Maxim Integrated Products Inc. has introduced a family of Gigabit Multimedia Serial Link (GMSL) serializer/ deserializer (SerDes) chipsets that can be used either with shielded twisted pair (STP) or lighter and less costly coax cabling, thus offering flexibility for engineers designing high-resolution advanced driver assistance systems (ADAS).
Current vehicle designs use STP cables to drive data to automotive infotainment displays; however, automakers are turning instead to coax cabling because it can lower cable cost and weight by up to 50%.
Freescale Semiconductor introduced the MAC57D5xx, a new family of ARM® Cortex®-based single-chip, triple-core microcontrollers (MCUs) designed for automotive instrument clusters.
With more than 1.7x higher performance than any currently available automotive instrument cluster MCU, the new devices support complex graphics, including heads-up displays that previously required multiple components.
High-end automotive instrument clusters typically incorporate multiple external components, including a main processor, graphics unit, external SRAM, and dedicated circuitry to manage heads-up display warping and other sophisticated functionality. The cost and complexity of integrating these multiple parts previously restricted this functionality to the premium car segment.

Toshiba Corporation introduced the TB9005FNG, a 5-volt constant voltage regulator for automotive systems.
The TB9005FNG supports 1A or higher output current in combination with external power transistors. It can supply more than 2A output current when used with Toshiba’s TTB002 or TTA005 power transistors, thus allowing use in automotive applications that require high output current.
The TB9005FNG incorporates system reset functions for reset of microcontrollers when their voltage is lowered or clock signals are cut off, which contributes to improved safety for automotive systems.
- Part Number: TB9005FNG
- Output Voltage:5.0V±0.15V
dSPACE has released the XSG AC Motor Control (XSG = Xilinx System Generator) Library software for developing control systems for electric drives.
The library enables engineers to program Field Programmable Gate Arrays (FPGA) for use in control tasks with dSPACE MicroAutoBox II and SCALEXIO systems, as well as modular dSPACE hardware.
By moving control loops onto reconfigurable hardware, engineers for the first time can achieve execution speed of over 100 kHz and conveniently develop highly dynamic electric drive systems for applications demanding precise position and speed.
TRW Automotive Holdings Corp. recently started production of its roof airbag technology on the Citroën C4 Cactus. The “bag in roof” replaces passenger airbags typically mounted in the instrument panel and can allow for improved interior design aesthetics, ergonomics and functionality while saving space in the instrument panel.
Dirk Schultz, engineering director for TRW’s Inflatable Restraint Systems commented: “Interior design requirements have evolved significantly over the last decade with some manufacturers looking for more instrument panel space for the latest multimedia technologies or a means of increasing storage, or are proposing more open and airy cockpit environments.

Freescale Semiconductor and Broadcom Corporation together launched the Freescale Qorivva MPC5606E, a single-chip microcontroller (MCU) that integrates the Broadcom BroadR-Reach PHY. Its predecessor, the dual-chip MPC5604E, is currently in production. Freescale is sampling the new device now and expects that will be available in production quantities by the end of 2014.
Among other applications the device targets 360-degree “surround view” camera systems, which are used in applications such as park assist and blind spot detection. Automotive OEMS prefer peripheral cameras to be miniaturized and unobtrusive to maintain vehicle aesthetics. Smaller cameras can be more easily hidden within design features of the car, such as a front grill, bumper or wing mirror.

This article describes the concept of virtual hardware “in-the-loop” (vHIL). The goal of vHIL is to frontload the testing process by enabling software teams to create and run their software tests before the actual ECU hardware is available. Higher quality tests, higher quality software and a more streamlined “in-the-loop” flow is the intended outcome of this solution.
Besides describing how vHIL fits in the general Model-In-the-Loop (MIL) – Software-In-the-Loop (SIL) – Hardware-In-the-Loop (HIL) process, this article describes in some detail how a virtual prototype model created with Synopsys Virtualizer can be integrated with a MathWorks Simulink plant model. This integration is fundamental for enabling a vHIL solution.

It’s no secret that the cars we drive today, and especially those we will drive in the near future, have huge amounts of sophisticated software aboard. By some accounts the number of lines of code in a car can significantly exceed the number of lines of code in a modern commercial jetliner. And as with the jetliner, we are entrusting our safety to the reliability of this software.

Thanks to the emergence of increasingly capable and cost-effective processors, image sensors, memories and other semiconductor devices, along with robust algorithms, it’s now practical to incorporate computer vision into a wide range of embedded systems, enabling those systems to analyze their environments via video and still image inputs.

This article describes what start-stop is and the prerequisites for an automotive start-stop system, including its implementation and benefits.
The fuel savings and CO2 reductions are in the five to 10 percent range. With fuel prices rising, taxes increasing for high carbon-oxide emissions, and governmental requirements for vehicles with lower and lower emissions, various measures are needed to increase efficiency and lower emissions.
