According to a study by the German employers’ liability insurance association for the wood and metal industries (BGHW), personal injuries occur most often when vehicles, like forklifts, are backing up in a small space of one to three meters. In Germany alone, official reports estimate the number of accidents involving forklifts at some 12,000 each year. “A driver’s eyes cannot be everywhere at once—that’s where the Bosch multi-camera system comes in,” said Andrew Allen, responsible for Bosch’s Commercial Vehicle and Off-Road unit.
Using the sight assist, the multi-camera system can provide a full 360° view around the forklift—even if it is carrying bulky freight. This simplifies the task of picking up and moving loads, even in tight spaces. The system helps the forklift maneuver with precision and makes it possible to estimate distances more accurately while on the move.
The multi-camera system consists of a control unit plus four compact near-range cameras. Working together, they can capture an area measuring 8 x 8 m. The cameras were originally designed for Bosch’s passenger-car segment but have now been adapted for the special needs of the logistics market.
Cameras are positioned at the front, rear, and each side of the vehicle. With an aperture of nearly 190°, they capture the vehicle’s entire surroundings. Drivers see a realistic representation of their vehicle as a detailed 3D model on a display. As the vehicle moves, the display adjusts the view of its surroundings in real time. To better suit the vehicle’s purpose, the manufacturer can preconfigure the screen to display individual or 360° views as well as full-screen or split-screen views. The driver then can choose the best view for the task at hand from the preprogrammed options.
The multi-camera system can visually project the vehicle’s immediate path over the forward, rear, or top view. To achieve this, the control unit measures the steering angle, calculates the resulting route, and shows it on the display. If the steering angle changes, the system recalculates the route and adapts the display accordingly. The route overlay serves primarily to aid in maneuvering and merging.
