Abstract

A fault determination system of a button-type shifter is provided. The system maximally guarantees the operation of a shift button while determining a failure of the shift button and improves reliability and fault diagnosis performance for the shift button. The system includes a base that is installed within a vehicle and includes shift buttons and contact points for each of the shift buttons. A controller receives contact signals from the contact points to thus determine a failure of the shift button when any one of the contact points is not sensed or is stuck when the shift button is engaged.

Description

technical field [0001] The present invention relates to a fault determination system of a push-button shifter, which improves reliability and fault diagnosis performance in determining whether a shift button is operable and prevents errors in driving a vehicle by maximally securing the operation of the shift button. Background technique [0002] Generally, since power for driving a vehicle changes based on whether the vehicle is loaded, road conditions, or running speed, a transmission for changing torque is usually installed between an engine and driving wheels. The transmission appropriately changes driving power based on running conditions, and includes gears for vehicle reverse. [0003] In recent years, automatic transmissions are increasingly used, in which gear shifting is performed automatically rather than manually by a driver, and an optimal gear position is selected based on a set driving speed and an engagement degree of an accelerator pedal. This automatic tran...
