Product Introduction

As a new type of intelligent park micro-transportation vehicle that integrates travel, technology, information, entertainment and other functions, the main goal of the intelligent driving sightseeing car is to provide customers with safe, intelligent and convenient travel services and enhance the added value of surrounding businesses. This product satisfying the  needs of low-speed micro-vehicles in general closed scenic spots, has L3+ intelligent driving functions, and provides tourists with entertainment value-added services based on high-precision positioning.

Description of typical application scenarios

Automated connection services

Smart-driving sightseeing vehicles can conduct autonomous operations within the closed scenic spots, and independently complete commuter tasks through preset routes and instructions. They can realize automatic driving docking on several fixed routes, and can customize the station settings on the operating route. They can make comprehensive judgments based on the vehicle's current task, traffic conditions ahead of the vehicle's driving route, and the overall road conditions, and conduct normal drive, following, deceleration, parking, emergency parking, or detours.

Active safety system（optinal）

The low-speed active safety system includes two major features: high-precision geo-fencing and active driving safety, which will maximize the safety of users. High-precision geo-fencing technology monitors the area where the vehicle is located in real time, and based on the preset conditions of the area that are dynamically updated in real time based on the current position of the vehicle, it dynamically calculates the safety threshold of the current vehicle's safety posture and linear angular velocity, and ultimately controls the vehicle's driving direction and speed to ensure the safety of surrounding pedestrians, passengers and vehicles. The main goal of the active driving safety function is to ensure that the vehicle can perceive the operating environment around the vehicle, identify obstacles, limit the vehicle's operating speed and direction, and ensure the safety of surrounding pedestrians, passengers and vehicles during intelligent driving and manual driving. Comply with the responsibility-sensitive safety model.

Self-warning

The smart driving sightseeing car is equipped with a full-vehicle system self-inspection function. When the vehicle fails or does not meet the conditions for automated operation, the vehicle can automatically downgrade its operation and notify the management personnel through the networked system.

Human-computer interaction function（Optional/

customized）

The human-computer interaction function provides the most basic information interaction function for vehicle driving and intelligent driving. The human-computer interaction system is mainly reflected in the form of touch screen + voice (inside and outside the car) interaction. The vehicle has a complete vehicle-side digital experience, including LBS intelligent scenic spot guide, intelligent voice interaction and other functions

Data statistics and analysis（Optional/

customized）

The high-definition cameras and high-precision sensors equipped in the vehicles can conduct all-round monitoring and data collection of the environment in the area. When abnormal conditions are found, they can be warned in time and notify the management personnel to deal with them. Through statistics and analysis of data, it can help the management personnel better understand the park conditions and grasp the park safety, so as to make more scientific and reasonable decisions and management plans.

 Remote parallel driving（Optional）

The smart-driving sightseeing car has complete perception, decision-making and control capabilities, and also has 5G remote parallel driving function. The vehicle can be remotely taken over through the management backend parallel driving cockpit to realize intelligent scheduling and other functions.

Technical solutions

Automatic drive

The smart-driving sightseeing car uses sensors such as lidar, high-definition cameras, millimeter-wave radar, ultrasonic radar, etc., which can achieve 360-degree all-round environmental perception, have high-precision map positioning and path planning capabilities, and can autonomously control vehicle speed, direction, parking and other operations.

High-precision positioning technology

High-precision integrated navigation and positioning based on differential satellite signal-sensor fusion. When the satellite signal does not meet the conditions, the high-precision positioning solution based on sensor fusion can be switched;

Image recognition technology

The smart-driving sightseeing car uses deep learning algorithms and computer vision technology, which can quickly identify and track targets such as roads, vehicles, and pedestrians, providing more accurate and reliable data support for autonomous driving.

Cloud computing technology

Cloud computing technology: The smart-driving sightseeing car uses cloud computing technology, which can efficiently process and analyze massive amounts of data and provide more intelligent application services. At the same time, the cloud platform also supports remote monitoring and management, making it convenient for users to monitor and dispatch vehicles in real time.
