TL;DR: In this article, a collision avoidance system for use with an unmanned vehicle is described, which includes a plurality of radar elements arranged parallel to the longitudinal axis of the unmanned vehicle, where the radar elements transmit a number of pulses about the vehicle and receive return signals from one or more objects within range of the vehicle.
Abstract: A collision avoidance system for use with an unmanned vehicle, the system includes a plurality of radar elements arranged parallel to the longitudinal axis of the unmanned vehicle wherein said radar elements transmit a plurality of pulses about said vehicle and receive a plurality of return signals from one or more objects within range of said vehicle. Upon detecting that one or more objects within range of said vehicle the system determines if the object is on a course with requires evasive action and suitably alters the vehicle's course in order to avoid a collision.

19 Mar 1999TL;DR: In this paper, a vehicle wireless transmitter system includes a collision avoidance sensor in a wireless transmitter, which generates a wireless signal such as a garage door opener signal, based upon information from the collision avoidance sensors.
Abstract: A vehicle wireless transmitter system includes a collision avoidance sensor in a wireless transmitter. The wireless transmitter generates a wireless signal, such as a garage door opener signal, based upon information from the collision avoidance sensor. The wireless transmitter generates a garage door opener signal when the collision avoidance sensor determines that the vehicle is within a predetermined distance of the garage. The wireless transmitter generates a garage door opener signal when the collision avoidance sensor determines that the vehicle is in the garage, the engine is no longer running and no motion is detected around the vehicle for a predetermined period of time.

TL;DR: A refined method for estimating the potential effectiveness of a technology designed to support the car driver in mitigating or avoiding pedestrian accidents is presented and indicates a reduction of 24 percent in pedestrian fatalities for crashes where the pedestrians were struck by the front of a passenger car.
Abstract: Accident data show that the vast majority of pedestrian accidents involve a passenger car. A refined method for estimating the potential effectiveness of a technology designed to support the car driver in mitigating or avoiding pedestrian accidents is presented. The basis of the benefit prediction method consists of accident scenario information for pedestrian-passenger car accidents from GIDAS, including vehicle and pedestrian velocities. These real world pedestrian accidents were first reconstructed and the system effectiveness was determined by comparing injury outcome with and without the functionality enabled for each accident. The predictions from Volvo Cars' general benefit estimation model are refined by including the actual system algorithm and sensing models for a relevant car in the simulation environment. The feasibility of the method is proven by a case study on an authentic technology; the auto brake functionality in collision warning with full auto brake and pedestrian detection (CWAB-PD). Assuming the system is adopted by all vehicles, the case study indicates a reduction of 24 percent in pedestrian fatalities for crashes where the pedestrians were struck by the front of a passenger car.

01 Jun 2015TL;DR: In this paper, various examples relate to systems, methods, and equipment that provide location and velocity monitoring of both a user's vehicle and another vehicle to avoid collision and provide additional information based thereon such as the probability of collision.
Abstract: The various examples disclosed herein relate to systems, methods, and equipment that provide location and velocity monitoring of both a user's vehicle and another vehicle to avoid collision. The examples are applicable for using on-board telematics units to process that information and provide additional information based thereon such as the probability of collision. In some examples, if the chances of collision are high based on information received, warnings may be given to the vehicle's user. Based on these warnings, the user may take evasive maneuvers to reduce the probability of collision and prevent it. In other examples, if the chances of collision are high, the vehicle may decelerate without prompting from the user to minimize the impact of the collision. Any emergency reporting by the telematics unit, e.g. if a collision still occurred, may be enhanced with the relative location and velocity data from some interval the prior to emergency.
