Abstract: In a torque control method of a drive system of an electric vehicle, in which torque is generated while evading a backlash band to prevent occurrence of backlash in the drive system, a front wheel torque command is determined as a value of equal to or less than a maximum front wheel torque threshold set to a negative (−) torque value, a rear wheel torque command is determined as a value of equal to or greater than a minimum rear wheel torque threshold set to a positive (+) torque value, and when an absolute value of the maximum front wheel torque threshold, and the minimum rear wheel torque threshold are referred to as offset torques, the offset torques are values varied depending on drive system state information.

Abstract: In a method and system for determining a DTE of a vehicle, real-time transportation situation information from a current position of the vehicle to a destination is transmitted to a vehicle. The transmitted transportation situation information and obtaining vehicle forward driving situation information to the destination are received. Predicted battery consumption energy consumed for traveling from the current position to the destination using a battery usage prediction model to which the obtained vehicle forward driving situation information and current vehicle state information obtained from the vehicle are input are predicted and determined. A DTE at the destination as a predicted value at the current position is determined using the determined predicted battery consumption energy to the destination.

Abstract: A method for determining deterioration of a dry clutch mounted between an engine and a motor of a hybrid vehicle includes determining whether an entry condition to determine the deterioration of the dry clutch is satisfied. Roughness of the dry clutch is determined when the entry condition is satisfied. A deviation between the roughness of the dry clutch and a reference value is calculated, and the deviation is compared with a threshold value. A roughness counter of the dry clutch is increased when the deviation is larger than the threshold value. The roughness counter of the dry clutch is compared with a boundary value. It is determined that the dry clutch deteriorates when the roughness counter of the dry clutch is larger than the boundary value.
