The adaptive braking system was designed by VHDL. It provides pre-crash safety for intelligent vehicle. This module has three sub modules. First, it can detect the distance between front vehicle and our vehicle to keep a constant distance using sensor and operate the brake system if the driver doesn?t decrease the speed of vehicle. Second, it can detect the speed difference between the front wheel of our vehicle to determine the skid and operate the individual brake system if the speed difference is high or low. Third, it can detect the vehicle in the neighboring lane to change the lane instead of applying brake system.
