The purpose of the present invention is to accurately guide a vehicle to a parking area without being affected by the environment. A parking guidance apparatus provided at a vehicle includes a reception processor receiving a transmission wave transmitted from a ground apparatus through at least two onboard receivers fixedly provided at different positions at the vehicle, the at least two onboard receivers including a first onboard receiver and a second onboard receiver, an estimation processor estimating a position of the ground apparatus relative to a position of the vehicle in accordance with a time difference between a first timing and a second timing, the first timing at which the transmission wave is received by the reception processor through the first onboard receiver, the second timing at which the transmission wave is received by the reception processor through the second onboard receiver, and a guide processor specifying a parking area in accordance with the position of the ground apparatus estimated by the estimation processor and guiding the vehicle towards the parking area.

    本发明能够不被环境影响地精度良好地向停车区域引导车辆。作为本公开的一个例子的停车引导装置是设置于车辆的停车引导装置,具备:接收处理部,经由在车辆被固定地设置于分别不同的位置的至少2个车上受波器接收从固定地设置于地面的地面装置发送的发送波;推断处理部,基于通过接收处理部经由至少2个车上受波器中的第1车上受波器接收发送波的第1定时与通过接收处理部经由至少2个车上受波器中的与第1车上受波器不同的第2车上受波器接收发送波的第2定时之间的时间差,推断以车辆的位置为基准的地面装置的位置;以及引导处理部,基于通过推断处理部推断的地面装置的位置确定与地面装置对应地设置的停车区域,并朝向该停车区域引导车辆。
