20120191293 | SYSTEM AND METHOD FOR ANALYZING A POWERTRAIN CONFIGURATION - 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. | 07-26-2012 |
20130038438 | SYSTEMS AND METHODS FOR PROVIDING DRIVER SHIFT AIDS - Systems and methods for displaying a driver shift aid are disclosed. In one aspect, an electronic control unit causes a shift indicator to be presented if a need for a shift is detected and vehicle performance after the shift would not be unduly impacted. If the vehicle operator follows the guidance of the shift indicator, vehicle fuel efficiency may be improved while vehicle performance remains adequate. In one aspect, a different indicator may be displayed to prompt the vehicle operator to shift either one gear or two gears. | 02-14-2013 |
20130144581 | SYSTEMS AND METHODS FOR DETERMINING SPEED CONTROL MANAGEMENT SETTINGS - 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. | 06-06-2013 |
20140058654 | SYSTEMS AND METHODS FOR PROVIDING DRIVER SHIFT AIDS - Systems and methods for displaying a driver shift aid are disclosed. In one aspect, an electronic control unit causes a shift indicator to be presented if a need for a shift is detected and vehicle performance after the shift would not be unduly impacted. If the vehicle operator follows the guidance of the shift indicator, vehicle fuel efficiency may be improved while vehicle performance remains adequate. In one aspect, a different indicator may be displayed to prompt the vehicle operator to shift either one gear or two gears. | 02-27-2014 |
20140121933 | FLEXIBLE MAXIMUM VEHICLE SPEED METHOD - In accordance with aspects of the present disclosure, a method of limiting a vehicle speed is provided. The method includes limiting the speed of the vehicle to a predetermined limit under normal operating conditions. The method further includes selectively engaging an override condition in response to an operator generated input. During the override condition, the vehicle can exceed the predetermined limit by a specified offset. The override condition is not available when the vehicle has traveled in the override condition for a predetermined number of miles. | 05-01-2014 |
20140266660 | REAL-TIME DRIVER REWARD DISPLAY SYSTEM AND METHOD - A method and system for improved driver reward display functionality. A driver reward is calculated based on inputs, such as freight fuel, fuel economy, and % idle. The driver reward system configures and displays a primary driver reward image for various menu selections. The primary driver reward image is configured to indicate whether the driver reward is at full penalty, partial penalty, neutral, partial bonus, or full bonus. The image is displayed in one color if above an expected value and another color if below the expected level. Images that indicate to the operator of the vehicle the impact of each input on the overall driver reward or whether each input is improving or worsening may be displayed. A secondary driver reward image may also be displayed to indicate a specific bonus or penalty in miles per hour and speed limit. | 09-18-2014 |
20140277995 | Hierarchical Vehicle De-Rate and Notification System - An on-board vehicle computer system is configured to detect a condition of a vehicle; identify a de-rate cause for the vehicle in a hierarchical set of de-rate causes, wherein the de-rate cause is associated with the condition; select a de-rate type from a set of possible de-rate types based at least in part on the de-rate cause; select an initial de-rate level from a set of possible de-rate levels based at least in part on the de-rate cause; present an operator notification associated with the de-rate cause via an operator interface; activate a de-rate for the vehicle according to the de-rate type and the initial de-rate level; detect a change in the vehicle condition; and update the initial de-rate level based at least in part on the change in the vehicle condition. | 09-18-2014 |
20150278430 | SYSTEMS AND METHODS FOR DETERMINING SPEED CONTROL MANAGEMENT SETTINGS - 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. | 10-01-2015 |
