Overheat alarm device for vehicle disc and control method thereof

Abstract

The invention relates to a vehicle disc overheat-warning system and a control method thereof. According to the operating states of a braking safety system and a brake system mounted on a vehicle, the vehicle disc overheat-warning system predicts the temperature of discs by increasing and decreasing the heat generated by the braking safety system and the brake system in operation and the coolness of the braking safety system and the brake system not in operation, and thereby not only can warn the overheating state of the discs, but also can prevent misoperation by stopping the operation of the braking safety system, so that the vehicle can be safely driven.

Description

technical field [0001] The present invention relates to an overheating alarm device for a disc of a vehicle and a control method thereof, more specifically, to predicting the temperature of the disc according to the brake safety system installed in the vehicle and the working state of the brake system, so as to warn the overheating state of the disc, and An overheating warning device for a disc of a vehicle limiting the operation of a brake safety system and a method thereof. Background technique [0002] Generally, the brake system is an important device used to slow down or stop a running car while maintaining a parked state. It mainly uses a friction brake, which uses friction to convert the kinetic energy of the car into heat energy and discharges the heat energy to the In the atmosphere, so as to play a role in production. [0003] That is, the brake system of a car is a system in which friction material is attached to brake drums or discs, etc., and the friction force...

Problems solved by technology

As a result, the resin used as the adhesive of the gasket is vaporized to generate air bubbles, and the vaporized air bubbles adhere to the surface of the disc to form a gas coating layer, and this gas coating layer acts as a lubricant. To hinder the friction between the disc and the gasket, causing a temporary loss of braking force (fade) phenomenon

[0008] The fading phenomenon described above may also be caused by the disc becoming overheated when the brake is applied for a specified time or longer when the ABS is operating, or when excessive brake pressure is applied. It may also occur when driving on an asymmetric road In TCS, as the disc becomes overheated due to the brake pressure on the low-friction road surface, not only the performance of the brake safety system is degraded, but also the normal control may not be achieved.

[0009] However, since the driver cannot know the state of the fading phenomenon caused by the overheating of the disc as described above, there is a possibility of causing a dangerous situation when only the brake safety system works and travels.
