Patent ID: 8311692

Claim:
Braking method for a vehicle having wheels, in particular a hybrid vehicle, said vehicle comprising: a drive system comprising a heat engine, an electric machine, and an automatic gearbox with torque interrupt, wherein the automatic gearbox is connected (i) to the electric machine and (ii) to the vehicle wheels, a drive system computer, said drive system being controlled by the drive system computer, a hydraulic braking system, said hydraulic braking system applying a hydraulic braking torque to the vehicle wheels by means of brakes when said hydraulic braking system is actuated, a brake computer, said hydraulic braking system being controlled by the brake computer, and a brake pedal, said brake pedal producing a braking torque applied to the vehicle wheels when said brake pedal is actuated, wherein the method comprises: actuating the brake pedal, wherein the electric machine applies an electric braking torque to the wheels, when a gear change is anticipated by the gearbox, transmitting information from the gearbox to the drive system computer that a gear change is anticipated, then, transmitting information from the drive system computer to the brake computer that an electric braking torque will be canceled during the gear change, wherein the gear change starts at a gear change starting time and the transmitting of the information that the electric braking torque will be canceled during the gear change is performed at a first information transmission time earlier than the gear change starting time, controlling the hydraulic braking system by the brake computer, wherein the hydraulic braking system offsets the electric braking torque canceled during the gear change, and offsetting the electric braking torque by the hydraulic braking torque in a progressive manner over a first time period between the first information transmission time and the gear change starting time.
