press release

At the Agritechnica, the world's largest trade fair for agricultural engineering, which takes place from November 12 to 16, 2013, Bosch presents innovative technical highlights for use in off-highway vehicles. Integrated into a new Fendt tractor series, an innovative wiper direct drive goes into production. Not needing any linkage, the drive allows a wiping angle of up to 320 degrees. Another novelty at the Bosch stand in Hall 3, stand 06, is the electric energy management. Optimizing the generation as well as the consumption of energy by means of electric consumers, it reduces the latter. Among other functions, the system permanently controls the battery charge level increasing its reliability and service life. At the same time, both fuel consumption and CO2 emissions are reduced. In this manner, the system also helps to comply with new emission limit values. A third novelty is the brushless and particularly efficient auxiliary water pump for auxiliary cooling circuits and a flow rate of 1,200 liters per hour at a pressure of 0.6 bar.

Electronically Controlled Wiper Direct Drive
The new Bosch direct drive for windshield wipers is considerably smaller than conventional wiper drives with links. Each arm is driven by a drive for its own and mounted directly onto the motor shaft. The electronic control system synchronizes both of the drive units. Sensors integrated into the wiper drive detect the actual position of wiper arms. This allows the safe operation – even with reverse-rotation systems covering large wiping areas. Thanks to the high sensitivity of the drive motor to resistances, it can, for instance, recognize the amount of rain falling onto the windshield and then adjust the wiping cycle appropriately. The extreme case is a bank of snow, which automatically reduces the wiping area and thus protects the drive against overloads.

The new direct-drive units are of identical construction for any vehicle window. Settings such as the wiping angle or the parking position are individually programmed by means of software once the assembly is finished. This simplifies logistics and storage for manufacturers of off-highway vehicles and agricultural-machinery workshops.

Intelligent Load Distribution through Electric Energy Management
Agricultural-vehicle batteries have to withstand long seasonal idle times and yet they are to provide high starting power and to have enough resources for supplementary equipment such as, for instance, an air-conditioning system. Therefore, Bosch offers a comprehensive range of maintenance-free and extremely reliable batteries for off-highway vehicles in particular. Moreover, Bosch's new electric energy management ensures an intelligent load distribution and controls the increasing number of electric consumers. The main component is the Electronic Battery Sensor (EBS), which is installed into the battery terminal bay. In an extremely precise and dynamic manner, it measures the following battery values: current, voltage and temperature. The EBS-integrated software analyzing the battery charge level determines the current and the projected battery condition. As a consequence, the charging process can be optimized preventing deep discharge. The system can be adjusted to the different requirements of different vehicles. This allows a flexible use for all kinds of vehicles.
In addition, the Body Computer Module, the central comfort control unit, controls the increasing number of both electric consumers and additional functions. Having its origin in large-scale production, it is flexible in terms of usage and can easily be adjusted to the specific requirements of the vehicle. The big advantages are the cost reduction through custom configuration, optimized cable harnesses and shorter development times.

New Auxiliary Water Pump with High Efficiency
Bosch engineers specifically developed the new coolant pump PCE-L for the assembly at auxiliary cooling circuits. This includes, for instance, indirect charge-air cooling, cooling of power electronics or the application at electric or hybrid drive trains. The pump is powered by a brushless DC motor with a very high level of efficiency. The compact design, the low weight and the service life – which has been significantly increased in comparison to previous models – of more than 12,000 hours of operation lead to reduced fuel consumption and consequently to lowered CO2 emissions. Furthermore, the new coolant pump runs extremely quiet and thus even overachieves the high requirements imposed by vehicle manufacturers and users. An internal diagnostic function records malfunctions, such as exceeding the limit temperatures or a blocked pump, and reports them to the control unit. If the fault is not removed after a while, the pump automatically runs the emergency mode with reduced performance, but maintains the cooling function at the same time.

The Automotive Aftermarket division (AA) provides the aftermarket and repair shops worldwide with a complete range of diagnostic and repair shop equipment and a wide range of spare parts – from new and exchange parts to repair solutions – for passenger cars and commercial vehicles. Its product portfolio includes products made as Bosch original equipment, as well as aftermarket products and services developed and manufactured in-house. More than 18,000 associates in 150 countries, as well as a global logistics network, ensure that some 650,000 different spare parts reach customers quickly and on time. In its “Automotive Service Solutions” operations, AA supplies testing and repair-shop technology, diagnostic software, service training, and information services.
