This budget-friendly sensor device complements radar and camera systems

Thanks to AI, driverless cars have become a reality and are generating quite a buzz by hitting the road. With the help of improvements in driver assistance system, comprising of cameras, LiDAR and radar sensors, automated vehicle navigation has and is becoming capable of tackling real-life traffic situations.

Adding to the ongoing development for autonomous vehicles (AVs), Robert Bosch GmbH, a leading Germany-based IoT company that offers innovative connectivity technology and solutions, has devised a cutting-edge LiDAR sensor that is deemed suitable to cover both long and close ranges, be it open highways or busy city streets.

Although Bosch hasn’t released the technical details of the LiDAR sensor publicly, it is expected that the sensor will work very much on the principles of the company’s fourth-generation long-range radar sensor (LLR4) – except that the sensor will be transmitting laser pulses instead of radio waves.

The LLR4 is a monostatic multimodal radar with a frequency range of 76 to 77 GHz that creates a focussed beam at an angle of ± 6 degrees. It has a detection range of 0.36 to 250 metres for providing excellent long-range detection. In the near range, it can detect objects at a distance of up to five metres.

Benefits

In addition to being cost-effective, the LiDAR sensor complements the radar and the camera system. While an object’s narrow silhouette, such as that of a bike, can escape radar detection and harsh lighting can daze the camera system, a LiDAR sensor is unaffected by these events and can thus provide reliable measurement and detection. Together, these three create a highly effective driver assistance system.

With this advancement, Bosch has joined the likes of Valeo, Aptiv, Continental, Autoliv and Hella in developing LiDAR systems for autonomous vehicles.

“By filling the sensor gap, Bosch is making automated driving a viable possibility in the first place. We want to make automated driving safe, convenient, and fascinating. In this way, we will be making a decisive contribution to the mobility of the future,” says Bosch management board member Harald Kroeger.

He further adds that the goal behind this is to make automated driving a safe, convenient and fascinating experience for a decisive contribution to the mobility of future vehicles.

Bosch will be displaying its latest development at the Consumer Electronics Show 2020 in Las Vegas, the US, from 7 January 2020 to 10 January 2020.
