Bauma 2019

Making drivers’ cabs digital

At the Bauma 2019, Continental showcases a range of CAN-based solutions for machine operators. For example, the presented camera system increases driver comfort and safety in construction and mining vehicles.

Continental sees digitalization and connectivity in construction vehicles as a crucial factor for the future of the industry. The technology company focuses on the human being – the stress level of the driver, for example, must be reduced, and it must be possible for them to handle the flood of information in such a way to maximize efficiency and safety. That’s why Continental is developing digital solutions such as the Proviu 360 surround view system. The digital camera system is shown at Continental’s Bauma 2019 booth from April 8 to 14 in Munich, Germany in hall C5, booth 403.

“As technical development progresses, construction machine operators are receiving more and more new information – and it’s valuable information too, because it increases efficiency and quality on the construction site,” said Peter Wagner, the Continental segment manager who is responsible for small series and retrofit solutions in the construction machinery sector. “However, it’s the drivers who have to deal with this flood of information, and if we really want the new digital developments to lead to more efficiency and safety, then we have to make it as easy as possible for them by displaying that information in a clear and targeted way.”

The Proviu 360 camera system has four 1,3-megapixel cameras covering every direction, giving the driver a bird’s eye view of his machine. Compared to its predecessor, this second generation of the camera is completely digital, enabling the system to deliver sharper and higher quality images in HD resolution to a 10-inch HD touch display. Production of the Proviu 360 digital version as a general application for a bird’s-eye view is planned for 2020. Many other special fields of application can also be based on the camera system, such as precise edge control during rolling operations.

The product can also become “intelligent” with the next step, because valuable additional information like radar data and tire pressure can be fed into the system. In augmented reality, markers, icons, or texts can also be placed on the camera image and seen in the display – the sensors can warn of collisions, for example, and this can be shown on the screen in colorful 3D imagery. Accidents with persons and damage to the machines can be prevented thanks to this comprehensive view of the vehicle’s surroundings.

Sensor fusion

“We deliberately opted for the universal CAN bus interface already established in the market, because it allows a wide range of possible applications. Our CAN bus management lets us filter the stream of data and provide only the information that the driver needs,” said Daniel Wappler, Product Manager at Continental. The combination of different sensor data, that Proviu 360 will offer in the future also increases the quality of the information, said the company. This is especially true for the fusion of data from camera and radar.

Digital displays

Displays are also among the components Continental uses to contribute to greater efficiency in controlling construction machines. Combining ruggedness with bright imagery that makes the screens easy to read even in strong sunlight, these displays are tailored to operating conditions on the construction site. For example Multiviu Compact primary instrumentation with 7-inch display and optional touchscreen: An optional built-in Bluetooth module lets the driver retrieve vehicle information like oil or fuel levels with their mobile phone and forward the information to the site office. Conversely, the display can also show messages from the smartphone. Two CAN ports, a video input, and multiple digital and analog inputs and outputs round off the technical features. Continental also offers the Multiviu Compact with a 4,3-inch display as an entry-level version.

In addition to these solutions, the company also offers premium versions, like the freely programmable Multiviu Professional12 instrument cluster, which boasts a high-resolution, optically bonded 12,3-inch color TFT display, a real-time 2D graphic display, and a video display. It eases the driver’s workload by presenting all the relevant information about their machine as animated text, scales, bar graphs, or symbols. Continental uses the cluster in the modular driver’s workplace (mDWP).

The mDWP can be as individual as the needs of its users. One special feature is the combination of up to three displays with two freely configurable control panels, making all the relevant information and the most important control panels to see. The driver benefits from this concept because he only sees the information that he really needs for the task at hand, so he’s not unnecessarily distracted and can concentrate on driving and his work processes. Pop-up messages can also be displayed to warn the driver of unusual or hazardous situations.

For the manufacturer, the modular driver’s workplace represents a major step forward in terms of flexibility and individualization. Due to its modular design, control panels, and displays can be arranged to match the manufacturer’s requirements, allowing the company to focus entirely on the special requirements of its customers. Operator panels are connected via CAN network and are freely programmable, making the system universally usable. Due to the robust design of all its components, the mDWP also proves its worth in the tough everyday conditions that prevail on construction sites.
