System and method for providing information to first responders after a vehicle collision

A method for providing information about a vehicle involved in a collision, the method comprising:

• receiving an excitation signal using an antenna module of a sensing device, wherein the sensing device is affixed to the vehicle;
• harvesting energy from the excitation signal using a power module of the sensing device, wherein the power module includes a radio-frequency (RF) energy harvesting circuit;
• performing a measurement using a sensor module of the sensing device in response to receiving the excitation signal;
• transmitting the measurement using the antenna module of the sensing device;
• and
• jettisoning the sensing device from the vehicle in response to identifying a vehicle collision condition.

A system for providing information about a vehicle involved in a collision, the system comprising:

• an external transceiving device, wherein the external transceiving device includes a transceiving device display, a transceiving device communication system, and a transceiving device controller in electrical communication with the transceiving device display and the transceiving device communication system, wherein the transceiving device controller is programmed to:
• transmit an excitation signal using the transceiving device communication system;
• receive one or more response messages using the transceiving device communication system;
• stitch the one or more response messages to form a processed response message, wherein to stitch the one or more response messages, the transceiving device controller is programmed to temporally align frames or sections of two or more response messages to form the processed response message;
• and
• display the processed response message using the transceiving device display;
• and
• a sensing device affixed to the vehicle, wherein the sensing device includes a sensor module configured to perform measurements of one or more conditions of the vehicle, an antenna module configured to transmit and receive radio-frequency (RF) signals, a power module configured to provide power to the sensing device, and a sensing device controller in electrical communication with the sensor module, the antenna module, and the power module, and wherein the sensing device controller is programmed to:
• receive the excitation signal from the external transceiving device;
• perform a measurement using the sensor module in response to receiving the excitation signal;
• and
• transmit the measurement to the external transceiving device using the antenna module;
• and
• a vehicle communication system in electrical communication with a vehicle controller, wherein the vehicle controller is programmed to:
• wirelessly transmit a vehicle state dataset to the sensing device using the vehicle communication system, wherein the vehicle state dataset includes one or more status metrics of various vehicle systems.
