The roar of engines, the screeching of tires, excitement that builds all the way to the finish line. All the cars that line up to race in this year’s DTM German Touring Car Masters series will once again have Bosch technology on board. Whether engine control units, displays, starters, generators, or any of a whole range of other components, each piece of equipment supplied by Bosch is the culmination of years of experience addressing the particular demands of motor racing: vibrations, temperature variations, extreme acceleration and braking, and peak performance over thousands of race miles every season. They also benefit from the company’s know-how from large-scale series production. “By applying our automotive development expertise to the demands of motor racing, we can supply the DTM with components that are tailored to deliver the highest levels of performance,” explains Dr. Klaus Böttcher, vice president of Bosch Motorsport.

Technology for motor racing and series production
DTM engine control units differ from those destined for large-scale series models. They are custom products that have been redeveloped from scratch. This is evident on the outside from their black, temperature-resistant housing that also keeps out dust and water. They feature special plug contacts that ensure optimum electrical conductivity even when subjected to the extreme vibrations encountered on the race track.

“At the heart of each and every ECU is its engine management software,” explains Böttcher. This lets teams customize a wide variety of engine parameters within the ranges permitted by DTM regulations – functions that cannot be altered in series-production models. These include setting the injection and ignition points with millisecond precision so as to optimize engine performance. The necessary computational power is assured by powerful processors and circuitry housed on printed circuit boards. Other functions found in series-production ECUs, such as air conditioning and cruise control, are not needed in a DTM racing car. Another difference between ECUs for the DTM and for series-production cars is data recording. DTM racing cars save all relevant engine and chassis data during the race. They are read and analyzed by the teams when the car is in the pits, providing teams with valuable information on how to further optimize the vehicle.

Detailed driver information
Another component that has been specially developed for motor racing is the DTM racing cars’ display. While the regulations stipulate that every team must have the same standard display, what each driver sees is in fact different. Every driver can access up to 12 free programmable page views during the race to see all the relevant vehicle data. For the display, too, software is the key: unlike with series-production models, the software that comes with these units allows teams to customize the information featured on each display page. All it takes is the push of a button for drivers to switch between pages on the display in their cockpit.

Bosch Motorsport supplies a wide range of other components for DTM vehicles, including starters, generators, wiring harnesses, windshield wiper direct drives, and power boxes. Apart from standard components, the teams also use Bosch Motorsport sensors, ignition components, and injection valves. Largely based on series-production technology, these components are tailored to the rigorous demands of motor racing. “To do this, we work closely with the Bosch plants’ prototype departments. That way, the teams can benefit from the know-how of a leading automotive supplier in each and every component,” says Böttcher. At the same time, findings relating to motor racing components’ robustness and service life often flow back into development work for series production. “Knowledge transfer between motor racing and series production is not a one-way street,” says Böttcher, describing the collaboration between the company’s development departments.

Engine management in every series
From the Volkswagen Scirocco R Cup and the Porsche Carrera Cup Deutschland to the FIA Formula 3 European Championship, all the support series for the DTM rely on Bosch engine management equipment and a host of other components the company supplies.

Bosch Motorsport is part of Bosch Engineering GmbH, a subsidiary specializing in engineering services. The company can look back on a long tradition of involvement in motor racing, with Bosch technology having made its successful debut in racing cars in 1901.

Bosch Engineering GmbH is a wholly owned subsidiary of Robert Bosch GmbH and is head-quartered in Abstatt, Germany. As a systems development partner to the automotive industry since 1999, the company with its more than 2,000 associates offers development services for powertrains, safety and convenience systems, and electrical and electronic systems – from the original concept to series production. Specialized in electronics and software, it draws on Bosch’s proven large-scale series production technology to develop tailored solutions for a wide variety of applications in passenger cars, commercial vehicles, off-highway and recreational vehicles, and in rail applications, ships, and industry. Bosch Engineering GmbH also coordinates all the Bosch Group’s motorsports activities.
