Document Type and Number:
WIPO Patent Application WO/2021/169609
Kind Code:
A1
Abstract:
A torque control method and device for a vehicle, the torque control method comprising: in a process of executing an energy recovery function, determining whether a lifting torque request is received; determining whether an ABS is in an activated state in the situation in which a lifting torque request is not received; if so, reducing the energy recovery torque according to a first torque change gradient; during the period of reducing the energy recovery torque, determining whether the ABS is changed from the activated state to a non-activated state; if so, determining whether the torque required by a first current driver is greater than a first preset value and whether the ABS is in the non-activated state for longer than a first preset period of time; and if so, according to a second torque change gradient, restoring the energy recovery torque to the torque required by the first current driver.
