For demanding applications such as automotive electronics, tantalum capacitors have been used for years because of their excellent stability at high temperature. The type typically specified for automotive use has a manganese dioxide (MnO2) cathode, which can withstand temperatures up to 200°C.

However, the manganese dioxide cathode devices have a disadvantage: their equivalent series resistance (ESR) isn’t as low as the polymer cathode types used in consumer electronics. Until recently, polymer cathode capacitors weren’t suitable for use at automotive temperatures and they also struggled to meet the humidity requirements for AEC-Q200.

Cars are undoubtedly safer now than they ever have been, as evidenced by the steady decline of road fatalities. However, at the same time the number of injuries is actually increasing – passive safety technologies such as seat belts and airbags have simply made accidents more survivable. It is obvious that what is needed is ways of avoiding the accidents in the first place. Meanwhile traffic congestion, and its resulting environmental impact, continues to be a growing problem in cities around the globe. One simple technology has the potential to address all of these issues.

The AUTOSAR development partnership started more than ten years ago with the promise to manage the increasing electrical/electronic complexity in different domains. The objective was to lower the cost of standardized basic software, support safety, maintain ability, and exchangeability while enabling more powerful tool chains to be constructed through standardized interfaces.

Ten years of AUTOSAR have demonstrated the potential of standards offering applicability across competitive boundaries. However, as long as the standardization continues to be confined to the specification level, the effort required for integration, configuration, and
testing remains unnecessarily high. Initiated by Bosch, the non-profit association COMASSO e.V. has embarked on the road that will lead to the provision of an industry-wide reference for AUTOSAR Basic Software.

Smart In-Vehicle Cameras Increase Driver and Passenger Safety

October 3, 2014  by  


Figure2

One area of ADAS that is seeing a particularly significant increase in interest from OEMs is the use of in-cockpit cameras to monitor the driver and passengers. Today’s in-cockpit ADAS technology can help determine if the driver is distracted or drowsy, and then alert the driver to bring his or her attention back to the driving task at hand. Additionally, by using information about the driver’s head and body position provided by this same system, appropriate deployment of the airbag (intensity, location, etc.) can be implemented in crash situations.

Implementation of Multiplexing Technology in Automobile Cable Harnessing Infrastructure

The number of electronic control units (ECUs) being incorporated into vehicles has risen at an almost exponential rate over the last few years – as the complexity of the safety, infotainment and comfort systems across the board (from economy models right through to luxury ones) has continued to increase at a rapid pace. This has serious and far-reaching implications for car manufacturers, since the cabling that is needed to connect all this hardware together takes up more space (which is now at a premium) and also adds to the overall weight of the vehicle (which impacts directly on its expected fuel efficiency). By networking or multiplexing it will be possible to overcome the restrictiveness of conventional, increasingly outdated wiring arrangements and create a more effective system for the distributing of crucial data.

Advanced Product Line Engineering Puts the Auto Industry in Overdrive

Today’s vehicles must be responsive to the driver’s slightest of intentions, while providing the highest levels of safety and reliability under the most extreme conditions. Manufacturers have turned to increasingly sophisticated software and electronics, adding yet another layer of complexity as well as the opportunity for expensive and image-bruising defects and recalls. Product line engineering (PLE) is a recognized discipline within systems engineering that is being applied to the automotive world to address precisely these kinds of complexities.

How to Set-up a Knock-sensor Signal-conditioning System

August 22, 2014  by  


slyt580_fig1
Engine knock occurs in engine cylinders because of improper ignition timing or faulty components. Modern cars incorporate knock-sensor systems for engines to minimize knocking, which can maximize engine lifetime, increase power, and improve fuel efficiency. This article discusses engine knock basics and how to set up a knock-sensor signal-conditioning system.
