Abstract:
A fuel measurement system and method that can determine the fuel level in a vehicle fuel tank, even when the fuel is sloshing, splashing, or experiencing other dynamic conditions. Generally speaking, the system and method use different fuel measuring techniques to address different fuel tank conditions. For example, during normal conditions a traditional fuel level sensor may be used. During dynamic conditions, such as when the vehicle is experiencing significant acceleration, maneuvering, inclination, yaw rate, etc., the system may employ other measuring techniques that are better suited to address such an environment. One measuring technique that may be used is a consumption-based technique that uses fuel usage signals from one or more fuel injector sensor(s) to determine the amount of fuel consumed, and then subtracts that amount from a previous fuel level reading.
