<p>This invention relates to an automatic control device adapted for preventing rear-end collision of a front motorized vehicle and a rear motorized vehicle running behind the front vehicle. The automatic control device for preventing rear-end collision according to this invention comprises: a microprocessor (100), at least one signal emitter (101), a speed detector (102), at least one signal receiver (103), a brake controller (104) and an accelerator pedal controller (105), in which the at least one signal emitter is installed at the rear end of the front vehicle while the other comprising mechanisms are installed in the rear vehicle. The microprocessor couples separately with the signal emitter, the speed detector, the signal receiver, the brake controller and the accelerator pedal controller so as to transfer and process various signals. When the situation of overspeed is detected by the speed detector, the accelerator pedal controller and the brake controller will be actuated to reduce the fuel supply and apply the brake of the rear vehicle so as to prevent the occurence of rear-end collision.</p> |
