The vehicle control system of the present disclosure includes a meter-side control device that is installed in a vehicle and can measure the total distance traveled by the vehicle, and a backup device that can obtain a copy of the total distance measured by the meter-side control device. Data communication between the meter-side control device and the backup device uses an authentication signal using a common key, and a new communication between the meter-side control device and the backup device When registering a common key, the larger value of the total mileage value stored in the meter side control device and the total mileage value stored in the backup device is sent to the meter side control device. Total mileage.

Aspects provided herein provide methods, apparatus, and a non-transitory computer storage medium storing computer instructions for vehicle disturbance alerting in a network. The method begins with receiving a vibration alert from a sensor installed in a vehicle. The sensor may be an accelerometer, gyroscope, or motion-capable sensor and is in communication with a low power radar sensor that is also installed in the vehicle. A low power radar sensor is activated in response to the vibration alert. At least one radar signature is received from the low power radar sensor. The radar signature is then compared with at least one driver radar signature. The driver radar signature is recorded when a driver occupies a driver seat position and operates the vehicle. Based on the comparison, a determination is made whether to issue a vehicle disturbance alert.

ECU 2 has a function for discarding data when continuous dominant equal to or greater than 6 bits is received during data reception. A data excluding device 5 is connected to a bus 3 to which the ECU 2 is connected. When ID of data received through the bus 3 matches ID of an illegal ECU detected by a theft sensor 4, the data excluding device 5 outputs 7 bits continuous dominant to the bus 3, and then stops output of the dominant.

An anti-fraud method for use in an in-vehicle network system including a plurality of electronic control units that exchange, in an in-vehicle network, data frames, each having added thereto a message authentication code (MAC). The method includes generating a first MAC by using a MAC key and a value of a counter that counts a number of times a data frame having added thereto a MAC is transmitted to the in-vehicle network. The method also includes performing verification that the data frame received has added thereto the generated first MAC and incrementing a number of error occurrences when the verification has failed for the data frame, the data frame including a predetermined ID. When the number of error occurrences exceeds a predetermined threshold, a process associated in advance with the predetermined ID is executed.

Systems and methods for providing vehicle information to operators and service people without the use of a tool enabling communication directly between the vehicle and the operator or service person. In particular, systems and methods are provided for receiving a vehicle data request from an operator mobile device application, identifying a vehicle in close proximity to the operator mobile device, obtaining most recent vehicle data, and transmitting the requested vehicle data to the operator mobile device. Additionally, systems and methods are provided for the operator to request various capabilities with respect to the vehicles, such as vehicle access.

Disclosed are devices, systems and methods for securing wireless communications between a remote monitor center and a vehicle by using redundancy measures to increase the robustness of the system. In some embodiments, a system may include redundant communication channels, deploy redundant hardware and software stacks to enable switching to a backup in an emergency situation, and employ hypervisors at both the remote monitor center and the vehicle to monitor hardware and software resources and perform integrity checks. In other embodiments, message digests based on a cryptographic hash function and a plurality of predetermined commands are generated at both the remote monitor center and the vehicle, and compared to ensure the continuing integrity of the wireless communication system.

A method used in an on-board network system, having electronic controllers that exchange messages and a fraud-detecting electronic controller. The method includes receiving an inquiry for a vehicle status indicating whether a vehicle in which the fraud-detecting electronic controller is installed is running from an external device, transmitting the vehicle status to the external device, and determining whether a message transmitted conforms to fraud detection rules. The method also includes receiving from the external device the delivery data, including updated fraud detection rules and network type information indicating a network type that the updated fraud detection rules are to be applied. The method further includes determining whether the vehicle is running, and whether the network type information indicates a drive network that is connected to an electronic controller related to travel of the vehicle. When the network type information does not indicate the drive network, updating the fraud detection rules.

An anti-fraud method for use in an in-vehicle network system including a plurality of electronic control units that exchange data frames, each having added thereto a message authentication code (MAC), via a bus includes receiving a data frame transmitted on the bus, and generating a first MAC by using a MAC key and a value of a counter that counts a number of times a data frame having added thereto a MAC is transmitted. The method also includes performing verification that the data frame received has added thereto the generated first MAC and incrementing a number of error occurrences when the verification has failed for the data frame, the data frame including a predetermined message ID. When the number of error occurrences exceeds a predetermined threshold, a process associated in advance with the predetermined message ID is executed.

A vehicle security system comprising a first interface, an immobilizer electronic control unit and an immobilizing electronic control unit, each of which is connected to a CAN bus. The security functions are installed on the immobilizer electronic control unit which can be accessed by a user using a vehicle access code. The information is communicated over the CAN bus in an encrypted format.
