Abstract

Techniques are disclosed for performing hybrid simulation operations with an autonomous vehicle. A method of testing autonomous vehicle operations includes receiving, by a computer, a pre-configured scenario that includes one or more simulation parameters and one or more initial condition parameters, sending, to the autonomous vehicle and based on the one or more initial condition parameters, control signals that instruct the autonomous vehicle to operate at an operative condition, and in response to determining that the autonomous vehicle is operating at the operative condition, performing a simulation with the one or more simulated objects and the autonomous vehicle to test a response of the autonomous vehicle.

Claims (53)

1. A method of testing autonomous vehicle operation, comprising:

receiving, by a computer in an autonomous vehicle, a pre-configured scenario that includes:

a simulation parameter that indicates a presence of a simulated object in an environment that includes the autonomous vehicle, and

initial condition parameters that indicate an operative condition in which the autonomous vehicle is to be operated when a simulation is performed to test the autonomous vehicle;

sending, by the computer, control signals based on the initial condition parameters that instruct the autonomous vehicle to operate at the operative condition;

determining, by the computer, that the autonomous vehicle is operating at the operative condition;

receiving, by the computer, a status information that indicates a response of the autonomous vehicle to the simulation with the simulated object; and

comparing, by the computer, the response of the autonomous vehicle to an expected response of the autonomous vehicle.

2. The method of claim 1 , wherein the computer determines that the autonomous vehicle is operating at the operative condition by:

receiving, from the autonomous vehicle, another status information that indicates a current driving condition of the autonomous vehicle; and

determining that that the current driving condition is same as the operative condition.

3. The method of claim 1 , further comprising:

performing, based on the simulation parameter, the simulation with the simulated object and the autonomous vehicle.

4. The method of claim 1 , wherein the simulation parameter that indicates the presence of the simulated object includes positions of a simulated vehicle located and driven around the autonomous vehicle.

5. The method of claim 1 , wherein the expected response from the autonomous vehicle includes an expected performance metric or an expected output, wherein the expected performance metric comprises a range of expected response values provided by the pre-configured scenario.

6. The method of claim 1 , wherein the autonomous vehicle has passed the simulation when the response of the autonomous vehicle was a correct operation in response to a simulation performed on the autonomous vehicle, based on comparing the response of the autonomous vehicle to an expected response of the autonomous vehicle.

7. The method of claim 1 , wherein the autonomous vehicle is a semi-trailer truck comprising a cab portion and a trailer portion, further wherein the simulation parameters are designed to test the cab portion separately from the trailer portion.

8. A non-transitory computer readable program storage medium having code stored thereon, the code, when executed by a processor on an autonomous vehicle, causing the processor to implement a method comprising:

receiving a pre-configured scenario that includes:

one or more simulation parameters that indicate presence of one or more simulated objects in an environment that includes the autonomous vehicle, and

one or more initial condition parameters that indicate an operative condition in which the autonomous vehicle is to be operated when a simulation is performed to test the autonomous vehicle;

sending control signals that instruct the autonomous vehicle to operate at the operative condition;

determining that the autonomous vehicle is operating at the operative condition;

receiving, from the autonomous vehicle, a status information that indicates a response of the autonomous vehicle to the simulation with one or more simulated objects; and

comparing the response of the autonomous vehicle to an expected response of the autonomous vehicle.

9. The non-transitory computer readable program storage medium of claim 8 , wherein the autonomous vehicle is determined to operate at the operative condition by causing the processor to implement the method further comprising:

receiving, from the autonomous vehicle, another status information that indicates a current driving condition of the autonomous vehicle; and

determining that that the current driving condition is same as the operative condition.

10. The non-transitory computer readable program storage medium of claim 8 , wherein the processor is caused to implement the method further comprising:

resending the control signals to the autonomous vehicle in response to determining that the autonomous vehicle is not operating at the operative condition.

11. The non-transitory computer readable program storage medium of claim 8 , wherein the processor is caused to implement the method further comprising:

performing, based on the one or more simulation parameters, the simulation with the one or more simulated objects and the autonomous vehicle.

12. The non-transitory computer readable program storage medium of claim 8 , wherein the one or more initial condition parameters include a position, a rotation, a speed, or an acceleration of the autonomous vehicle.

13.
