AI Technical Summary
Existing drive-by-wire pedal systems suffer from insufficient design of single or redundant sensors, which may lead to loss or error of pedal signals when sensors fail, affecting driving safety and making it difficult to meet high-level functional safety requirements. In particular, the system's stability and fault tolerance are insufficient in the face of complex electromagnetic interference and electrical faults.
The system employs a combination of Hall effect sensors and inductive sensors, and utilizes a fully isolated architecture design, with these sensors positioned at the top and bottom of the pedal respectively. Two independent SENT digital signals are output for cross-verification, ensuring system redundancy and reliability and meeting ASIL D level functional safety requirements.
It achieves high reliability and redundancy in pedal displacement detection, with a displacement error of ≤0.1%, significantly improving the safety and stability of automotive drive-by-wire pedal systems, reducing safety risks caused by sensor failures, and meeting high-level functional safety requirements.
