Abstract
In one aspect, an integrated circuit (IC) includes a sensor. The sensor includes a processor configured to provide speed and/or direction of a target object based on the speed of the target object; monitor for a diagnostic fault; provide information if the diagnostic fault is detected; monitor for critical faults; and provide information if a critical fault is detected and the sensor recovers from the critical fault.
Claims33
An integrated circuit (IC) comprising:
- a sensor comprising a processor configured to:
- provide speed information of a target object in response to a speed of the target object being greater than a first predetermined value;
- provide the speed information and direction information of the target object in response to the speed being below the first predetermined value;
- monitor for a diagnostic fault;
- provide a diagnostic flag and information bits in response to the diagnostic fault being detected;
- monitor for a critical fault;
- and
- provide the information bits in response to the critical fault being detected and in response to the sensor recovering from the critical fault,
- wherein the processor configured to provide the diagnostic flag and the information bits in response to the diagnostic fault being detected comprises the processor configured to finish providing the speed information before providing the diagnostic flag and the information bits in response to the diagnostic fault occurring during transmission of the speed information.
