Tesla Semi regains control after sliding on ice using VDC system
Dan Priestley, Tesla Semi program lead, shared a video showing the electric truck maintaining its line on ice thanks to its Vehicle Dynamics Control (VDC) system. This system, based on high-resolution sensors and precise controls of an 800 kW tri-motor drivetrain, modulates torque and applies selective braking to stabilize the vehicle even with heavy load. The ability to instantly adjust torque at each wheel outperforms hydraulic systems in diesel trucks, reducing risks of skidding and rollovers. Although the video is a Tesla demonstration, it confirms concrete technical advantages in stabilit
- Tesla Semi uses an 800 kW tri-motor drivetrain producing 1,072 hp
- VDC system controls torque and braking at each wheel for stability
🔎 Why it matters: The Tesla Semi's Vehicle Dynamics Control (VDC) system with independent torque control on rear wheels improves stability on slippery surfaces.
📈 Upside: Instant and granular torque control allows correcting slides before they become skids.
📉 Risk: The video is an internal demonstration and does not replace independent safety data or official testing.
