20090247354 | METHOD FOR CONTROLLING AN ELECTROMAGNETIC RETARDER - A method for controlling an electromagnetic retarder comprising a current generator into which an excitation current is injected. The method consists in determining a maximum allowable intensity (Im) of the excitation current to be injected into the stator primary coils of the retarder which includes a shaft bearing secondary windings and field coils which are supplied by the secondary windings, said primary coils and secondary windings forming the generator. The retarder includes a jacket inside which the field coils generate Foucault currents and a circuit for the liquid cooling of said jacket. More specifically, the method consists in determining the maximum allowable intensity in real time, such as to reach a critical temperature of the cylindrical jacket and determining said critical temperature taking account of a temperature value of the coolant. The method is suitable for retarders that are intended for vehicles such as heavy vehicles. | 10-01-2009 |

20130178332 | CONTROL APPARATUS FOR PREVENTING ROLLING BACK OF AN ELECTRICALLY DRIVEN VEHICLE UPON START-UP THEREOF - In an electrically driven vehicle propelled by an electric machine (motor)equipped with a collaborative braking system of regenerative and frictional braking capacities, in order to achieve the “rollback prevention” at starting on an sloping road, when the regenerative braking is not available due to charging restriction to battery, frictional braking is used instead of regenerative braking and wheels are (automatically, i.e. not manually by driver) braked with friction to prevent the rollback. Moreover, in addition to braking wheels by frictional braking, further control is performed to adjust and match the magnitude of frictional braking force to a braking force in accordance with the starting operation. Thus, at the time of rollback prevention by the frictional braking as well, the similar prevention of rollback will be possible as the prevention by way of regenerative braking such that the effect of rollback prevention may be achieved without a feel of discomfort. | 07-11-2013 |

20130288855 | SYSTEM AND METHOD FOR CONTROLLING VEHICLE CREEP TORQUE - A system and method for controlling creep torque in a vehicle with an electric powertrain, like a hybrid electric vehicle (HEV). The method uses a combination of driver braking intent and other vehicle conditions, such as vehicle speed, to determine when creep torque is not needed and to reduce and/or cancel it accordingly. By reducing and/or cancelling the creep torque during periods where energy is being unnecessarily expended by the electric powertrain in order to work against the brakes, the present method is able to improve the overall efficiency of the vehicle. | 10-31-2013 |
