This application relates to the field of digital key technology, and particularly to a perception method, device, vehicle, and storage medium for dual driving scenarios. The method includes: generating key information based on terminal instructions from corresponding terminals in different scenarios and synchronizing it to the vehicle; determining a broadcast mode based on the terminal and the current scenario, and controlling the vehicle to parse the key information based on the broadcast mode to obtain a key verification result; determining the actual distance between the terminal and the vehicle based on the received signal strength indication when the key verification result is successful; and generating control instructions for the vehicle based on the terminal, the broadcast mode, and the actual distance.
