Vehicles like Ford and others are equipped with a power lift gate. Ideal operation is Lift gate to open upon customer signal or approach.
Currently there are three methodologies to actuate rear lift or tail gate opening:
- Activate with button located in the lift / tail gate – requires you to manage packages in hand, if any.
- Through KEYFOB actuation – again requires you take KEYFOB out of pocket and manage packages in hand, if any.
- Through Foot Kick Movement like in Ford or other gesture recognition protocols. Quality concerns on correct recognition of gesture signal and single speed motor speeds.
Proposed Solutions
- Integrate gesture recognition with smart brushless motor where speed can be controlled.
- Project Welcome light to indicate correct gesture signal to remove customer confusion.
- Project high intensity (1000 nits) daytime / night time intensity control image to direct correct foot placement or hand gesture.
Optical Sensor from NEONODE to project Welcome Light Sequence and transmit gesture signal to integrate FZB Technologies brushless motor and electronics. Vehicle architecture of brushless motor electronics through LIN interface with vehicle security module.
- Electronics provides lift gate position sensing and automatic calibration
- Variable load management and anti-pinch features
- Variable lift gate speed operations
Advantages:
Integrated small package solution provides small package integrating the electronics and motor in the same envelope. Sensor and welcome light located under rear license plate or tail light.
FZB brushless motor electronics operate software that controls the feature and:
- Interpret signals from in vehicle lift gate controller to determine operations.
- NEONODE lift gate position sensing with automatic calibration.
- Variable load management and anti-pinch features.
- Variable lift gate speed operations.
- Cost efficient solution.
