Sistem Penghindar Tabrakan Frontal Berbasis Logika Fuzzy

Abstract: About 10% of collisions resulting in death is due to frontal collision. Head-on Collision Avoidance System (HCAS) is a device that can prevent a frontal collision by means of braking or evasive. Two ultrasonic sensors are used to monitor the vehicles in front and to the right. Two distances are observed by sensors, then become input for decision making system based on fuzzy logic. This decision-making system output is the vehicle forward, stop, or evasive movement. Simulation result using a remote control car proves that the decision making system designed with fuzzy logic can work with a success rate of over 90%.

A signals processing and big data framework for Monte Carlo aircraft encounters

Abstract: Developing a collision avoidance system that can meet safety standards required of commercial aviation is challenging A dynamic programming approach to collision avoidance has been developed to optimize and generate logics that are robust to the complex dynamics of the national airspace The current approach represents the aircraft avoidance problem as Markov Decision Processes and independently optimizes a horizontal and vertical maneuver avoidance logics This is a result of the current memory requirements for each logic, simply combining the logics will result in a significantly larger representation The “curse of dimensionality” makes it computationally inefficient and infeasible to optimize this larger representation However, existing and future collision avoidance systems have mostly defined the decision process by hand In response, a simulation-based framework was built to better understand how each potential state quantifies the aircraft avoidance problem with regards to safety and operational components The framework leverages recent advances in signals processing and database, while enabling the highest fidelity analysis of Monte Carlo aircraft encounter simulations to date This framework enabled the calculation of how well each state of the decision process quantifies the collision risk and the associated memory requirements Using this analysis, a collision avoidance logic that leverages both horizontal and vertical actions was built and optimized using this simulation-based approach

System and method for emergency collision avoidance

Abstract: The invention provides a system and a method for emergency collision avoidance, and relates to the field of vehicle safety control. The emergency collision avoidance system comprises a trajectory prediction unit, a determining unit, a calculating unit, and a control unit. The trajectory prediction unit is used to continuously predict movement trajectory of a vehicle and at least one target objectaround the vehicle in future preset time. The determining unit is used to continuously determine whether the vehicle and the target object have collision risk according to the movement trajectory of the target object and the movement trajectory of the vehicle. The calculating unit is used to continuously calculate at least one collision avoidance path of the vehicle according to the movement trajectory of the vehicle and the movement trajectory of the target object. The control unit is used to change a travelling state of the vehicle to make the vehicle travel along the collision avoidance path according to a result calculated by the calculating unit. Using the system and the method for emergency collision avoidance can accurately and rationally schedule a collision avoidance path in realtime, so as to avoid collision to the maximum extent under the condition of ensuring safety of the vehicle.
