Glossary

Acceleration Slip Regulation (ASR):The ASR prevents wheelspin when driving away on a slippery surface. It provides no more power than the drive wheels are able to transfer to the road surface. Wheelspin by one wheel - e.g. on an icy roadside - is prevented by metered braking.

AEBS (Advanced Emergency Braking System) and Lane Assist (SPA):Most accidents begin long before a collision: for example, with poor visibility or unforeseen hazards. While the SPA warns the driver - by means of seat vibration - of an unin-tended crossing of the lane markings, the AEBS reduces the danger of driving into slow-moving vehicles or stationary ob-stacles ahead. If danger threatens, it initiates partial and full braking as part of an ascending scale of warnings, so as to avoid a rear-end collision or to reduce damage in the event of an accident. It therefore reliably complies with the Euro-pean regulations on automatic emergency braking.

Anti-lock Braking System (ABS):The braking forces acting on the individual wheels are dis-tributed by the ABS so that even in an emergency braking situation no wheel is blocked for any length of time and the steering control of the bus is largely maintained.

BlueEfficiency Power:In developing the new BlueEfficiency Power engine genera-tion, Mercedes-Benz has broken new ground. The goal was to develop a new engine that meets the Euro VI standard and is future-proof without increasing fuel consumption at a high output.

Mercedes-Benz had already done development to meet earli-er standards for emission technologies. In order to meet the stringent requirements of the new standard, the following technologies are now used in combination:• Cooled on-demand exhaust gas recirculation (EGR)• Diesel particulate filter (DPF)• SCR technology

Another major goal in the development of the new engine generation beside compliance with Euro VI was economy. That primarily means a low fuel consumption. In coach oper-ations, levels as for Euro V are achieved or even bettered. In addition, the developers have concentrated on low main-tenance costs. As a result, the maintenance intervals for the OM 470 in coach operations have been extended by up to 30 %, in comparison with the predecessor engines.

Another factor affecting economy is the long life and reliabil-ity of the engine. To ensure this, the engines have been test-ed worldwide under the toughest conditions. Up to now, the engines have covered more than 60 million kilometres in en-durance tests on test stands and in the field – never before has an engine been so intensively tested.

BlueTec 6®:The new exhaust emission standard Euro VI requires a further drastic lowering of emissions. To meet these requirements, as part of the introduction of BlueEfficiency Power, a completely new generation of engines and exhaust after-treatment sys-tems with the designation BlueTec® 6 is being launched. With this new development, Mercedes-Benz is continuing the tradi-tion as a pioneer in environmental protection.

The provisions of the new emission standard demand a reduction of 66 % for particulate emissions; in the case of nitrogen oxide levels, a reduction of 80 % compared with Euro V must be realised. Earlier Euro standards were achieved with the following exhaust emission technologies: exhaust gas recirculation or BlueTec® engine technology comprising a highly efficient engine and SCR system with or without a diesel particulate filter.

15

In order to meet the required Euro VI levels, a complex sys-tem of emission control is necessary for the engines. The three proven technologies are now brought together in a matched system optimised for fuel economy.

Coupling new engines and complex after-treatment with dif-ferent drive train combinations and vehicle concepts in the construction of buses of different heights and lengths ne-cessitates making complex changes in the vehicle body. Next to the greatest possible environmental compatibility, the primary aims of the development of the new engine gen-eration included economic aspects like low lifecycle costs. That means first and foremost a low fuel consumption. In coach operations, this is at the level of Euro V or even lower for the new engine.

With an eye on saving resources, environmental aspects and rising diesel fuel prices worldwide, the Mercedes-Benz de-velopment engineers have succeeded in achieving a mile-stone in engine development with the BlueEfficiency Power engines.

Brake Assist (BAS):The BAS electronics are able to detect emergency braking situations and automatically build up maximum braking pow-er within fractions of a second. This significantly shortens the stopping distance of the bus.

Cataphoretic dip priming (KTL in German):Cataphoretic dip priming is an electro-chemical process for coating the complete body shell in an immersion bath. It is ideal for painting intricate structures and large numbers of units. Water-based paint protects the bus so perfectly against corrosion because the paint coat is applied to every part of the body. Currently, cataphoretic dip priming is demonstrably the best protection available against corrosion in vehicle construction.

Electronic level control:Passengers and luggage are not always evenly distributed in the vehicle. As a result, the height of the vehicle varies from wheel to wheel. The electronic level control automatically regulates the vehicle height at each wheel so that the step height is always the same.

Electro-pneumatic braking system (EBS):As a further development of the conventional air brake, the electro-pneumatic braking system offers numerous advantages. When braking, the control unit first activates the retarder. If greater deceleration is required, the control unit uses the information in the data network to determine the optimum braking pressure for each axle. The elec-tro-pneumatic braking system thus enables much shorter stopping distances and significantly less brake disc and lin-ing wear.

Electronic Stability Program (ESP®):In situations where the driving dynamics are critical, ESP® selectively controls engine output and the braking forces on each wheel individually. Within the boundaries of the physi-cal laws, finely regulating the braking of the vehicle in this way prevents any possible “breakaway“ by the bus. ESP® therefore contributes noticeably to a reduction in the ten-dency to understeer and the risk of skidding during corner-ing or evasive manoeuvres.

Important for you. Important for us. Technical data stored in the vehicle. Electronic vehicle components (e.g. Airbag Control Unit, Engine Control Unit) contain data storage for vehicle Technical Data, including but not limited to Diagnostic Trouble Codes in the event of a malfunction, vehicle speed, braking force, or operating conditions of the Restraint System and Driver Assistance Systems in case of an accident (no audio and no video data recording). This data is either stored volatile, punctual as snapshot e.g. Diagnostic Trouble Codes, over a short period of time (a few seconds only) e.g. in case of an accident or in aggregated form e.g. for component load evaluation. The data can be read using interfaces connected to the vehicle. Trained technicians can process and utilize the data to diagnose and repair possible malfunctions. The manufacturer can use the data to analyze and improve vehicle functions. When requested by the customer, Technical Data can form the basis of additional optional services. In general, data from the vehicle is transferred to the manufacturer or a third party only according to legal allowance, or based on a contractual customer consent in accordance with data protection laws. Further information regarding storage of vehicle Technical Data is provided in the vehicle Owner’s Manual. Mercedes-Benz Buses and Coaches naturally handles customer data confidentially.
