Diagnostic arbitration system for vehicles performing multiple diagnostic tests

A diagnostic method comprising:

• determining at a plurality of diagnostic modules of a vehicle whether respective sets of conditions are satisfied for performing a plurality of diagnostic tests on circuitry of the vehicle;
• generating requests to perform a first one or more of the plurality of diagnostic tests when a corresponding one or more of the sets of conditions are satisfied for the one or more of the plurality of diagnostic tests;
• waiting for permission from an arbitration module of the vehicle to perform the first one or more of the plurality of diagnostic tests;
• and
• executing the one or more of the plurality of diagnostic tests with highest priority in response to the arbitration module providing granted permission for at least one of the one or more of the plurality of diagnostic tests and performing other ones of the one or more of the plurality of diagnostic tests subsequent to executing the at least one of the one or more of the plurality of diagnostic tests,
• wherein executing the one or more of the plurality of diagnostic tests with the highest priority includes monitoring and adjusting at least one of a voltage, a current level, a resistance, an ON and OFF state, a pressure, a temperature, and an output torque of at least one of the circuitry, a component of the circuitry, a power source of the vehicle, and a power supply system of the vehicle.

A diagnostic method comprising:

• receiving at an arbitration module of a vehicle one or more requests to perform one or more diagnostic tests on circuitry of the vehicle;
• determining priority levels of the one or more diagnostic tests;
• determining which of the one or more diagnostic tests have a highest priority level;
• and
• generating one or more responses permitting first ones of the one or more diagnostic tests with the highest priority level to be executed and one or more responses not permitting execution of second ones of the one or more diagnostic tests, wherein executing the one or more of the diagnostic tests with the highest priority level includes monitoring and adjusting at least one of a voltage, a current level, a resistance, an ON and OFF state, a pressure, a temperature, and an output torque of at least one of the circuitry, a component of the circuitry, a power source of the vehicle, and a power supply system of the vehicle.
