Abstract. Electronics Throttle Control System (ETCS) is the principal electronic unit in all fuel injection engine motorbike, augmenting the engine performance efficiency in comparison to the conventional carburetor based engine. ETCS is regarded as a safety-critical component, whereby ETCS malfunction can cause unintended acceleration or deceleration event, which can be hazardous to riders. In this study, Hazard Analysis and Risk Assessment, an ISO26262 functional safety standard analysis has been applied on motorbike's ETCS to determine the required automotive safety integrity level. Based on the analysis, the established automotive safety integrity level can help to derive technical and functional safety measures for ETCS development.

“…Due to the availability requirements, a redundant power supply is necessary [31,[72][73][74][75]. This is already in place for electric and hybrid cars, which possess a higher voltage network (up to 400 V) for propulsion and a low-voltage (12 V or 48 V) supply for standard consumers [31,76].…”

A growing interest in Electromechanical Brakes (EMBs) is discernible in the automotive industry. Nevertheless, no EMBs have ever been deployed for series production, although countless publications have been made, and patents have been filed. One reason for this is the need for the optimization of functional safety. Due to the missing mechanical/hydraulic link between the driver and the actuator, sophisticated concepts need to be elaborated upon. This paper presents the current state of the art of safety concepts for EMB systems (only publicly available publications are reviewed). An analysis of current regulatory and safety requirements is conducted to provide a base for design options. These design options are explored on the basis of an extensive patent and literature research. The various discovered designs are summarized and analyzed according to their (a) EMB actuators; (b) control topology; (c) energy supply; and (d) communication architecture. This paper concludes by revealing the weak points of the current systems.

“…However, as pointed out by [16], much of the testing is done in the verification and validation phase and the usage of fault injection on a model level will lead to a development of a correct system right from the initial phases. Functional architectures are provided in [13], [6], [2] for systems such as steer-by-wire, automated driving and various drive-by-wire systems in a vehicle. Moreover, [2] also explains in detail the development of a steer-by-wire system including functional requirements and functional architecture on system and sub-system levels.…”

“…However, adding new functionalities and validating the operational safety of a new subsystem in the existing system framework increases development time. Thus the reconsideration of fundamental electronics in terms of functional behaviour will be highly beneficial in terms of reducing complexity and improving operational safety as proposed in [2]. This will not only support the development of innovative functionalities, but also make them safer without increasing the development time.…”

Modern automobiles can be considered as a collection of many subsystems working with each other to realize safe transportation of the occupants. Innovative technologies that make transportation easier are increasingly incorporated into the automobile in the form of functionalities. These new functionalities in turn increase the complexity of the system framework present and traceability is lost or becomes very tricky in the process. This hugely impacts the development phase of an automobile, in which, the safety and reliability of the automobile design should be ensured. Hence, there is a need to ensure operational safety of the vehicles while adding new functionalities to the vehicle. To address this issue, functional models of such systems are created and analysed. The main purpose of developing a functional model is to improve the traceability and reusability of a system which reduces development time and cost. Operational safety of the system is ensured by analysing the system with respect to random and systematic failures and including safety mechanism to prevent such failures. This paper discusses the development and validation of a functional model of a conventional cruise control system in a passenger vehicle based on the ISO 26262 Road Vehicles -Functional Safety standard. A methodology for creating functional architectures and an architecture of a cruise control system developed using the methodology are presented.
