Anti-collision longitudinal self-adaptive adjusting system and method thereof

An anti-collision longitudinal self-adaptive adjusting system, comprising:

• a host vehicle, comprising:
• a plurality of wheels;
• a propulsion module configured to provide a power to the wheels;
• a braking module configured to provide a braking force to the wheels and to obtain a longitudinal velocity and a road surface friction coefficient as the host vehicle moves on a road;
• and
• a suspension module connected to the wheels and configured to obtain a suspension damper as the host vehicle moves on the road;
• an external environment sensing module disposed at the host vehicle, the external environment sensing module configured to detect at least one obstacle;
• a cabin internal status sensing module disposed at the host vehicle and comprising:
• a seatbelt detecting unit configured to detect whether at least a sitting member of a plurality of passengers on the host vehicle is present so as to obtain a seatbelt dataset;
• and
• a passenger standing detecting unit configured to detect whether at least a standing member of the passengers is present so as to obtain a passenger standing dataset;
• and
• a controller electrically connected to the suspension module, the propulsion module, the braking module, the external environment sensing module and the cabin internal status sensing module, the controller comprising:
• a collision risk estimating unit configured to calculate an obstacle collision time according to the at least one obstacle detected by the external environment sensing module;
• a maximum deceleration threshold calculating unit configured to calculate a maximum deceleration threshold according to a maximum braking deceleration of the braking module and a maximum road deceleration corresponding to the road surface friction coefficient;
• a self-adaptive deceleration command calculating unit configured to calculate a self-adaptive deceleration command at least according to the maximum deceleration threshold, the seatbelt dataset and the passenger standing dataset and to calculate a suspension damper command according to the self-adaptive deceleration command;
• and
• a self-adaptive deceleration command output unit configured to calculate 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, wherein 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.
