– Long-range handling complements radar and camera. Bosch’s long range handle sensor will be the first solution suitable for automotive use, allowing cars to “see” a three-dimensional view of the road.
Minapim by Hernan Valenzuela: The in-house developed Lidar sensor will be displayed at the Consumer Electronics Show in Las Vegas starting January 7 (next week), will cover long and short-distance lanes on highways and in the city and will work in conjunction with the company’s camera and video technologies. radar.
For safe automated steering to come true, a third sensor principle, besides the camera and radar, is required. Bosch is preparing the long range handle sensors for production – the first LIDAR system (detection and light range) suitable for automotive use. This laser-based distance measurement technology is indispensable for SAE level 3 to 5 driving functions.
Bosch’s new Lidar sensor covers long and short ranges – on highways and in the city. By exploiting economies of scale, Bosch wants to lower the price of sophisticated technology and make it suitable for the mass market. “By filling the sensor gap, Bosch is making automated steering a viable possibility,” says Harald Kroeger, a member of the Bosch board of directors.
Lidar technology, which uses light-based sensors to generate a three-dimensional view of the road, remains a relatively young technology that is still in flux. In its current form, it is too expensive for mass-market use, but if a cheaper coping sensor were widely adopted, it could provide deeper data that would allow autonomous cars to detect the distance of other road users, such as pedestrians.
Tesla’s Elon Musk said earlier that coping is a “very foolish task” and said the technology was “doomed.” Tesla vehicles use cameras and radars as their vision system for driving.
Hundreds of millions of dollars have been invested in deal start-ups. Major suppliers are in the running and are developing the technology: Valeo (VLOF.PA), Aptiv (APTV.N) and Continental (CONG.DE).
Bosch technology for all automated driving situations
Only the parallel deployment of three sensor principles ensures that automated steering offers maximum safety when launched. This was confirmed by Bosch analysis, where developers investigated all use cases of automated steering functions – from highway assistance to fully automated steering in cities.
For example, if a motorcycle approaches an automated vehicle at high speed at an intersection, handling is required, in addition to the camera and radar, to ensure reliable detection of the two-wheeled vehicle. In this case, the radar may strive to detect the narrow silhouette of the bicycle and the plastic fairings. Also, a camera can always be overshadowed by the bright light falling on it. As such, radar, camera and handling are required, with all three technologies complementing each other perfectly and providing reliable information in all driving situations.
Lidar sensor is an essential element in automated driving
We can think of the laser as a third eye: in Lidar systems, the lidar sensor emits laser pulses and captures the laser light that is scattered back. The system calculates distances based on the measured time required for light to recover. Lidar offers very high resolution with a long range and wide field of view.
As a result, the laser-based distance measuring tool can safely detect even non-metallic objects over a long distance, such as roadside stones. This means there is plenty of time to initiate steering maneuvers such as braking or deflecting.
At the same time, the use of vehicle handling exposes system components such as the detector and the laser to many voltages – above all, with regard to temperature resistance and reliability over the life of the vehicle.
Because Bosch can leverage its sensor expertise and system know-how in the areas of radar and camera technology when developing the handle, the company can ensure that all three sensor technologies fit together. “We want to make automated driving safe, convenient and fascinating. This will make a decisive contribution to the mobility of the future, ”says Kroeger.
Bosch’s long-range handling will not only meet all safety requirements for automated steering, but will also allow automakers to efficiently integrate technology into a wide range of vehicle types in the future.
AI artificial intelligence is making care systems even safer
Bosch is a leader in sensor technology innovation for driver assistance and automated steering systems.
The company has been developing and manufacturing millions of ultrasound, radar and camera sensors internally for many years. In 2019, sales of Bosch driver assistance systems increased by 12% to around 2 billion euros. These assistance systems are paving the way for automated steering.
Bosch engineers have recently been able to take car camera technology to a new level by enhancing it with artificial intelligence. Camera technology detects objects, categorizes them into classes such as vehicles, pedestrians or bicycles and measures their movement. In congested urban traffic, the camera can also recognize and classify vehicles, pedestrians and cyclists that are partially obscured or quickly and reliably. This allows the vehicle to trigger a warning or emergency braking maneuver as needed.
Bosch engineers are also continually refining radar technology. Bosch’s latest generation of radar sensors are even better at capturing the vehicle’s surroundings – even in bad weather or low light conditions. Its longer detection range, wide aperture and high angular separability are the basis for this enhanced performance.
