Automated collision mitigation system of a vehicle and method thereof

A rear collision mitigation system of a vehicle having a braking system and a drivetrain system, the rear collision mitigation system comprising:

• a vehicle controller operable to determine an impending rear end collision, the vehicle controller determining a free space in front of a host vehicle and operable to accelerate the host vehicle immediately prior to the impending rear end collision and brake the host vehicle immediately after the impending rear end collision;
• a receiving device operable to detect parameters of a remote vehicle located rearwardly of the host vehicle;
• wherein the vehicle controller is configured to and evaluates a stopping distance based on stored data in the host vehicle and determine whether the stopping distance is less than the determined free space in front of the host vehicle;
• wherein the vehicle controller is configured to and evaluates a collision distance of the host vehicle with the remote vehicle based on the detected parameters of the remote vehicle and stored data of the host vehicle;
• wherein the vehicle controller is configured to and evaluates an accelerating time of the host vehicle to reach a collision point and a time-to-collision of the remote vehicle to collide into the host vehicle at the collision point based on the detected parameters of the remote vehicle, the stored data of the host vehicle and the evaluated distances;
• wherein the vehicle controller is configured to and determines to activate the drivetrain system when the vehicle controller indicates that the accelerating time of the host vehicle to reach the collision point is greater than the time-to-collision of the remote vehicle to reach the collision point;
• and
• wherein the vehicle controller is configured to and further determines to activate the braking system when the vehicle controller indicates that the rear end collision has occurred.
