Abstract: Presented herein are intrusion detection systems and algorithms for networked vehicle controllers and devices, methods for making/using such systems and algorithms, and motor vehicles with a network of ECUs and network-profiling intrusion detection capabilities. A method for detecting intrusions into an onboard network of vehicle controllers includes determining the current state of operation of a vehicle, and identifying a network traffic pattern table corresponding to the vehicle's current state of operation. Network traffic flow for one of the in-vehicle controllers is monitored when exchanging data over the Ethernet communication interface while the motor vehicle is operating in the current state of operation. The method then determines if a traffic characteristic of the monitored network traffic flow is outside a calibrated boundary that is determined from the network traffic pattern table. Responsive to the monitored network traffic flow characteristic being outside the calibrated boundary, the method executes a remedial action response.

Abstract: Embodiments include methods, systems and computer readable storage medium for a method for making temporal corrections to position data received a plurality of components. The method includes receiving, by a processor, vehicle location data and a time stamp associated with the vehicle location data from one or more components. The method further includes calculating, by the processor, a time difference between the time stamp and a current time received from the one or more components. The method further includes determining, by the processor, a time offset using the time difference and a distance travelled between the time stamp and an occurrence of the determination for each of the one or more components. The method further includes providing, by the processor, a corrected vehicle location using the time offset for each of the one or more component.
