[0086] Example 4:

[0087] In view of the increasing necessity of installing disc brakes, but the high temperature of the brake disc leads to brake system problems, which in turn leads to a high proportion of traffic accidents, so it is necessary to monitor and effectively reduce the temperature of the brake disc. The existing method is only a single direct water spraying method for the brake, which is easy to cause the brake disc to burst, and wastes water and affects the road, such as Figure 7 As shown, the present application provides a disc brake intelligent temperature control method, comprising the following steps:

[0088] S1. The whole vehicle runs, and the main control device collects the temperature values of each disc brake through the temperature monitoring device; The specific steps of step S1 are as follows:

[0089] S11. After the automobile starts, the whole vehicle runs;

[0090] S12. The automobile electronic control unit ECU obtains the temperature value of the temperature sensor arranged at each disc brake, and obtains the temperature value of each disc brake;

[0092] S21. The spray volume of the atomizing spray cooling device is divided into levels in advance, and a spray temperature threshold is set for each level of spray volume;

[0093] For example, the spray volume of the atomizing spray cooling device is pre-divided into four levels, with level four being the maximum; the spray temperature threshold corresponding to level one is set to 100℃, level two to 200℃, level three to 300℃, and level four to 450℃.

[0098] S24. The vehicle's electronic control unit (ECU) activates the atomizing spray cooling device and controls the atomizing spray cooling device to spray and cool the disc brakes according to the target spray setting via a solenoid valve.

[0099] For example, when the disc brake temperature is 100℃, the vehicle's electronic control unit (ECU) activates a yellow warning light in the driver's cab to indicate a risk of overheating. Simultaneously, the ECU automatically opens the solenoid valves at the air reservoir and water outlet, activating the first setting of the atomizing spray cooling device to cool the brake disc.

When the disc brake temperature reaches 450℃, the ECU activates the fourth setting of the atomizing spray cooling device to begin cooling, and simultaneously activates a red warning light in the driver's cab to indicate that the brake disc temperature is too high and request the driver to stop and check.

The main control device determines whether the temperature value of each disc brake exceeds the pressure regulating temperature threshold, and when it does, controls the air pressure regulating device to adjust the pressure of the corresponding wheel end brake pipe to reduce the heat generation of the corresponding disc brake; the specific steps of step S3 are as follows:

[0103] S31. The automobile electronic control unit ECU determines whether the disc brake temperature exceeds the pressure regulating temperature threshold;

[0104] If yes, go to step S32;

[0105] If no, return to step S1;

[0106] S32. The automobile electronic control unit ECU determines the pipe pressure distribution strategy according to the disc brake temperature and provides it to the automobile anti-lock braking system EBS;

[0107] S33. The automobile anti-lock braking system EBS adjusts the pressure of each wheel end brake pipe according to the pipe pressure distribution strategy to reduce the heat generation of the corresponding disc brake;

[0108] The wear information of each wheel end is detected and transmitted to the automobile electronic control unit ECU, which transmits the relevant data to the automobile anti-lock braking system EBS, thereby monitoring the temperature value of each wheel end. When the temperature difference exceeds the set value, the real-time monitoring and regulation of the brake friction pair temperature of the whole vehicle is realized by adjusting the pressure of each wheel end brake pipe.
