Initial Challenge
Main challenge was the implementation of the system behaviour, considering not only electronics but also mechanics, while keeping safe and reliable movements.
The development of this product was a compromise between the speed and torque of the motors to keep the system safe and reliable. Meeting customer expectations for speed and positioning needs consideration of friction force and motor synchronization, keeping detection of anti-pinch requirements while avoiding false reversals.
- Development according to ISO 26262 ASIL A
Proposed Solution
Motor synchronization via CAN communication, adaptable electronics to different mechanical profiles and software architecture with specific diagnostic capabilities.
It was key for the development to perform an extensive analysis of different mechanical profiles recorded by the electronics in order to achieve stable movements. Ensuring a stable production of the mechanics, as well as an adaptable software during the entire life of the product was also very helpful.
Results and Achieved Benefits
- Series production of adaptable control units integrated with mechanics and motors
- Project finished on time, budget and under specification of the safety and quality standards
- Specific Know-How of innovative mechatronics solution
Lessons Learned and Best Practices
- Continuous communication with customer is key to provide the product needed on time.
- Testing and continuous adaptation in different environments and levels improves reliability.
- Keeping documentation simple and efficient avoids overengineering, allowing more time for implementation and testing.
