Description

This application claims priority to Chinese Patent Application No. 2023117101352, filed with the China National Intellectual Property Administration on December 12, 2023 and entitled "CAR CRASH DETECTION METHOD, APPARATUS, AND SYSTEM, TERMINAL DEVICE, AND VEHICLE-MOUNTED DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD This application relates to the field of safe traveling technologies, and in particular, to a car crash detection method, apparatus, and system, a terminal device, and a vehicle-mounted device. BACKGROUND Vehicle accidents are one of the leading causes of death worldwide, and a survival rate depends to a large extent on an arrival speed of rescue personnel after an accident happens. With development of terminal technologies, usage of mobile terminals is increasingly high, and currently, some terminal devices provide a car crash detection function. After detecting a severe car crash, the terminal device automatically makes a call for emergency help and calls an emergency contact of a user, thereby seeking help quickly. However, the current car crash detection function of the terminal device generally identifies and detects a car crash based on a sensor on the terminal device. A limitation of performance of the sensor limits a capability of the device to identify and detect a car crash, and a car crash that happens may not be detected. In addition, when the user carries the terminal device while participating in an activity like skiing or riding a roller coaster, the terminal device may give a false car crash alarm, that is, a state of the user in a special scenario is identified as a car crash. Therefore, how to improve accuracy of car crash detection while ensuring a timely call for rescue becomes an urgent technical problem to be resolved. SUMMARY This application provides a car crash detection method, apparatus, and system, a terminal device, and a vehicle-mounted device, to implement car crash detection through interaction between the terminal device and the vehicle-mounted device. When it is determined that a car crash is detected, the terminal device makes a call for emergency rescue, to improve accuracy of car crash detection while ensuring a timely call, thereby reducing or even avoiding false alarms of car crash detection. According to a first aspect, a car crash detection method is provided. The method is applied to a terminal device. The method includes: detecting first traveling data of a vehicle; receiving first abnormality prompt information sent by a vehicle-mounted device; and determining, based on the first traveling data and the first abnormality prompt information, whether to make a call for emergency rescue, where the vehicle-mounted device and the terminal device are in the vehicle, and there is a communication connection between the vehicle-mounted device and the terminal device. In the car crash detection method according to the first aspect, when whether to make a call for emergency rescue is being determined, information from both the terminal device and the vehicle-mounted device that are in the same vehicle needs to be considered, that is, during car crash detection, traveling abnormality detection by the vehicle-mounted device and the terminal device is fully considered. Therefore, vehicle status detection by the vehicle-mounted device may be combined with car crash detection and emergency rescue calling capabilities of the terminal device, thereby improving car crash detection accuracy. In addition, when a user carries the terminal device while participating in an activity like skiing or riding a roller coaster, because the prerequisite condition that the terminal device and the vehicle-mounted device are in the same vehicle is not met, the terminal device does not make a call for emergency rescue during skiing and roller coaster riding. Therefore, the car crash detection method according to the first aspect can further avoid false car crash alarms in special cases such as skiing and roller coaster riding. In a possible implementation of the first aspect, the first abnormality prompt information includes indication information, the indication information indicates that the vehicle has a traveling abnormality, and determining, based on the first traveling data and the first abnormality prompt information, whether to make a call for emergency rescue includes: determining, based on the indication information and the first traveling data, whether the vehicle actually has a traveling abnormality; and determining, based on whether the vehicle actually has a traveling abnormality, whether to make a call for emergency rescue. In this implementation, after receiving the indication information sent by the vehicle-mounted device to indicate that the vehicle has a traveling abnormality, second detection is performed based on the indication information and the first traveling data, to determine whether there is actually a traveling abnormality
