Control units, or ECUs, are very diverse. They are often distinguished by their varied functions and types, as well as their number of electrical inputs and outputs. However, they all have one thing in common: they have to undergo testing. They have to prove their functionality and safety in individual module tests and in the ECU network. To this end, Hydrive Engineering has invested in even better equipment.
To cope with the wide range of ECUs, Hydrive Engineering uses modular, quickly expandable modules to simulate and measure ECU interfaces, and has only recently extended its own hardware collection. In addition, real-time computer performance was enhanced so that detailed and complex machine models can also be used. It is now possible to simulate hydraulics in a 2D or 3D mechanism.
This enables Hydrive Engineering to test all ECUs – from standard units to more specialised ECUs – in-house. Customers for whom owning their own test rig is not worthwhile can comfortably carry out all tests at Hydrive Engineering, and will receive the test report the very next day.ECUs (engine control units, not to be confused with electronic control units) are computers that are specifically developed to control, regulate and monitor engine functions.
Modern combustion engines are equipped with an electronic throttle body and an air-flow sensor which regulate the air mass, mixture ratio (air to fuel), catalytic exhaust gas treatment and recirculation as well as, using a variable valve train, the opening and closing angles of the inlet and exhaust valves, according to the current requirements. The boost pressure can also be regulated in engines with suitable charge. ECUs are used in automotive engines and are increasingly emerging in construction, agricultural and factory machines.
Since 2005, Hydrive Engineering has supported manufacturers of cars and construction machines in the development of drive components and control software.
Basic research ensures that the latest findings, methods and tools are passed on and used in industry.
