Problems solved by technology

However, due to the operator's reasons, the brakes are often applied without depressing the clutch pedal to disconnect the clutch
When the vehicle speed is high or the clutch is not disengaged for braking, the vehicle will not stall unexpectedly, but when the vehicle speed is low, if the clutch is not disengaged for braking, the engine will stall due to excessive resistance
There is no corresponding device in the prior art to prevent this problem

Abstract

The invention provides an automatic on-off system, which comprises a brake pedal sensor, a gear position sensor, a vehicle speed sensor, a sensor for the rotating speed of an engine, an electronic control unit and an on-off performer. The invention uses the electronic control unit to carry out analyzing according to the position of the brake pedal, the speed, the rotating speed of the engine and a gear position signal collected by the sensors, operates and controls the brake performer to move according to set conditions, realizes braking and simultaneously to pause the power output of the engine and prevents the engine from accidental flameout. The system can improve the driving safety and prolong the service lives of the engine and a starter of the engine; besides, the system has the advantages of simple structure, being flexible to control and lower manufacture cost.

Description

technical field [0001] The invention relates to an automatic clutch system. Background technique [0002] The clutch is a component directly connected to the engine in the car transmission system. The car must cut off the power transmission before starting, shifting and braking. Reflected on the operation, it is necessary for the operator to depress the clutch pedal to disconnect the clutch. However, due to the operator's reasons, braking is often implemented without depressing the clutch pedal to disconnect the clutch. When the vehicle speed is high or the clutch is not disengaged for braking, the vehicle will not stall unexpectedly. However, when the vehicle speed is low, if the clutch is not disengaged for braking, the engine will stall due to excessive resistance. There is no corresponding device in the prior art that can prevent the occurrence of this problem. Contents of the invention [0003] The purpose of the present invention is to avoid the problem of unexpec...
