Accelerated vehicle development
software

Cloud-native simulation platform

VI-grade's
(Darmstadt,
Germany) VIWorldSim is a highresolution graphic
environment for
accelerated vehicle
development dedicated to the highend automotive market. The software features a user-friendly and fully integrated
graphic environment on VI-grade driving simulators with realistic traffic and sensor behavior. The software not only brings
traditional track modeling to a higher level of realism based on
the Unreal high-performance graphic engine but also adds the
features needed to test on CAV (connected and autonomous
vehicles) sites, urban environments, and public roads for ADAS
and autonomous vehicle (AV) testing. Features include traffic,
pedestrian, lighting, weather and sensors to enable users to
create and test scenarios for vehicle development programs
through an intuitive and easy-to-use desktop editor. Cars, pedestrians, and animals are AI-driven actors who follow normal
routes or can be controlled through the definition of specific
behaviors. A single engine provides users with different types
of environments, simulations and disciplines. 

OnScale Solve from
OnScale (Silicon
Valley, Calif.) is a
SaaS (software as a
service) engineering
simulation platform
that combines powerful multiphysics
solvers with massively scalable cloud supercomputers from AWS and Google
Cloud. OnScale Solve does not require any installation and
can be accessed via a secure web-based connection to any
web browser. It features fast multiphysics solvers, automation of time-consuming tasks such as CAD repair and meshing, scalable cloud supercomputer infrastructure, intuitive
UI/UX and integrated workflows, insightful results, and integration with Jupyter notebooks and Cloud AI tools.
According to the company, OnScale Solve overcomes the
limitations imposed by legacy FEA desktop simulation tools,
enabling engineers to run large simulations and parametric
sweeps while enjoying a flexible and fair pay-as-you-simulate subscription model. With this release users can perform
mechanical, thermal and coupled thermal-mechanical analysis. The OnScale Solve roadmap includes the development
of dynamic mechanical, nonlinear mechanics, thermal-fluid,
FSI, and acoustic analysis.

Thermal circuit breaker

Brushless DC motor driver

The new thermal circuit breaker series
from SCHURTER (Santa Rosa, Calif.) features a modern sculpted rocker switch
and bezel, while offering several contemporary color choices. SCHURTER's
TA36 provides what the company says
are seven " trendy " actuator colors and
three bezel colors, which can be mixed or matched. A selection
of five different markings in black, white or embossed complement the offering. The new TA36 family functions as an appliance switch and thermal overcurrent protection device. The
company series offers one-pole switch with overcurrent protection and two-pole switch with one- or two-pole overcurrent
protection. There are 31 different rated currents 0.05 A to 20 A.
Operating temperature range is -30°C to +60°C (-22°F to
140°F). Especially suited for 277 VAC LED lighting applications
in the U.S., other applications for the TA36 include industrial
appliances, HVAC, tools and construction equipment.

Texas Instruments' (TI; Dallas, Texas)
DRV3255-Q1 is a highly integrated Grade
0 brushless DC (BLDC) motor driver for
48-V high-power motor control systems,
such as traction inverters and starter
generators in mild hybrid electric vehicles (MHEVs). According to TI, the
DRV3255-Q1 is the industry's first three-phase, 48-V BLDC motor
driver to integrate high- and low-side active short-circuit logic
that eliminates external transistors and control logic. Meeting the
most stringent safety requirements, the motor driver was designed according to TI's TÜV SÜD-certified functional safety development process, helping enable up to Automotive Safety
Integrity Level (ASIL) D. The TI functional safety-compliant
DRV3255-Q1 allows manufacturers to design a motor-drive system to help enable MHEV systems up to ASIL D, supplying as
much as 30 kW of motor power, which can improve the response time of a 48-V motor-drive system in heavy vehicles.
