Control system and method for stopping vehicle

摘要

Provided are a control system and method for stopping a vehicle, which reduce jerk when a vehicle controlled by an SCC system is stopped by the SCC system without a driver's manipulation. A desired target stop distance between a controlled vehicle and a front vehicle is set. Proposed is a formula for calculating a target acceleration in which a jerk is not caused when the target stop distance is maintained and then the controlled vehicle stops. By controlling the stop of the controlled vehicle according to the acceleration that has been calculated with the formula, the controlled vehicle is stopped without the occurrence of a jerk.

主权项

1. A smart cruise control (SCC) system, comprising:
a receiver configured to receive distance information and speed information of an ambient vehicle and speed information and acceleration information of a control vehicle that are sensed by a sensor of the control vehicle; a stop control activator configured to generate a stop control activation signal when a front vehicle is determined to be in a stop state while the control vehicle is driving, on the basis of at least one of a plurality of the received information; and a controller configured to set one of a plurality of predetermined stop distance candidates as a target stop distance when the stop control activation signal is received, to check whether there is a design variable range that enables soft-stop over the set target stop distance on the basis of the information received by the receiver, and to calculate a target acceleration by using the target stop distance and a design variable determined according to the checked result.
