Automotive Electric Tailgate

AR Light and Shadow Sensing Tailgate - Light Sensing (Laser) Kick

A single-point LiDAR is equipped with an AR projection/visible light indicator module and integrated smart sensing devices, which can be installed in the trunk. The LiDAR spot overlaps with the AR projection cursor/visible indicator light cursor. The LiDAR determines whether the user is stepping on the cursor by detecting changes in distance and other characteristic values. This works in conjunction with the vehicle's overall system to achieve AR projection, step detection, and tailgate opening and closing functions. It allows for the automatic opening and closing of the car's tailgate without any physical contact with the vehicle.

Key Highlights

1. Easier to trigger than capacitive type

The AR light and shadow sensing tailgate equipped with single-point LiDAR has a detection response sensitivity, with a success rate of over 99% for opening. When a user triggers the AR projection at the rear of the vehicle and steps on the cursor, the system can automatically and quickly sense this action and respond promptly. Compared to traditional "kick-to-open" sensing tailgate technology, it significantly reduces the likelihood of sensing failures, thereby avoiding the embarrassment of repeated attempts to open the tailgate without success.

2. Low false trigger rate

With precise sensing technology (high-sensitivity sensors and intelligent recognition algorithms), specific trigger condition settings (designated operational area), strong environmental adaptability (unaffected by weather and objects such as plants or metals under the vehicle chassis), and comprehensive user operation feedback (visual and step detection), the system effectively reduces the probability of false triggers.

3. Visible trigger projection pattern

Using optical projection technology, a corresponding pattern or marker is projected onto the ground at a certain distance from the tailgate. Thanks to the high directivity of the single-point LiDAR, the radar spot perfectly aligns with the projection. Users only need to lightly step on the projected pattern for the tailgate to automatically open or close. This visual operation method allows users to clearly see the opening area and operation instructions for the tailgate, making the operation more convenient and intuitive, without the need to search or guess the sensing area as in traditional methods.

4. Flexible installation arrangement

The installation position is adaptable, accommodating various vehicle designs and meeting personalized user needs. This flexibility optimizes space utilization while enhancing installation efficiency and compatibility.

User Value

1. Convenience

When users have their hands full and find it inconvenient to open the tailgate, they can easily use the AR projection on the ground. By simply stepping on the projected icon, they can open or close the tailgate without searching for physical buttons, greatly enhancing the ease of accessing the tailgate.

2. Technological Experience

The AR projection electric tailgate serves as an advanced automotive technology feature, adding a strong sense of innovation and style to the vehicle. It provides users who pursue technological trends with more enjoyment and satisfaction.

3. Nighttime Usage Advantage

In low-light environments, traditional methods of opening the tailgate can be quite inconvenient. However, the AR projection electric tailgate can project clear operational guides, allowing for accurate functioning even at night. Additionally, the projection itself can provide some illumination, lighting up the area around the tailgate.

Technical Advantages

The entire system consists of three main modules: single-point LiDAR, AR projection, and main control board.

Single-Point LiDAR: The system uses single-point LiDAR to detect the user's actions for opening or closing the tailgate. The LiDAR performs distance detection based on the user's movements and sends the distance data of the entire process to the main control board.
AR Projection: The system utilizes AR projection to map indicative patterns that guide customers in performing accurate and effective operations.
Main Control Board: The main control board manages the AR projection and guides the user in opening or closing the tailgate. During the user's operation, the main control board collects distance data of the entire process through the single-point LiDAR and uses algorithms to process and determine the actions, ensuring stable and correct opening and closing of the tailgate.
