Vehicle dynamics controls are responsible for providing support in difficult driving conditions, as well as achieving an OEM-tailored driving experience and offering advanced driver-assistant systems (ADAS). Components and systems which must be actively controlled include:
Leverage rapid control prototyping or ECU bypassing to execute, iterate, calibrate, and test new control designs in real time without being dependent on old or constrained controller hardware. When the production-level ECU is ready, hardware-in-the-loop simulation enables the testing of controllers by emulating the vehicle in real time.
“With limited resources as a start-up, the time to get things working is really key. Speedgoat excelled for us." Zack Anderson, ClearMotion

Develop new designs for supporting functions such as hill start and ascent, brake assist or crosswind stabilization. Develop real-time and deterministic motion controls needed for lane-keeping assist (LKA), automatic cruise control (ACC), lane-changing assist (LCA), and more.
Frequently Used I/O Interfaces
Simulink® Application Resources
Design and test new control algorithms, including electronic stability control (ESP), anti-lock braking system (ABS) and traction control system (TCS), and improve the stability and safety of the vehicle.
Design control strategies for steer-, shift-, brake- and throttle-by-wire systems. Customize the driving experience to match the overall vehicle-DNA and provide an unique driving experience. Tune designs directly in the vehicle.
Iterate and validate controls for active and semi-active suspension systems to adapt to different driving conditions, improve handling and increase the vehicle's overall safety. Receive real-time inputs from the steering wheel and the breaking and acceleration pedals or emulate them during the ECU testing.
Design controls for complex hydraulic systems needed in construction machinery. Leverage rapid control prototyping to test and tune control algorithms of the hydraulic systems and optimize them prior to integrating into the ECU. Ensure that all requirements are met by testing the ECU safely using Hardware-in-the-Loop simulation and identify/eliminate any last design flaws.
