Solution

LiDAR application solution for contactless powered-tailgate triggers

Use distance or distance change to detect a contactless gesture below the tailgate and pass the event to the body controller.

LiDAR detecting a contactless opening gesture below a vehicle tailgate

Scenario

Application scenario

Powered-tailgate triggers need to detect a foot or defined zone within limited body space. LiDAR supplies distance or trigger input; actuation, authorization, anti-pinch logic, and vehicle safety remain body-system responsibilities.

Engineering problem

Body geometry, ground clearance, and mounting angle constrain the trigger zone.
Shoes, pavement, water, contamination, and light affect measurements.
The gesture must be separated from passers-by, static objects, and invalid data.

Why LiDAR

A compact LiDAR provides continuous distance change so the controller can define zones, duration, and debounce rules.

Workflow

Define the trigger zone, gesture, response time, and fault handling.
Mount with clear line of sight and calibrate the body reference.
Implement thresholds, duration, debounce, and authorization in the body controller.
Validate shoes, pavement, weather, contamination, and false-trigger cases.

Technology comparison and selection

Dimension	Condition	LiDAR	Alternative	Alternative performance	Conclusion
Contactless gesture trigger	A controller must interpret distance change inside a defined zone.	Provides continuous distance for zones, duration, and debounce.	Capacitive or proximity switch	Supports fixed-point triggering with different sensing and mounting constraints.	Select and validate by body space, gesture, environment, and vehicle qualification requirements.

Selection

Product selection guide

Current material supports one explicit candidate. Its fit and boundary are shown directly without inventing an alternative.

Model	Key product facts	Best fit and rationale	Operating boundary	Product details
TF-Luna	Output data Single-point Distance Value Measuring range 0.2 ~ 8 m Interface UART, I/O, I²C Protection Without enclosure	TF-Luna is compact and low power and can provide single-point range input for approach, position change or trigger logic at a controlled tailgate mounting point.	Validate the full motion path, target surface, rain and dirt, occlusion and abnormal states; one range point is not anti-pinch or functional-safety certification.	View product

Installation and integration

Mount for the body space and target foot zone, avoid bumper occlusion and water paths, and integrate distance and data status into the body controller.

FAQ

Frequently asked questions

Can the LiDAR directly control a powered tailgate?

No. It provides distance or trigger input. Authorization, anti-pinch, fault handling, and actuation belong to the vehicle body system.
