CONTROL APPARATUS AND CONTROL METHOD FOR ADAPTIVE CRUISE CONTROL OF VEHICLE

The present disclosure provides an adaptive cruise control (ACC) device and method for a vehicle. The ACC method includes: enabling an ACC function based on an operating signal of a driver, and after the ACC function is enabled, setting, by the driver, a cruising velocity in an ACC mode; determining, by an ACC module, whether there is another vehicle in front of a current vehicle; and if there is no vehicle in front of the current vehicle, enabling the current vehicle to travel at the cruising velocity set by the driver; or if there is another vehicle in front of the current vehicle, enabling, by the ACC module, a variable time gap calculation model to calculate a time headway between the current vehicle and the front vehicle in real time, and adjusting, by the ACC module, the cruising velocity of the current vehicle based on the time headway calculated in real time; and when the current vehicle is cornering in the ACC mode, adjusting, by the ACC module, the cruising velocity of the current vehicle based on a cornering strategy. The present disclosure utilizes the variable time gap calculation model to calculate the time headway in real time and allows a prompt response to acceleration and deceleration of the front vehicle, thereby greatly shortening response time of the driver. An ACC system in the present disclosure has rich functions and can meet diverse needs of users.
