Continental has introduced the fifth generation of its short- and long-range radar sensors. These will enter series production in 2019 and will feature greater capacity. Continental says that these cater to vehicle manufacturers’ different requirements and electrical-electronic (E/E) architectures as they are based on a scalable modular principle. Using 77 GHz technology, the sensor resolution increases and can detect smaller objects, such as an exhaust pipe that has fallen off, more accurately. With long-range radar, a range of up to 900 feet and an opening angle of ±60° are possible in the highest expansion stage depending on the required performance. Continental suggests that with short-range radar, precise parking functions can be executed easily, in addition to functions such as blind spot detection, lane change assist or rear cross traffic alert.
Continental’s radar sensors are based on what the company describes as a highly sophisticated radar technology and the new generation claims advances in compactness and flexible usage.
The image of the surroundings produced by the radar is sent to a central control unit such as the Assisted & Automated Driving Control Unit. In this way, different E/E architectures of vehicles can be covered using a single sensor concept. In addition to today’s standards for bus systems, such as High-Speed CAN and CAN-FD, the fifth generation is already prepared for Automotive Ethernet, thanks to the hardware concept, which ensures that the necessary bandwidth for transmitting sensor raw data to the Assisted & Automated Driving Control Unit is available.
One of the features of the new generation is a higher resolution compared to previous radar generations, enabling a more exact snapshot of the current traffic situation. In addition, road boundaries like curbstones as well as the height of objects, such as the end of a traffic jam under a bridge are detected, says Continental, thanks to the sensors’ evaluation measurement accuracy. Even the entry-level variant of the long-range radar has a range of 600 feet and an opening angle of ±45°. The expansion stage currently in preparation will look 900 feet ahead, with an opening angle of ±60°.
