Problems solved by technology

[0004] However, there are disadvantages in these two methods: setting the air consumption volume of the brake chamber to the air consumption volume value corresponding to the maximum input air pressure is only applicable to the emergency braking state (the pedal stroke is the largest at this time), and is not applicable In other braking states; the air consumption volume of the brake air chamber is determined by bench testing, and it is necessary to test multiple input air pressures separately to obtain the air consumption volume value of the brake air chamber under each input air pressure. The whole process will consume more time and also increase the cost

Abstract

The invention discloses a method for determining the gas consumption volume of a brake chamber. The method comprises: receiving a gas consumption volume obtaining request; obtaining a target input gaspressure value carried by the gas consumption volume obtaining request and an identifier of a brake chamber; obtaining a pre-constructed calculation model between the gas consumption volume of the brake chamber corresponding to the identifier and the input gas pressure; and obtaining the gas consumption volume value of the brake chamber under the target input gas pressure value based on the obtained calculation model. Based on the method for determining the gas consumption volume of the brake chamber, the gas consumption volumes of the brake chambers of different specifications under different input gas pressures can be simply and quickly obtained. The invention further discloses a device for determining the gas consumption volume of the brake chamber.

Description

technical field [0001] The application belongs to the technical field of vehicle engineering, and in particular relates to a method and a device for determining the gas consumption volume of a brake chamber. Background technique [0002] The gas consumption volume of the brake chamber is a variable, which increases with the increase of the input air pressure of the brake chamber. Wherein, the input air pressure of the brake air chamber increases with the increase of the pedal stroke. The calculation of the gas consumption volume of the brake chamber is the source of the overall matching calculation of the vehicle air brake system, and its accuracy directly affects the selection and calculation of brake system components and vehicle parameters. [0003] At present, the air consumption volume of the brake chamber is usually fixedly set to the air consumption volume value corresponding to the maximum input air pressure, or the air consumption volume value corresponding to a sp...
