A method of controlling access to an interior of a vehicle from outside the vehicle using an access door includes generating a digital key signal via a mobile device owned by a user of the vehicle. The method also includes receiving a digital key signal from the mobile device via a virtual key control module (VKCM) and transmitting a signal indicative of the received digital key signal to a vehicle controller. The method additionally includes detecting, via an ultrasonic sensing device, a presence of a vehicle user external to the vehicle within a predetermined proximity of the access door. The method also includes communicating, via the ultrasonic sensing device, the detected presence of the vehicle user to a vehicle controller. Further, the method includes commanding the mechanism to unlock the access door via the vehicle controller in response to the received digital key signal and the detected presence of the vehicle user. 一种使用进入门控制从车辆外部进入车辆内部的方法，包括经由车辆用户所拥有的移动设备生成数字钥匙信号。该方法还包括经由虚拟钥匙控制模块(VKCM)从移动设备接收数字钥匙信
