Automotive radar is a key technology in delivering active safety systems that play a major role in reducing traffic fatalities. Active safety systems include adaptive cruise control and collision warning systems with automatic steering and braking intervention, lane departure warning and electronic stability control. In a collision warning system, the automotive radar consisting of a 77 GHz transmitter emits signals that are reflected from objects ahead, at the side and to the rear of the vehicle and are captured by multiple receivers integrated throughout the vehicle. The radar system can detect and track objects and trigger a driver warning of an imminent collision and initiate electronic stability control intervention. Continue reading
After completing the first circuit of the globe, this year the Automotive Simulation World Congress (ASWC) 2015 returns to Detroit. The conference is now exactly two weeks away — to be held on June 2 and 3 — and I am really excited about it. If you haven’t registered and reserved your seat, please take a moment to register. You don’t want to miss this great event. And if you don’t know what it’s all about, read on for more information. Continue reading
This is the third year that ANSYS hosted the Automotive Simulation World Congress (ASWC), an international conference focused on engineering simulation in the ground transportation industry. The ASWC is an annual conference that rotates between the three major regions of the world. In previous blogs, I wrote about the 2012 and 2013 ASWC’s held in Detroit and Frankfurt respectively. This year the conference was held in Tokyo on October 9 and 10. Continue reading
Imagine you have an oil pump in your car that has its outlet blocked. The pump is trying to throw the oil out but since the outlet is blocked the pressure in the pump keeps increasing. The excessive pressure that develops in the pump can be catastrophic to its strength and therefore life. This is precisely what happens when you try to operate the pump under extreme cold conditions, when the viscosity of the lubricant increases so much that the pump almost behaves as if its outlet has been blocked.
This is a very common design scenario for pump manufacturers. Estimation of what is called as “shut-off” pressure and its implications on the structural integrity of the pump are key concepts that every pump manufacturer should bear in mind while designing pumps. Interestingly, simulations today allow manufacturers to develop deep understanding of such phenomenon and help them to design pumps, that perhaps they could not have, with just physical testing and prototyping.

Mention of EMI/EMC-induced automotive system failure in the press last week coincided with one of the bigger technical conferences held annually in Silicon Valley – DesignCon. It was in this conference two years ago that we organized a workshop on chip–package–system simulation methodologies specifically as they pertain to EMI/EMC analysis.
Electromagnetic interference, coupling and susceptibility are complex topics. To predict such an event or occurrence requires design teams separated by organizational boundaries to collaborate effectively “outside” the silos they reside in. An automotive system design company working on the next-generation air-bag control system will be responsible for designing the printed circuit board (PCB) to meet stringent performance, reliability and cost metrics. Its teams typically perform numerous simulations to ensure that the board, by itself, meets the requirements outlined for the team. However, PCBs are passive electrically. They (along with the cables) radiate only when the integrated circuit (IC) that is present on these PCBs performs the necessary operations and generates current flow through the various traces.

On October 30 – 31, ANSYS will be hosting the Automotive Simulation World Congress (ASWC) in Detroit, Michigan. This international event is being held at the Detroit Marriott at the Renaissance Center and is solely focused on the automotive industry, including vehicles for road, rail, racetrack and off-highway and provides a forum for sharing and debating new practices, issues and industry trends. You’ll learning about the latest developments in engineering simulation applicable to the automotive industry, and networking with peers. Continue reading
The Formula 1 engineer is the royal class of automotive engineering. Even the smallest improvements in aerodynamics, engine performance, traction or durability can influence a team’s success or failure. Each of the F1 teams have a large number of highly qualified engineers working on each part of the car to improve its overall performance. Where do these engineers come from? Is there a given educational path a person should follow to get a chance to work for an F1 team? Next to a sound engineering education and the right motivation and will, probably not. But there are some initiatives that are helpful on the way to the automotive engineering summit. One of them is Formula SAE/Formula Student. Continue reading
