ENERGY MANAGEMENT FOR HYBRID ELECTRIC VEHICLE DURING TRAILER SWAY
First Claim
1. A system for stabilizing a hybrid electric vehicle having a plurality of wheels and towing a trailer, the system comprising:
- a regenerative braking system for braking at least one wheel of the hybrid electric vehicle;
a non-regenerative braking system for braking at least one wheel of the hybrid electric vehicle; and
a stabilization system coupled to the regenerative braking system and the non-regenerative braking system, the stabilization system determines a direction of rotation and a speed of the hybrid electric vehicle, compares the speed of the hybrid electric vehicle to a predetermined low speed threshold value and a predetermined high speed threshold value, instructs the regenerative braking system to brake at least one wheel included in the hybrid electric vehicle when the speed is less than or equal to the predetermined low speed threshold value, and instructs the regenerative braking system to brake at least one wheel included on a side of the hybrid electric vehicle opposite the direction of rotation and at least one of regenerative braking system and the non-regenerative braking system to provide an extra stabilizing braking torque to at least one wheel included on a side of the hybrid electric vehicle opposite the direction of rotation when the speed is greater than the predetermined high speed threshold value.

Abstract
Systems and methods for stabilizing a hybrid electric vehicle (“HEV”) towing a trailer. One system includes a regenerative braking system, a non-regenerative braking system, and a stabilization system. The stabilization system determines a direction of rotation and a speed of the HEV and compares the HEV'"'"'s speed to a predetermined low speed threshold value and a predetermined high speed threshold value. The stabilization system instructs the regenerative braking system to brake at least one wheel when the speed is less than or equal to the predetermined low speed threshold value and instructs the regenerative braking system to brake at least one wheel opposite the direction of rotation and at least one of the regenerative braking system and the non-regenerative braking system to provide an extra stabilizing braking torque to at least one wheel opposite the direction of rotation when the speed is greater than the predetermined high speed threshold value.
