Abstract

Methods and devices for determining speed control management settings are provided. A vehicle configuration is obtained, specifying at least a transmission, including a number of gears present in the transmission. One or more speed control management modules, such as progressive shift and/or gear down protection modules, are selected by a customer. One or more default progressive shift limits and a default gear down protection limit are calculated, along with gears for which they are active. Performance of the vehicle using the default speed control management settings is simulated and compared to typical vehicle performance. The customer may alter the speed control management settings within dynamically determined valid ranges. The speed control management settings are used in the manufacture or other configuration of the vehicle for the customer.

Claims

1. A computer-implemented method of configuring a vehicle, the method comprising:

receiving, by a computing device, a vehicle configuration that includes an optimization goal selected by a user and a maximum expected grade;

determining, by the computing device, at least one progressive shift limit or at least one gear down protection shift limit based on the vehicle configuration;

storing, by the computing device in an order data store, the determined at least one progressive shift limit or the determined at least one gear down protection shift limit;

calculating, by the computing device, a valid progressive shift limit range based on the vehicle configuration, wherein the valid progressive shift limit range is calculated by determining which progressive shift limits can provide adequate startability and gradeability performance for the vehicle in view of the maximum expected grade while still meeting the optimization goal;

presenting, by the computing device, the valid progressive shift limit range to a user;

receiving, by the computing device, a selection of at least one progressive shift limit within the valid progressive shift limit range; and

replacing, by the computing device, the determined at least one progressive shift limit with the selected at least one progressive shift limit.

2. The method of claim 1, wherein the vehicle configuration includes a transmission configuration, an engine model, a rear axle ratio, and a tire size.

3. The method of claim 2, wherein the transmission configuration includes a number of gears and a set of gear ratios.

4. The method of claim 1, wherein the vehicle configuration includes a typical cruise speed and typical shift points for each gear of a transmission.

5. The method of claim 1, further comprising:

calculating a valid gear down protection shift limit range based on the vehicle configuration;

receiving a selection of at least one gear down protection shift limit within the valid gear down protection shift limit range; and

replacing the determined at least one gear down protection shift limit with the selected at least one gear down protection shift limit.

6. The method of claim 1, further comprising:

determining, by the computing device, a set of transmission gears for each progressive shift limit in which the progressive shift limit is active, based on the vehicle configuration; and

storing, by the computing device in the order data store, the determined sets of transmission gears.

7. The method of claim 1, wherein determining the at least one progressive shift limit includes retrieving the at least one progressive shift limit from a look-up table based on the vehicle configuration.

8. The method of claim 1, wherein determining the at least one progressive shift limit includes calculating the at least one progressive shift limit based on performance data associated with components identified in the vehicle configuration.

9. A nontransitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by one or more processors of a computing device, cause the computing device to perform actions for configuring a vehicle, the actions comprising:

receiving a vehicle configuration that includes an optimization goal selected by a user and a maximum expected grade;

determining at least one progressive shift limit or at least one gear down protection shift limit based on the vehicle configuration;

storing, in an order data store, the determined at least one progressive shift limit or the determined at least one gear down protection shift limit;

calculating a valid progressive shift limit range based on the vehicle configuration, wherein the valid progressive shift limit range is calculated by determining which progressive shift limits can provide adequate startability and gradeability performance for the vehicle in view of the maximum expected grade while still meeting the optimization goal;

presenting the valid progressive shift limit range to a user;

receiving a selection of at least one progressive shift limit within the valid progressive shift limit range; and

replacing the determined at least one progressive shift limit with the selected at least one progressive shift limit.

10. The computer-readable medium of claim 9, wherein the vehicle configuration includes a transmission configuration, an engine model, a rear axle ratio, and a tire size.

11. The computer-readable medium of claim 10, wherein the transmission configuration includes a number of gears and a set of gear ratios.

12. The computer-readable medium of claim 9, wherein the vehicle configuration includes a typical cruise speed and typical shift points for each gear of a transmission.

13. The computer-readable medium of claim 9, wherein the actions further comprise:

calculating a valid gear down protection shift limit range based on the vehicle configuration;

receiving a selection of at least one gear down protection shift limit within the valid gear down protection shift limit range; and

replacing the determined at least one gear down protection shift limit with the selected at least one gear down protection shift limit.

14. The computer-readable medium of claim 9, wherein the actions further comprise:

determining a set of transmission gears for each progressive shift limit in which the progressive shift limit is active, based on the vehicle configuration; and

storing, in the order data store, the determined sets of transmission gears.

15. The computer-readable medium of claim 9, wherein determining the at least one progressive shift limit includes retrieving the at least one progressive shift limit from a look-up table based on the vehicle configuration.

16. The computer-readable medium of claim 9, wherein determining the at least one progressive shift limit includes calculating the at least one progressive shift limit based on performance data associated with components identified in the vehicle configuration.
