Technical Deep Dive: How It Works in Active Suspension Systems

The NEWBASE Accelerometer Sensor measures linear acceleration along one axis—typically vertical (for pitch and bounce) or lateral (for roll). This data is sent in real time to the Electronic Control Unit (ECU), which uses it to:

• Detect road surface irregularities (bumps, potholes)
• Monitor body motion during cornering, braking, or acceleration
• Trigger immediate damping adjustments in e-dampers or active suspension systems

For example:

• When the sensor detects a sharp upward motion (e.g., hitting a curb), the ECU increases damping force to prevent excessive body movement.
• During smooth cruising, it reduces damping for enhanced comfort.

According to research published by SAE International, integrating high-resolution accelerometers into suspension systems can improve ride comfort by up to 35% and reduce body roll by 20%, significantly enhancing driver confidence and passenger experience.

Our use of PSI5 (Pressure Sensor Interface 5) ensures reliable signal transmission even in electrically noisy environments such as underbody installations.
