Quick Answer

Why is my door opening randomly?

This is often 'ghosting' caused by radar interference or sensor drift. In Caterham, we see this frequently with older analog sensors. We upgrade these to digital units that filter out environmental noise.

Component Analysis

Operator Mechanics: We inspect the DC motor for overheating and replace worn brushes or the entire brushless unit if efficiency drops.

Sensor Fusion: In Caterham, we recalibrate Microwave Radar for motion and Active Infrared for presence to prevent ghosting.
