New Concept of a Compact Lidar Scanner for ACC and Safety Applications

2009-04-20
2009-01-0639
This contribution deals with the development of a new scanning time-of-flight Lidar device for automotive use. Originally designed for safety applications, it provides a horizontal field of view of up to 170°. ...A detection range of up to 170 m enables tasks such as Full Speed Range ACC (FSRA), thanks to its technology based on a production proven IDIS® 1.0 circuit with Multibeam Lidar. A brushless DC Motor and a small momentum of inertia ensure the precision and sturdiness required for automotive applications.

Multiple object detection and tracking are central aspects of modeling the environment of autonomous vehicles. Lidar is a necessary component in the autonomous driving system. Without Lidar sensors, we will most probably not see fully self-driving cars become a reality. ...In advanced driver assistance systems or automated driving systems, 3-D point clouds from lidar scans are typically used to measure physical surfaces. Lidar is a powerful sensor that you can use in challenging environments where other sensors might prove inadequate. ...Lidar is a powerful sensor that you can use in challenging environments where other sensors might prove inadequate. Lidar can provide a complete 360-degree view of a scene. This paper designs Lidar based multi-target detection and tracking system based on the traditional point cloud processing method including down-sampling, denoising, segmentation, and clustering objects.

2020-01-0080
Advanced Driver Assistance Systems (ADAS) enable safer driving by relying on the inputs from various sensors including Radar, Camera, and LiDAR. One of the newly emerging ADAS features is Predictive Cruise Control (PCC). PCC aims to optimize the vehicle’s speed profile and fuel efficiency. ...This paper presents a novel approach of using the point cloud of a LiDAR sensor to develop a PCC feature. The raw point cloud is utilized to detect objects in the surrounding environment of the vehicle, estimate the grade of the road, and plan the route in drivable areas. ...This paper also discusses the developed algorithms of the LiDAR data processing and PCC controller. These algorithms were tested on FEV’s Smart Vehicle Demonstrator platform.

An ADAS Feature Rating System: Proposing a New Industry Standard

2019-10-07
2019-24-0251
More than 90% of new vehicles include Advanced Driving Assistance Systems that offer features such as Lane Keep Assist and Adaptive Cruise Control [1]. These ever-improving vehicle systems present a great opportunity to increase driving safety and reduce the number of roadway deaths and injuries. Indeed, they are already having a positive effect. However, the wide variety of features offered in the marketplace can be confusing to consumers, who may not clearly understand their vehicles’ true capabilities and limitations, or have an easy way of comparing system performance between vehicle models. This lack of information has the potential to reduce the safety gains of ADAS features by increasing the risk of improper use. To encourage transparency in the marketplace and thus engender the maximum positive effect of ADAS technologies, this paper proposes a five-level rating system, which utilizes diamonds to denote significant milestone achievements in vehicle system performance.

Comparison of Lidar-Based and Radar-Based Adaptive Cruise Control Systems

2000-03-06
2000-01-0345
Since the late 1980s, Delphi Automotive Systems has been very involved with the practical development of a variety of Collision Avoidance products for the near- and long-term automotive market. Many of these complex collision avoidance products will require the integration of various vehicular components/systems in order to provide a cohesive functioning product that is seamlessly integrated into the vehicle infrastructure. One such example of this system integration process was the development of an Adaptive Cruise Control system on an Opel Vectra. The design approach heavily incorporated system engineering processes/procedures. The critical issues and other technical challenges in developing these systems will be explored. Details on the hardware and algorithms developed for this vehicle, as well as the greater systems integration issues that arose during its development will also be presented.

2023-01-0827
The model vehicle is equipped with common ADAS sensors, such as optical cameras and LiDARs, which are known to be heavily affected by adverse weather. Quantification metrics are designed and applied to ADAS datasets to investigate sensor performance in conjunction with related phenomena, such as the perceived rain characteristics of a moving vehicle.

A Millimeter-Wave Forward Looking Radar Sensor for Automotive Applications

1998-10-19
98C040
The use of very short wavelength radar sensors for closed loop adaptive cruise control (ACC) and obstacle detection has been demonstrated as part of various international research and technology demonstration programs (e.g. PROMETHEUS in Europe). The first radar systems for distance measurement and target tracking are now under development, with vehicle trials already under way in several countries. This paper describes a 77 GHz radar sensor which will begin production next year (1999) as a headway sensor, initially for use in cruise control systems. The challenges facing the sensor manufacturer include the development of robust product designs and process technologies suited to the high volume and reliability demands of the automotive market, whilst achieving this at a sustainable production cost. The key design features of such a product are described, together with the major factors influencing cost and performance.
