For example, the Dynamic Tilt algorithm supplied by ACEINNA with the VG_AHRS application could be performance enhanced by listening to messages such as Odometer or Vehicle Speed to better compensate for the influence of linear acceleration on dynamic roll and pitch. This can include for example, LIDAR, Camera, Radar as well as primary compute engines all benefitting from one centrally mounted high-performance IMU on the vehicle.Ī CAN bus based OpenIMU300RI application can also listen to other messages on the bus. Some of our customers report using CAN bus to share IMU data with up to 20 other vehicle subsystems in parallel. In an autonomous vehicle CAN is used to pass IMU data to other sensors as well as the main vehicle control i.e., the vehicle’s brain. So Why Create a Custom IMU App with CAN Bus? The OpenIMU CPU can run both standard and custom algorithms created using ACEINNA’s free, open-source developer tool-chain. The OpenIMU300RI is a 9-axis MEMS-based IMU that includes a CAN-interface, a RS-232 interface, and an ARM Coretex M4 CPU. OpenIMU3ooRI CAN Bus IMU with Open Source Communication and Navigation Stack
