Abstract:

When a vehicle turns, the front and rear wheels do not have the same forward or backward trajectory. This situation is called the radius difference between inner wheels. The front wheels with the "wheelbase" length and "angle" are different from those of the rear wheels. Road tragedies have occurred due to motorcycle drivers and pedestrians getting caught in a turning truck's swept path width. A novel collision prevention system is presented to prevent the motorcycle drivers or pedestrians from the range of the radius difference between inner vehicle wheels. A steering angle sensor is used to calculate the turning angle of the wheels. According to the different steering angles, when the vehicle is turned, different voltage is output to an Arduino board. The ultrasonic transducers have been used to detect the motorcycle or pedestrians. The results show that a warning system could effectively remind the vehicle driver when the motorcycle or pedestrians are in danger.
