Specifically, the location acquisition mode of the user terminal includes a mode of positioning through satellite positioning, wireless fidelity (Wireless Fidelity, wi-Fi) and base station positioning. For example, in the case where the vehicle parking position is an outdoor parking lot, the position information of the target user is acquired by using satellite positioning because the accuracy of the position information acquired by using satellite positioning is high; if the satellite signals of the parking positions of the vehicles are weak, such as an underground parking lot, the positions of the users are usually indoor environments, and if a plurality of Wi-Fi signals are detected, the Wi-Fi positioning mode is adopted to acquire the position information of the target users.
The get-on intention refers to determining that the target user has a get-on intention through the position information, for example, detecting that the position information of the user is a parking lot where the vehicle is parked, and then determining that the target user has a get-on intention.

The embodiment is not limited in this regard, so as to prompt the target user that the vehicle key is not carried.
Under the condition that the target user has the boarding intention, if the target user is found to not carry the vehicle key, the first prompt information is sent to the user terminal of the target user to prompt the target user not to carry the vehicle key, so that the situation that the user cannot unlock the vehicle because the user does not carry the vehicle key is avoided.
Step 103, receiving a digital key generation instruction sent by the target user based on the prompt information.
