Tandem type drive-by-wire clutch system for manual transmission vehicle

Abstract

The invention relates to the technical field of vehicle intelligent driving assistance, in particular to a tandem type drive-by-wire clutch system for a manual transmission vehicle. The tandem type drive-by-wire clutch system comprises a clutch pedal, a clutch master cylinder, a drive-by-wire clutch device, a pressure sensor, a clutch slave cylinder, a clutch mechanism, a pedal position sensor and a controller. The clutch pedal is mechanically connected with the clutch master cylinder, the controller is electrically connected with a motor on the drive-by-wire clutch device, the controller is electrically connected with the pedal position sensor, and the controller is electrically connected with the pressure sensor. When the vehicle runs normally, a driver performs cooperative operation through gears and clutches, and when active braking is needed, a command of an active collision avoidance system can be received; in the active braking process of the vehicle, the clutch can be actively separated through the motor and the transmission device of the motor, and flameout of the vehicle is avoided; and meanwhile, when no active control exists, operation of the clutch is completed by the driver, and mutual influence is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicle intelligent driving assistance, in particular to a series-by-wire clutch system for manual transmission vehicles. Background technique [0002] With the rapid development of artificial intelligence technology, the development of key technologies for automatic driving and active safety of vehicles has become a hot spot for new technology companies to enhance their market competitiveness. [0003] For applications involving active safety or automatic driving technology, the control-by-wire technology of the vehicle chassis has become the key to technology application, and the current control-by-wire technology mainly focuses on three key directions: brake-by-wire, steering-by-wire and drive-by-wire, while active safety Or the field of automatic driving is also mainly used in automatic transmission vehicles or new energy electric vehicles. [0004] However, as people pay more and more attention to v...

AI Technical Summary

Problems solved by technology

For manual transmission vehicles, only brake-by-wire is solved. During the active braking process of the vehicle, since the clutch is not disengaged, the power output of the engine will not be cut off, causing the vehicle to stall.

Frequent abnormal flameouts will cause certain damage to the engine, and at the same time cause a series of problems such as accelerated growth of carbon deposits and shortened battery life
