Abstract
A method for determining a driving state of a vehicle includes determining a torque command of a vehicle drive apparatus based on vehicle driving information collected during driving of the vehicle, determining an acceleration error defined as a difference between a reference longitudinal acceleration of the vehicle interlocked with the torque command and a measured longitudinal acceleration of the vehicle, determining an acceleration disturbance rate defined as a difference between an actual rotational acceleration of the vehicle drive and a reference drive apparatus rotational acceleration interlocked with the torque command based on the determined torque command, integrating the determined acceleration disturbance rate to determine the acceleration disturbance, and determining a current vehicle driving state of the vehicle based on the determined acceleration error, the determined acceleration disturbance rate and the acceleration disturbance.
