Abstract

A system and method for controlling creep torque of a vehicle in which a sensor detects that brakes of the vehicle are being applied and a control portion controls creep torque to be 0 once the vehicle has come to a stop, determines whether the brake is released, and sends a command to an electric motor to generate again the creep torque once the brake is released.

Description

technical field [0001] The present invention relates to a system and method for controlling the creep torque of a vehicle. More particularly, the present invention relates to a system and method for controlling creep torque of a vehicle that reduces noise generated by the creep torque when the vehicle begins to move after a stop. Background technique [0002] Although the braking noise of the vehicle braking system does not directly have a huge impact on the driving performance of the vehicle, it usually plays a certain role in the initial quality satisfaction of the customer buying the car. The importance of marketability and quality differentiation among vehicle manufacturers is magnified in market environments where customer satisfaction is the highest priority, such as the automotive industry. [0003] The creeping squeaking noise of the brake friction assembly is a low frequency noise operating at about 20-200Hz and is a stick-slip phenomenon due to the creeping torque...
