Detection of false vehicle-to-vehicle emergency brake light messages
First Claim
1. An apparatus comprising:
- a wireless receiver configured to receive a signal from a vehicle, wherein the signal comprises a message representative of a relative safety condition between the vehicle and the apparatus; and
message trustworthiness logic operatively coupled with the wireless receiver and operable to measure a power of the signal, the message trustworthiness logic determining a trustworthiness level of the message in accordance with a statistical modeling of the power of the signal over an interval of time, andthe message trustworthiness logic selectively generating a safety alert signal responsive to the trustworthiness level of the message.

Abstract
The trustworthiness of vehicle-to-vehicle (V2V) messages received from one or more associated vehicles in the vicinity of a subject vehicle is determined autonomously by a false signal detection system of the subject vehicle. Physical evidence relating to the associated vehicles is collected, and a statistical model is used to perform an analysis of the collected data. A V2V message is received by the system from a first one of the associated vehicles and a trustworthiness level of the message is determined in accordance with a correlation between the received V2V message and the result of the analyzed physical data relating to the first associated vehicle. The correlation may be a comparison of data contained in the received V2V message relative to a result of a stochastic analysis of the physical data. The received V2V message may be any V2V safety message including Emergency Electronic Brake Light (EEBL) messages.

15. Logic encoded in one or more tangible non-transitory computer readable medium for execution by an associated processor and when executed by the associated processor the logic being operable to:
-
receive by a wireless receiver a signal from a vehicle, the signal comprising a message representative of a relative safety condition between the vehicle and an apparatus; measure, by message trustworthiness logic operatively coupled with the wireless receiver, a power of the signal; determine by the message trustworthiness logic a trustworthiness level of the message in accordance with a statistical modeling of the power of the signal; and selectively generate by the message trustworthiness logic a safety alert signal responsive to the trustworthiness level of the message. - View Dependent Claims (16, 17, 18, 19, 20, 21)
