Adaptive Cruise Control

As part of this project, I developed an adaptive cruise controller with automatic steering control. The haptic wheel was used as a steering wheel for the simulated vehicle on the simulink graphics software. The position of the wheel obtained using quadrature decoding is used to determine the angle of the front wheels. By toggling one of the DIP switches, we can enable or disable the ACC system. When disabled, we can manually control the speed of the vehicle using the potentiometer. When ACC is enabled, we use the first 8 DIP switches to set the speed of the vehicle. As mentioned previously, ACC performs both velocity and position control. When there is a lead vehicle within the specified safe distance ahead of our vehicle, position control is enabled. Otherwise, velocity control is enabled. The automatic steering control is used to automatically align the vehicle at the center of the road while performing any speed or velocity control. The project was modeled entirely in simulink, auto- code generation was utilized to obtain the C code processed within S32K144.
