<p><P>PROBLEM TO BE SOLVED: To prevent an electronic control device of a vehicle from performing malfunction by executing each of a plurality of function programs under each suitable condition in the electronic control device executing the plurality of function programs. <P>SOLUTION: In this ECU (Electronic Control Device) 10, two kinds of applications 1 and 2 are set as the function programs to be executed in a microcomputer 20 to achieve various kinds of functions for controlling the vehicle. In a memory 22, an operation power supply condition showing a power supply state from a battery 12 to each part of the vehicle is stored as an execution condition of each of the applications 1 and 2. The microcomputer 20 switches executing/stopping of each application 1 and 2 according to the operation power supply conditions stored in the memory 22 by a processing operation as a control part. When the microcomputer 20 receives a signal to start the application 2 from an other onvehicle device connected to a network, the microcomputer 20 reads the operation power supply condition of the application 2 from the memory 22, judges whether or not the operation power supply condition is established, and switches starting/stopping of the application 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
