A method and a system for a drive control of a vehicle, the method for the drive control of the vehicle includes: obtaining request information reflecting a power demand of a user on the vehicle and performance information reflecting a power performance of the vehicle; determining whether the vehicle meets a condition for activating a parallel operation mode according to the request information and the performance information when a result of comparison between the request information and the performance information indicates that the vehicle power performance cannot meet the power demand of the user on the vehicle; and activating the parallel operation mode of the vehicle in order that the vehicle outputs a power that meets the power demand of the user on the vehicle in the parallel operation mode, when the vehicle meets the condition for activating the parallel operation mode.

An electrically controlled differential gear is disposed between a right front wheel and a left front wheel of a vehicle. The electrically controlled differential gear includes a clutch mechanism that limits a differential operation of the electrically controlled differential gear. A second ECU (control portion) obtains information as to failure associated with actuation of a right front electric brake mechanism. The second ECU obtains a physical amount relating to a required braking force which is applied to the left front wheel and the right front wheel. The second ECU outputs a differential limiting control command for limiting the differential operation of the electrically controlled differential gear to the clutch mechanism (or more specifically, a differential ECU that controls the clutch mechanism) based on the information as to the failure and the physical amount relating to the required braking force.

A series-hybrid vehicle includes an internal combustion engine for electric power generation and a motor generator for travelling. The internal combustion engine is cooled by a second coolant water circuit that has a main radiator. A first coolant water circuit having a sub radiator is used to cool a front wheel-side power train cooling part, a rear wheel-side power train cooling part, a water-cooled condenser, and a low temperature-side intercooler. When the vehicle is accelerating, an electrical compressor for an air conditioner comes to a stop, and the circulation of refrigerant to the water-cooled condenser is brought to a halt.
