ELECTRONIC CONTROL APPARATUS FOR ELECTRICALLY-DRIVEN VEHICLE
First Claim
1. An electronic control apparatus for controlling an electrically-driven vehicle, which has, as a drive power source for vehicle travel, a motor supplied with electric power from an electric power supply source without an engine, and having a self-diagnosis function for storing an abnormality code corresponding to a diagnosis object when abnormality of the diagnosis object is detected, the electronic control apparatus comprising:
- a memory for storing the abnormality code indicative of the abnormality of the diagnosis object;
an operation check part for checking whether the motor and the electric power supply source are operating normally when a power control switch is turned on to supply electric power from the electric power supply source under a state that the abnormality code is stored in the memory;
an abnormality check part for checking whether abnormality is detected again in the diagnosis object, the abnormality code of which has already been stored in the memory, when the operation check part determines that both the motor and the electric power supply source are operating normally; and
an erasure part for erasing the abnormality code stored in the memory when the abnormality check part determines that no abnormality is detected again.

Abstract
An electronic control apparatus controls am electrically-driven vehicle, which has no engine but has only a motor supplied with electric power from an electric power supply source. The electronic control apparatus has a self-diagnosis function for storing an abnormality code corresponding to a diagnosis object when abnormality of the diagnosis object is detected. The electronic control apparatus checks whether the motor and the electric power supply source are operating normally when a power control switch is turned on under a state that the abnormality code is stored in a memory. The electronic control apparatus checks whether abnormality is detected again in the diagnosis object, the abnormality code of which has already been stored, when the motor and the electric power supply source are operating normally. The electronic control unit erases the abnormality code when no abnormality is detected again.
