Abstract

Autonomous short distance manoeuvring with optimal acceleration for avoiding or mitigating inevitable side and read end collision is a highly time sensitive design and technique that actively monitors, instantaneously senses inevitable or imminent side impact and rear end collision, alert or warns the driver and if the driver not available or doesn'"'"'t react or if the drivers sensing and reaction time is not sufficient the present system according to scenarios acts in the right time to takes control of the vehicle'"'"'s with autonomous optimal acceleration and steering followed by deceleration or restoring the control back to driver based on scenarios thereby mobilising the vehicle to short distance according to critical situations thus efficiently utilising the space around the vehicle to manoeuvre, locate or position the vehicle ultimately to avoid or mitigate the side impact and read end collision. The present system particularly helps in efficiently utilising the space or environment around the vehicle in critical situations ultimately to avoid or mitigate Imminent and inevitable side impact and rear end collision. The system smartly senses, perform context aware computing in a closed loop processing manner thereby autonomously and optimally accelerate and steer the vehicle to right position ultimately to avoid or reduce the side and read end collision thus assist in overcoming or mitigating critical situations for protecting the vehicles, occupants, pedestrians and other objects around or on the way. Also according to design, configurations and scenarios the system instantaneously restores or transfers the control back to the driver after the vehicle overcomes the critical situation or restores the vehicle position. In critical situations SAAAMS performs sensing, warns or alerts, performs pre computing & set ready to control the vehicle'"'"'s acceleration prior to critical situation, current computing for controlling the vehicle'"'"'s acceleration during critical situation, post computing to either stop or transfer the control back to the driver after overcoming the critical situation all accordingly to design, configuration and scenarios. The present system utilise smart and adaptive closed loop processing algorithm with predetermined and tested correlation table parameters to instantaneously check and compare the effects between predetermined and tested real world scenarios to the actual real world scenarios for actively sensing, computing and controlling the vehicle accordingly to mitigate the critical situations. In case of vehicles available in both front and rear end and if the rear end vehicle is about to collide the system actively senses, instantaneously manoeuvre the vehicle ultimately to efficiently utilises the space available between the own vehicle and front end vehicle thereby to provide space for the rear end vehicle that is about to collide to either stop or in extreme situations mitigates the severity of the collision.
