The invention belongs to the technical field of vehicle auxiliary measurement and specifically provides an energy-saving vehicle distance warning device. The energy-saving vehicle distance warning device comprises a solar panel (1), a storage battery (2), a display (3) and an ultrasonic distance measuring module (4), wherein the solar panel (1) is placed on the roof and electrically connected with the storage battery (2); the output of the storage battery (2) is electrically connected with the display (3) to supply power to the display (3); the display (3) is electrically connected with the ultrasonic distance measuring module (4). The energy-saving vehicle distance warning device solves problems that a driver in the prior art cannot take corresponding device to prevent rear-end collision and the vehicle distance measuring device needs vehicle-mounted power supply. The energy-saving vehicle distance warning device is low in cost, energy-saving and environment-friendly, has a good warning effect to the rear-end collision, and supplies power through solar energy.
