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.
