transmission system is operating abnormally.

Description

technical field [0001] The present invention generally relates to an automatic transmission system for a vehicle, which includes an engine, a multi-speed / speed transmission, a centrifugal friction main clutch connecting the engine and the transmission, and a control system for controlling the output torque of the engine. Background technique [0002] Mechanical automatic transmission systems (so-called "two-pedal systems") which do not require the driver to operate the vehicle's master clutch are known. In order to simplify these systems, it is known to use a centrifugal friction clutch to drive the vehicle engine to the transmission. Centrifugal friction clutches generally include weights that pivot or rotate relative to an engine-driven input member. As the input member rotates, the weights move radially outward under the action of centrifugal force, so that the input member is connected to an output member. parts frictionally engaged. [0003] When the centrifugal frict...
