摘要

#CMT# #/CMT# The method involves activating a brake pedal (20) such that an electrical machine (8) applies the electrical braking torque to wheels (2), and detecting reduction of the electrical breaking torque by a traction chain calculator (12). The value of the electrical braking torque reduction is informed to a hydraulic breaking calculator (21), and a hydraulic braking system (15) is controlled by the hydraulic braking calculator such that the electrical braking torque applied to the wheels by a brake (17) compensates the electrical braking torque reduction. #CMT#USE : #/CMT# Method for breaking of a hybrid vehicle. Can also be used for electrical vehicles. #CMT#ADVANTAGE : #/CMT# The method compensates the electrical braking torque reduction by the electrical braking torque applied to the wheels, so that the intrinsic variations of the power provided by the electric chains is known by the driver based on the demand of braking and regulation, thus preserving the coherent braking with the request of the driver. The braking speed is high, thus ensuring the safety of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a hybrid vehicle implementing the braking method. 2 : Wheels 8 : Electrical machine 12 : Traction chain calculator 15 : Hydraulic braking system 17 : Brake 20 : Brake pedal 21 : Hydraulic braking calculator.
