Benefits of technology

The present invention allows for continuous usage of vehicles' own car air conditioner (CAC) without causing excessive temperatures that could harm their performance or cause damage during prolonged periods. This helps maintain better coolant system function while reducing energy consumption compared with traditional methods like refrigerators.

Problems solved by technology

This technical problem addressed in this patented technology relates to improving the durability or effectiveness of an anti-lock brakes (ABS) system during prolonged periods of heavy usage under different types of weather conditions such as rainwater snowfall.

Embodiment 1

[0022] An embodiment of the invention provides a control system for a vehicle brake.

[0023] figure 1 is a block diagram of a vehicle brake control system according to an embodiment of the present invention. Such as figure 1 As shown, the system includes: a temperature sensor 10 , an auxiliary brake 20 and a brake controller 30 .

[0024] Wherein, the temperature sensor 10 is used to detect the actual temperature value of the service brake.

[0025] Auxiliary brake 20, the auxiliary brake 20 is used to provide braking force.

[0026] The brake controller 30, the brake controller 30 respectively establishes a communication connection with the temperature sensor 10 and the auxiliary brake 20 for collecting and processing the actual temperature value of the service brake, and using the actual temperature value as a parameter to determine the predicted temperature through the temperature prediction model value, and judge whether to activate the auxiliary brake 20 according to...

Embodiment 2

[0047] An embodiment of the present invention provides a control method for a vehicle brake.

[0048] Figure 5 is a flowchart of a method for controlling a brake of a vehicle according to an embodiment of the present invention. Such as Figure 5 As shown, the method includes the following steps:

[0049] Step S11, reading a preset first time interval.

[0050] Specifically, through the above step S11, the preset first time interval is obtained, and the actual temperature of the service brake is obtained according to the first time interval.

[0051] Step S13, acquiring actual temperature values ​​of the service brake collected within a predetermined time range according to the first time interval, and generating a first actual temperature sequence.

[0052] Specifically, through the above step S13, according to the obtained first time interval, the actual temperature value of the service brake is acquired at a fixed frequency, and the first actual temperature sequence is ...

Abstract

The invention discloses a control method and system of vehicle brakes. The method includes: reading a preset first time interval; acquiring the actual temperature value, collected in a preset time range, of a service brake according to the first time interval, and generating a first actual temperature sequence; inputting the first actual temperature sequence into a temperature prediction model so as to predict the prediction temperature value of the service brake at the next collecting moment; judging whether the prediction temperature value is larger than a preset first temperature threshold or not; if so starting an auxiliary brake. By the method, the problems that a vehicle continuously use the brakes, the temperature of the brakes is excessively high, the brake efficiency of the service brake is lowered, and vehicle travelling safety is affected in the prior art are solved.
