Problems solved by technology

[0002] As people have increasingly stringent requirements for the driving and riding comfort of vehicles equipped with manual transmissions, more and more consumers complain that: when the driver drives the vehicle to shift gears in the low-speed and low-gear range, if the clutch is lifted too quickly, it will cause The vehicle rolls back and forth, which greatly affects the driving and riding comfort. This problem is common in all vehicles equipped with manual transmissions

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0024] Such as figure 1 The shift shock mitigation system shown for a vehicle equipped with a manual transmission, such as figure 1 As shown, it includes a vehicle driving state information acquisition module 1, a target speed calculation module 2, a target engine speed limit judgment module 3 and a gear shift speed control module 4, wherein the vehicle driving state information acquisition module 1 is used to obtain vehicle The vehicle speed signal, slope signal, acceleration signal, target gear signal and clutch signal at the current moment; the target speed calculation module 2 is used to calculate the engine target speed signal according to the transmission ratio and the vehicle speed signal corresponding to the target gear signal at the current moment of the vehicle The target engine speed limit judgment module 3 is used to judge whether t...

Abstract

The invention discloses a gear shifting impacting weakening system for a vehicle provided with a manual transmission. The gear shifting impacting weakening system for the vehicle provided with the manual transmission is characterized by comprising a vehicle driving state information acquiring module, a target rotating speed calculating module, a target engine rotating speed limiting value judgingmodule and a gear shifting rotating speed control module. According to the gear shifting impacting weakening system for the vehicle provided with the manual transmission, before a clutch is jacked upduring gear shifting, the engine rotating speed is increased or decreased to a target rotating speed, it is achieved that the engine rotating speed, a transmission ratio and a vehicle speed are matched during gear shifting, and the power assembly system impacting caused when the engine rotating speed, the transmission ratio and the vehicle speed are not matched during gear shifting is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a system and method for reducing shift shock of a vehicle equipped with a manual transmission. Background technique [0002] As people have increasingly stringent requirements for the driving and riding comfort of vehicles equipped with manual transmissions, more and more consumers complain that: when the driver drives the vehicle to shift gears in the low-speed and low-gear range, if the clutch is lifted too quickly, it will cause The vehicle moves back and forth, which greatly affects the driving and riding comfort. This problem is common in all vehicles equipped with manual transmissions. Contents of the invention [0003] The object of the present invention is to provide a system and method for reducing shifting impact of a vehicle equipped with a manual transmission. [0004] In order to achieve this goal, the present invention designs a gearshift shock mitigat...
