Since its quantity production in 2022, Golden Dragon third-generation 6-meter intelligent driving minibus,"Insight" has been widely used in various scenarios such as microcirculation buses, park commuting and shuttling, and scenic spot sightseeing.

From the perspective of vehicle market positioning, "Insight" is an upgraded product built on the basis of market demands and existing autonomous driving models "ASTAR" and "POLESTAR". Through the same platform, two products, No. 1 and No. 2, are created to meet the needs of two different fields: autonomous driving and microcirculation buses. From technical standards to application scenarios, "Insight" demonstratesg Golden Dragon first-mover advantage in the field of intelligent driving.

Let's start by introducing the upgrades"Insight"has made in vehicle basic performance as a pure electric low-entry bus model. First, "Insight"has been comprehensively optimized in body styling, dimensions, and overall layout. The front and rear body styling are basically consistent, and the side walls are symmetrically designed, which not only gives a more technological and futuristic look but also enhances the vehicle's modularity. To obtain more internal space, "Insight" length, width, and height dimensions have reached 599520952830mm, longer and wider than similar models; while achieving an internal height of 2121mm, the overall height has been reduced by 55mm, which is more conducive to passing through height-restricted sections within parks; the wheelbase is shorter, only 3790mm; while ensuring internal space, the vehicle has better passability, and the smaller turning radius brings flexibility and mobility, making it more suitable for microcirculation and other scenarios.

In addition, after the enhancement of interior space, "Insight" has achieved a standard 9+1 seating layout, with the last row of seats increased from 3 to 4 compared to similar models. The glazed area of the vehicle reaches 16.6 square meters, enhancing the transparency inside the vehicle and providing a good view for the driver and passengers. The net width of the electric sliding door reaches 1200mm, effectively improving the efficiency of boarding and disembarking during peak operation hours.

Why does "Insight" achieve better space and passability under the same conditions? Behind the seemingly simple data changes lie technological upgrades in vehicle layout and architecture. For models with the same 100kWh battery capacity, "Insight" battery box arrangement features one at the top and one at the front and rear, respectively. Compared to the top-two-rear-one arrangement, its axle load distribution is more uniform, enhancing handling stability. In terms of motors, "Insight" adopts a permanent magnet synchronous motor equipped with a two-stage reduction gearbox with a differential, which can provide stronger torque output during climbing and full load and protect the motor. Moreover, "Insight" uses an upper-spring motor solution, which, compared to the lower-spring arrangement, can effectively reduce impact and vibration on the motor, prolong its service life, and provide a smoother chassis, directly enhancing the comfort of driving and riding.

After introducing the technical upgrades of the base model, let's focus on the upgrades "Insight" has made in intelligent driving. It is understood that the "Insight" L4 autonomous driving model completely eliminates the driving area inside the vehicle. It uses automotive-grade solid-state LiDAR as the main sensor and is equipped with an all-around intelligent fusion perception system featuring 8+ solid-state LiDARs, front and rear millimeter-wave radars, 360-degree surround-view cameras, and short-range ultrasonic radars. By integrating the global navigation satellite system, sensor technology, and feature positioning technology, it can achieve centimeter-level high-precision positioning. The wire-controlled chassis adopts multiple redundancy design, with control reaching the millisecond level, and the lateral control accuracy can reach 0.1 degrees.

From its current overall performance, "Insight" has gained recognition from all parties in the market, indicating that Golden Dragon has explored a suitable technical route in the field of intelligent driving for buses: that is, based on the demands of real-world scenarios, to develop its own core technical capabilities and promote the transition of autonomous buses from demonstration operations to true commercial applications.
