A vehicle torque distribution method includes: determining a uniform-speed torque distribution coefficient according to a speed parameter of the vehicle, and a preset corresponding relationship between the speed parameter and the uniform-speed torque distribution coefficient; determining an acceleration torque distribution coefficient according to the speed parameter of the vehicle, and a preset corresponding relationship between the speed parameter and the acceleration torque distribution coefficient; determining a first weight coefficient of the uniform-speed torque distribution coefficient and a second weight coefficient of the acceleration torque distribution coefficient according to an acceleration of the vehicle and a weight coefficient corresponding relationship; and obtaining a target torque distribution coefficient by performing a weight processing on the uniform-speed torque distribution coefficient and the acceleration torque distribution coefficient according to the first weight coefficient and the second weight coefficient.

In a drive apparatus for a vehicle, a first HEV mode and an all-wheel drive mode can be established. In the first HEV mode, the vehicle is caused to run in front- or rear-wheel drive, by causing a first electric motor to be operated as a generator, while causing a third electric motor to be operated as a prime mover to transmit a torque to a second drive shaft. In the all-wheel drive mode, the vehicle is caused to run in all-wheel drive, by causing an electric power to be transferred between the first and second electric motors, while causing the third electric motor to be operated as the prime mover to transmit the torque to the first and second drive shafts, and the first, second and third electric motors are controlled such that a torque distribution between the first and second drive shafts becomes a required ratio.

A method for controlling a starting process of a vehicle includes activating a control sequence and setting a control sequence signal, defining a maximum engine drive torque, and detecting a drive request for a starting process. The method further includes, in response to the drive request, controlling a clutch-gearbox unit with an engagement process duration, controlling wheel slip of driven wheels by determining wheel speeds of the driven wheels and at least setting an output drive torque at the output shaft, and redefining the maximum engine drive torque depending on the wheel slip and a driving speed. The method also includes deactivating the control sequence and resetting the control sequence signal when limit values are reached.
