摘要: A load drive circuit incorporated into an onboard electronic control device, the load drive circuit housing a diagnosis circuit for diagnosing load abnormalities, wherein diagnosis circuit failures are detected without affecting load drive control. When a failure has occurred in the diagnosis circuit, vehicle operation is not affected because the diagnosis circuit does not have a function for controlling the vehicle, and there may be cases in which occupants riding an the vehicle do not notice the failure. Additionally, when a failure has occurred in the diagnosis circuit, the occurrence of the failure cannot be detected even by a vehicle control system as long as there is no function for detecting occurrences of failure in the diagnosis circuit. Specifically, when a failure has occurred in the diagnosis circuit, there is a possibility that the failure is unrecognizable to occupants and undetectable by a vehicle control system. When there is no need for the diagnosis circuit to diagnose load abnormalities, a determination of whether or not the diagnosis circuit is failing is made by sending a pseudo abnormality signal to the diagnosis circuit and confirming whether the diagnosis circuit can detect the sent pseudo abnormality signal as a failure.

摘要: A controller for a vehicle transmission includes a storage part that stores data and a control part that executes processing by using the data stored in the storage part. The storage part stores a plurality of control processes of the vehicle transmission. The storage part further comprises a table including a start address and an end address of each of a first software program and a second software program as duplicated software programs, and the control unit executes the second software program instead of the first software program if the abnormal address is located between the first address and the end address of the first software program, and no abnormal address is located between the first address and the end address of the second software program.
