"Electro Gyro-Cator" New Inertial Navigation System for Use in Automobiles

1983-02-01
830659
The Electro Gyro-Cator allows a driver to monitor his progress, plot and follow courses to a destination, select alternate routes, and drive more safely on unfamiliar roads or at night. Employing a sealed helium gas-rate gyro, the Electro Gyro-Cator offers visual display (CRT display) of a car's present location, direction and route, with overlay maps for fast, simple route selection and monitoring. The primary elements of the unit include trip and direction sensors, a 16-Bit central processing unit, a CRT display screen and a collection of transparent overlay maps fitted to the screen.

"Quattro"-Drive for Every Day Driving

1984-01-01
845070
An essential feature of the Audi Quattro permanent four-wheel drive system is in the inter-axle differential located on the hollow output shaft in the gearbox: the drive is taken from this differential forward to the front differential through the inside of the hollow shaft, and rearward to a propellor shaft driving the rear differential. The major advantages in everyday driving include improved traction and a reduced tendency toward throttle induced changes of attitude. The greater traction allows not only better progress in difficult road conditions; it also gives better acceleration in difficult traffic situations, such as when joining a busy main road. The more easily predictable handling response to throttle changes means that Quattro vehicles have better tracking stability. Altogether, the active safety and "roadability" are considerably improved.

<PP/SEBS> Compounds: Sealing an Easier Future for Automotive Designers and Specifiers

2002-07-09
2002-01-1997
There is a definite trend toward the increasing use of “Glass Encapsulation Technology” in the automotive industry. In this technology a glass object such as a window is placed within a mould and an elastomer is injected around the window giving a tight sealing system. A wide variety of materials are currently used as the sealing materials in either static or semi-static encapsulated glazing systems, including a wide range of “elastomers”. New thermoplastic elastomer compounds are being developed that are characterized by their consistent properties; including high melt-fluidity, very good surface appearance, sealing properties, and resistance to weathering. Compound performance is highly dependent on formulation variables as well as the chemistries of the base materials. KRATON® SEBS polymers1 are block copolymers of styrene and ethylene/butylene.

(R)evolution of E/E Architectures

2015-04-14
2015-01-0196
This paper presents an overview of the evolution & revolution of automotive E/E architectures and how we at Bosch, envision the technology in the future. It provides information on the bottlenecks for current E/E architectures and drivers for their evolution. Functionalities such as automated driving, connectivity and cyber-security have gained increasing importance over the past few years. The importance of these functionalities will continue to grow as these cutting-edge technologies mature and market acceptance increases. Implementation of these functionalities in mainstream vehicles will demand a paradigm shift in E/E architectures with respect to in-vehicle communication networks, power networks, connectivity, safety and security. This paper expounds on these points at a system level.

(Test Developed For) Classifying Valve Bridge Cracking Solutions in Cylinder Heads

1995-02-01
950029
The testing system developed will decrease the time and the costs involved in evaluating cylinder head valve bridge designs. The test uses actual data generated from engine testing to recreate the valve bridge cracks that occur during dynamometer and vehicle testing. This paper focuses on the system description, the test development, design modifications, and the test results obtained. Testing shows that this method correctly separates valve bridge designs by test cycle life using statistical methods. It is a cost effective and timely alternative to dynamometer testing.
