Controller for vehicle with self-diagnostic function and recording medium

A vehicle controller apparatus having a self-diagnostic function for automatically detecting a fault as a diagnosis object, the controller comprising:

• a self-diagnostic program to realize a self-diagnostic function, wherein the self-diagnosing program is object-oriented designed and structured in units of objects that can be reused;
• a fault detection object that is prepared for a unit in relation to the diagnosis object, to detect a fault as the diagnosis object;
• a scheduler object for determining the fault detection object as a drive object based on an external timing signal, wherein a drive of the fault detection object is instructed when the drive is permissible;
• and
• a drive determination object that determines whether the fault detection object, as a drive object determined with the scheduler object, should be driven or not, wherein a drive permission is instructed to the scheduler object, based on a determination result of the drive determination object.

A vehicle controller apparatus having a self-diagnostic function of a self-diagnostic program for automatically detecting a fault as a diagnosis object, the controller comprising:

• a fault detection object;
• a diagnosis scheduler object that executes a drive program so that the fault detection object can be determined;
• a diagnostic drive determination object for receiving the fault detection object, wherein before the fault detection object detects a fault as a diagnosis object, the diagnosis drive determination object issues an acknowledgment if it is satisfied with the drive acknowledgment request or a non-acknowledgment if the diagnosis drive determination object is unsatisfied with the drive acknowledgment request;
• and
• a memory portion for storing a fault detection result of the self-diagnostic program.

A method of operating a diagnosis scheduler object of a vehicle controller apparatus having a self-diagnostic function of a self-diagnostic program for automatically detecting a fault as a diagnosis object, the method comprising:

• executing a drive process so that a fault detection object can be determined;
• issuing and transmitting a drive acknowledgment request to a diagnosis drive determination object;
• receiving a drive acknowledgment or a drive non-acknowledgment from the diagnosis drive determination object depending on whether the diagnosis drive determination object is satisfied or unsatisfied with the drive acknowledgment request;
• receiving the drive acknowledgment or the drive non-acknowledgment from the diagnosis drive determination object;
• and
• providing a drive instruction to the fault detection object only when a drive acknowledgment is received from the diagnosis drive determination object.

A method of controlling a vehicle having a self-diagnostic function of self-diagnostic program for automatically detecting a fault as a diagnosis object, the method comprising:

• utilizing a scheduler object to determine a fault detection object as a drive object;
• determining whether the fault detection object, as a drive object determined by the scheduler object, should be driven or not utilizing a drive determination object;
• enabling the drive determination object to provide a drive permission message or a drive non-permission message to the scheduler object;
• and
• enabling the scheduler object to determine whether to send a drive instruction to the fault detection object based on whether a drive permission message or a drive non-permission message was received from the drive determination object.
