This reference design provides hardware architecture for a Park Assist System (PAS) using three highly integrated, system-on-chip (SoC) ultrasonic transducer drivers. These ultrasonic transducer drivers have an integrated signal conditioner with an advanced digital signal processor (DSP) core. Using these integrated features, object detection from 25cm to 2.5m is achieved. The distance data is sent over a one-wire interface (OWI) to a local electronics control unit (ECU) where the data can be aggregated and processed. The sensor initialization, object detection algorithm, and software described in this design guide provide a basic framework to help engineers working on PAS for automotive or collision avoidance.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
