Abstract

The invention discloses a vehicle battery voltage automatic identification method. The vehicle battery voltage automatic identification method comprises the steps: the voltage of the two ends of a battery of a vehicle is collected through a controller of an SCR system; the voltage is subjected to AD conversion and then a corresponding voltage value is obtained; and a voltage value area of the voltage value is identified, according to the voltage value area, whether the vehicle belongs to a 12-V system or a 24-V system is judged, and then related data, post-processing control algorithms and fault diagnosis strategies are matched. The effect of the controller can be given into full play, the hardware cost is saved, the universality of a product is improved, and the universality of control software is improved.

Description

technical field [0001] The invention relates to the field of vehicle post-processing, in particular to a method for automatic identification of vehicle battery voltage. Background technique [0002] Vehicle battery voltages using diesel engines generally have 12V and 24V systems. Usually, when matching the after-treatment system, it is necessary to match the corresponding 12V after-treatment system and 24V after-treatment system. For post-processing manufacturers, at least two different post-processing system controllers need to be produced, which adds a lot of workload to product development, assembly, and controller data flashing. Contents of the invention [0003] The purpose of the present invention is to solve the problems mentioned in the background technology section above through a method for automatic identification of vehicle battery voltage. [0004] For reaching this purpose, the present invention adopts following technical scheme: [0005] A method for autom...
