The autonomous driving It is a reality that is advancing by leaps and bounds in the automotive industry. Currently, there is talk of level 3, in which the driver can remove his hands from the steering wheel and his feet from the pedals, allowing other tasks to be carried out while the car is moving. However, it is necessary to be alert to intervene in the event that the system requires the driver’s attention in a risky situation.
Until now, only four cars have this technology and have been approved by the competent authorities of some countries to circulate in “hands-free” mode in certain environments.
The first car to incorporate level 3 autonomous driving was the honda legendwhich was launched in March 2021. The technology called Traffic Jam Pilot Honda has been approved by the Japanese authorities for driving in certain environments and at speeds up to 50 km/h. This model became the first licensed car to allow the driver to perform secondary activities while the car is in motion.
The second manufacturer to gain approval for level 3 autonomous driving was Mercedes Benz. The models Classes and eqs they received the go-ahead from the German Federal Motor Transport Authority in December 2021 and subsequently, in January 2023, the approval of the US state of Nevada. In both cases, autonomous driving is allowed up to 60 km/h on certain types of roads. From May 2022, it is possible to equip the system Drive Pilot on these Mercedes-Benz models.
The third manufacturer to join this technology is Li Carwhose model Li L9 with autonomous driving technology AD Max has already been authorized in the Chinese city of Shenzhen to drive without driver intervention, allowing you to take your hands off the wheel without having to pay constant attention to the road.
There are two other cars that allow hands-free driving, but require the driver to remain attentive to the road environment. The new bmw 5 series has the system Driving Assistant Professionalwhich allows driving without hands on the wheel in Germany, the United States and Canada, reaching speeds of up to 130km/h on the same type of roads.
However, strictly speaking, this is not a level 3 autonomous driving, but rather a level 2.5. The main difference is that the driver cannot completely forget about driving or take their eyes off the road to perform other tasks, since an interior camera system monitors their behavior and issues an alert if they stray off the road. A similar case is that of Ford and its technology Ford Blue Cruiseapproved for use in the United States, Canada and the United Kingdom, which allows hands-free driving at speeds of up to 130 km/h, but also requires the driver to remain alert.
He windshield it plays a key role in all these technologies, since it houses the sensors and cameras necessary for the operation of driver assistance and autonomous driving systems. These cameras and sensors are the “eyes” of the ADAS and autonomous driving systems, as they capture information from the environment and allow the vehicle to process it accurately to make appropriate decisions.
Front cameras mounted on the windshield are especially importantas they enable the vehicle to reliably detect objects and people at all times using image processing combined with artificial intelligence methods.
The cameras work in conjunction with the radarin charge of determining the relative speed, distance and position of the objects that are around the vehicle, as well as with the leading sensor, which accurately measures the distance, position and height in three dimensions.
When the windshield is replaced, it is necessary to remove the cameras from the damaged glass and mount them on the new one. In addition, one must carry out a recalibration by qualified specialists to ensure that the systems work with the highest precision and provide the correct information. When this operation is not carried out or is carried out incorrectly, security systems do not adequately recognize the environment, which can cause accidents by not correctly calculating distances and time.
While only a few models currently have this approved technology, more brands are expected to achieve higher levels of autonomous driving in the future. It’s just a matter of time…
