Abstract: A remote-controlled electric golf bag cart has a remote control, a support frame, an antenna set and a control module. The remote control transmits a distance measurement signal. The support frame has a wheel assembly, a golf bag stand and a motor assembly mounted thereon. The antenna set and the control module are mounted on the support frame. The antenna set receives the distance measurement signal. The control module determines an orientation and a distance of the remote control according to the distance measurement signal received by the antenna set, and drives the motor assembly to move the support frame forward toward the remote control, making the support follow a user having the remote control and preventing other in-field persons and obstacles from affecting the support frame to follow the remote control.

Abstract: A system for monitoring a vehicle and a method for monitoring a vehicle are provided. The system includes a digital signal processor, a plurality of monitoring devices, and an event recorder. The digital signal processor measures the speed of the vehicle to generate measurement data, and analyzes the measurement data to obtain monitoring instruction corresponding to the speed of the vehicle. The monitoring device actuates at least one of the monitoring devices according to the monitoring instruction output by the digital signal processor to generate monitoring data. The event recorder receives the monitoring data output and displays and records the monitoring data. Therefore, the present invention provides an all-directional security system and generates a variety of monitoring mechanism according to the speed of the vehicle, so as to achieve an improved monitoring effect.
