Memory readout system for vehicle control device
First Claim
1. A memory readout system comprising a vehicle control device and a readout device which is detachably connected to the vehicle control device,the vehicle control device comprising:
- a non-volatile memory that has at least a rewritable area configured to allow data writing and data deletion and an un-rewritable area configured to allow data writing and configured to inhibit data deletion;
a vehicle information write apparatus configured to generate vehicle information and to write the vehicle information into the rewritable area and into the un-rewritable area;
a vehicle information readout apparatus configured to read out the vehicle information stored in the un-rewritable area and configured to transfer the vehicle information to the readout device when the readout device is connected to the vehicle control device; and
a certification apparatus configured to perform a predetermined certification of whether or not the readout device is an authorized device or whether or not an operator using the readout device is an authorized operator,wherein the vehicle information readout apparatus is configured to read out the vehicle information stored in the un-rewritable area when the certification apparatus judges that the readout device is an authorized device or the operator using the readout device is an authorized operator,wherein the vehicle information readout apparatus is configured to read out the vehicle information stored in the rewritable area when the certification apparatus judges that the readout device is not an authorized device or that the operator using the readout device is not an authorized operator, andwherein the certification apparatus executes the certification when the vehicle control device detects an occurrence of a special condition.

Abstract
A memory readout system comprised of a vehicle control device and a readout device to be detachably connected to the vehicle control device. The readout device reads out dialogue information stored in a built-in nonvolatile memory in the vehicle control device when connected to the vehicle control device and a predetermined certification condition is satisfied. The vehicle control device is comprised of the built-in nonvolatile memory and a dialogue information readout unit. In particular, the nonvolatile memory has a un-rewritable area which allows a dialogue information writing, but inhibits a dialogue information deletion. The dialogue information readout unit reads out the dialogue information stored in the un-rewritable area when a password certification judges that the readout device is an authorized one, and then transfers the dialogue information to the readout device.
