Abstract

The present application generally relates to a method and apparatus for obtaining incident related data in a motor vehicle. In particular, the system is operative to determine a vehicle to vehicle contract event or near contact event, transmit a request for data, such as video, numeric, and telemetry data, from proximate actors via V2X communications channel, or to request the data be transmitted to a network storage location.

First claim

What is claimed is:

1. An apparatus for collecting vehicle incident related data within a host vehicle comprising:
a first camera, within the host vehicle, having a memory for buffering a first video file;
an airbag deployment sensor, within the host vehicle, for generating a control signal in response to an airbag deployment within the host vehicle;
a non-volatile memory for storing the first video file and a second video file;
a transmitter for transmitting a request for data from the host vehicle to a proximate vehicle via a vehicle to vehicle communications network;
a receiver, within the host vehicle, for receiving the second video file from the proximate vehicle via the vehicle to vehicle communications network wherein the second video file is captured by a second camera with the proximate vehicle; and
a processor, within the host vehicle, for receiving the control signal, for generating the request for data in response to the control signal, for receiving and storing the first video file and the second video file on the non-volatile memory, the processor being further operative to estimate a time to collision and to generate the request for data in response to the time to collision.

2. The apparatus of claim 1 wherein the second video file is received from an infrastructure camera in response to the request for data.

3. An apparatus comprising:
an airbag deployment sensor within a host vehicle for detecting an airbag deployment event;
a processor within the host vehicle for generating a request for data in response to the airbag deployment event, the processor being further operative to estimate a time to collision and to generate the request for data in response to the time to collision;
a transmitter, within the host vehicle, for transmitting the request for data to a proximate vehicle via a vehicle to vehicle communications network;
a receiver, within the host vehicle, for receiving a received data including a first video from a proximate vehicle via a vehicle to vehicle communications network wherein the first video is captured by a first camera with the proximate vehicle; and
a memory within the host vehicle for storing the received data including the first video.

4. The apparatus of claim 3 wherein the memory is a non-volatile memory.

5. The apparatus of claim 3 further comprising a second camera within the host vehicle for capturing a second video and wherein the second video is stored in the memory in response to the airbag deployment event.

6. The apparatus of claim 3 wherein the airbag deployment sensor is an inertial sensor and the airbag deployment event is determined in response to a change in a measured inertia.

7. The apparatus of claim 3 wherein the request for data is transmitted via a wireless communications channel.

8. The apparatus of claim 3 wherein the received data includes the first video captured by a camera on the proximate vehicle.

9. A method comprising:
detecting an airbag deployment event within a host vehicle;
generating, by a processor within the host vehicle, a request for data in response to the detection of the airbag deployment event, the processor being further operative to estimate a time to collision and to generate the request for data in response to the time to collision;
transmitting, by a transmitter, the requested for data via a wireless communications network to a proximate vehicle;
receiving, by a receiver, a received data including a first video file from the proximate vehicle via the wireless communications network wherein the first video file is captured by a first camera with the proximate vehicle; and
storing, in a non-volatile memory, the received data including the first video file.

10. The method of claim 9 wherein the airbag deployment event is detected by an airbag deployment sensor.

11. The method of claim 9 further comprising capturing a second video file, by a second camera within the host vehicle, and a vehicle telemetry data in response to the airbag deployment event and storing the second video file and the vehicle telemetry data in the non-volatile memory.

12. The method of claim 9 wherein the airbag deployment event is detected in response to a change of inertia measured by an inertial sensor.
