According to statistics, more than 80% of traffic accidents involving vehicles are caused by human factors. Drivers have visual limitations, and it is easy to get fatigued when concentrating on driving for a long time. These uncertain factors pose certain threats to traffic safety.
The author believes that vehicles equipped with autonomous driving capabilities will react faster than humans, avoiding traffic safety accidents caused by human factors. Of course, autonomous driving also needs to have higher safety. How to achieve this? This starts with high-precision positioning.
High-precision positioning ensures the driving safety of intelligent vehicles
To achieve safe autonomous driving, in addition to equipping autonomous vehicles with cameras as "eyes" to let them see the road conditions clearly, and radars as "ears" to help them identify surrounding obstacles, they also need to be given the unique human "sense of direction".
High-precision positioning accurately judges the vehicle's own absolute position through a high-precision absolute reference system. Combined with high-precision maps, it can provide the vehicle with accurate absolute position information, enabling it to obtain a "sense of direction". It complements the relative position of sensors, and ultimately jointly improves the safety of intelligent driving.
SpatiX has the world's largest high-precision spatiotemporal service network. Intelligent vehicles equipped with SpatiX Cors Center can achieve centimeter-level positioning accuracy. On expressways covered by high-precision maps, they support the activation of autonomous driving assistance functions, bringing users an intelligent travel experience.
When encountering extreme rain and snow weather, the interference to cameras and radars will increase. At this time, autonomous vehicles are like losing their "eyes" and "ears" and have no sense of direction. SpatiX can still stably provide centimeter-level high-precision positioning services in extreme environments such as ice and snow coverage, allowing smart cars to "see" more clearly.
So, during the vehicle's driving process, how can intelligent vehicles independently judge whether the received navigation information is credible, usable, and safe? This requires the help of integrity. SpatiX has groundbreakingly introduced integrity indicators from the aviation field into the spatiotemporal intelligence domain. Currently, SpatiX's integrity risk for reliable positioning results is as low as 10⁻⁷ per hour, which is equivalent to a risk that may occur only once in 1000 years.
At the same time, SpatiX is also conducting the world's largest-scale high-precision positioning road tests, covering major urban expressways and highways across the country. These tests verify the stability of high-precision positioning services in multiple scenarios such as different latitudes, different altitudes, different road conditions, and different weather conditions, continuously improving product quality.
