A Finnish Tech Company Is One Step Closer To Bringing Us Autonomous Cars

Sensible 4 Ltd, a Finnish tech company that specializes in software development for Autonomous Cars, will release Dawn in 2022, the first software in the field to withstand extreme weather, the company announced on Tuesday.

The problem is the reality of harsh weather conditions, as that is when people rely on their cars the most. “Why would we develop a system that only works in optimal conditions, in warm, clear, and sunny weather, as that’s not the reality for most of the people?” said Harri Santamala, Sensible 4’s CEO.

Dawn will be available for application on any four-wheel vehicle, but Sensible 4 is gearing towards shuttle buses, as it is “easily integrated” into the system.

“Our basic concept is that the vehicle must work in everyday conditions,” Santamala added. “We believe this is the way autonomous driving becomes mainstream.”How do self-driving cars work?Sensors. Usually, cameras. “Cameras are good in detecting and classifying objects in the vicinity of the vehicle, but they see poorly in the dark or through rain and fog, and they also have difficulty in accurately assessing distances to objects,” explained Santamala.

LiDAR (light detection and ranging) sensors, commonly used with self-driving prototypes, work by focusing on their object with a laser light, and then measuring the reflection to calculate distance and size.

Back in 2019, a Rehovot-based robotic vision start-up Lirhot systems developed a novel method of navigation: a camera-like sensor inspired by insect navigation. Most leaders in the industry rely on LiDAR sensors.

Others, namely Tesla CEO Elon Musk, uses navigation-based sensors.“In nature, you have bugs and insects that navigate in a specific way, and we’re copying that to enable autonomous vehicles to see,” Lirhot CEO Shlomi Voro, an applied physicist with dozens of patents in the field of quantum physics, told The Jerusalem Post at the time.

Santamala explained that their [LiDAR’s] “performance also suffers from rain and fog.” Small particles from the air get in the way of the laser beam. LiDAR is one type of sensor. There are countless others used in Autonomous Cars driving that make it safe.

The job of the software — like the one that will be offered by Sensible 4 — is to combine and analyze all the data coming in from the different sensors, and use it to secure the safety of the drivers.So, even though it relies heavily on LiDAR data, it was tested in harsh weather conditions, and worked 50% of the time.

How? “Advanced probabilistic model of positioning.” It “measures the shape of terrain and buildings surrounding the vehicle, and effectively filters out noise and outliers,” explained Santamala.
