OPEN PLATFORM BASED SECURE VEHICLE CONTROL METHOD

This application discloses a vehicle and a vehicle security control method and system based on an open platform. The open platform includes a software development kit in which a control protocol is encapsulated, the software development kit provides an API function interface, and the method includes the following steps: receiving a call request from a third-party device for a target API function interface of the open platform; converting the call request by using the software development kit to generate a control signal that meets a requirement of the control protocol and that is used for controlling a first vehicle component in a vehicle; and transmitting the control signal to a security gateway through a first bus, to enable the security gateway to perform protocol conversion on the control signal, and transmitting the control signal to an in-vehicle network to control the first vehicle component in the vehicle.
