Brake Force Build-Up: Why AEB Stopping Distance Beats the Textbook Formula (2D Model)

Interactive 2D bird's-eye AEB simulator: a genuinely distinct model from the 3D version — braking deceleration ramps up linearly over a real brake-buildup time instead of engaging instantly, so stopping distance always exceeds the naive v²/(2a) formula. Tune speed, system latency, buildup time and grip and watch the deceleration profile and stopping-distance penalty live.

This 2D bird's-eye companion to the 3D Autonomous Emergency Braking simulator asks the same question — will the car stop before the obstacle? — with a genuinely different braking model. Instead of jumping instantly from zero to peak deceleration once system latency ends, this model ramps braking force up linearly over a real brake force build-up time before it reaches full effect, exactly as hydraulic pressure and ABS engagement do in a real vehicle. The result is a stopping distance that always exceeds the naive v²/(2a) formula by a "build-up penalty" you can watch grow live on the deceleration-profile chart as you tune speed, latency, build-up time and grip.

⚙ Under the hood

A 2D bird's-eye companion to the 3D Autonomous Emergency Braking simulator, built on a genuinely distinct braking model: instead of jumping instantly to peak deceleration once system latency ends, braking force ramps up linearly over a real brake force build-up time, exactly as hydraulic pressure and ABS engagement do in a real vehicle. Watch the live deceleration-profile chart compare the ramped model against the naive instant-deceleration formula and see the resulting stopping-distance penalty grow as you tune speed, latency, build-up time and grip.
