US 2021/0200207 A1 · AUTONOMOUS VEHICLE SENSOR SECURITY SYSTEM

Abstract

Example methods and systems are disclosed to provide autonomous vehicle sensor security. An example method may include generating, by a first autonomous vehicle, a first map instance of a physical environment using first environmental information generated by a first sensor of a first autonomous vehicle. A second map instance from at least one of a second autonomous vehicle located in the physical environment is received. The first map instance may be correlated with the second map instance. In response to a discrepancy between the first map instance and the second map instance, a secure sensor may be activated to generate a third map instance. In response to the third map instance verifying that the discrepancy accurately describes the physical environment, the first environmental information including the discrepancy is used to navigate the first autonomous vehicle.

Dependent claims

A method, comprising:

comparing, by a first autonomous vehicle, first environmental information, representative of a physical environment and generated by a first sensor of the first autonomous vehicle, to second environmental information representative of the physical environment and generated by a second sensor of a second autonomous vehicle, wherein the second environmental information is concurrently generated with generation of the first environmental information;
and
in response to determining, based on the comparing, that the first environmental information comprises a discrepancy with respect to the physical environment that is not represented in the second environmental information, activating, by the first autonomous vehicle, a secure sensor of the first autonomous vehicle to generate third environmental information representative of the physical environment.

A first autonomous vehicle, comprising:

a processor;
and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
comparing first environmental information, comprising a first representation of a physical environment generated by a first sensor of the first autonomous vehicle, to second environmental information comprising a second representation of the physical environment generated by a second sensor of a second autonomous vehicle, wherein the first sensor generates the first representation concurrently with generation of the second representation by the second sensor;
and
in response to determining, based on the comparing, that the first representation indicates that an object is in the physical environment that is not represented in the second representation, activating a secure sensor of the first autonomous vehicle to generate third environmental information comprising a third representation of the physical environment.

3 more elements

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of an autonomous vehicle, facilitate performance of operations, comprising:

comparing first environmental information, indicative of a physical environment generated by a first sensor of the autonomous vehicle, to second environmental information indicative of the physical environment generated by a second sensor of roadside equipment, the first environmental information having been generated by the first sensor concurrently with the second environmental information having been generated by the second sensor;
and
in response to determining, based on a result of the comparing, that the first environmental information describes at least a portion of the physical environment differently than the second environmental information, activating a secure sensor of the autonomous vehicle to generate third environmental information of the physical environment.
