Abstract
In a vehicle built-in electronic control apparatus, second control programs are written, second RAM memory for calculation processing and second input/output ports, and a serial-parallel converter for full duplex two-way serial communication for mutually conducting data communications between the main CPU and the sub CPU in operation of the controlled vehicle, and at the time of starting operation of the controlled vehicle, a part of the control constants stored in the first nonvolatile memory is transferred to the second RAM memory through the serial-parallel converter for the serial communication and the sub CPU performs predetermined calculation based on the contents of the second control programs of the second nonvolatile memory and the contents of the control constants transferred to the second RAM memory.
