Cabin area controller, automobile and memory operation method

The invention relates to a cockpit domain controller, an automobile and a memory operation method, and relates to the field of storage, and the method comprises the following steps: monitoring an I/O operation of an application on a built-in memory after the cockpit domain controller is powered on and started; if it is monitored that the application performs the I/O operation on the built-in memory, determining a data type of application data corresponding to the I/O operation; and if the data type of the application data is the preset data type, modifying a read-write parameter corresponding to the preset data type in a memory so as to reduce the number of I/O operations. According to the embodiment of the invention, when the application performs the I/O operation on the built-in memory, the corresponding read-write parameters in the memory can be modified when the application data type is the preset data type, so that the I/O operation frequency is reduced, and the service life of the built-in memory is pro
