Description:CLUTCH PEDAL OVERIDING INDICATION DEVICE AND OPERATION METHOD THEREOF
FIELD OF INVENTION
The present invention generally relates to the field of mechanics. Specifically, the present invention relates to dual-clutch transmissions. More specifically, the present invention relates to the dual-clutch transmissions for motor vehicles. Particularly, the present invention relates to a method of operation of overriding indicator for vehicles.
BACKGROUND OF THE INVENTION
In general, manual transmission is operated manually by a driver of a vehicle to control a gear ratio for transferring drive torque from an engine to a driveline. The driver operates a clutch pedal that in turn controls engagement/disengagement of a clutch assembly (a clutch disc and a pressure plate) in the manual transmission. A clutch interlock switch detects contact with the clutch pedal and outputs an on/off state. The on state of the clutch interlock switch is indicative of a fully depressed clutch. When the clutch interlock switch is in the off state, the engine is prevented from starting because the clutch pedal is assumed to not be fully-depressed. When a false malfunction of the clutch interlock switch is detected, however, the engine could potentially inadvertently be prevented from starting. This potential scenario could be undesirable for vehicles equipped with an electronic stop-start (ESS) system that repeatedly stops and starts the engine.
There are few of the reports available in the state of art about the existence of indicator devices for overridden vehicles.
US20220397165A1 discloses the working of vehicle and tractor, the present invention includes a clutch displaceable to a connected state in which power is transmitted to a drive, a disconnected state in which the transmission is disconnected, and a half-clutch state in which power is slidably and partly transmitted to the drive; a detector that detects an operation position of a clutch pedal and outputs a detected value corresponding to the operation position detected; a control device that brings the clutch into the half-clutch state if the detected value corresponds with a threshold, and brings the clutch into the disconnected state if the detected value is less than the threshold and into the connected state if the detected value is greater than the threshold, and vice versa; and a change unit that changes the threshold to a different value in accordance with an operation on the operation member.
US4555006A discloses an automatic engine stop and start system, the invention includes clutch operation signal issued in operational association with depression of a clutch pedal are taken as answer-back signals into an electronic control unit (ECU), a starter start command signal is issued in response to one of these answer-back signals. Additionally, a clutch upper switch and a clutch lower switch, which constitute a clutch sensor and are connected in series to each other, are inserted into a starter relay driving system, so that start due to mistaken operation and the like of ECU can be avoided.
US7807936B2 discloses a device for mounting a pedal switch to a vehicle, the invention includes to improve productivity and maintain a predetermined switch contact gap between a sensing rod and a stopper after mounting the pedal switch in order to accurately detect the operational conditions as the pedal arm is operated, by fastening a pedal switch to a mounting bracket fixed to the car body in one touch insertion way.
