Abstract

Official abstract text for this publication.

A system estimating temperature of a mechanical member of a vehicle once the vehicle has stopped, including: a temperature sensor of a first element of the vehicle, for example a fluid tank; a mechanism estimating air temperature outside the vehicle; a first module estimating temperature of the member when the vehicle is moving; a mechanism storing, while the vehicle is stopped, an outside air temperature, a temperature of the first element, and a temperature of the member; a second module to calculate how long the vehicle has been stopped according to the outside air temperature, the stored temperature of the first element, and the measured temperature of the first element; and a third module to calculate thermal history of temperature variation of the member while the vehicle is stopped, according to the outside air temperature, the stored temperature of the member, and the stoppage time of the vehicle.

First claim

Opening claim text (preview).

The invention claimed is: 1. A system for estimating temperature of a mechanical member of a vehicle after the vehicle is stopped, comprising: a temperature sensor of a first element of the vehicle; a means of estimating temperature of air outside the vehicle; a first module estimating temperature of the member while the vehicle is traveling; a means of storing, while the vehicle is stopped, of an outside air temperature value, a temperature value of the first element, and a temp…
