Abstract: System and method for estimating speed of a vehicle is disclosed. Speed of a vehicle is recorded using a first sensor at a time interval of a plurality of time intervals. Further, an acceleration of the vehicle may be recorded using a second sensor at each sub-interval of the time interval. At each sub-interval, a forward speed and a backward speed, of the vehicle are obtained based upon the acceleration at each sub-interval. After obtaining the forward speed and the backward speed, a predefined weight may be assigned to the forward speed and the backward speed at each sub-interval. Subsequently, a corrected speed of the vehicle at each sub-interval is calculated based upon the predefined weight, the forward speed and the backward speed. Further, a slope associated with the speed of the vehicle is determined Based upon the slope, the speed of the vehicle at a sub-interval may be estimated.

Abstract: A method and system for controlling a speed of a vehicle. Acceleration data comprising acceleration samples of the vehicle on a segment of the road is captured. Jerk energy values associated with the vehicle on the segment is computed based upon the acceleration samples. Median jerk energy of the vehicle on the segment may be determined based upon the jerk energy values. Predictive median jerk energy of the vehicle on the segment is computed using a statistical equation. A score associated with the segment is calculated based upon the median jerk energy, the predictive median jerk energy, and a standard deviation (σ). The segment is classified into one of a first set of categories and a second set of categories based upon the score. A feedback signal indicative of controlling the speed of the vehicle is transmitted to a controller based upon the classification.

Abstract: Disclosed are a device, system and methods for detecting an anomaly associated with driving of a vehicle. Z-axis acceleration data is determined at the device. Based on the Z-axis acceleration data, jerk energies are computed and transmitted to the system for analysis. Further, the jerk energies are received for a plurality of trips at the system. Further, at the system, statistical analysis is performed on the jerk energies for determining a hazard rate for each trip of the plurality of trips. Then based on the hazard rate determined for each of the plurality of trips, a trend analysis is performed. Based on the trend analysis, any anomaly associated with the driving of the vehicle is detected. Further, the anomaly detected may be notified to a person associated with the device or with a monitoring terminal.
