Inference of Vehicular Trajectory Characteristics with Personal Mobile Devices (Patent No.: US 9,228,836)
Patents by Cambridge Mobile Telematics
Cambridge Mobile Telematics accurately measures longitudinal and lateral acceleration using raw three-axis accelerometer data from a smartphone that may be oriented arbitrarily in a moving vehicle or carried by a moving user. Orienting the phone’s three-axis accelerometer to the moving car is applicable to a range of applications, including insurance telematics, driver behavior and risk assessment, and road surface quality assessment.
