DENSETRAFFIC - A Forward Looking Radar Sensor for Adaptive Cruise Control with Stop & Go and Cut In Situations Capabilities implemented using MMIC technologies.
Overview
Background & policy context:
There was a need 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 shall provide improved angular coverage to overcome the limited angular coverage and close-range tracking capabilities of current radar sensors. This was supposed to enable the implementation of stop&go modes and the acquisition of new targets in cut-in situations.
The sensor's improved range resolution shall allow target tracking at close distances. These two features should allow the implementation of stop&go modes for highway driving, and they ought to be developed to allow the future incorporation of stereoscopic vision technology for improved urban driving. The sensor construction shall be implemented using MMIC technology. Low-cost RF circuitry and metallised plastic antenna technologies should enable mass-market production. The FLRS hardware and software have been validated by road testing in demonstrator vehicles (trucks and cars).
Objectives:
The project's primary objective was to develop and demonstrate a Forward Looking Radar Sensor (FLRS) with improved capabilities that allows 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, this is to demonstrate the feasibility of a low-cost, high-volume production design that might allow the product to be mass-produced. These objectives should be achieved with a multibeam antenna utilising metallised moulded plastic and a multichannel RF transceiver using MMIC technology. The FLRS consisted 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 was supposed to improve safety in dense traffic and reaction to emergency situations by providing enhanced range resolution and angular coverage.
Methodology:
There were test vehicles 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. These test vehicles were equipped with systems for the collection and analysis of data utilizing system components such as multibeam antenna, MMIC chipset, RF transceiver module, electronic hardware and FLRS, developed based on prior specifications. Examination of safety and legal (liability) issues, identification of risks in market introduction and identification of optimum channels for dissemination and sharing information completed the project.
