Dual-axis velocity
Independent longitudinal and lateral velocity in a single sensor housing.
True speed over ground.
Dual-axis mmWave radar speed measurement for motorsport and high-performance vehicles. Slip-free, contactless and robust in rain, dust and darkness.
±300 km/h
IP68
90 g
<2 ms
100 Hz
<3 W
Features
Engineered for motorsport.
Previous optical industrial sensors were designed for stationary or industrial environments - not for the demands of the racetrack. Doppla is built from the ground up for motorsport: easy to integrate, reliable in rain, vibration and harsh conditions, and with latency below 2 ms for control loops that depend on true speed.
True speed over ground
Speed relative to the road surface - fully decoupled from wheel mechanics.
All-weather radar
Insensitive to spray, dust, dirt, ambient light and changing ground surfaces.
Ultra-low latency
<2 ms response time. Compatible with closed-loop traction and torque control.
Simple integration
CAN output, 9-32 V supply, no separate ECU.
Motorsport-ready
IP68, -40 to +65 °C, 90 g - designed for vibration and thermal extremes in racing.
Applications
From traction control to lap-time telemetry.
Wherever wheel speed is used as a substitute speed signal today, Doppla replaces it with a true measurement.
//
Traction control
Slip-free reference for closed-loop wheel-slip control.
//
ABS reference
True vehicle speed - independent of locked or spinning wheels.
//
Torque vectoring
Dual-axis input for yaw-rate and slip-angle control.
//
Yaw control
Lateral velocity as a direct measurement - not an estimate.
//
Vehicle dynamics
High-frequency telemetry with low latency for development and setup work.
//
Lap-time data
Reference speed for performance analysis and simulation correlation.
