Abstract:
A vehicle speed control system using wireless communications comprising:a driving state detecting unit for detecting steering angle, vehicle speed, throttle valve opening, brake operation, and turn signal operation, and outputting corresponding signals; a transmitter/receiver for outputting low-strength signals containing information of a speed limit and a range of the speed limit; an electronic control unit for receiving the signals of the transmitter/receiver and establishing an ISA mode if necessary, determining if a present driving state corresponds to a first driving state using the signals of the driving state detecting unit, determining if the driver has performed deceleration operations, and performing control into the first driving state if needed; an engine control unit for outputting signals for control of the throttle valve opening according to control signals of the electronic control unit; a throttle valve electronic control unit for receiving the signals output from the engine control unit and outputting electrical signals to a throttle valve to control an opening degree of the throttle valve; and a display for displaying a present mode and a vehicle state according to the control signals of the electronic control unit.
