Abstract
Disclosed in some examples are methods, systems, and machine readable mediums for assessing the accuracy of one or more local sensors on a mobile device (such as an AV). In some examples, the accuracy of a local sensor of a first AV may be assessed by periodically comparing sensor readings collected by the local sensor to sensor readings matching selection criteria that are collected by one or more remote sensors located at one or more other nearby AVs. A sensor that reports data that is signifimaytly different from that reported by neighboring AVs is likely to be malfunctioning. The use of nearby sensors in nearby AVs may provide for a method for ensuring the integrity of the AV sensor readings without adding redundant sensors.
Claims25
A computing device for detecting sensor malfunctions, comprising:
- a sensor;
- a processor;
- at least one memory device, the memory device storing instructions, that when executed, cause the processor to perform operations comprising:
- determining that a reading of the sensor is to be checked;
- discovering a verification device is in a predetermined proximity to the mobile device, the verification device comprising:
- a second mobile device or an infrastructure device;
- establishing a communication session with the verification device;
- requesting a second sensor reading from the verification device;
- receiving the second sensor reading from the verification device;
- and
- determining whether the sensor on the mobile device is malfunctioning based upon a comparison between the second sensor reading from the verification device and a sensor reading from the sensor.
A method for verifying a sensor on a mobile device, the method comprising:
- determining that a reading of the sensor is to be checked;
- discovering a verification device is in a predetermined proximity to the mobile device, the verification device comprising:
- a second mobile device or an infrastructure device;
- establishing a communication session with the verification device;
- requesting a second sensor reading from the verification device;
- receiving the second sensor reading from the verification device;
- and
- determining whether the sensor on the mobile device is malfunctioning based upon a comparison between the second sensor reading from the verification device and a sensor reading from the sensor.
At least one non-transitory machine-readable medium for verifying a sensor on a mobile device, the machine-readable medium comprising operations, that when executed by a machine, causes the machine to perform operations comprising:
- determining that a reading of the sensor is to be checked;
- discovering a verification device is in a predetermined proximity to the mobile device, the verification device comprising:
- a second mobile device or an infrastructure device;
- establishing a communication session with the verification device;
- requesting a second sensor reading from the verification device;
- receiving the second sensor reading from the verification device;
- and
- determining whether the sensor on the mobile device is malfunctioning based upon a comparison between the second sensor reading from the verification device and a sensor reading from the sensor.
An apparatus for detecting sensor malfunctions, comprising:
- sensor fault checking controller logic, at least partially hardware implemented, to at least:
- determine that a reading of a sensor is to be checked;
- discover a verification device is in a predetermined proximity to the mobile device, the verification device comprising:
- a second mobile device or an infrastructure device;
- establish a communication session with the verification device;
- request a second sensor reading from the verification device;
- receive the second sensor reading from the verification device;
- and
- determine whether the sensor on the mobile device is malfunctioning based upon a comparison between the second sensor reading from the verification device and a sensor reading from the sensor.
