Vehicle diagnosis apparatus and method thereof

A method of inspecting a host vehicle, the method comprising:

• storing failure diagnosis model information for each of a group of vehicle parts in a memory, wherein the failure diagnosis model information is obtained while a test vehicle equipped with each of the group of the vehicle parts in a failure state is driving on a test road at a variety of different test driving conditions of the test vehicle and test road surface conditions of the test road;
• generating information on host-vehicle driving conditions of the host vehicle and current road surface conditions of a current road on which the host vehicle is currently traveling;
• determining whether the test driving conditions and the test road surface conditions of the test road stored in the memory and the host-vehicle driving conditions and the current road surface conditions for the host vehicle are consistent with each other;
• comparing sensor information generated by a sensor with the failure diagnosis model information and determining whether a given vehicle part of the group of the vehicle parts has failed based on the host-vehicle driving conditions and the current road surface conditions for the host vehicle and the test driving conditions and the test road surface conditions being consistent with each other;
• and
• alerting a driver of the host vehicle that the given vehicle part has failed.

A method of inspecting a host vehicle, the method comprising:

• sensing host-vehicle status information, host-vehicle driving conditions, and current road surface conditions on a current road on which the host vehicle is traveling, wherein the host-vehicle status information includes a first measurement of a current condition of a first vehicle part of the host vehicle;
• comparing the host-vehicle driving conditions and the current road surface conditions of the current road with test-vehicle driving conditions and tested road surface conditions, wherein the test-vehicle driving conditions and the tested road surface conditions were previously measured on a test road and previously stored in a memory, and wherein the test-vehicle driving conditions and the tested road surface conditions are a first portion of failure diagnosis model information stored in the memory;
• based on the host-vehicle driving conditions and the current road surface conditions of the current road being consistent with the test-vehicle driving conditions and the tested road surface conditions measured on the test road, comparing the first measurement with previously measured failure data corresponding to the first vehicle part being in a failed state, to determine whether the first vehicle part is in the failed state;
• and
• based on determining that the first vehicle part is in the failed state, generating a first alert corresponding to the first vehicle part.
