ANTI-COLLISION LONGITUDINAL SELF-ADAPTIVE ADJUSTING SYSTEM AND METHOD THEREOF

An anti-collision longitudinal self-adaptive adjusting system includes a host vehicle, an external environment sensing module, a cabin internal status sensing module and a controller. A self-adaptive deceleration command calculating unit calculates a self-adaptive deceleration command at least according to a maximum deceleration threshold, a seatbelt dataset and a passenger standing dataset and calculates a suspension damper command according to the self-adaptive deceleration command. A self-adaptive deceleration command output unit calculates a braking point distance at least according to a system operating delay time and the self-adaptive deceleration command so as to obtain a brake start-till-stop time. If the brake start-till-stop time is larger than or equal to the obstacle collision time, the self-adaptive deceleration command is output to the propulsion module and the braking module for adjusting the longitudinal velocity, and the suspension damper command is output to the suspension module for adjusting the suspension damper.
