英文摘要 | In this study, an ultrasound sensor that was put on a smart wheeled mobile robot (SWMR) was used to detect parking space environment, simulate drivers’ parking strategy, and complete roadside parking and reverse parking. In order to achieve automatic parking, the functions of the system included searching for suitable parking space, detecting adjacent obstacles, planning the parking path, producing pulse width modulation (PWM) signals to drive servo motors, and completing steering control to achieve roadside parking. Once the ultrasonic sensors detect enough parking space, the SWMR can automatically control the servomotors of two wheels to turn around, go straight, move backward and stop, until the car is placed well in the target parking space. According to the experimental results, this study indeed can effectively simulate the actual parking situations, shorten parking safety spacing, and complete automatic parking. |
