TL;DR: The utility model relates to a car safety technical field especially relates to an automobile collision avoidance system including information collection system, information processing system, alarm system and actuating mechanism as discussed by the authors.
Abstract: The utility model relates to a car safety technical field especially relates to an automobile collision avoidance system Including information collection system, information processing system, alarm system and actuating mechanism, information processing system calculates the safe distance that the current speed of a motor vehicle should keep according to the afferent information data of information collection system to execution unit contrasts with the measured distance through the judgement, and then control actuating mechanism makes corresponding action Carry out audio alert when being less than safe distance with the place ahead vehicle or rear vehicle, still not having under emergency reaction's the condition being less than safe distance minimum navigating mate, start the brake or with higher speed the executor make the automobile body with higher speed or slow down, still can start simultaneously when necessary and turn to the executor and make the automobile body turn to, until breaking away from the alarm, effectively avoid knocking into the back and the danger of being knocked into the back

TL;DR: In this article, a braking system consisting of an electronic vacuum booster, an electric vacuum booster controller, an original vehicle anti-skid brake system (ABS) and braking branch pumps is presented.
Abstract: The utility model relates to a braking system with an electronically-assisted braking function. The braking system comprises an electronic vacuum booster, an electronic vacuum booster controller, an original vehicle anti-skid brake system (ABS) and braking branch pumps, wherein the electronic vacuum booster comprises an electromagnetic iron core in a vacuum valve, an electromagnetic coil and an electric casing; atmospheric valves are arranged in the electromagnetic iron core and the electric casing, and are in close contact with a rubber valve seat; a gap is reserved between the electric casing and the rubber valve seat; the electronic vacuum booster controller is preset with threshold values of change rates of a braking pressure, emergency braking auxiliary mode working time and a practical braking pressure, and is used for receiving a desired braking pressure, the practical braking pressure and a driver braking signal transmitted by a driving assisting system from a vehicle-mounted controller area network (CAN) bus, comparing various received signals with preset threshold values, making judgment and outputting current to the electromagnetic coil; the original vehicle ABS is connected with a braking main cylinder of the electronic vacuum booster through a pipeline; and the braking branch pumps are all connected with the original vehicle ABS through pipelines. The braking system can be widely applied to driving assisting systems such as a self-adaptive cruising control system, a walking-stopping cruising system, an active collision avoidance system, an emergency braking assisting system and the like.

Abstract: The paper introduces a proposal of an Autonomous Navigation System for Unmanned Surface Vessels. The system architecture is presented with a special emphasis on collision avoidance and maneuver auto-negotiation. For the purpose of maneuver auto-negotiation, the concept of multi-agent systems has been applied. The algorithm developed for the task of collision avoidance is briefly described and the results of the simulation tests, confirming the effectiveness of applied method, are also given. Presented outcomes include solutions of test scenarios from the perspectives of different ships taking part in the considered situations, confirming the applicability of the collision avoidance algorithm in the process of maneuver auto-negotiation.
