Texas Instruments PGA460-Q1 Manual

TI Designs: TIDA-01597
Automotive Ultrasonic Sensing Module Reference Design
for Park Assist
Description
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 25 cm to 2.5 m 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.
