Abstract:
A remote user can define one or more zone based driver/vehicle behavior definitions. Current vehicle location is analyzed at the vehicle or remotely to determine if the vehicle is approaching or has arrived at a location for which a zone based driver/vehicle behavior has been defined. For zone based driver behavior definitions, a display in the vehicle automatically displays the zone based driver behavior definition to the driver. In some embodiments driver compliance is tracked and non-compliance is reported to the remote user. For zone based vehicle behavior definitions, a vehicle controller at the vehicle responsible for controlling the defined behavior is reprogrammed to impose the defined behavior (no regeneration at location, max speed at location, no idle over 2 minutes at location, etc.). Once the vehicle has left the zone, the controller programming reverts to its prior state, and/or zone based driver behavior definition is no longer displayed.
Abstract:
Disclosed herein are techniques for implementing vehicle ECU reprogramming, so the ECU programming, which plays a large role in vehicle performance characteristics, is tailored to current operational requirements, which may be different than the operational characteristics selected by the manufacturer when initially programming the vehicle ECU (or ECUs) with specific instruction sets, such as fuel maps. In one embodiment, a controller monitors the current operational characteristics of the vehicle, determines the current ECU programming, and determines if a different programming set would better suited to the current operating conditions. In the event that the current programming set should be replaced, the controller implements the ECU reprogramming. In a related embodiment, users are enabled to specify the ECU programming to change, such as changing speed limiter settings.
Abstract:
Data is collected during the operation of a vehicle and used to produce a ranking of a driver's performance, and that ranking is shared on a hosted website, such that the drivers can compare their performance metrics to their peers. Fleet operators can use these performance metrics as incentives, by linking driver pay with performance. Individual fleet operators can host their own website, where driver rankings in that fleet can be compared, or the website can be hosted by a third party, and multiple fleet operators participate. The third party can offset their costs for operating the website by charging participating fleet operators a fee, and/or by advertising revenue. In some embodiments, all driver performance data is displayed in an anonymous format, so that individual drivers cannot be identified unless the driver shares their user ID.

Abstract:
Three dimensional GPS or vehicle position data is used to determine a slope the vehicle is traveling over at a specific point in time. The slope data can then be combined with other metrics to provide an accurate, slope corrected vehicle mass. The vehicle mass can then be used along with other vehicle data to determine an amount of work performed by a vehicle, enabling s detailed efficiency analysis of the vehicle to be performed. To calculate slope, horizontal ground speed (VHGS) can be calculated using the Pythagorean Theorem. One can take the Z/Up magnitude and divide it by the horizontal ground speed. Replacing Z, x and y with directional vectors enables one to calculate slope. The slope data is then used to determine the mass of the vehicle at that time. Pervious techniques to calculate mass did not factor in slope, and thus are not accurate.
