Embodiment Construction

[0057] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0058] The brake spring of the vehicle that adopts the air-cutting kill is in the normal braking state. When the driver releases the hand brake, the brake air pressure is inflated, and the spring is pushed back after the air pressure reaches the preset value, and the parking brake system is released, so that the vehicle can drive.

Abstract

The embodiment of the application provides an inflation control method and equipment for a parking brake system. The method comprises the following steps of starting an engine to a first idle speed, and judging whether the air pressure of the parking brake system meets the starting requirement of the whole vehicle or not when the parking brake system changes from a parking state to a non-parking state; lifting the first idle speed to a second idle speed to inflate the parking brake system if the air pressure does not meet the starting requirement of the whole vehicle; and taking the air pressure of the inflated parking brake system as a new air pressure, and re-executing the step of judging whether the air pressure of the parking brake system meets the starting requirement of the whole vehicle or not. According to the method, the rotation speed of the engine is automatically increased according to the size of the air pressure, so that the rapid inflation is realized, the brake air pressure does not need to be inflated through a driver stepping on an accelerator pedal, and the automatic control of the inflation of the parking brake system is realized.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicles, and in particular to a method and device for controlling inflation of a parking brake system. Background technique [0002] With the development of the economy, the application of medium and heavy vehicles is becoming more and more extensive. Medium- and heavy-duty vehicles bear a lot of load and have high requirements for braking stability and safety. Therefore, the parking brake system of medium- and heavy-duty vehicles mostly adopts the method of cutting off air. The brake spring of the vehicle that adopts the air-cutting kill is in the normal braking state. When the driver releases the hand brake, the brake air pressure is inflated, and the spring is pushed back after the air pressure reaches the preset value, and the parking brake system is released, so that the vehicle can drive. [0003] In order to release the parking brake system of the vehicle, the driver i...
