    In today's trading environment, the commercial success of a vehicle is not guaranteed by good technical performance alone. Nowadays users expect that cars and vans to achieve high levels of performance for long periods of time. In other words they must be reliable and reliability of the whole depends on the reliability of the parts which, increasingly, includes complex electronic systems. The auth... View full abstract»

    Rover has over the last few years evolved its MEMS range of modular engine management systems, which are now fitted to the majority of the model line. Although not a safety critical device, the integrity of MEMS is vital to the performance, driveability, fuel economy, emissions and reliability of the vehicle. Detailed attention to the engineering process has produced highly reliable combination of... View full abstract»

    A Rover 820Si equipped with a controller area network (CAN) was tested for radio frequency susceptibilities in the EMC chamber at Rover Gaydon Test Centre. The car was configured in turn with two different types of twisted pair wire and a flat pair for the CAN data bus. Each type of wire was tested in the chamber at a range of frequencies and with various antenna positions. The CAN data was collec... View full abstract»

  • Application of sigma-delta modulation techniques to transducers [automotive electronics]

    Publication Year: 1993, Page(s):9/1 - 9/4
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (160 KB)

    The automotive industry is employing ever increasingly complex electronic control systems in modern vehicles. The object here is to indicate how modern control engineering design can assist in the production of a vital component in the control system chain namely the transducer. One device which has potentially a large market is the accelerometer used for ride control, engine knock, safety air bag... View full abstract»

  • The use of statecharts in developing body electronics software [for automobiles]

    Publication Year: 1993, Page(s):7/1 - 7/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (260 KB)

    The author describes one particular area of automotive electronics where good software specifications are highly desirable: that of body controllers. He goes on to describe the statechart specification notation and shows, with the help of an example, how this notation may be particularly well suited to the kind of problems body controllers pose View full abstract»

  • Integrity levels in automotive telematic systems

    Publication Year: 1993, Page(s):3/1 - 3/3
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (120 KB)

    The authors describe how there are two current methodologies for assessing the safety of an automotive system. The first simply categorises the system as being either safety-critical or not. This second approach is to classify the system into one of `m' integrity levels necessary for the development process. The value of `m' is usually either 5 or 8. This method, ideally, minimises the cost of dev... View full abstract»

  • Development of guidelines for in-vehicle software

    Publication Year: 1993, Page(s):6/1 - 6/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (204 KB)

    The most basic vehicular electronic systems may be elementary circuits such as and interior light delay. However, many microprocessor-based systems with complex embedded software are now being fitted. These electronic control systems are often employed in safety critical applications, such as engine management, antilock braking and supplemental restraints. The growth in vehicle electronics will le... View full abstract»

  • An analysis of automotive signal multiplexing-the J1850 requirement

    Publication Year: 1993, Page(s):2/1 - 2/6
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (224 KB)

    Automotive electrical systems have historically not troubled the high-technology community of integrated-circuit designers and computer software engineers. In recent years though the increasing demand by consumers for ever more luxury on-the-move has necessitated a very wide range of electronically controlled add-ons to be fully integrated with the core design of the car. This in turn has put pres... View full abstract»

  • Formal methods and how to start using them

    Publication Year: 1993, Page(s):5/1 - 5/5
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (20 KB)

    `Formal methods' are hardly headline news today. They are mandated or recommended in many emerging software development standards, and have been applied in published papers and case studies in some other industries. There are many courses and books to overcome the problem of learning the formal notation language. However, one hurdle still remains-what should be done to gain a greater understanding...

  • Integrity of a vehicle multi-ECU system

    Publication Year: 1993, Page(s):1/1 - 1/4
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (164 KB)

    The author describes how the overall integrity of in-vehicle systems which contain electronic components is dependent on three main groups of components: the vehicle sensors, which may be either electronic in nature (e.g. temperature sensors) or electromechanical (e.g. throttle position); the actuators which will be largely electromechanical (e.g. hydraulic modulator); and the interconnected elect...
