Systems and methods for transportation mode determination using accelerometer
A method for determining a transportation mode acquires magnetometer and speed data from a mobile device, correlates the magnetometer to the speed data in groupings, and performs spectral analysis on the groups of magnetometer data. Energy calculated for each of a set of frequency components obtained from the spectral analysis is compared to a baseline value to generate a difference, and a transportation mode type is assigned to the vehicle based on the difference.
Vehicle stop support system
Provided is a vehicle stop support system for supporting vehicle stop in an emergency condition. The vehicle stop support system sets a target time period based on physical abnormality of a driver; sets an allowable lateral acceleration, based on the abnormality; estimates a time period required to reach each of a plurality of stop point candidates; estimates a lateral acceleration to be generated during traveling of a vehicle to each of the candidates; sets a stop point; and controls the vehicle to travel to the stop point and stop at the stop point. The system is operable to set, as the stop point, one of the candidates which satisfies a condition that the lateral acceleration estimated with respect thereto is equal to or less than the allowable lateral acceleration, and the required time period estimated with respect thereto is equal to or less than the target time period.

Autonomous driving controller, system including the same, and method thereof
An autonomous driving controller includes: a processor to collect driving data when a vehicle is traveling and calculate a steering override reference value, which is a criterion of determining an override mode, based on the collected driving data; and a storage to store the collected driving data and a set of instructions executed by the processor to calculate the steering override reference value. In particular, the processor controls autonomous driving by varying the steering override reference value based on the collected driving data or information regarding a driver of the vehicle.
