Handling rider service at autonomous vehicles

An autonomous vehicle comprising:

• one or more sensors;
• memory storing computer-executable instructions;
• and
• one or more processors coupled to the memory and configured to execute the computer-executable instructions to:
• determine that a first priority rank of a first rider service task of a task stack is higher than a second priority rank of a second rider service task of the task stack, wherein the first rider service task and the second rider service task are tasks that can be performed by the autonomous vehicle;
• determine the first rider service task from the task stack;
• determine that a fact from a fact stack at the vehicle satisfies a task condition of the first rider service task;
• and
• perform the first rider service task by changing a configuration of the autonomous vehicle.

A computer program product comprising one or more hardware storage devices having stored thereon computer-executable instructions that, when executed at a processor, cause the computer system to perform the following:

• determine that a first priority rank of a first rider service task of a task stack is higher than a second priority rank of a second rider service task of the task stack, wherein the first rider service task and the second rider service task are tasks that can be performed by the autonomous vehicle;
• determine the first rider service task from the task stack;
• determine that a fact from a fact stack at the vehicle satisfies a task condition of the first rider service task;
• and
• perform the first rider service task by changing a configuration of the autonomous vehicle.
