Abstract

A system for recording data from one or more electronic control units in one or more vehicles includes a data-recorder and a memory. The data-recorder is suitable for communication with an electronic control unit of a vehicle. The memory is in communication with the data-recorder. The memory is used to store configurations of vehicles. The configurations are used to configure the data-recorder to communicate with the vehicle. The memory is also used to store additional code used to configure data acquisition (DAQ) settings of the data-recorder to capture data from the vehicle at a first data-rate when a first trigger-signal transitions to a first state, and capture data from the vehicle at a second data-rate when a second trigger-signal transitions to a second state.

Claims

1. A system for recording data from one or more electronic control units in one or more vehicles, said system comprising:

a data-recorder suitable for communication with an electronic control unit of a vehicle;

a memory in communication with the data-recorder, said memory used to store configurations of vehicles, said configurations used to configure the data-recorder to communicate with the vehicle, said memory also used to store additional code used to configure data acquisition (DAQ) settings of the data-recorder to capture data from the vehicle at a first data-rate when a first trigger-signal transitions to a first state, and capture data from the vehicle at a second data-rate when a second trigger-signal transitions to a second state.

2. The system in accordance with claim 1, wherein the data-recorder captures data simultaneously at the first data-rate and the second data-rate when the second trigger-signal transitions to the second state.

3. The system in accordance with claim 1, wherein the data-recorder determines an on-board synthetic-data parameter based on sampled-data, and the first trigger-signal is based on the on-board synthetic-data parameter.

4. The system in accordance with claim 1, wherein the second trigger-signal occurs a time-interval after the first trigger-signal.

5. The system in accordance with claim 1, wherein the data-recorder determines statistical-data based on sampled-data, said statistical-data characterized as one of a minimum, a maximum, an average, a standard deviation, a variance, a signal-to-noise ratio, and a frequency, and the first trigger-signal is based on the statistical-data.
