Typical applications of automotive telematic systems include automotive navigation systems using Global 15 Positioning System technology, emergency warning systems for vehicles, both in vehicle-to-vehicle and in vehicle-to- infrastructure settings, emergency calling systems in the case of accident or break-down of the vehicle, integrated hands- free cell phones, wireless safety communications, automatic driving assistance systems, mobile data, radio, and tele- vision, and vehicle tracking, e.g., as part of fleet management systems, but are not limited to these. Telematic systems may comprise electronic, electromechanical, and electromagnetic devices. Intelligent vehicle technologies are utilized 20 for safety and commercial communications between vehicles or between a vehicle and an external sensor or an external server. [0003] One of the latest additions to the world of automotive telematics is the provision of on-board logging and on- board diagnostics systems for vehicles interacting with telematic components of the vehicle. Current vehicle systems employ an ’on-board diagnostics system’ in order to detect problems with components of the vehicle early on. The 25 detected problems are reported to the driver. In addition, they are generally recorded for later analysis by a specialist using diagnostic trouble codes (DTCs). This typically allows the service provider to more rapidly identify the cause of a problem once a vehicle has been returned for inspection. Typically, a scan tool is used to read the diagnostics information memory. To this end, the scan tool is generally physically connected to the on-board diagnostics system. [0004] Tracking of a system state of a complex product, like an automotive telematic system, combined with the ability 30 of detecting problematic behavior as early on as possible is key in preventing serious vehicle accidents as well as ensuring a (near) problem-free product life cycle. Particularly, malfunctions of safety relevant telematics components, as for instance for the automatic dispatching of an emergency call in the case of an accident or break-down of the vehicle or for the exchange of information concerning hazardous road conditions between vehicles and/or back-end servers, need to be detected as early as possible or ideally be anticipated by constant monitoring of the involved telematics 35 components and/or (software) application components. With increasing complexity of nowadays telematics systems and ongoing integration of electronic components, logging, diagnosing, and correction of malfunctions of the involved (software) application components have gained relative importance compared to hardware diagnostics alone, which so far were at the heart of on-board diagnostics standardization efforts in the automotive industry. [0005] System processes and activities are usually carried out by or in interaction with (software) application compo- 40 nents in the automotive environment and are typically composed of a large number of sub-tasks executed by sub- components that interact with each other. In many cases, the combined behavior of the sub-systems must be taken into account in order to correctly identify the root cause of an error in the case of a malfunction of a system. Furthermore, processes often exhibit volatile behavior in case of errors, i.e., system problems may recover by themselves due to a change of the external conditions. Specific examples for such systems are the online and connectivity systems which 45 may fail under conditions of no network coverage but recover as soon as network coverage is reached. [0006] An automated diagnostics tool needs to be able to take these characteristics into account in order to avoid inconclusive results. In a volatile system, it is desirable to not only extract the relevant errors that have occurred, but also, to provide information on the overall system reliability and performance (for instance, the number of successfully completed use cases vs. failed ones). Since many errors in complex systems involving application components and 50 telematic components are not safety relevant and may additionally be volatile, it is desirable to decouple servicing of the telematic system from the standard vehicle inspection cycle. Particularly, a servicing of the telematic system driven by demand, ideally prior to customer complaints, is in the interest of both customers and service providers. [0007] Further, the increasing complexity and interconnectivity of telematic systems in current vehicles lead to an ever larger quantity of possible errors, root causes, and error messages, thus rapidly exceeding the capabilities of on-board 55 diagnostics systems and trained diagnosticians, who, in many cases, have to diagnose occurred problems ’by hand’ by running diagnostics tests as part of a vehicle service. Standardized error codes or diagnostic trouble codes can help but often hamper technological progress in a highly competitive environment. Considering the rather long product life cycle of vehicles, as opposed for instance to smart phones, and the limited capabilities for system upgrades of deployed 3 EP 2 680 534 B1 telematic systems, a genuinely extensible logging and diagnostics system as opposed to current, more rigid solutions is also desirable.

To integrate these advanced features, numerous electronic systems are needed. Several control modules are used for enabling these systems to act jointly. Engine Control Module is a crucial part of vehicle’s Engine Management System (EMS). Expanding interest for progressively controlled security features, traveler comfort, and operational ease in vehicles requires an exhaustive utilization of electronic control units (ECU). The Engine Control Module (ECM) provides the brains for the engine of the vehicle. It controls the fuel mixture; timing and emissions control system and variety of other systems and sensors. This paper presents a review on ECU, different types of control units in vehicle, automotive communication protocols and working of an ECU.

  • Security Threats and Countermeasures for Connected Vehicles
    DEGREE PROJECT IN TECHNOLOGY, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2019 Security Threats and Countermeasures for Connected Vehicles Xuwei Gong <[email protected]> KTH ROYAL INSTITUTE OF TECHNOLOGY ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Abstract With the rapid development of connected vehicles, automotive security has become one of the most important topics. To study how to protect the security of vehicle communication, we analyze potential threats for connected vehicles and discuss countermeasures to mitigate these threats. In this thesis, we examine 25 services that connected vehicles can provide. Entities, connections, and message flows in these services are investigated and synthesized into a vehicle network structure. The 25 services are divided into six use cases including: infotainment service, remote monitoring, device control, Vehicle-to- everything (V2X), diagnostics service, and in-vehicle Intrusion Detection System (IDS). We establish communication models for these use cases and analyze the potential threats based on Confidentiality, Integrity and Availability (CIA) criteria. We discuss possible countermeasures that can mitigate these threats based on existing network security techniques. Each alternative countermeasure’s advantages and limitations are presented. To filter possible attacks, we investigate and design firewalls in four components of a vehicle: Dedicated Short-Range Communications (DSRC) module, gateway, Telematic Control Unit (TCU), and Human-Machine Interface (HMI). We also simulate a firewall for an HMI application by building a communication model in Python. Keywords Connected vehicle; Use case; Threat analysis; Countermeasures i Abstract Med den snabba utvecklingen av anslutna fordon har bilsäkerhet blivit ett av de viktigaste ämnena. För att studera hur man skyddar säkerheten för fordonskommunikation analyserar vi potentiella hot mot anslutna fordon och diskuterar motåtgärder för att mildra dessa hot.
