PROBLEM TO BE SOLVED: To provide a vehicle appliance for reducing time since a user inputs a start operation until a function can be provided.SOLUTION: A vehicle appliance is configured so that: first control means (sub microcomputer) and second control means (main microcomputer) are in a sleep state, namely in a system sleep state, when the first control means is started, a state is transited to a standby state for waiting reception of a specific kind of data, when the specific kind of data is received in the standby state before reception standby time passes, the second control means is started so that a state is transited to a preparation state for waiting an input of a start operation in a state in which reading of a program, and expansion to a memory have been performed, and when the start operation is inputted in the preparation state before operation standby time passes, a state is transited to an execution state in which the program expanded to the memory is executed by the second control means.SELECTED DRAWING: Figure 2 |
