IN-VEHICLE ALERT OF CLOUD POINT IN ENGINE DIESEL FUEL
First Claim
1. A method for receiving in-vehicle information regarding diesel fuel cloud point condition, the method comprising:
- establishing communication between a telematics unit in a vehicle and i) a global positioning system device, ii) a database at a call center or operatively connected to the telematics unit, and iii) a cloud point monitoring device in the vehicle;
receiving, at the telematics unit from at least one of i, ii, iii or an in-vehicle sensor, information pertaining to vehicle location, cloud point, and ambient temperature;
determining from the information whether fuel in a fuel system of the vehicle is reaching cloud point or will reach cloud point within a given time period; and
transmitting an in-vehicle alert when the fuel in the vehicle fuel system is reaching cloud point or will reach cloud point within a given time period.

Abstract
The disclosure relates to a method for receiving in-vehicle information regarding diesel fuel cloud point condition. The method includes establishing communication between a telematics unit in a vehicle and i) a global positioning system device, ii) a call center including a database, and iii) a cloud point monitoring device in the vehicle. The telematics unit receives from at least one of i, ii, or iii, information pertaining to vehicle location, cloud point, and ambient temperature. The telematics unit determines from the information whether fuel in a fuel system of the vehicle is reaching cloud point or can reach cloud point within a given time period. The telematics unit then transmits an in-vehicle alert when the fuel in the vehicle fuel system is reaching cloud point or can reach cloud point within a given time period. The disclosure also relates to a system for performing the method.

9. A system for generating in-vehicle information regarding a diesel fuel cloud point condition, the system comprising:
-
a telematics unit in a vehicle; a global positioning system device configured to transmit vehicle location information to the telematics unit; a database, operatively connected to the telematics unit or at a call center, configured to transmit stored information to the telematics unit; a cloud point monitoring device in the vehicle configured to measure a cloud point temperature and transmit such measurement to the telematics unit; and a driver information center in the vehicle configured to receive an alert when the telematics unit recognizes, based on the received information and measurements, that the fuel in a fuel system of the vehicle is reaching the cloud point or can reach cloud point within a given time period. - View Dependent Claims (10, 11, 12, 13)
