Next generation of mobile electronics is ready

Rexroth RC5-6/40 controller and Rexroth PR4 pressure sensor with SENT interface

Controllers and sensors with SENT interface from Bosch Rexroth meet the increased demands for accuracy, availability and security when it comes to mobile machines.

At Agritechnica 2017, Bosch Rexroth will unveil the next generation of controllers for mobile working machines developed jointly with Bosch. It combines proven features, such as free programmability with a new hardware architecture and a future-proof software concept. Developed to meet more demanding system requirements, Bosch Rexroth is developing sensors with SENT interface at the same time, which in addition to all measured values also transmit condition data to the controller. The first controllers as well as the SENT sensors will go into series production as early as 2018.

Within the framework of the new Bosch electric/electronic (E/E) architecture for commercial vehicles and mobile working machines, Bosch Rexroth is currently developing a new series of controllers. In addition to advanced multi-core processors, it uses new ASICs for flexible I/O connections, as well as a variety of interfaces such as SENT (SAE J2716™), CAN FD (Flexible Data Rate) and Ethernet BroadR-Reach® (100Base-T1). The ISOBUS (ISO 11783) Physical Layer also belongs to the range of interfaces. The new scalable Bosch Rexroth hardware platform offers the user pin-compatible controllers in several configuration levels in order to select the appropriate controller depending on the particular application.

Even if, "under the hood", the new generation of controllers uses tried-and-tested basic software for all necessary processes according to the AUTOSAR automotive standard, the user can still count on simple programming according to IEC 61131-3 or in C language. This is achieved by means of an uncomplicated application programming interface (API). The application programmer therefore gets the opportunity to develop software modules that are interaction-free based on multi-core technology and to efficiently bring any necessary changes into series production at a later date.

The new generation also takes account of increasing demands in terms of machine safety and data security. It supports the feedback-free design of functional safety up to Performance Level d according to EN ISO 13849-1, as well as up to Agricultural Performance Level d according to ISO 25119. Integrated hardware encryption modules protect against attacks on the data integrity of the vehicle.

The increasing incorporation of functions in the software often places even higher demands on the availability and accuracy of sensor data. That's why Bosch Rexroth equips sensors for mobile working machines with the SENT interface, which is already widely used in the automotive industry. The values from several sensor elements can be transmitted digitally and securely via a single data line without being subjected to electromagnetic interference, which is the case with analog interfaces. The accuracy of the measurement is dependent only on the sensor and not the controller. In addition to the actual measurement data, SENT sensors also provide more information on the sensor as well as diagnostic data. In this way, the controller receives important status information, which in turn increases the availability of the machine. Starting with the PR4 pressure sensor for pressures up to 280 bar, Bosch Rexroth will be offering an ever-increasing number of sensors with a SENT interface in the next few years.

Economical, precise, safe, and energy efficient: drive and control technology from Bosch Rexroth moves machines and systems of any size. The company bundles global application experience in the market segments of Mobile Applications, Machinery Applications and Engineering, and Factory Automation to develop innovative components as well as tailored system solutions and services. Bosch Rexroth offers its customers hydraulics, electric drives and controls, gear technology, and linear motion and assembly technology all from one source. With locations in over 80 countries, more than 29,500 associates generated sales revenue of approximately 5 billion euros in 2016.

Greater availability of agricultural and forestry machinery thanks to smart servicing

As part of the electronification of mobile hydraulics, Bosch Rexroth is developing new, data-based services for all aspects of mobile working machines. The PredictDrivetrain service from Bosch Rexroth detects wear using operating and sensor data and is able to determine the remaining service life. Thus, downtimes for tractors, combine harvesters and other agricultural and forestry machinery in the field can be avoided without the conventional, pre-scheduled preventive maintenance intervals. The lean determination of operating data also serves as a basis for the application-oriented design of mechanical components using the NextGenSpec app without the danger of undersizing or oversizing. For the assembly of new vehicles, CalibrateHydraulics significantly reduces the commissioning effort with the online transfer of test bench data for components to the OEM.
