Abstract

A powertrain optimization device and method that compares a predicted performance of customer-selected vehicle components to a customer-selected optimization goal. The optimization goal is used to determine dynamic performance thresholds. The method compares gradability at cruise, gradability at peak torque, engine speed, and startability to the dynamic thresholds to determine whether the vehicle performance will be satisfactory. The customer selections of vehicle components, selections of optimization goals, and any acknowledgements of failed performance checks are stored for later use.

Claims

1. A system for verifying use data of a configured powertrain, the system comprising:

one or more computing devices configured to enable configuration of a powertrain, the one or more computing devices configured to;

receive a selection of one or more specification values representing vehicle components;

receive information regarding an expected use of the vehicle;

receive a selection of an optimization goal;

cause display of one or more rear axle ratios compatible with the one or more specification values, along with an indication of which of the one or more rear axle ratios meet the selected optimization goal;

receive a selection of a rear axle ratio; and

cause the powertrain to be configured according to the selection of the one or more specification values and the selection of the rear axle ratio received by the computing device; and

a vehicle comprising;

the configured powertrain; and

an electronic control unit (ECU) configured to;

obtain use data comprising at least one of vehicle speed data and engine speed data; and

output the obtained use data for comparison to the information regarding the expected use of the vehicle for determining whether actual operation of the vehicle is consistent with the information regarding the expected use of the vehicle.

2. The system of claim 1, wherein the one or more computing devices are further configured to:

display a prompt in response to determining that the selected rear axle ratio does not meet the selected optimization goal; and

record a response to the prompt.

3. The system of claim 1, wherein the information regarding an expected use of the vehicle includes information regarding an expected gross combined weight and an expected cruise speed.

4. The system of claim 1, wherein the information regarding an expected use of the vehicle includes information regarding an application.

5. The system of claim 1, wherein the one or more computing devices are further configured to:

determine a set of optimization goals based on the specification values and the information regarding the expected use of the vehicle; and

present the set of optimization goals.

6. The system of claim 1, wherein the one or more computing devices are further configured to store the selection of one or more specification values, the information regarding the expected use, and the selection of the optimization goal in an order record.
