Method and device for indicating liquid volume in a tank
DCFirst Claim
1. A system for determining a level of a liquid present in a storage container in an automobile, the system comprising:
- a liquid level sensor for determining a preliminary liquid level of the liquid stored in the storage container;
a vehicle speed sensor for determining the automobile'"'"'s speed;
a transmission gear selection sensor for determining a transmission gear position of a transmission of the automobile; and
a processor for receiving input signals from the liquid level sensor, the vehicle speed sensor and the transmission gear selection sensor for modifying the preliminary liquid level to arrive at a final liquid level indication of the liquid present in the storage container when the automobile'"'"'s speed is equal to zero, the automobile transmission gear is in park position, and the preliminary liquid level exceeds a predetermined threshold.

Abstract
A system for determining a level of a liquid present in a storage container in an automobile is disclosed. The system has a liquid level sensor for determining a preliminary liquid level of the liquid stored in the storage container, an ignition key position sensor for determining an ignition position, a vehicle speed sensor for determining the automobile'"'"'s speed, a transmission gear selection sensor for determining a transmission gear position of a transmission of the automobile, and a processor. The processor receives input signals from the liquid level sensor, ignition key position sensor, the vehicle speed sensor and the transmission gear selection sensor for calculating the level of the liquid in the storage container.
