AUTONOMOUS FEATURE
performance, Angle Random Walk (ARW) and Bias Instability (BI),
were improved by a factor of three.
The lower the ARW number, the less error there is during the integration
of the rate signals used to calculate attitude and position. BI is
a measure of how much the gyro bias drifts with time. Improved BI
enables quicker and better estimation of true gyro bias and results in
more accurate attitude and position estimations.
The MTLT335D module's system wiring harness and SAE J1939
CAN interface messages are the same as the previous-generation
MTLT305D. Keeping these the same allows the system to use the
same software to decode measurement messages, largely preserving
system software compatibility. By making migration to ISO 13849
straightforward, OEMs and farm equipment manufacturers can improve
their solutions without requiring significant redesign.
Where is farming going next?
" Anywhere it wants " is the glib answer to that question. With just a
cursory look at today's agriculture, that answer doesn't seem far from
the truth. Look at what agriculture is achieving as advanced technologies
become more affordable, adaptable and agile. Terrain once
too uneven to be considered arable is being conquered with sensors
that calculate and correct a tractor's roll, pitch and yaw.
Autonomy is freeing farmers from the tedium of tractor guidance and

BATTERY-ELECTRIC SOLUTIONS
Thursday, September 15, 2022 at 12:00 pm U.S. EDT
Speakers:
This 60-minute Webinar from the editors of Truck and Off-Highway Engineering will discuss
equipment manufacturers and supplier's latest engineering efforts to bring reliable electric
machines to construction sites as well as advanced technologies to improve uptime and
maintenance of EV systems.
Topics include:
* The challenges of providing comprehensive, real-time performance, including FPGA-based
hardware acceleration for the development and testing of power electronics and
electric-drive controls.
* The challenges of supporting a range of application-specific interfaces and protocols for
electric motors, fuel cells, batteries, power electronics and charging systems.
* Open libraries with open and ready-to-use models that can be executed on processors
or FPGAs to speed-up the development process.
