A vehicle-mounted device control method includes a digital certificate to perform security authentication between electronic control units (ECUs), and a function that is currently allowed to be accessed is determined based on a matching degree of certificate chains. The method comprises transmitting the digital certificate and an encrypted instruction between the ECUs, determining accessible functions based on the matching degree of certificate chains, and either starting, or failing to start, a function based on permission to access the function.
