Vehicle fault handling method of hydrogen energy vehicles

Abstract

The invention discloses a vehicle fault handling method of hydrogen energy vehicles. The method includes the following steps: S1, performing fault detection on components whose functions can be replaced and the components whose functions cannot be replaced; S2, sending component fault grades to a vehicle controller; S3, calculating and processing each component according to the fault grades; S4, sending the component fault grades to the vehicle controller; S5, calculating vehicle fault grades; and S6, performing vehicle fault handling. The method can detect a fuel cell and a hydrogen storage system while detecting a motor controller, a distribution box and other products, and an auxiliary power supply is also considered, so that a vehicle can be in a safe and reliable working state; and the vehicle components can be divided into products with replaceable functions and products with non-replaceable functions according to the functions, and fault detection can be respectively performed on the products with replaceable functions and the products with non-replaceable functions.

Description

technical field [0001] The invention relates to the technical field of heat supply billing methods, and in particular to a method for processing a vehicle failure of a hydrogen energy vehicle. Background technique [0002] Hydrogen vehicles are mobile vehicles that use hydrogen as the main energy. Ordinary internal combustion engines are usually injected with diesel or gasoline, while hydrogen vehicles use gaseous hydrogen instead. Hydrogen energy vehicles use hydrogen as the main energy for moving vehicles. Whereas internal combustion engines are usually injected with diesel or gasoline, hydrogen cars use gaseous hydrogen instead. Fuel cells and electric motors will replace ordinary engines, that is, hydrogen fuel cells. The principle is to input hydrogen into the fuel cell. The electrons of hydrogen atoms are blocked by the proton exchange membrane, and are conducted from the negative electrode to the positive electrode through an external circuit to become electric energ...

Problems solved by technology

[0003] With the rapid development of new energy vehicles, various controllers on the vehicle are also increasing. The stable operation of the vehicle requires the coordination and cooperation between the various controllers. When the controller fails, the vehicle also needs to target different The problem is handled differently, so that the whole vehicle is in a safe and controllable state. Due to the auxiliary power supply of hydrogen energy vehicles, the situation is more complicated. The existing vehicle fault handling methods are not refined enough to classify vehicle faults It is also impossible to divide the parts of the whole vehicle into functionally replaceable products and functionally irreplaceable products according to their functions, and then perform fault detection and fault level classification
