About Adams2021.1 Release

Adams 2021.1 provides features that supports new domains for exploration such as electric vehicle modeling and tools for improved user productivity.

Note: With a continued focus on, enabling simulation-based insight for systems design; Adams has moved to a quarterly release cadence. Customers can now benefit from more frequent updates throughout the year.

Adams 2021.1 Release Highlights

Some main highlights of the Adams 2021.1 include:

  • Independent Throttle and Brake Controls

What is it?

  • Users can now select different throttle and brake control methods for the driving machine.
  • To accomplish this, you can use a machine-controlled throttle (utilizing an engine map that can produce enough negative 'regenerative' torque) and open-loop braking with function set to zero.

What’s in it for you?

  • Better support hybrid and electrical vehicles which may control both throttle and braking signals using a single actuator.
  • You can also study open-loop braking while at the same time using a machine controlled throttle to maintain the requested acceleration.

  • Frequency Response Event’s Report

What is it?

  • The Frequency Response event is an open loop event with sinusoidal steering input where frequency is increased over time.
  • The goal of a frequency response analysis is to provide steering input that spans the entire frequency range of a human driver, roughly 0 to 3 Hz.
  • The report for the frequency response event has been enhanced this release to provide more details than previously. This includes the addition of sections on Lateral Acceleration Parameters, Roll Parameters, Yaw Rate Parameters, and Body-on-Chassis Roll Parameters.

What’s in it for you?

  • More insight form the frequency response event on vehicle behavior that will enable better design decisions.

 

  • Kinetic Energy and Momentum Functions

What is it?

  • New functions for the recovery of system kinetic energy, translational momentum and angular momentum have been added for use in creating requests.

What’s in it for you?

  • More design information and insight from your Adams runs
