Electronic device for installation in a motorized vehicle that warns of acceleration or deceleration

A safety device for vehicles that includes lighting devices independent of the conventional brake light system, aimed at alerting a driver who is moving behind a vehicle that has the device installed with respect to the acceleration or deceleration of the latter, in order to reduce rear-end accidents, where the lighting devices include at least one acceleration light (4) and one deceleration light (5) that are arranged in a visible location at the rear of the vehicle, said device comprising:

• a magnet (2) inserted in a rotating mechanism (3) that is related to the movement of a vehicle;
• a sensor (1) configured to be activated when said magnet (2) approaches said sensor (1);
• a microcontroller coupled to the sensor (1) and to at least one acceleration light (4) and at least one deceleration light (5);
• and
• a voltage selector configured to so that the device is used with either 12V or 24V DC batteries.

A method of operating a vehicle safety device that includes lighting devices independent of the conventional brake light system, aimed at alerting a driver who is moving behind a vehicle that has the device installed, with respect to the acceleration or deceleration of the latter, in order to reduce rear-end accidents, where the lighting devices include at least one acceleration light (4) and one deceleration light (5) that are arranged in a visible location at the rear of the vehicle, said method comprises the steps of:

• activating a sensor (1) when a magnet (2) inserted in a rotating mechanism (3) approaches said sensor, wherein said rotating mechanism (3) is related to the movement of the vehicle;
• receiving at a microcontroller signals generated by the sensor (1), wherein said microcontroller is coupled to said sensor (1);
• detecting at said microcontroller an increase or a decrease in a time lapse between the signals generated by the sensor (1) and determining a vehicle acceleration or deceleration based on said detection;
• and
• sending a deceleration signal to a first pin of a Screw (X5) terminal in order to turn on at least one deceleration light (5) coupled to said Screw (X5) terminal or sending an acceleration signal to a second pin of the Screw (X5) terminal in order to turn on at least one acceleration light (4) coupled to said Screw (X5) terminal.
