A Forward Looking Radar Sensor for Adaptive Cruise Control with Stop & Go and Cut In Situations Capabilities implemented using MMIC technologies.


The project's goal is to develop a forward-looking radar sensor for an Adaptive Cruise Control system with stop&go and cut-in situation capabilities. A single sensor with a seven-beam antenna will provide improved angular coverage to overcome the limited angular coverage and close-range tracking capabilities of current radar sensors. This will enable the implementation of stop&go modes and the acquisition of new targets in cut-in situations. The sensor's improved range resolution will allow target tracking at close distances. These two features will allow the implementation of stop&go modes for highway driving, and they will be developed to allow the future incorporation of stereoscopic vision technology for improved urban driving. The sensor construction will be implemented using MMIC technology. Low-cost RF circuitry and metallised plastic antenna technologies will enable mass-market production. The FLRS hardware and software will be validated by road testing in demonstrator vehicles (trucks and cars).

The project's primary objective is to develop and demonstrate a Forward Looking Radar Sensor (FLRS) with improved capabilities that will allow operation in stop&go modes and early detection of cut-in situations. This will enhance the functionality of the sensor in an Autonomous Cruise Control system. Additionally, but no less important, is to demonstrate the feasibility of a low-cost, high-volume production design that will allow the product to be mass-produced. These objectives will be achieved with a multibeam antenna utilizing metallised molded plastic and a multichannel RF transceiver using MMIC technology. The FLRS will consist of a single, multibeam, integrated sensor and include unique built-in sensor self-test capability and algorithms for adaptive waveform generation and multiple target tracking. This advanced driver assistance system will improve safety in dense traffic and reaction to emergency situations by providing enhanced range resolution and angular coverage.

Work description:
The system components, including multibeam antenna, MMIC chipset, RF transceiver module, electronic hardware and FLRS algorithms will be developed based on prior specifications. Following FLRS integration and the development of embedded software for radar signal processing and control algorithms, systems will be set up for the collection and analysis of data in test vehicles. These vehicles will be used to evaluate and validate the system in high-speed, stop&go and cut-in situations, including short- and long-term validation and performance analyses. Examination of safety and legal (liability) issues, identification of risks in market introduction and identification of optimum channels for dissemination and sharing information will complete the project.
