Method for control regenerative braking of electric vehicle

Abstract

A method for controlling regenerative braking of a vehicle includes initiating the regenerative braking, detecting an amount of slip of a wheel during the regenerative braking, if the amount of slip is increasing, reducing a regenerative braking torque, and if the amount of slip is greater than a set value, actuating an antilock brake system and reducing the regenerative braking torque or a hydraulic braking torque continuously until the vehicle is stopped. Alternatively, if the amount of slip is increasing, the regenerative braking torque is not reduced.

1 . A method for controlling regenerative braking of a vehicle, comprising:
 initiating the regenerative braking;   detecting an amount of slip of a wheel during the regenerative braking;   if the amount of slip is increasing, reducing a regenerative braking torque; and   if the amount of slip is greater than a set value, actuating an antilock brake system and reducing the regenerative braking torque continuously until the vehicle is stopped.   
   
   
       2 . The method of  claim 1 , wherein a hydraulic torque is used if the regenerative braking torque is insufficient. 
   
   
       3 . The method of  claim 2 , wherein the hydraulic braking torque is reduced if a needed reducing amount of braking torque is larger than a reducing amount of the regenerative braking torque. 
   
   
       4 . A method for controlling regenerative braking of a vehicle, comprising:
 initiating the regenerative braking;   detecting an amount of slip of a wheel during the regenerative braking;   if the amount of slip is increasing, not reducing a regenerative braking torque; and   if the amount of slip is greater than a set value, actuating an antilock brake system and reducing the regenerative braking torque continuously until the vehicle is stopped.   
   
   
       5 . A method for controlling regenerative braking of a vehicle, comprising:
 initiating the regenerative braking;   detecting an amount of slip of a wheel during the regenerative braking;   if the amount of slip is increasing, not reducing a regenerative braking torque; and   if the amount of slip is greater than a set value, actuating an antilock brake system and reducing a hydraulic braking torque continuously until the vehicle is stopped.   
   
   
       6 . The method of  claim 5 , wherein the regenerative braking torque is reduced if a needed reducing amount of braking torque is larger than a reducing amount of the hydraulic braking torque.
