Braking control system with object detection system interaction

The braking control system includes a control unit configured to be electronically connected to at least an object detector and a host vehicle speed sensor for automatically controlling, depending on a host vehicle speed (Vm) and a relative distance (L), a braking force needed for an automatic braking operation, comprising preliminary braking control or supplementary braking control, without driver's braking action when the host vehicle is approaching an object ahead, such as a preceding vehicle. The control unit detects the presence or absence of a driver's intention for lane-changing. In the presence of the driver's intention for lane-changing, the control unit inhibits preliminary braking control, initiated prior to the driver's braking action, or reduces the degree of limitation on supplementary braking control, through which a value of a controlled quantity is brought closer to a target deceleration rate needed for collision-avoidance.
