1. An autonomous vehicle comprising:
- one or more sensors configured to obtain data regarding conditions which affect movement of the autonomous vehicle;
a speed planner coupled to the one or more sensors and configured to calculate a desired speed based, at least in part, on the data obtained from the one or more sensors;
a control system configured to calculate speed commands based, at least in part, on the speed calculated by the speed planner; and
one or more actuators configured to adjust the speed of the autonomous vehicle based on the speed commands from the control system;
wherein the speed planner is further configured to output a speed command category associated with the desired speed.

9. A method of regulating the speed of an autonomous vehicle, the method comprising:
-
receiving an input from one or more sensors regarding conditions which affect the movement of the autonomous vehicle; calculating a desired speed based, at least in part, on the received input; and outputting the desired speed to a control system configured to use the output desired speed to calculate speed commands for use by one or more actuators to adjust the speed of the autonomous vehicle; wherein outputting the desired speed includes outputting a speed command category associated with the desired speed. - View Dependent Claims (10, 11, 12, 13)

14. A program product comprising program instructions embodied on a processor-readable medium for execution by a programmable processor, wherein the program instructions are operable to cause the programmable processor to:
-
calculate a desired speed of an autonomous vehicle based on data received regarding conditions which affect movement of the autonomous vehicle and on one or more prioritized constraints; and output the calculated speed to a control system configured to use the output speed to calculate speed commands for use by one or more actuators to adjust the speed of the autonomous vehicle. - View Dependent Claims (15, 16, 17)
