摘　　要：文中设计并实现了一种超声传感器系统,主要应用于在自动泊车系统中汽车对泊车环境的感知。根据超声回波的特点来设计硬件电路以及编制相应的软件程序,增强了超声传感器检测环境信息的灵敏度和数据的稳定性。该系统可提高汽车自主驾驶系统对泊车环境的感知能力,是汽车主动安全功能的关键部分,具有很好的应用价值。An ultrasonic sensor system has been designed and realized in this paper, which is mainly used to get the parking information of the environment in automatic parking system. Based on the characters of ultrasonic echoed signals, the circuit and software have been designed, with which the sensitivity and the stability of the ultrasonic sensor are enhanced. The system can improve the a bility of auto-driving system in getting parking information of the environment, is an important part of the auto-active security and can be widely used.
