I have deep concerns and keen interests in autonomous vehicles. This article is based on recent news published by Daimler AG on Level 3 automated driving’s technical requirements.
The above news caught my eyes, and because they did not explain enough, I thought to write a detailed article on the subject.
The time you will spend in your private vehicle will transform in the future. The private life in cars gonna be change hell a-lot because Autonomous driving is happening more and more. Some fully automated cars are already in prototype mode, and soon we see them running on the roads.
There are 5 Levels of automation, and I briefly visualized these levels in my last article. You can read the article Data annotation and five levels of automation
Steering and braking – Drive Pilot?
The first query that comes to everyone’s mind when talking about self-driving cars, how driver pilot steering and braking works?
With the LiDAR sensor and redundant systems… DRIVE PILOT also has redundant steering and braking systems and an inessential onboard electrical system. It remains maneuverable even if one of these systems fails, and a safe handover to the driver can be confirmed. A powerful central control unit comes up with the necessary sophisticated software functions for depending on automated driving. Artificial intelligence is used for image development, for an instant. As a portion of the state-of-the-art safety architecture, all algorithms are deliberated twice.
Next-Generation Car Design Will Require Miniaturized Solutions
Who will dominate the race? Furthermore, how might driverless vehicles change society? While the car business’s eventual fate is as yet unwritten, here is the thing that we know: Industry pioneers should dominate network to convey the V2X (vehicle-to-everything) abilities completely self-ruling driving guarantees. Here’s an outline of key availability prerequisites to get that going.
To fit V2X frameworks in a car engine, manufacturers should create car grade scaled-down and profoundly integrated availability arrangements. Sensors and actuators are getting more modest as connections increment.
The Automotive Ethernet enables manufacturers to convey both force and information over a solitary pair of wires, either protected or unshielded. TE Connectivity has critical involvement with affirming the freedom and creepage edges important to achieve this target.
Simultaneously, manufacturers should decide and meet pollution and moisture resistances for frameworks. In-vehicle organizations will require the lightest and least fatty link congregations and connectors made at this point – which will be put in ever denser designs. TE helps the car business make these compromises and optimize their answers, to make information navigate frameworks quicker and in the most forcibly effective way, yet with less absolute material connector and cabling material.
Huge use of sensors in Driver-less cars, which sensors gonna be must use?
This is the fact that without using automotive sensors, the Level-3 of automated cars could not be possible, but the question is which type of sensors are being used and could be used?
There are mainly three types of sensors 1. Radar 2. Lidar and 3. Ultrasound sensors are used in combination with several other sensors and cameras to make Level-3 possible.
Most of the companies use LiDar sensors as their Go-to sensor, and even Daimler AG shared they are using LiDar sensors in their linked-video (the link is given above). They use Lidar for the optimal measurement of distance and speed; however, Lidar is also heavily used for object detection. This sensor is a multi-purpose sensor.
Positioning of semi driver-less cars
Positioning is a big question when cars are on the road with minimum attention from the driver. Mostly Automotive companies are using differential GPS systems to keep track of their level-3 automation.
How to teach car traffic signs and road geometry
While Daimler AG is using its own digital HD map for traffic signs detection, road geometry, and other related information, here most of the Automotive Companies are relying on getting a lot of traffic signs detection and road data from companies who own a large amount of roads data, and then they convert this data to their own systems as Daimler AG does.
A common question is what about using Google maps?
Well, Since the sky is always blue in the land of Google Maps, there may not be enough weather/light variation to make the images useful as training tools. Most of the training data, he said, would be collected by the cars themselves, in the real-world environments they’re tested in.- says Raj Rajkumar, a roboticist and autonomous vehicle authority at Carnegie Mellon University
How a partially driver-less car sees its surroundings?
Cameras come in the place when a car needs to see its surroundings. For example, Daimler AG uses the read-HD camera to enable their cars to see the emergency vehicles approaching from behind.
Bosch has recently launched one of the best cameras named MPC3 multi-purpose camera for autonomous driving, and they claim it is — better than the human eye. This camera is AI-enabled technology and could be replaced by any other low-quality camera for German auto-makers.
Increasingly Electrified Cars will require a new approach to safety:
Guaranteeing information trustworthiness inside useful safety applications is obligatory for independent driving since living souls will rely upon it. As information prerequisites develop, cars will increasingly energize. It is fundamental to guarantee safe information transport on the actual layer level along these lines and give the most noteworthy conceivable physical and information security assurances. Car organizations are examining where and when they can utilize optical-fiber-based availability to stay away from the electromagnetic obstruction. Fiber optic correspondences don’t encounter electromagnetic discharges, crosstalk, or sign mutilation. This implies optical correspondence network stations can be put close to high-control electric links and gadgets and give reliable working without safety concerns or impedance stresses.
Designs Must Be Redundant and Real-time
Self-governing driving will increasingly request increasingly more reliable organization-based constructions, requiring repetitive, continuous designs. These designs will arrange superior bunches in utilitarian areas and be associated with utilizing a focal passage in a fast information spine structure. Gathering sensors and actuators will be coordinated progressively.
To summarize, where almost all technical solutions are ongoing, and some are working fine for level-3 automated cars, some grey areas must not forget. We still don’t exactly know. What about car interconnectivity to other driver-less cars? And legal frameworks to meet the final approval criteria of level-3 automated vehicles. Almost every second Automotive Company has challenges and massively works on these hidden factors.
