Embodiment 1

[0075] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0076] This embodiment provides a commercial vehicle brake disc high temperature alarm system based on the EBS system, including a signal acquisition module and a control module, the signal acquisition module includes a wheel speed sensor, a pressure sensor for monitoring the brake pressure of each wheel, and a The temperature sensor that collects the intake air temperature of the engine, and the preset brake disc temperature calculation model is embedded in the control module; the signal acquisition module transmits the collected signal to the control module, and the control module combines the collected signal data according to the preset temperature calculation model Estimate the current temperature of the brake disc.

[0077] The estimated brake disc temperature is calculated using the following two aspects, including the natural cooling proces...

Embodiment 2

[0155] The difference from Embodiment 1 is that since the friction factor μ of the friction material of the brake block changes with the temperature, the friction factor μ of each temperature range can be determined through experiments. Therefore, the friction coefficient μ of the brake pad friction material is a function of temperature.

[0156] Continuing to import the calculated friction factor μ into the formula can make the temperature calculation model more accurate.

Abstract

The invention discloses a commercial vehicle brake disc high temperature alarm system based on an EBS system. The system comprises a signal collection module and a control module, the signal collection module comprises a wheel speed sensor, a pressure sensor used for monitoring the brake pressure of each wheel, and a temperature sensor used for collecting the air inlet temperature of an engine; a preset brake disc temperature calculation model is embedded in the control module; the signal collection module transmits collected signals to the control module, and the control module calculates the current temperature of the brake disc according to a preset temperature calculation model in combination with collected signal data. Meanwhile, a high temperature alarm method based on the EPB system is designed, and a high temperature algorithm module is designed, so that the method is more accurate and more reasonable.

Description

Technical field [0001] The invention relates to the field of automobile brake temperature detection, and in particular to a commercial vehicle brake disc high temperature alarm system and method based on an EBS system. Background technique [0002] Commercial vehicles have long been a frequent source of traffic accidents. As an important part of commercial vehicle safety, the braking system plays an indispensable role. Commercial vehicles often brake for a long time after being fully loaded or overloaded, resulting in braking system failure accidents. The system of the present invention can remind the driver that the temperature of the driving disc is too high, thereby effectively avoiding the failure accident of the braking system caused by this reason. At present, traditional commercial vehicles do not have the brake disc temperature recognition function. Most situations are avoided by the driver's experience and judgment, which places high demands on the driver and makes...
