“…For many reasons, such as driver acceptance of the system and legal requirement that the system itself must not cause hazards, the decision making was a crucial part of the system. Najmi et al 11 dealt with some aspects of an embedded infrared system devoted to automotive obstacle detection and avoidance to improve the detection-range accuracy by taking into account the size and cost constraints needed in the automotive field. Lee et al 12 suggested a probabilistic collision risk assessment method for a potential collision vehicle in an occluded area which estimated the collision risk, and proposed the probabilistic collision risk assessment method in several occlusion scenarios with real traffic, including an alleyway, a merging lane, and blockage by a bulky vehicle.…”

Traffic congestion has been the most tiresome encounter since the initiation of vehicle advancement. Many braking systems have been designed by researchers in previous studies, but this study is primarily focused on a braking system that is affordable to all because it is based on a simple Arduino-controlled system. Moreover, it is assistive on everyday traffic commutes rather than highway driving, which is relatively rare for normal drivers. As more and more vehicles crowd the roads, the more problematic it is becoming for the drivers, which is ultimately leading toward increment in the frontal car accidents. In this study, an electro-mechanical braking system has been deployed that assists the driver during the jam-packs by measuring the exact distance between the driven and forthcoming vehicle or any obstacle by applying the brakes without the driver pressing the brake pedal to ultimately bring the vehicle to a halt without any fear of vehicle collision. An ultrasonic sensor is used at the front bumper grille that measures the distance between the two closing vehicles. The total time to halt the vehicle has been calculated as 0.6 s, while the critical distance for the sensor has been set as 1-m. Furthermore, the stepper motor drivers are set at the maximum current output of 2.5 amps with a 12-volt battery connected in parallel to the motors. It is found that theoretical stopping time is in good agreement with the experimental stopping time to completely press the brake pedal and halt the car.

Distance measurement under difficult environmental conditions is essential for automotive systems. Vehicles in the near future are intended to drive autonomously or at least to give the driver as much assistance as possible to increase safety and comfort. Distance measurement systems already exist that allow the implementation of systems such as collision warning and autonomous intelligent cruise control. The radar distance measurement used for this purpose works under arbitrary weather conditions, where other measurement principles such as laser, optical, infrared or ultrasonic systems may fail. Microwave radar is the most important measurement method for automotives. Ultrasonic systems serve as a parking aid. Other systems such as video-based systems are under development for autonomous driving within a lane. This chapter describes several distance measurement systems and their implementation in automobiles.
