The invention discloses a torque control method and system and a vehicle. The torque control method comprises the steps that a crawling torque value is obtained when the vehicle withdraws from the crawling state; and after the vehicle withdraws from the crawling state, a first driving torque value is obtained according to the crawling torque value and the opening degree of an accelerator pedal, so that a motor is controlled to operate through the first driving torque value. The driving torque value is larger than the crawling torque value. The torque control method and system and the vehicle have the following advantages that when the vehicle withdraws from crawling, no sudden change happens on the output torque of a motor system, no impact is generated in a transmission system, prolonging of the service life of the transmission system is facilitated, and the driving and riding comfort is improved at the same time.
