Microchip: A Partner in Your Automotive SuccessFunctional Safety and ISO 26262With their ever-increasing use in automotive designs, electronics play an essential role in vehicle operation, user convenienceand the protection of human life. Given the widespread use of electronic systems in automotive applications, it can be difficultto understand how essential their correct operation is to the control of the vehicle. As long as these electronic systemswork properly, the safety of the people in and around the vehicle depends primarily on the driver’s skill and driving practices.But what happens when the electronics malfunction and prevent the driver from maintaining proper control? For example,an airbag may suddenly deploy while the vehicle is in motion, without being triggered by a crash. What if the driver doesn’teven know that the electronics are malfunctioning, as might be the case when the image is frozen on a rear view camera?All electronics are susceptible to random failures. Although the failure rate may be quite low for individual components, theincremental use of electronics in a vehicle significantly increases the potential for failures to occur. Most software engineerswill also agree that eliminating bugs is becoming more difficult as software grows in size and complexity. Functional safety isthe ability of an electronic system to detect when there is a fault, make the driver aware of the fault and put the vehicle in amode that allows the driver to maintain safe control. Returning to the example of the airbag, the diagnostics should identifythe fault, disable deployment and turn on a warning light to inform the driver that the system is not working properly.Recognizing the need to focus on the functional safety of electronic systems, the automotive industry has adopted ISO 26262,which is a derivative of IEC 61508. This automotive-specific standard applies not only to the design and test of electrical andelectronic systems, but to the entire life cycle of the product, from concept to eventual disposal and recycling of the vehicle. Theimplementation of ISO 26262 supports the ability of component suppliers, system suppliers and automotive OEMs to discuss,evaluate, design, measure and ensure an appropriate level of functional safety for electrical and electronic control systems.Ensuring a functionally safe system requires a comprehensive analysis of the hazards and risks. A robust system design,development and validation process is also required, with proper selection and usage of both hardware and softwarecomponents. ISO-26262 defines a series of steps to assign an acceptable level of risk for a system, to minimize errors duringthe product development process and to determine if the end product achieves the required level of functional safety. Theutilization of this common standard also enables a team of people working together on a project who are distributed around theworld to more easily discuss complex functional safety topics.Microchip enables functional safety in automotive embedded designs—from electronic door handles to electronic steeringsystems—by providing you with the right building blocks to create a system that meets the most stringent requirements.

Advanced Driver Assistance SystemsDriver Assistance with MOST Technology: Powerful Network Infrastructure for ADAS SolutionsCameras are the key to many modern automotive applications like surround-view and lane departure warning. Depending onthe application and the number of cameras, one or more video signals need to be transported to a control unit for displayand/or signal processing. Digital video transmission with low latency is essential to match the application requirements.The MOST network has been designed from the beginning as time-division-multiplex network to provide data transmissionwith minimum latency and premium quality of service. In a multi-camera application, the cameras are synchronized via theMOST network to sample the video frames at exactly the same time with low jitter. The MOST network transports streamingdata—like high definition video—as well as control data and packet data over the same cable. The MOST network controlseach camera, and a camera back channel is implicitly supported by the nature of MOST technology. Additional data—such asparameter lists, camera settings and/or accompanying image information—can be sent to the control unit as packet data.In addition to cameras, various sensors within the car can be networked with MOST technology to allow for central and/or de-central sensor data fusion. MOST technology can be used with an electrical and/or optical physical layer and with avariety of topology options including ring, star, daisy-chair, double ring or even with a mixture of topologies. This flexibilityand the ability to easily create seamlessly connected clusters support the implementation of redundancy systems.MOST technology delivers a functional system model to enable a scalable, modular and expandable driver assistancesystem design based on interchangeable and common sensors and control units.Technical Key Benefits Real-time data transfer: digital high-definition videotransmission with ultra-low latency Highest quality of service Flexible topologies: star, daisy chain, ring andany combination Automotive proven coax physical layer: full duplex andpower over cable supported Synchronized devices Wide range of data types: streaming, control, packetand IP over one cable Remote control Single-chip solution for lean camera nodes150 Mbps150 MbpsTop-ViewECUHead UnitCoaxFigure: Top-view diagramApplication Example: Top-View (Surround-View)The example below shows a Top-View Electronic Control Unit (ECU) connected to four high-resolution cameras.
