Abstract

The invention provides a hybrid power vehicle clutch electromagnetic valve clamping stagnation handling method, a system and an automobile. The method includes the following steps that whether a clutch electromagnetic valve is subjected to clamping stagnation or not is detected; in response to clamping stagnation of the clutch electromagnetic valve, the current operating mode of a vehicle is detected, and operating modes include a pure electric mode, a range extending mode and a hybrid power mode; first preset currents are utilized and last for first preset time to periodically flush the electromagnetic valve, if the clamping stagnation fault disappears after flushing, the vehicle resumes normal operation, otherwise, an electromagnetic valve fault signal is generated; and according to theelectromagnetic valve fault signal and the current operating mode of the vehicle, a preset algorithm corresponding to the current operating mode of the vehicle is utilized to control the vehicle to continue operating. The system is used for implementing the method. The automobile comprises the system. By applying the method, the problem of hybrid power vehicle clutch electromagnetic valve clampingstagnation fault handling can be solved, and safe operation of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of hybrid vehicles, in particular to a method and a system for processing stuck solenoid valves of a hybrid vehicle clutch, and an automobile. Background technique [0002] As fuel consumption and emission standards become more and more stringent, reducing fuel consumption has become the research and development focus of various automobile manufacturers, and the development of new energy vehicles has become an important trend at present. Hybrid vehicles use engines and drive motors as power sources, which can realize pure electric drive at low speeds and parallel drive at high speeds, which effectively reduces fuel consumption and emissions, and also provides a good power performance for vehicles. Among them, the hybrid electric vehicle with the engine and the drive motor as the power source needs to engage the clutch when driving in parallel. The clutch is engaged and disengaged using hydraulic drive, which...
