It should be understood that the following drawings only show certain embodiments of the present application and therefore should not be regarded as limiting the scope.

[0026] First, the common application of the present application is described. The technical solution of the present application can be applied to the design and implementation of a vehicle terminal system for early warning through the vehicle's ambient light.

[0027] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0028] In one embodiment of the present application, a plurality of different warning tasks are configured for the vehicle, and each warning task is configured with a corresponding priority, as well as corresponding warning conditions and ambient light control schemes.

[0029] For example, the warning task may be DOW_ACTION (door opening warning). When a dangerous target (sedan, truck, two-wheeled vehicle, pedestrian) is detected approaching the left or right door of the vehicle quickly, the door opening warning is triggered, and the left or right ambient light of the vehicle flashes red. After the alarm is lifted, the ambient light status returns to the state before the alarm.

[0030] The warning task can also be RCTA_ACTION (parking exit warning). When the vehicle is detected to be in R gear and a dangerous object is approaching rapidly from the rear, the left and / or right ambient lights of the vehicle flash red. After the alarm is lifted, the ambient light status returns to the status before the alarm.

[0031] The warning task can also be MIK_ACTION (fatigue distraction warning). When the user is judged to be severely fatigued or distracted, the color of all ambient lights changes from the user-set color to red and the brightness is adjusted from 10% to 100%, flashing for 15 seconds at a frequency of 200ms.

[0032] The warning task can also be SPEEDING_ACTION (speeding warning). When the vehicle is detected to be speeding, the color of the ambient light changes from the user-set color to red and the brightness is 100%. The ambient light state is restored after the speeding warning is lifted.

[0033] In order to manage multiple warning tasks of a vehicle, this application proposes a polling method to implement the execution of the warning tasks.

[0034] Figure 1 A flowchart of a polling step provided in an embodiment of the present application. Figure 1 As shown, in this embodiment, the polling step can be performed by the micro control unit of the vehicle. Specifically, the micro control unit of the vehicle can respond to the power-on signal of the vehicle and perform the following polling steps according to a preset frequency:

[0035] S1. Determine a current warning task list, where the warning task list includes a plurality of warning tasks arranged according to priority.

[0036] Specifically, the current warning task list can be determined in the following ways:

[0037] Determine all current warning tasks. Arrange all warning tasks according to the priority of each warning task to generate a warning task list. Each warning task is associated with a corresponding warning condition and atmosphere light control scheme.

[0038] This is because the warning tasks can be added or deleted according to the needs or user configuration. Therefore, at the beginning of each polling, a new warning task list is generated. All the currently effective warning tasks can be obtained at the specified address and arranged from high to low according to the priority. It should be noted that the priorities of multiple warning tasks are different.

[0039] S2. Determine the target warning task with the highest priority among the warning tasks that have not been detected in the warning task list, and the warning conditions corresponding to the target warning task.

[0040] Starting from the target warning task with the highest current priority in the warning task list, determine whether the warning conditions of the target warning task are met.

[0041] S3. Based on the vehicle's operating data, determine whether the warning conditions corresponding to the target warning task are met.

[0042] In step S3, the micro control unit of the vehicle may obtain the operating data of the vehicle and determine the vehicle status to determine whether the warning condition corresponding to the target warning task is met.

[0043] Specifically, in one case, the micro control unit of the vehicle can directly obtain signals from corresponding components of the vehicle for determining early warning conditions.

[0044] For example, if the warning task is a door opening warning, the steps of determining whether the warning conditions corresponding to the target warning task are met based on the vehicle's operating data include:

[0045] The door status signal is obtained through the CAN bus. According to the door status signal, it is determined whether the door is open. If so, it is determined whether there is a dangerous target approaching the door. If so, it is determined that the warning condition is met. If not, the warning condition is not met.

[0046] The vehicle's microcontroller unit can directly obtain the door status signal of each door through the CAN bus. The door status signal here is used to indicate the open or closed state of the corresponding door.

[0047] When it is determined that the left and / or right door is open, it is determined whether a dangerous target is approaching the corresponding door. Here, an image sensor or a radar sensor on the vehicle can be used, for example, to obtain an image near the door captured by the image sensor to identify whether there is a dangerous target in the image. If so, it can be determined that the warning condition is met.

[0048] In another case, the vehicle's microcontroller unit can obtain operating data from the vehicle's system-on-chip (Soc).

[0049] For example, if the warning task is fatigue driving warning, the steps of determining whether the warning conditions corresponding to the target warning task are met based on the vehicle's operating data include:

[0050] Obtain the driver's driving status sent by the system-level chip through SPI. Determine whether the driver's driving status is fatigue driving. If so, determine that the warning condition is met. If not, the warning condition is not met.

[0051] The system-level chip here can collect the driver's facial image through the image sensor on the vehicle and identify the driver's driving status through the facial image.

[0052] S4. If the conditions are met, determine the ambient light control scheme corresponding to the target warning task to control the ambient light of the vehicle to issue a warning, and exit the current polling.

[0053] In step S4, when the target warning task meets the warning condition, the current polling is exited, and the warning task of the next priority is no longer retrieved and judged. In this way, redundant warning triggering can be avoided, and only the most serious warning is reminded.

[0054] If not satisfied, return to the step of determining the target warning task.

[0055] If the target warning task with the highest current priority among the warning tasks that have not been detected does not meet the warning conditions, the next warning task will be judged in a loop and continued to be executed in the order of priority 1, priority 2, priority 3, ..., priority N until all warning tasks in the warning task list have been cycled through, then the cycle ends.

[0056] After one polling is completed, the micro control unit can perform the next polling according to the preset frequency.

[0057] In this way, all warning tasks can be managed and scheduled as a whole. When project requirements change, adding or deleting warning tasks, modifying warning task priorities, or modifying warning conditions and ambient light execution actions are very flexible. The system only needs to configure the data structure corresponding to the warning task without changing the code logic of the polling steps, which enhances the flexibility of warning scheme configuration and has strong scalability. In addition, the Base code of different projects can be transferred and modified, which improves code reusability and reduces the work of programmers.

[0058] At the same time, in the technical solution of the present application, a warning function of different atmosphere lights is also provided for possible dangers that may arise during the use of the vehicle, which can further ensure the safety of vehicle driving.

[0062] Based on the vehicle's operating data, determine whether the warning conditions corresponding to the target warning task are met;

[0063] If the conditions are met, the ambient light control scheme corresponding to the target warning task is determined to control the ambient light action of the vehicle to issue a warning, and the current polling is exited;
