Bauma 2016

Driver’s cab monitors surroundings

Bosch is part of the Bauma 2016 and presents the Genius Cab. Using cameras and environmental sensors, drivers can monitor their surroundings and intuitively control vehicle functions via a display and joystick.

Time is money. That is especially true on construction sites. Maneuvering around the site, unexpected delays caused by excavator and wheel-loader accidents, or breakdowns – all of this costs time and hence money. “We take a machine that weighs several tons and maneuver it with millimeter accuracy, eight hours a day. Even the tiniest detail has to be right,” said the wheel-loader operator Roland Ehrensberger.

That is why, at this year’s Bauma trade show, Bosch presents a driver’s cab developed especially for construction machinery. At this driver workplace of the future, vehicle operating data can be analyzed on a tablet display. Ultrasonic and video sensors monitor the vehicle’s surroundings more thoroughly than a rear-view mirror, which prevents downtimes due to accidents. These surround sensors are an important step in the process of making construction vehicles even safer.

“Bosch is turning construction machinery into technology showpieces,” said Johannes-Jörg Rüger, president of Bosch’s newly founded Commercial Vehicle and Off-Road unit. “The megatrends of automation, electrification, and connectivity don’t stop at the gates of construction sites or mines.” In the future, construction machinery will automatically carry out certain tasks, with drivers scheduling tasks at the connected interface in their cab.

Bosch presents systems solutions for construction machinery for the first time at Bauma 2016. At the start of the year, the supplier of technology and services set up a unit specifically for this field. “As a systems supplier, we want to offer everyone the solution they need,” Rüger said. The unit’s portfolio comprises all Bosch products and services that are relevant for construction machinery: “Modern sensor systems, cameras, and display technology improve the driver’s workplace, as well as increasing safety and hence also productivity,” explained Andrew Allen, head of the unit’s construction business.

Bosch has worked with partners to integrate its products into a futuristic driver’s cab. The newly founded Cab Concept Cluster project brings together a network of renowned suppliers, the Technische Universität Dresden, and VDBUM, the German association for construction, environmental, and machine technology. The project’s aim is to demonstrate the potential of efficient system integration to manufacturers of construction machinery, agricultural machinery, and industrial forklifts. This concept has already notched up its first success: the Genius Cab driver’s cab won the Bauma innovation award in the Design category.

Components of the Bosch driver’s cab

The body computer is the central element in the electronic concept. It reduces the number of electrical connections, relays, and fuses. This not only saves material but also makes circuits less complex, which in turn reduces error rates. The body computer’s programming can be customized to suit each customer’s application. In the Genius Cab, the body computer performs the central control of the sensor and actuator systems via CAN (J1939), LIN, or directly.

The direct wiper drive adjusts to prevailing weather conditions – whether snow, showers, or hard rain. The wiper drive can be adjusted to fit different cabs. Bosch side-view mirror replacement displays give drivers a digital look over their shoulder. Integrating the displays into the vehicle interior means that side-view mirrors become superfluous. Particularly in the working environment of a construction site, reducing blind spots significantly increases workplace safety.

An ultrasonic sensor system can monitor the environment when human eyesight is not enough – when visibility is poor for example, or at night. These sensors give drivers unobstructed all-round vision, which heightens operating safety. The display shows drivers any obstacles, so they can react accordingly. Measurement ranges can be defined individually for each sensor.

The central user interface in the Genius Cab is the DI4-mid display and terminal, which can be operated using buttons or via the touchscreen. With a 7-inch display, the DI4 is programmable using the Codesys Version 3.5 development environment.

Another interface is the 4THE5 joystick. In excavators, this controls functions such as shovel movements. At the same time, the joystick is an important interface to the DI4-mid terminal, since its push buttons can be used to activate terminal functions including the windshield wipers, side-view mirror replacement system, and cab lighting.

"It is interesting that a Tier 1 automotive supplier joins the construction machine business," said Holger Zeltwanger, Managing Director at CAN in Automation. "Bosch, the inventor of the CAN protocol and one of the originators of CANopen, is looking to new markets, which have some similarities with one of its main businesses: the automation of vehicles."

The Bauma 2016 takes place in Munich, Germany from April 11 to 17. You can find Bosch in hall A4 at booth 327.
