Diagnostics for smart sensors of vehicles
First Claim
1. A method, comprising:
- receiving a result of a diagnostic test for a smart sensor of a vehicle at a first time;
retrieving, from memory, a sequence indicator pertaining to a second time in which the diagnostic test is expected to be completed by the smart sensor;
providing an assessment as to whether there is a fault in the smart sensor via a processor based at least in part on the result and a comparison between the second time and the first time;
wherein the step of providing the assessment comprises;
determining that there is a fault in the smart sensor if the result is indicative of a fault in the smart sensor and the second time does not precede the first time; and
determining that there is no indication of a fault in the smart sensor if the second time precedes the first time.

Abstract
Methods, program products, and vehicles are provided for providing diagnostics for a smart sensor, such as a direct current (DC) converter, for a vehicle. A result of a diagnostic test is received from the smart sensor at a first time. A sequence indicator is retrieved from memory. The sequence indicator pertains to a second time in which the diagnostic test is expected to be completed by the smart sensor. A health assessment is provided using the result via a processor, provided that the second time does not precede the first time. The health assessments may be linked individually to a diagnostic trouble code, or may be grouped together and linked as a group to a diagnostic trouble code. Multiple smart sensor health assessments may be grouped and linked to diagnostic trouble codes.

8. A program product, comprising:
-
a program configured to at least facilitate; receiving a result of a diagnostic test for a smart sensor of a vehicle at a first time; retrieving, from memory, a sequence indicator pertaining to a second time in which the diagnostic test is expected to be completed by the smart sensor; and providing an assessment as to whether there is a fault in the smart sensor using the result and a comparison between the second time and the first time; and a non-transitory computer-readable storage medium storing the program, wherein the program is further configured to at least facilitate; determining that there is a fault in the smart sensor if the result is indicative of a fault in the smart sensor and the second time does not precede the first time; and determining that there is no indication of a fault in the smart sensor if the second time precedes the first time. - View Dependent Claims (9, 10, 11)

12. A vehicle, comprising:
-
an engine; a rechargeable energy storage system (RESS) that at least facilitates turning on the engine; a direct current (DC) converter coupled to the RESS; and a controller coupled to the DC converter, the controller comprising; a memory configured to store a sequence indicator pertaining to an execution time in which a diagnostic test is expected to be completed by the DC converter; and a processor coupled to the memory and configured to; receive a result of the diagnostic test from the DC converter at a receiving time; and provide an assessment as to whether there is a fault in the DC converter using the result and a comparison between the execution time and the receiving time, wherein the processor is configured to at least facilitate; determining that there is a fault in the smart sensor if the result is indicative of a fault in the smart sensor and the execution time precedes the receiving time; and determining that there is no indication of a fault in the smart sensor if the receiving time precedes the execution time. - View Dependent Claims (13, 14, 15, 16, 17)
