Sensor Box for Air Taxis Control Flying Taxis with Precision

Mit Bosch-Technik lernt das Auto fliegen: Der Zulieferer stellt eine Sensorbox für Lufttaxis zur Verfügung, mit der sich diese präzise steuern lassen.
With Bosch technology, the car learns to fly: The supplier provides a sensor box for air taxis with which they can be precisely controlled.

The Boston Consulting Group predicts that people around the world will take 1 billion flights in air taxis in 2030, once sharing services have also established a presence on fixed routes above the ground. Bosch is working on state-of-the-art sensor technology to make these flights safe.

With traffic jams a common occurrence in the world’s cities, frustrated drivers sometimes find themselves looking to the heavens for a little help from above. A few years from now, the skies could in fact offer a tangible solution. The Boston Consulting Group predicts that people around the world will take 1 billion flights in air taxis in 2030, once sharing services have also established a presence on fixed routes above the ground. What is more, most of those air taxis will be capable of operating without a pilot. Bosch is working on state-of-the-art sensor technology to make these flights especially safe, comfortable, and convenient. »The first flying taxis are set to take off in major cities starting in 2023, at the latest. Bosch plans to play a leading role in shaping this future market« says Harald Kröger, president of the Bosch Automotive Electronics division. To help it achieve this goal, the supplier has discovered a gap in the market. Conventional aerospace technology is too expensive, bulky, and heavy to be used in autonomous flying taxis. However, modern sensors that are also used for automated driving or in the ESP anti-skid system could have the potential to bridge this gap. That is why a team of engineers has combined dozens of sensors to create a universal control unit for flying taxis.

Featuring Bosch sensors already in use in production vehicles, the universal control unit is designed to ensure the ability to determine the position of the flying taxis at all times, allowing them to be controlled with precision and safety. Acceleration and yaw-rate sensors that accurately measure the flying vehicles’ movements and angle of attack, for example, provide the necessary data. Unlike current sensor systems in the aerospace sector, some of which cost tens of thousands or even several hundred thousand euros, Bosch can make use of its solution for a fraction of the cost. That is because the company uses production-tested sensors that Bosch has already been developing and manufacturing for the automotive industry for many years. 

The market for flights using electric air taxis in cities is set to see substantial growth in the years ahead. Test flights are scheduled to begin in cities such as Dubai, Los Angeles, Dallas, and Singapore in 2020. Experts expect commercial operations to begin in 2023. Although pilots will probably be on board at first, the light aircraft could start flying autonomously over the roofs of major cities as early as 2025, controlled by staff on the ground. By that time, roughly 3,000 flying taxis will be in operation worldwide, according to Roland Berger. That number will increase to 12,000 by 2030, with just under 100,000 flying taxis taking to the skies by 2050. Consultants from Morgan Stanley estimate that the market for flying taxis could even reach 1.35 trillion euros (1.5 trillion USD) by 2040, extending beyond the United States and southeast Asia to include large and medium-sized cities in Germany as well. In regions such as the Ruhr valley, the Frankfurt Rhine-Main metropolitan region, and the Munich/Augsburg/Ingolstadt metroplex, they have the potential to significantly speed up travel over short and medium distances.

The sensor box is equipped with MEMs as well as acceleration sensors that measure the movements of the aircraft. Built-in yaw-rate sensors measure the flying vehicle’s angle of attack, while magnetic field sensors gauge its compass heading. The package also includes pressure sensors, which use barometric pressure to measure altitude and dynamic pressure readings to determine the vehicle’s current speed.
