The invention provides a vehicle guidance system, an onboard device and a ground device. The onboard device includes: a guidance control unit that performs guidance control; a transmission control unit that performs transmission control to transmit the first wave out of the vehicle when the guidance control is executed; and a reception control unit that performs reception and control of the secondwave corresponding to the first wave, the ground device includes: a plurality of ground receivers, and at least one ground wave receiver provided at the first position and the second position corresponding to the widthwise ends of the entry provided in the predetermined area for receiving the first wave; and multiple first ground wave transmitters, which are arranged in a manner corresponding tothe multiple ground wave receivers respectively, and receiving the first wave according to at least one of the multiple ground wave receivers, and transmitting the second wave at least towards the direction opposite to the vehicle entry direction of the predetermined area, and the guidance control unit determines the entry route toward the entry based on the change in the signal level of the second wave received in the reception control corresponding to the position of the vehicle.
本发明提供车辆引导系统、车载装置以及地面装置,车载装置具备:引导控制部,执行引导控制;发送控制部,在引导控制的执行时,执行向车辆外发送第1波的发送控制;以及接收控制部,执行接收与第1波对应的第2波的接收控制,地面装置具备:多个地面收波器,在与设置于规定区域的进入口的宽度方向的两端对应的第1位置以及第2位置各设置至少1个地面收波器,接收第1波;以及多个第1地面发波器,以与多个地面收波器分别对应的方式设置,根据多个地面收波器中的至少1个接收第1波,至少向车辆朝规定区域的进入方向的相反方向发送第2波,引导控制部基于在接收控制中接收的第2波的信号电平的与车辆的位置对应的变化,来决定朝进入口的进入路线。
