Occupancy grid filtering is important for navigation and localization in dynamic environments. The techniques that have been proposed in the past research, such as the Bayesian occupancy filter and the sequential Monte Carlo Bayesian occupancy filter, involve the independent consideration of all grid cells and, thus, are inaccurate and computationally expensive. To solve this problem, we propose a...
This paper presents a sensor fusion concept based on capacitive and ultrasonic techniques for distance measurement in automotive applications. Although ultrasonic sensors are a well accepted technology for distance sensing applications, they reveal drawbacks in the immediate vicinity of a vehicle. Capacitive sensors are suited for distance measurements of up to 0.3 m and may also provide information...
We describe a general architecture of vehicle perception system developed in the framework of the European project PReVENT-ProFusion. Our system consists of two main parts: the first part where the vehicle environment is mapped and moving objects are detected; and the second part where previously detected moving objects are verified and tracked. In this paper, we focus on the first part, using occupancy...
Car manufacturers, research institutions and governments are challenged by decreasing the number of road traffic fatalities in spite of rapidly increasing traffic volumes. One approach is to enhance the ldquointelligencerdquo of modern cars in anticipating dangerous driving situations. Besides wireless communications with the traffic environment, context perception enabled by well-known technologies...
The application of environment sensor systems in modern - often called ldquointelligentrdquo - cars is regarded as a promising instrument for increasing road traffic safety. Based on a context perception enabled by well-known technologies such as radar, laser or video, these cars are able to detect threats on the road, anticipate emerging dangerous driving situations and take proactive actions for...
Modern cars comprise various driver assistance applications which depend on reliable surveillance of the vehiclepsilas environment. Therefore, sensors known from aviation and military - like radar or laser - are combined to multi-sensor systems and employed to provide specific observation data. The actual choice of the single sensors depends on the scope of the application and in turn has a considerable...
24 GHz ultra-wide band short-range radar sensors are designed to improve safety and comfort functions in automotive applications. For cost-effective production these sensors can be manufactured as SiGe radar sensors. For an improved ACC functionality the 77 GHz long-range radar is combined with 24 GHz UWB short-range radar. This sensor fusion allows the detection of objects in the near surroundings...

This paper presents a configurable and generic platform architecture suitable to interface several kinds of sensors for automotive applications. A platform-based design approach is pursued to reduce time-to-market. The platform is essentially a library of hardware and software reconfigurable resources. It is based on a microprocessor core plus a set of analog and digital peripherals dedicated to signal...
