www.chinabuses.org: On September 27th, BOSCH exhibited a series of advanced technologies for improving the economy and safety of commercial vehicles in Booth B10 Hall 17 of IAA 2012. Chairman of BOSCH Automotive Group Bernd Bohr said: "With a raft of innovations, we want to reduce commercial-vehicle fuel consumption by another 15 percent by 2020". Despite the turmoil in global markets, Bosch continues to see good prospects for the company’s development, and especially also for its commercial-vehicles business. “Mileage is increasing, but so are expectations when it comes to efficiency and environmental protection."
Bosch technology saves logistics companies 10,000 euros per truck and year
As the largest supplier to the industry, Bosch is taking innovative approaches to make commercial vehicles even more efficient. “Even now, trucks are up to 15 percent more efficient than cars. Making them significantly more economical calls for new solutions,” said Bohr, explaining the challenge automakers and suppliers face when tasked with further reducing consumption and C02 emissions. Given today’s fuel prices and a total annual mileage of 130,000 kilometers, the target for logistics companies now is to bring down operating costs by nearly 10,000 euros per vehicle per year.
To achieve this, Bosch is further exploiting the potential fuel economy of already existing technologies, and developing additional innovations as well. When it comes to common-rail systems, for example, Bosch engineers are working to increase injection pressure still further, to 3,000 bar. Even today, the interplay between high-pressure injection and the Denoxtronic urea-metering system reduces fuel consumption by 5 percent. Both technologies are increasing their market penetration. In the coming year, Bosch expects to sell 2.5 million common-rail systems and more than 800,000 Denoxtronic systems in the commercial-vehicle sector.
Bosch innovations for even more efficiency
Currently, some 60 Bosch engineers are working on hybrid drives for commercial vehicles weighing more than 12 metric tons. The company’s expectations for the parallel hybrid are that it will reduce fuel consumption by 6 percent, even over long distances. In delivery traffic, consumption will be cut even more significantly – by up to 20 percent. Bosch has set itself the goal of launching commercial-vehicle hybrid systems in the second half of this decade. The systems have been designed so that logistics companies can recoup the extra cost within three years.
The increasing interconnection of vehicle systems is a Bosch specialty. The new “Eco.logic motion” system is part of this trend. On the basis of navigation data, it calculates an efficient driving strategy for engine management and transmission control. By accelerating at the right time in advance of inclines and by avoiding unnecessary gear shifts, fuel consumption can on average be reduced by 3 percent. In the future, Bosch will use topographic navigation data as an electronic horizon for the perfect energy management of hybrid drives. For example, stored energy can be used for additional propulsion on uphill stretches, while excess energy on subsequent downhill gradients can be recovered in order to recharge the battery.
Natural-gas drives also offer lower costs and more climate protection. Natural gas not only costs less at the pump than diesel. Natural-gas drives also emit 15 to 20 percent less carbon dioxide than a comparable diesel engine. Bosch offers two alternative technologies for this alternative fuel: monovalent systems for spark-ignition engines run solely on natural gas, and bivalent systems with both CNG and diesel injection. For the latter variant, Bosch is currently working on customer projects in Brazil. It also sees good opportunities in the United States.
German bonus scheme for early adoption of Euro 6 in trucks
“Environmental and climate protection make economic sense for fleet operators,” Bohr said. For example, Germany is giving tax credits for early procurement of trucks that meet the Euro 6 standard, which comes into force in 2014. At an annual total freeway mileage of 130,000 kilometers, such a truck will cost a good 6,500 euros less in tolls than a Euro 3 truck. Bosch is supporting commercial-vehicle manufacturers with technical solutions where the nitrogen-oxide catalytic converter works with or without exhaust-gas recirculation.
More trucks will need anti-skid and emergency braking systems
Just as with environmental protection, legal requirements for accident prevention are also becoming stricter. The ESP electronic stability program which Bosch was the first to launch, will be mandatory for new vehicles in nearly all classes in Europe at the end of 2014. While anti-skid systems are already fitted in a good 70 percent of new cars throughout Europe, the share of vans equipped with such a system only stands at 60 percent. Bohr sees a need for some catching up here. The new Bosch ESP generation can meet this need, also in light commercial vehicles with large braking systems and high braking pressures.
At the end of 2014, driver assistance systems such as automatic emergency braking are also to become mandatory in Europe for many trucks weighing more than 3.5 metric tons. For this purpose, the Bosch portfolio includes a radar sensor that is designed for speeds up to 150 kph, which makes it suitable for mid-range applications, especially in trucks and vans. This new radar sensor enables a series of functions in addition to emergency braking, such as to the ACC cruise control system. This relieves truckers of some of the burden of driving, and contributes to greater road safety.
