Abstract
A system for detecting the locked status of a vehicle having an electrical power door lock system includes a status transmitter configured to transmit a signal indicating when the vehicle is in a locked status having at least an input that is connected to the vehicle system to detect a voltage indicating a command to lock all vehicle doors. A remote receiver is responsive to the status transmitter and is configured to indicate whether the vehicle is in a locked status based upon the transmitter signal.
Claims9
A system for detecting locked status of a vehicle, said vehicle having an electrical power door lock system, said system for detecting comprising:
- a status transmitter configured to transmit a signal indicating said vehicle is in a locked status and having first input for coupling a lock voltage from said power door lock system, said lock voltage representative of a command to lock all vehicle doors;
- and
- a remote receiver responsive to said status transmitter and configured to indicate whether said vehicle is in the locked status based upon said signal;
- wherein said status transmitter further comprises a voltage detector coupled to said first input and configured to detect the polarity of said lock voltage;
- a second input to said status transmitter for coupling an unlock voltage from said power door lock system, said unlock voltage representative of a command to unlock all vehicle doors;
- and
- wherein said voltage detector is coupled to said second input and is configured to detect the polarity of said unlock voltage.
A system for detecting locked status of a vehicle having a power door lock subsystem, said system for detection system comprising:
- a transmitter comprising:
- first and second inputs configured to be respectively connected to first and second leads in said power door lock subsystem, said first and second inputs, when so connected, respectively comprising a lock voltage representing a command to said power door lock subsystem to lock all vehicle doors and an unlock voltage representing a command to said power door lock subsystem to lock all vehicle doors;
- a voltage detector responsive to said first and second inputs and configured to detect the polarity of said lock and unlock voltages and outputting a signal representing said polarity;
- a transmitter controller configured to receive said signal and to output a status signal representing either one of a locked status and an unlocked status of said vehicle;
- a radio frequency module for wirelessly transmitting said status signal.
