Embodiment 1

[0027] Please refer to figure 1 , this embodiment provides a trailer EBS braking response time simulation device, which can realize the intelligent detection of the trailer EBS braking response time, and accurately detect the trailer EBS braking response time. The trailer EBS braking response time simulation device can replace the actual main vehicle (motor vehicle) connected to the trailer, and be connected with the energy supply pipeline 9, the air pressure control pipeline connector and / or the electric control circuit 7 connector.

[0028] Generally, the main vehicle and the trailer can be connected and controlled through the electric control circuit 7, or can be connected and controlled through the air pressure control pipeline, or can be connected and controlled through the electric control circuit 7 and the air pressure control pipeline at the same time. This embodiment is described by taking the connection control between the main vehicle and the trailer through the ele...

Embodiment 2

[0059] like figure 2 As shown, the present embodiment provides a control method of a trailer EBS braking response time simulation device, using the trailer EBS braking response time simulation device of the above embodiment, the method includes:

[0060] S100: Send a braking instruction to the trailer EBS.

[0061] After the trailer EBS braking response time simulation device is connected to the trailer, power on and initialize first, establish communication between the trailer EBS braking response time simulation device and the trailer, assign an address to the trailer EBS, and communicate with each other after the address is confirmed. The trailer EBS brake response time simulation device sends a brake command EBS11 to the trailer.

[0062] After the trailer EBS receives the braking command, the trailer EBS controls the brake pedal to perform the braking action, and at the same time the trailer EBS controls the intake valve of the brake chamber to open.

[0063] It should...

Abstract

The invention provides a trailer EBS braking response time simulation device and a control method thereof, and belongs to the technical field of trailer braking. The trailer EBS braking response timesimulation device comprises a gas storage tube, a central processing unit, a controller and a collector, wherein the controller and the collector are respectively and electrically connected with the central processing unit; the central processing unit is electrically connected with a trailer EBS so as to send a braking instruction to the trailer EBS; a pressurization instruction is sent to the controller according to a feedback signal of the trailer EBS; the gas storage tube is connected with a braking gas chamber of a trailer; the controller controls the gas storage tube to perform inflationinto the braking gas chamber; the collector is arranged in the braking gas chamber of the trainer, and is used for collecting the gas pressure in the braking gas chamber; and the central processing unit calculates the braking response time of the trailer EBS according to the gas pressure collected by the collector. The simulation device can replace a main vehicle to be used for intelligently detecting the braking response time of the trailer EBS; the precise testing is realized; the portability is high; and the braking test can be performed on the trailer at any time in any place.

Description

technical field [0001] The invention relates to the technical field of trailer braking, in particular to a trailer EBS braking response time simulation device and a control method thereof. Background technique [0002] A trailer is a vehicle that is towed by a car and has no power drive itself. Combination of a vehicle (truck or tractor, forklift) and one or more trailers. Trucks and tractors are the driving sections of the car train, called the main car. The driven vehicle section towed by the main vehicle is called a trailer. Trailer is an important vehicle for road transportation, and the use of automobile and train transportation is the most effective and simple important means to improve economic benefits. It has the advantages of rapidity, maneuverability, flexibility and safety; it can conveniently realize section transportation. [0003] The length of trailer braking response time is directly related to the length of braking distance, and is an important paramete...
