Abstract

A torque control method and apparatus for a vehicle, including: determining whether a torque change request is received, during a process of performing an energy recovery function; determining whether an antilock brake system is in an active state, in case that the torque change request is not received; if so, decreasing an energy recovery torque with a first torque change gradient; determining whether the antilock brake system is transited from the activated state to a non-activated state, during a process of decreasing the energy recovery torque; if so, determining whether it is satisfied that a first current driver demand torque is greater than a first preset value and the antilock brake system is in the non-activated state for longer than a first preset time; and if satisfied, recovering the energy recovery torque to the first current driver demand torque with a second torque change gradient.
