The invention provides a clutch engagement position determination method and device, and the method comprises the steps: obtaining the weight value of a vehicle and the slope value of a lane where the vehicle is located, determining the clutch displacement according to the weight value, the slope value and a first corresponding relation, and determining the target engagement position of a clutch through the clutch displacement. The clutch displacement represents the idle stroke of a driving disc and a driven disc of the clutch from complete separation to joint, the target joint position is the preset joint position of the clutch, the idle stroke of the clutch can be determined by utilizing the weight of the vehicle and the slope value of the lane in combination with the first corresponding relation, and then the preset joint position of the clutch is determined according to the idle stroke. After the predetermined engagement position is determined, the clutch can be subsequently adjusted to the predetermined engagement position in advance, so that when a user starts the vehicle, the clutch can be engaged in time to provide power for the vehicle, and the problem of poor dynamic property caused by slow engagement of the clutch in a hybrid power mode is solved.
Description
technical field [0001] The invention relates to the field of vehicles, in particular to a method and a device for determining the engagement position of a clutch. Background technique [0002] With the development of related technologies, hybrid vehicles are also developing rapidly. Hybrid vehicles have the advantages of energy saving and low emission. The hybrid vehicle not only has the advantages of long continuous working time of the engine and good power performance, but also combines the advantages of no pollution and low noise of the electric motor, so it has gradually become a vehicle favored by users. [0003] However, there is a problem of poor dynamic performance in hybrid vehicles. Contents of the invention [0004] In view of this, the purpose of the present application is to provide a method and device for determining the engagement position of the clutch, which can determine the engagement position of the clutch in advance, so that the clutch can be engaged...
