Abstract

The invention belongs to the technical field of vehicle fault processing, provides a clutch fault processing method, and further provides a controller and a vehicle. The clutch fault processing methodis used for processing clutch faults of a gearbox. The clutch fault processing method comprises the following steps: receiving a current gear signal of the gearbox and a running state signal of a clutch; and limiting a required transmission ratio of the gearbox to a preset transmission ratio range corresponding to the next-stage gear of a current gear according to the result that the current gearsignal and the running state signal are in the fault state. According to the clutch fault processing method, when the clutch breaks down, the gearbox is subjected to downshifting by a step-by-step downgrading method, so that the problem that potential safety hazards are likely to be generated due to the fact that the clutch directly jumps back to the neutral gear when breaking down is solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle fault processing, 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 background information related to the present disclosure only and is not necessarily prior art. [0003] At present, when the vehicle is driving on a slope, when the gear clutch breaks down, it will generally jump back to neutral gear directly, causing the vehicle to slide down the slope and endangering the personal safety of the driver. In addition, when driving on a high-speed curve, if the high-gear clutch breaks down and jumps directly back to neutral, it will easily cause safety hazards or traffic jams to other high-speed vehicles. Contents 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 jump...
