Description

Vehicle control method, apparatus, vehicle, and storage medium Technical Field The present application relates to the field of vehicle control technologies, and in particular, to a vehicle control method, device, vehicle, and storage medium. Background With the continuous improvement of vehicle intellectualization and safety standards, riding safety of children and passengers is increasingly emphasized. In order to effectively prevent a child from unlocking a vehicle door due to false touch or false operation in the running or temporary parking process of the vehicle, the prior art scheme generally relies on a child safety lock function, and locks an internal unlocking device of a rear vehicle door in a physical or electric control mode. Therefore, ensuring that the child safety lock can be reliably and timely activated when necessary is one of the key links for improving the passive safety of children. However, related art child safety locks for vehicles are mainly classified into mechanical type and electric type. The mechanical safety lock is usually switched manually on the rear door side by using a key or a special tool, and the electric control type safety lock can be manually started or stopped by a driver through a physical or touch button of the center console. The common limitation of both types of solutions is that whether the function is activated or not is entirely dependent on the active recognition, memory and manual operation of the driver. In an actual vehicle scenario, the driver may be inattentive, forgotten, or not timely aware when temporarily carrying the child, resulting in the child safety lock not being activated, leaving behind a safety hazard. Disclosure of Invention In view of the foregoing, the present application is directed to a vehicle control method, apparatus, vehicle, and storage medium capable of automatically triggering a child protection operation, enhancing the safety protection of rear children of the vehicle. According to a first aspect of the embodiment of the application, a vehicle control method is provided, which comprises the steps of obtaining perception data of at least two data channels of a rear row of a target vehicle, determining a channel score value corresponding to each data channel based on the perception data of each data channel, wherein the channel score value is used for representing the probability of children in the rear row of the target vehicle and is related to a rear passenger type represented by the corresponding perception data, the channel score value corresponding to the rear passenger type comprises children and is higher than the channel score value corresponding to the rear passenger type only comprises adults, the channel score value corresponding to the rear passenger type only comprises adults and is higher than the channel score value corresponding to the rear passenger type as no person, determining a target score according to the channel score values of the at least two data channels, and generating a control instruction for controlling the target vehicle to execute a child protection operation under the condition that the target score exceeds a preset threshold. The traditional scheme adopts a binary classification mode to directly judge whether children exist or not, and when the sensor misjudges at the boundary of the children and the adults, the final judgment is directly wrong. According to the application, the intermediate scoring of the adult is introduced, so that when a certain channel misjudges the child as the adult, the output intermediate scoring of the adult is still higher than that of the unmanned state, and the correct scoring of other channels can compensate the deviation. Also, when an adult is misjudged as a child, its score is still lower than that of a real child. Therefore, the target score after multi-channel fusion can reflect the actual situation more accurately, the problem of misjudgment of the traditional scheme at the recognition boundary is effectively solved, and the accuracy and reliability of triggering of protection functions such as the child safety lock are remarkably improved. Optionally, the generating the control instruction for controlling the target vehicle to execute the child protection operation comprises generating the control instruction for controlling the child safety lock of the target vehicle according to the monitoring result of the driver and the passenger of the target vehicle. The target vehicle driver and passenger are monitored, the monitoring result is obtained, and a control instruction for controlling the target vehicle child safety lock is generated based on the monitoring result, so that the targeted control of the child safety lock is realized. The scheme combines the actual state of the driver and the passenger to adjust the opening and closing of the child safety lock, avoids the inconvenience and potential safety hazard caused by the fixed opening or closing of the
