Systems and methods for improving fuel economy in vehicles such as Class 8 trucks are provided. In some embodiments, signals indicating states of the powertrain are collected and used to generate fuel rate optimization values. Fuel rate optimization values may indicate a difference between optimum fuel flow rates and actual fuel flow rates during a vehicle drive cycle. Recorded fuel rate optimization values may be used to compare different vehicle configurations during testing, and may also be used to evaluate vehicle performance during real-world operation.

A vehicle service system and method to determine spatial parameters of a vehicle, employing a display system under processor control, to display or project visible indicia onto surfaces in proximity to a vehicle undergoing a safety system service or inspection identifying one or more locations, relative to the determined vehicle centerline or thrust line, at which a calibration fixture, optical target, or simulated test drive imagery is visible for observation by a sensor onboard the vehicle.

A test apparatus is provided for testing a sensorless check device of an actuator. The sensorless check device is arranged to be used by mechanically moving a check device pin from a resting position to an actuation position and then releasing the check device pin to allow it to return to a resting position urged by an elastic return mechanism. The test apparatus comprises: a piston for contact with an actuator surface associated with the check device pin; a piston spring for urging the piston toward the actuator surface, wherein the piston spring is softer than the elastic return mechanism of the check device; and an adjustment and testing mechanism.

A system, method, and computer-readable medium for facilitating treatment of a vehicle damaged in a crash utilizes near real-time monitoring of the market value of a vehicle type that includes the damaged vehicle, its vehicle parts, and/or one or more arranged vehicle treatments to approximate an extent of damage to the damaged vehicle and determine a prospective vehicle treatment facility for treating the damaged vehicle. In particular, the system continually monitors the market value of a vehicle, its vehicle parts, and/or a prescribed vehicle treatment to calculate a treatment complexity level, e.g., vehicle repair, total loss; for treating the damaged vehicle.

Embodiments of the present invention relate to the field of automobile technologies, and disclose a vehicle detection method, apparatus and a vehicle diagnostic device. The vehicle detection method includes: acquiring at least two vehicle identification numbers of a vehicle; comparing the at least two vehicle identification numbers to obtain a comparison result; and generating a detection result according to the comparison result, and outputting the detection result. Through comparison of a plurality of the vehicle identification numbers, consistency of the vehicle identification numbers is detected. Therefore, a user may be helped to determine whether a vehicle is overhauled or a part thereof is replaced.

A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.
