Abstract:
1. A vehicle deceleration warning apparatus, comprising: an ignition monitoring module, being electrically connected to an ignition signal generation module of the vehicle, receiving a first voltage signal generated by the ignition signal generation module, converting the received first voltage signal into a second voltage signal, and then outputting the second voltage signal; a first microprocessor module, electrically connected to the ignition monitoring module, performing a calculation based on a frequency of the second voltage signal output by the ignition monitoring module, deriving an encoded first display control signal when the frequency of the second voltage signal descends, and generating an encoded third display control signal after the frequency of the second voltage signal remains in an idle running state of the vehicle for a time interval; the first microprocessor module also generating an encoded second display control signal to indicate turning; a wireless transmitting module, being electrically connected to the first microprocessor module, receiving the first, second, and third display control signals, and transmitting the first, second, and third display control signals to a remote end by wireless transmission; a wireless receiving module, being disposed at the remote end, receiving the first, second, and third display control signals transmitted by the wireless transmitting module and decoding the first, second, and third display control signals; a second microprocessor module, being electrically connected to the wireless receiving module, and receiving the decoded first, second, and third display control signals; a display driving module, being electrically connected to the second microprocessor module, generating a first display driving signal according to the first display control signal received by the second microprocessor module, generating a second display driving signal according to the second display control signal, and generating a third display driving signal according to the third display control signal; and a display module, being electrically connected to the display driving module, generating a corresponding warning light according to the first display driving signal, the second display driving signal, or the third display driving signal output by the display driving module.
