Layered architecture for availability of advanced driver assistance features

A system for controlling availability of autonomy functions of a vehicle, the system comprising:

• a processor;
• and
• memory storing instructions that, when executed by the processor cause the processor to perform the steps of:
• determining one or more uncertainty levels, each corresponding to a driving data stream comprising driving data, wherein the uncertainty levels correspond to a probability of an undesirable outcome;
• generating a total uncertainty level based on the one or more uncertainty levels;
• disabling a driver assistance feature comprising an adaptive cruise control that includes a plurality of autonomy functions including a first autonomy function based on availability criteria of the first autonomy function, the plurality of autonomy functions further including a second autonomy function;
• and
• enabling a second driver assistance feature when the first autonomy function and the second autonomy function of the driver assistance feature are disabled based on a first uncertainty level for the first autonomy function and a second uncertainty level for the second autonomy function,
• wherein the first uncertainty level includes its own respective threshold that is triggered and the second uncertainty level includes its own respective threshold is triggered, the first uncertainty level and the second uncertainty level being defined in a respective availability criteria, and the first uncertainty level corresponding to a first driving data stream and the second uncertainty level corresponding to a second driving data stream,
• wherein the availability criteria define a first threshold of the total uncertainty level,
• wherein the first autonomy function remains enabled when the second autonomy function is disabled, and
• wherein the first autonomy function includes a lane keeping autonomous function, the second autonomy function includes a following distance autonomy function, and the second driver assistance feature comprises basic cruise control.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for controlling availability of autonomy functions of a vehicle, the method comprising:

• determining one or more uncertainty levels, each corresponding to a driving data stream comprising driving data, wherein the uncertainty levels correspond to a probability of an undesirable outcome;
• generating a total uncertainty level based on the one or more uncertainty levels;
• disabling a driver assistance feature comprising an adaptive cruise control that includes a plurality of autonomy functions including a first autonomy function based on availability criteria of the first autonomy function, the plurality of autonomy functions further including a second autonomy function;
• and
• enabling a second driver assistance feature when the first autonomy function and the second autonomy function of the driver assistance feature are disabled based on a first uncertainty level for the first autonomy function and a second uncertainty level for the second autonomy function,
• wherein the first uncertainty level includes its own respective threshold that is triggered and the second uncertainty level includes its own respective threshold is triggered, the first uncertainty level and the second uncertainty level being defined in a respective availability criteria, and the first uncertainty level corresponding to a first driving data stream and the second uncertainty level corresponding to a second driving data stream,
• wherein the availability criteria define a first threshold of the total uncertainty level,
• wherein the first autonomy function remains enabled when the second autonomy function is disabled, and
• wherein the first autonomy function includes a lane keeping autonomous function, the second autonomy function includes a following distance autonomy function, and the second driver assistance feature comprises basic cruise control.
