ELECTRONIC CONTROL APPARATUS AND VEHICLE CONTROL SYSTEM
First Claim
1. An electronic control apparatus for a vehicle comprising:
- an identification information memory device for storing vehicle identification information uniquely assigned to the vehicle;
an individual information memory device for storing vehicle individual information related to the vehicle;
a memory control device for causing the vehicle identification information to be overwritten in response to an overwrite command;
a clear device for clearing the vehicle individual information from the individual information memory device when the vehicle identification information is overwritten;
an equality determination device for determining whether old vehicle identification information is equal to new vehicle identification information for overwriting the old vehicle identification information, the old vehicle identification information being previously written to the identification information memory device and currently stored in the identification information memory device; and
a clear control device for performing a clear control, the clear control enabling the clear device to clear the vehicle individual information upon determination of the equality determination device that the old vehicle identification information is different than the new vehicle identification information, the clear control disabling the clear device from clearing the vehicle individual information upon determination of the equality determination device that the old vehicle identification information is equal to the new vehicle identification information.

Abstract
A vehicle electronic control apparatus stores vehicle identification information uniquely assigned to a vehicle and vehicle individual information related to the vehicle. When the vehicle identification information is overwritten with new vehicle identification information, it is determined whether the vehicle identification information is equal to the new vehicle identification information. If it is determined that the vehicle identification information is different than the new vehicle identification information, the vehicle individual information is cleared at a time when the vehicle identification information is overwritten with new vehicle identification information. If it is determined that the vehicle identification information is equal to the new vehicle identification information, the vehicle individual information is not cleared at the time when the vehicle identification information is overwritten with new vehicle identification information.
