It’s really not that huge an imposition to have to adjust the driver’s seat whenever it’s time to switch different sized drivers, but it’s nice not to have to, and in the 2015 Lexus ES 350, with 10-way power seats, the seat slides forward or back automatically so it’s easier in and easier out.
And it’s not just the seat that adjusts, but also the steering wheel and side mirrors. A thoughtful design. Plus, the side mirrors are heated.
BorgWarner provides its variable cam timing (VCT) and engine timing systems for the new I4 engine family from Jaguar Land Rover (JLR).
Based on a configurable and flexible architecture to improve manufacturing efficiency and calibration strategies, the engines deliver high performance, reduced emissions and improved fuel economy.
For reliable variable cam timing, BorgWarner’s compact torsional assist (TA) phaser technology actuates rapidly resulting in improved performance, while its latest chain and tensioner technologies deliver lower friction and improve wear resistance.
Toshiba Corporation’s (TOKYO:6502) Semiconductor & Storage Products Company launched a 1-channel low-side switch IPD (intelligent power device) that adopts a small-size package for use in automotive applications.
The new product, TPD1058FA, is fabricated with a BiCD process, allowing introduction of a small-size WSON10 package (3mm x 3mm) line-up. This reduces the mounting area by approximately 70% that of Toshiba existing products in a SOP-8 package, contributing to the downsizing of equipment.
• BiCD process（N-channel DMOS output@VDSS=60V）
• Supply voltage: VDD(opr)=4.5 to 5.5V
• Built-in protection and diagnostic functions:
• Protection functions: overcurrent, overtemperature, overvoltage
• Diagnostic functions: overcurrent, overtemperature, open load
• Low Drain-Source ON-resistance:
• RDS(ON)=0.1Ω(max)@VDD=4.5 to 5.5V, Io=2A, Tch=25°C
• Small package: WSON10 (3mm x 3mm)
Twister: STMicroelectronics Simulation Tool to Design Automotive Power Actuators with Solid State Relays in VIPower(TM) M0 Technology
By Romeo Letor, Francesco Giuffre’, and Alessio Brighina
Abstract: TwisterSIM provides mixed electro-thermal and mixed system simulation environment to predict precise behavior of the VIPowerTM M0 Smart Power technology when driving automotive loads. Fast selection of suitable drivers, wiring harness optimization, faulting conditions reproduction, corner parameters assessments are functions that make this tool particularly useful to shorten design time.
Automotive control modules comprise a wide range of solid state relays to be properly selected so as to assess system reliability versus specified loads, mission profile and boundary conditions.
Texas Instruments (TI) (NASDAQ: TXN) introduced the first DLP® chipset engineered and qualified for automotive head-up display (HUD) applications. Combining the award-winning imaging qualities of DLP technology with automotive reliability, the new chipset enables head-up displays with the industry’s widest field of view (FOV) up to 12 degrees. It also enables high brightness, color and contrast levels and provides manufacturers with a scalable platform. For more information, see www.ti.com/headupdisplay.
Linear Technology Corporation announces the LTC3892, a high voltage dual output synchronous step-down DC/DC controller that draws only 29µA when one output is active and 34µA when both outputs are enabled.
The 4.5V to 60V input supply range is designed to protect against high voltage transients, ensuring continuous operation during automotive cold crank and to accommodate a broad range of input sources and battery chemistries.
Each output can be set from 0.8V to 99% of VIN at output currents over 20 amps with efficiencies as high as 96%, making it well suited for 12V or 24V automotive, heavy equipment, industrial control, robotics and telecom applications.
BMW Implements Microchip’s MOST® Technology in BMW 2 Series Active Tourer Model’s Infotainment System
Broadens Deployment From Premium Vehicles to Volume Car Models
Microchip Technology Inc. announced that the BMW Group is continuing to broaden the proliferation of MOST® technology in its vehicle infotainment networks, using Microchip’s Intelligent Network Interface Controllers (INICs).
The BMW 2 Series Active Tourer is BMW’s latest volume car model to implement MOST technology, following the company’s wide deployment among its premium models, which began in 2001.
TE Connectivity (TE) (NYSE: TEL) introduced new wire-to-board headers as part of its Power Triple Lock connector product line; thereby expanding the family of connectors targeting appliances into a growing number of HVAC, automation and control, and automotive designs.
The connectors’ combined attributes of higher-current ratings, connection reliability assurance options and higher temperature operation provide an exceptional value-added solution to customers when compared to similar pin-and-socket connectors.
The 6.0mm center line connectors in the Power Triple Lock connector family offer higher current ratings than competitive products (20A vs.18A). Their higher temperature ratings (150 C vs. 130 C degrees) help increase reliability in cooking and other high-temperature applications.
The OPEN Alliance (One-Pair EtherNet) Special Interest Group (SIG), a non-profit industry alliance established to drive wide scale adoption of Ethernet-based automotive connectivity, announced broad availability of its automotive Ethernet specifications.
One Twisted Pair Ethernet, also known as Open Alliance BroadR-Reach (OABR), delivers high-performance bandwidth of 100 megabits per second (Mbps) per port while dramatically reducing connectivity costs and cabling weight.
A growing number of automotive OEMs have deployed OABR technology to serve as a single-network platform, with the inherent security features, scalability and flexibility to be used in a broad segment of in-vehicle applications. The formation of the IEEE 802.3 task force to advance One Twisted Pair 100 Mbps Ethernet is expected to further drive wide scale adoption of the technology.

Nissan’s 2015 Murano Crossover and its 2016 Maxima include an available Driver Attention Alert (DAA) that can sound an audible chime and display an amber coffee cup symbol in the center of the instrument panel both warning a drowsy or inattentive driver to “take a break.”
The DAA includes logic to help address false detection, road curvatures, lane changes, braking and even poor road conditions. The system automatically resets when the engine is turned off. It can also be turned off by the driver if desired.
