Danfoss Power Solutions announced the launch of its PLUS+1® Autonomous Control Library (ACL) 3.2 software for off-highway machinery. PLUS+1 ACL 3.2 consists of new and updated blocks that enhance machine self-guidance capabilities through improved obstacle and hazard detection and environmental landmark identification. 

Danfoss PLUS+1 ACL software comprises preprogrammed and pretested software blocks covering areas such as perception, positioning, and navigation. The software enables users to add autonomous functionality to mobile machinery by integrating the blocks into their machine software applications, eliminating the need to develop software from scratch. Designed for in-house engineering teams at original equipment manufacturers and distributors, PLUS+1 ACL software reduces development time and costs.

PLUS+1 ACL 3.2 includes the following new and updated software blocks:

• Post Detect improves localization by identifying and using rectangular posts around the machine as landmarks, both indoors and outdoors.
• Reflector Detect identifies reflectors in the machine’s surroundings, which can be used to define the machine’s path or improve its location within the environment.
• Projected Path Area creates zones in the machine’s immediate trajectory to better detect obstacles when the machine is turning.
• Obstacle Detect Area enables defined zones to be created around the machine, which can be used to stop or adjust machine motion when an obstacle is detected within these zones.

• Lidar Filter improves performance in foggy and dusty conditions by reducing noise from the incoming lidar signal, providing more accurate and efficient detection capabilities with fewer false positives.

The new and updated ACL 3.2 blocks enhance Level 3 autonomous functionality by helping prevent collisions and improving machine positioning when GPS is not available. Level 3 autonomy introduces automated driving features to mobile machinery, enabling task consistency regardless of operator experience. This improves precision and productivity while enhancing safety.

“Better productivity, safety, and efficiency for end users, along with ease and speed of development for OEMs, is increasing the uptake of autonomous machines. ACL 3.2 delivers on both fronts,” said Adam Khaw, Head of Autonomy, Danfoss Power Solutions. “We will continue to work closely with our customers to enhance this world-class software platform, enabling OEMs to develop and manufacture high-quality machines that set a new benchmark for speed to market.”
