First Claim
Patent Images
1. A method of responding to unauthorized electronic access to a vehicle, comprising the steps of:
- receiving an indication of unauthorized electronic access to electronic hardware in the vehicle, wherein the indication of the unauthorized electronic access is based on a comparison of a frequency with which messages are transmitted to a threshold frequency or based on a determination that the frequency with which the messages are transmitted is outside a range of frequencies, wherein the messages are related to at least one of the following;
braking, throttle control, steering, and/or an audio system;
identifying a type of unauthorized access, wherein the identification includes;
determining a vehicle function to which the unauthorized electronic access is related; and
identifying at least one vehicle system module that carries out the vehicle function;
initiating an electronic hardware countermeasure in response to the unauthorized electronic access, wherein the electronic hardware countermeasure further comprises the step of instructing elements of vehicle electronics to ignore all incoming messages for a predetermined amount of time that are directed to the at least one identified vehicle system module;
obtaining a command set that instructs at least a portion of the electronic hardware to implement the electronic hardware countermeasure; and
communicating the command set to the portion of the electronic hardware.

8. A method of responding to unauthorized electronic access to a vehicle, comprising the steps of:
-
detecting an abnormal condition of electronic hardware in the vehicle by establishing a range of characteristic behavior for different operating aspects of the electronic hardware and monitoring the electronic hardware for indications that the electronic hardware is performing outside of the established range, and wherein the monitoring of the electronic hardware includes obtaining one or more values of at least one of the different operating aspects of the electronic hardware and comparing the obtained value(s) to one or more threshold values; determining that the abnormal condition is caused by unauthorized access to the electronic hardware based on the comparison of the obtained value(s) to the threshold value(s); initiating an electronic hardware countermeasure in response to the abnormal condition, wherein the electronic hardware countermeasure further comprises flooding a vehicle bus with data messages; generating a command set that instructs at least a portion of the electronic hardware to implement the electronic hardware countermeasure; and communicating the command set to the portion of the electronic hardware. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method of responding to unauthorized electronic access to a vehicle, comprising the steps of:
-
detecting an abnormal condition of electronic hardware in the vehicle; identifying a type of abnormal condition; selecting an electronic hardware countermeasure based on the type of the abnormal condition; generating a command set that instructs a vehicle system module to implement the electronic hardware countermeasure; communicating the command set to the vehicle system module; and carrying out the electronic hardware countermeasure for a defined period of time, wherein the defined period of time is based on;
when a notice is received by the vehicle system module, when the vehicle is turned off and subsequently turned on, or a predetermined amount of time;wherein the electronic hardware countermeasure further comprises flooding a vehicle bus with data messages. - View Dependent Claims (15, 16, 17, 18)
