Torque control modeling for torque control of hybrid electric powertrains
An electrified powertrain that generates and transfers drive torque to a driveline of a hybrid electric vehicle is provided. The powertrain includes an engine, an electric motor, a clutch, a torque converter and a controller. The clutch selectively disengages an engine output from a remainder of the electrified powertrain. The torque converter transfers rotating power from at least one of the engine and the electric motor to a transmission. The controller is configured to: receive an impeller speed and a turbine speed of the torque converter; determine a target turbine torque; determine, coefficients as a function of the impeller speed, turbine speed and target turbine torque; update an adaptive lookup table based on the coefficients; and determine an adapted turbine torque based on the updated adaptive lookup table.
PERFECTED BATTERY FOR VEHICLES, KIT AND METHOD FOR THE CONVERSION OF AN ENDOTHERMIC VEHICLE TO A HYBRID VEHICLE
The present invention relates to a perfected battery (1) for vehicles, comprising: a housing (2) bounded by a cover (3) and configured to receive inside: a battery pack (4) configured to store electrical energy and power a motor-alternator (8) of said vehicle, and a service battery (5) in electrical communication with said motor-alternator (8) and configured to: store electrical energy, and power the services of the vehicle, an inverter (6) configured to: put said batteries (5, 6) and said motor-alternator (8) in electrical communication with each other, regulate the delivery of electrical energy from said battery pack (4) to said motor-alternator (8) so that the latter exerts a predefined driving torque on a transmission of the vehicle.
Electrified military vehicle
A control system for operating a military vehicle according to different modes includes processing circuitry that receives a user input indicating a selected mode of the different modes, and operates a driveline and a front end accessory drive (FEAD) of the military vehicle according to the selected mode. The driveline of the military vehicle includes an engine and an integrated motor generator (IMG) and the FEAD includes multiple accessories and an electric motor-generator. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and drives tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.
GEAR-SHIFTING CONTROL METHOD, VEHICLE CONTROLLER, AND HYBRID VEHICLE
A gear-shifting control method, a vehicle controller, and a hybrid vehicle, including: in a gear-shifting speed regulation phase of a gear-shifting process, pre-distributing a total speed regulation intervention torque, which is determined according to a target angular acceleration and a rotational inertia, into an input shaft intervention torque and a clutch intervention torque; and when the input shaft intervention torque does not exceed a torque intervention capability of a first motor, distributing the whole input shaft intervention torque to the first motor. Therefore, the rapid response capability and precision of the motor can be fully utilized to improve the gear-shifting performance.
