Programmable Controller for Mobile Machines with CAN-Bus

From STW Technic
 

 
The importance of electronic controllers for use in mobile machines continues to increase. The industrial demand for more powerful and efficient machines with improved safety and comfort is large, and this, combined with the simultaneous pressure to optimize manufacturing costs, is driving the evolution towards electronic control solutions. In modern "special purpose" vehicles various systems are automated efficiently with electronic controllers. These include electronic-hydraulic steering systems, hydrostatic vehicle drive regulators with automatic braking system (ABS) or anti-slip regulation (ASR), engine management (speed regulation), transmission/gear control, and complete task specific hydraulic control of a mobile machine (earth moving equipment, construction equipment, service vehicles, public utilities vehicles, etc.). An important consideration in many applications is the interaction between the electronic controller and hydraulic valves. Equipment manufacturers, using modern micro controller technology and regulation algorithms with a high dynamic response, achieve very sensitive control of hydraulic valves. Thus vehicles and loads weighing many tons can be moved and positioned with millimeter accuracy!
