Autonomous braking systems are prevalent in mid/upper-mid range vehicles today. The major drawback: acute boundary condition during which the system will function. Adaptive Range LIDAR System contains 3 DOF stabilized LIDAR sensors which calculate beam convergence as a function of distance, considering multiple obstacles ahead of it. Apart from the other systems that detect objects/obstacles from a stationary point of reference, ARLS determines the velocity of the obstacle with respect to the ground point of reference and computes most optimum brake effort curve. The brake curves are alike for every situation, as it is dynamic in nature, hence, additional electronics ensure physical curve tracing by manipulating the braking circuitry, or in some vehicles, by providing feedback to the Electronic Brakeforce Distribution Systems. Simulations show that since the ARLS uses actual velocities of the test vehicles with respect to the ground, chances of error are low, as the system constantly tracks the velocities of multiple vehicles ahead, and removes any possibility of rear end collisions. Also, since the brake effort curve is dynamic with respect to time, rigorous braking is not imposed on the passenger, and that the retardation is smooth and well distributed in time.
