[0002] Integrated Brake Control (IBC), a type of brake-by-wire technology, is a key option for electric and hybrid electric vehicles. Brake circuit leakage monitoring is crucial for vehicles with electronic power steering. Currently, IBC systems that detect abnormal brake fluid levels often employ brake assist and pedal feel degradation to alert the driver of leakage risks. However, this also increases braking risk, potentially causing fear in users who are unfamiliar with the degradation mechanism and leading to potential dangers such as insufficient braking force and inability to stop the vehicle. Summary of the Invention

[0102] The pressure sensor 313 can be installed on the side frame of the terminal 300 and / or below the touch screen display 305.

The fingerprint sensor 314 can be set on the front, back, or side of the terminal 300. If the terminal 300 is provided with a physical button or manufacturer logo, the fingerprint sensor 314 can be integrated with the physical button or manufacturer logo.

[0104] The optical sensor 315 is used to detect ambient light intensity. In one embodiment, the processor 301 can control the display brightness of the touchscreen display 305 based on the ambient light intensity detected by the optical sensor 315. Specifically, when the ambient light intensity is high, the display brightness of the touchscreen display 305 is increased; when the ambient light intensity is low, the display brightness of the touchscreen display 305 is decreased. In another embodiment, the processor 301 can also dynamically adjust the shooting parameters of the camera assembly 306 based on the ambient light intensity detected by the optical sensor 315.

[0105] Proximity sensor 316, also known as a distance sensor, is typically located on the front of terminal 300. Proximity sensor 316 is used to measure the distance between the user and the front of terminal 300. In one embodiment, when proximity sensor 316 detects that the distance between the user and the front of terminal 300 is gradually decreasing, processor 301 controls touchscreen display 305 to switch from an on-screen state to an off-screen state. When proximity sensor 316 detects that the distance between the user and the front of terminal 300 is gradually increasing, processor 301 controls touchscreen display 305 to switch from an off-screen state to an on-screen state.

The current downgrade strategy includes: The instrument lights up the brake fault light and gives a text prompt; The current maximum braking force limit is 90bar; When the brake fluid level status data is empty, the pedal feel is changed by adjusting the opening and closing of the internal pedal simulator valve; The step of obtaining the pressure-fluid volume state data in the current brake circuit and executing a strategy for determining whether a vehicle leakage actually occurs based on the data includes: Obtain the current pressure-fluid storage state data in the brake circuit; Obtaining the actual fluid storage capacity of the vehicle in the braking pressure build-up range of 10-30 bar based on the pressure-fluid storage capacity state data in the current braking circuit; Obtaining a fluid storage difference based on the actual fluid storage amount and the theoretical fluid storage amount of the vehicle in the braking pressure buildup range of 10-30 bar; Determine whether the difference in liquid storage volume is greater than a threshold value: If yes, it will downgrade to mechanical backup mode in the next ignition cycle; If not, it is considered a false alarm and the current downgrade strategy is executed until the fault is eliminated.

5. The integrated brake control assembly power degrading device according to claim 4, characterized in that: The downgrade module is further configured to: Obtain the brake fluid level status data to determine whether it is fluid level empty signal status data or sensor failure and inability to receive fluid level signal status data: If yes, it is a fault signal, go to the next step; If no, repeat the process of obtaining the brake fluid level status data.

6. A terminal, characterized in that: include: one or more processors; a memory for storing said one or more processor-executable instructions; The one or more processors are configured to: Execute the integrated brake control assembly power degrading method according to any one of claims 1 to 3.

7. A non-transitory computer-readable storage medium, characterized in that When the instructions in the storage medium are executed by the processor of the terminal, the terminal is enabled to execute the integrated brake control assembly power degrading method according to any one of claims 1 to 3.
