VSI Pro Report: Radar-Based Adaptive Cruise Control

5,000.00

Adaptive Cruise Control (ACC) regulates the longitudinal velocity of a vehicle, based on the kinematics of the host vehicle and the target vehicle. The primary goal of ACC is to apply throttle and brakes in order to match the speed to the target vehicle and keep a certain desired distance and not collide with the target vehicle. VSI Labs built its own ACC by using Open Source Car Control for by-wire control of throttle and braking and Nvidia’s Drive PX2 as a host AV computer. This report explains how to create control algorithms for ACC and implementation of ACC in our research vehicle.
