Embodiment Construction

[0047] The following description is merely exemplary in nature and is not intended to limit the disclosure, application or uses.

[0048] refer to figure 1 , depicts an exemplary schematic diagram of a vehicle system, generally indicated by reference numeral 10 , which will now be described. The vehicle system 10 in this example is shown as a light duty pickup truck with the capacity to transport multiple occupants and hundreds of pounds or kilograms of cargo in the truck bed. In one example of the present invention, vehicle system 10 also includes a trailer (not shown) attached to the rear of vehicle system 10 , thereby providing the ability to increase the weight capacity of vehicle system 10 . In another example of the present invention, the primary purpose of the vehicle system 10 is to transport passengers, such as a school bus or bus, which is constantly picking up and dropping off passengers. Thus, the ability of a vehicle system to have up to thousands of pounds of a...

Abstract

A method for estimating vehicle system mass includes a plurality of steps including a first step of providing a vehicle system having at least a powertrain and a vehicle control module. Three different quality estimates are assigned, with the last quality estimate being the most accurate. The mass estimate is used in vehicle control module calculations for vehicle control parameters in the event of vehicle weight changes.

Description

technical field [0001] The present disclosure relates to a method of estimating the real-time quality of a vehicle, and more particularly, to a method of estimating the real-time quality of a vehicle using existing hardware in the vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] Determination of vehicle mass is important to the efficient operation of today's vehicles, especially in efficient light and heavy trucks, increasingly capable autonomous vehicles, and the growing development of electric vehicles. For example, vehicle mass is an input consideration for algorithms for proper gear change control in transmissions with stepped gear or motor torque output control for electric vehicles. Vehicle mass can also be used by various vehicle controllers in anti-lock braking systems, intelligent vehicle / highway systems, and fleet managemen...
