Vehicle control system

A method comprising:

• measuring an acceleration of a vehicle during movement of the vehicle using a sensor;
• measuring a displacement of the vehicle during the movement of the vehicle using the sensor;
• and
• identifying one or more of an instability condition or a derailment condition of the vehicle using one or more processors, the instability condition identified responsive to the acceleration that is measured being no greater than an acceleration threshold and the displacement that is measured being no greater than a displacement threshold, the derailment condition identified responsive to the acceleration that is measured being greater than the acceleration threshold and the displacement that is measured being greater than the displacement threshold.

A system comprising:

• a sensor means configured to measure an acceleration, a linear displacement, and an angular displacement of a vehicle during movement of the vehicle;
• and
• one or more processors configured to examine the acceleration, the linear displacement, and the angular displacement to identify one or more of an instability condition or a derailment condition of the vehicle, the one or more processors configured to identify the instability condition responsive to the acceleration that is measured being no greater than an acceleration threshold, the linear displacement that is measured being no greater than a linear displacement threshold, and the angular displacement that is measured being no greater than an angular displacement threshold,
• the one or more processors configured to identify the derailment condition responsive to the acceleration that is measured being greater than the acceleration threshold, the linear displacement that is measured being greater than the linear displacement threshold, and the angular displacement that is measured being greater than the angular displacement threshold.
