In this pilot activity originally we aimed to develop and validate solutions for next-gen inverters and BMSs for EVs. Based on the implemented pilot activities our focus turned to the electronic stability program (ESP) and the electronic control unit (ECU).
Why are they significant? The ESP supports the driver in nearly all critical driving situations. It comprises the functions of the antilock braking system (ABS) and the traction control system, but can do considerably more. It detects vehicle skidding movements, and actively counteracts them. This considerably improves driving safety.
While the ECU, also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in various motor vehicles being one of the key component.
In this pilot our aim is to advance the eco-design of an ECU, which is used for the management of the ESP. The ESP makes a significant contribution to road safety by preventing vehicles from skidding, thus helping to prevent accidents and save lives. Due to a wide variety of powertrain technologies and degrees of automation, braking systems in vehicles are subject to fundamental changes and must be flexible and modular. Vehicle manufacturers strive for personalization and differentiation, for example through driving dynamics and driving experience. This kind of product is mounted millionfold in cars all over the world.
Activities:
- PHASE 1 Implementation – Task 4.1.1 Implementation of pilot #1
- PHASE 2 Validation – Task 4.2.2 Validation of pilot #1
To learn more about the product, the obstacles and failures toward the development of a sustainable product (e.g. a product that can be repaired, reused and recycled) must be assessed through a set of sustainable indicators (KPIs). At the end, the ESP use case will get its own sustainable passport. The main objectives of the ESP use case are as follows:
- Extend use phase (repairability): change the product design for a better disassemble and reassemble, and for a better access to surface mounted parts on the PCB (back and topside level).
- End of life (recyclability): change the product design of housing and PCB for a better dismantling. (In best case with standard tooling of dismantler and workshops).
- Manufacturing (material replacements): identify possibilities to replace material by recycled material in the product and find possibilities to lower manufacture energy by use of new materials.
