Classification: CPC B  Y | IPC B

Claim 19:
20. A vehicle control system comprising:
a processor;
a memory storing one or more instructions, which when executed cause the processor to:
determine whether defined conditions for controlling creep torque of a vehicle are met, where whether the defined conditions for controlling creep torque are met is determined by:
determining whether a vehicle acceleration is lower than a threshold acceleration;
determining whether a vehicle speed is lower than a threshold speed;
determining whether a brake of the vehicle is engaged; and
determining whether an accelerator is engaged;

wherein
if the brake is determined to be engaged, then determining that the defined conditions are not met;
if the accelerator is determined to be engaged, then determining that the defined conditions are not met;
if the vehicle acceleration is determined to be above the threshold acceleration, then determining that the defined conditions are not met; and
if the vehicle speed is determined to be greater than the threshold speed, then determining that the defined conditions are not met; and
in response to the defined conditions being met, produce a control signal
to increase an input torque, and
to cause the vehicle to reach a target creep-generated-vehicle-speed,
wherein after the defined conditions for controlling the creep torque are met, an acceleration that is applied is selectable by applying the brake at a selected acceleration, wherein after the applying the brake to select the acceleration, the input torque is set to produce the selected acceleration when the brake is no longer being applied.
