Abstract

Disclosed is an auto cruise downhill control (ADC) method for a vehicle. By the method, when the speed of the vehicle exceeds an auto cruise setting speed, the speed of the vehicle is automatically adjusted to be the auto cruise setting speed by using an engine control unit (ECU) and an electronic stability control (ESC) unit. In other words, when a current vehicle speed exceeds a predetermined value compared to a driver's setting speed for auto cruise when the vehicle is operating on a steep decline, automatic braking activation control is performed by the ESC unit to adjust the speed of the vehicle to be the auto cruise setting speed. Additionally, when a driver makes a steep downward adjustment of the setting speed, automatic braking activation control is performed by the ESC unit to decrease the speed of the vehicle to a downwardly adjusted level at an accelerated rate.

Description

technical field [0001] The present invention relates to an auto-cruise downhill control (ADC) method for a vehicle, and more particularly, to an ADC method for a vehicle by which, when the speed of the vehicle deviates from the auto-cruise set speed, The speed of the vehicle can be automatically adjusted to the auto cruise set speed by using the Engine Control Unit (ECU) and Electronic Stability Control (ESC) unit. Background technique [0002] The automatic cruise control system is a constant speed driving device or an automatic speed adjustment device, which can maintain the speed of the vehicle at a constant driving speed by simply activating a switch operation to improve driving convenience by reducing the accelerator pedal operating force. [0003] By using automatic cruise control, the amount of fuel injected into the engine is adjusted based on information on the speed of the vehicle measured by wheel sensors. Thus, the vehicle can be driven according to the speed li...
