Abstract

The present invention belongs to the technical field of vehicle fault handling. The present invention provides a clutch fault processing method. The present invention also provides a controller and a vehicle. The clutch fault processing method is used to handle the clutch fault of the gearbox. The clutch failure processing method includes the following steps: receiving the current gear signal of the gearbox and the operating state signal of the clutch; according to the result that the current gear signal and the operating state signal are in a fault state, limiting the shifting The required transmission ratio of the gearbox is within the preset transmission ratio range corresponding to the next gear of the current gear. In the clutch fault handling method proposed by the present invention, when the clutch is faulty, the gearbox adopts a step-by-step downgrading method to downshift, so as to avoid the problem that the clutch directly jumps back to neutral when the fault occurs, which is likely to cause potential safety hazards.

Description

technical field [0001] The invention belongs to the technical field of vehicle fault handling, and in particular relates to a clutch downshift control method. The invention also relates to a controller and a vehicle. Background technique [0002] This section provides merely background information related to the present disclosure and is not necessarily prior art. [0003] At present, when a vehicle is driving on a slope, when the gear clutch fails, it generally jumps back to neutral, causing the vehicle to slide and jeopardizing the personal safety of the driver. In addition, when driving on a high-speed curve, the high-speed clutch directly jumps back to neutral when it fails, which is likely to cause safety hazards or traffic congestion to other high-speed vehicles. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to at least solve the problem in the prior art that the gear clutch of the vehicle directly jumps back to neutral when it fails, an...
