Abstract: A method includes receiving operational data from a plurality of vehicles comprising a fleet of vehicles operating in an area of interest, the operational data indicating a motion and a corresponding location of the vehicle; processing the received operational data to identify events of interest, wherein each of the identified events of interest has an event type and has associated therewith a geographic area in which the event of interest occurred; and identifying clusters of the events of interest, wherein each of the clusters comprises multiple occurrences of ones of the events of interest having the same type and having associated therewith the same geographic area. A responsive action to mitigate operating conditions associated with the event type of the events of interest of the at least one of the identified clusters may subsequently be taken.

Abstract: A technique controls an electric brake of a vehicle. The technique involves continuously providing power to the electric brake of the vehicle to continuously disengage the electric brake and allow the vehicle to move. The technique further involves, while power is continuously provided to the electric brake and the vehicle is moving, sensing a fault condition. The technique further involves, in response to sensing the fault condition, providing electric pulses to the electric brake in place of continuously providing power to the electric brake, the electric pulses having varying pulse timing that controls braking of the vehicle. Accordingly, the vehicle is able to provide a more consistent braking response regardless of variations in certain factors such as brake calibration and/or current wear, the current weight in the vehicle, the current temperature, etc.

Abstract: A technique controls regenerative braking to reduce skidding of a vehicle. Such a technique involves imparting rotation to an alternating current (AC) electric motor to move the vehicle to a first commanded vehicle speed; applying a regenerative braking power to the AC electric motor to bring the vehicle to a second commanded vehicle speed; while applying the regenerative braking power, adjusting the level of regenerative braking power applied to follow a predetermined speed reduction rate; while adjusting the level of regenerative braking power applied, provide a limit to the maximum level of regenerative braking power available; and while providing the limit to the maximum level of regenerative braking power available, adjusting the limit to the maximum level of regenerative braking power available based on a current speed of the vehicle.

Abstract: A technique is performed on a vehicle having a lithium battery and a temperature control apparatus. The technique involves receiving a temperature reading from temperature sensing circuitry. The technique further involves performing a comparison operation that compares the temperature reading from the temperature sensing circuitry to a target temperature range. The technique further involves, in response to a result of the comparison operation indicating that the temperature reading is outside the target temperature range, automatically providing electric power from an external battery charger to the temperature control apparatus of the vehicle. The external battery charger is distinct and separate from the vehicle. Additionally, the temperature control apparatus adjusts the temperature of the lithium battery of the vehicle in response to the electric power automatically provided from the external battery charger (e.g., heating or cooling the lithium battery to improve battery capacity and preserve battery life).

Abstract: A prime mover for a lightweight vehicle comprising an internal combustion engine, a starter motor integrally integrated with the internal combustion engine, and a housing for the prime mover. The prime mover additionally comprises a Hall Effect sensor and an prime mover control module structured and operable to communicate with the Hall Effect sensor, determine when operation of the internal combustion engine should cease, and upon the determination that operation of the internal combustion engine should cease, utilize the communication from the Hall Effect sensor to stop the internal combustion engine such that a piston of the internal combustion engine is positioned at between 15° and 25° after bottom-dead-center.

Abstract: A technique provides power-limiting regenerative braking to a utility vehicle. The technique involves detecting that the utility vehicle is moving in a forward direction at a first speed. The technique further involves applying a first regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the first speed. The technique further involves detecting that the utility vehicle is moving in the forward direction at a second speed which is less than the first speed. The technique further involves applying a second regenerative braking power level to the utility vehicle in response to detecting that the utility vehicle is moving in the forward direction at the second speed. The second regenerative braking power level is lower than the first regenerative braking power level.
