VEHICLE CONTROLLING APPARATUS
A vehicle controlling apparatus includes an engine processor, an electric motor, an electric power storage, an SOC detector, an internal resistance detector, and a resistance threshold setting unit. The engine processor is configured to stop an engine of a vehicle on the basis of a stop condition, and start the engine on the basis of a start condition. The engine processor is configured to prohibit a stop of the engine based on the stop condition based on determining that an internal resistance of the electric power storage detected by the internal resistance detector is equal to or greater than a resistance threshold set by the resistance threshold setting unit on the basis of a state of charge of the electric power storage, and permit the stop of the engine based on determining that the internal resistance is less than the resistance threshold.
Systems and methods for operating a torque converter clutch
Systems and methods for improving operation of a hybrid vehicle driveline are presented. In one example, a margin torque for closing a torque converter clutch is adjusted responsive to a state of engine operation.
MOTIVE POWER SYSTEM, TRANSPORTATION APPARATUS, AND ELECTRIC POWER TRANSMISSION METHOD
A motive power system includes a first energy storage, a second energy storage, an actuator, an internal combustion engine, an electric generator, a power transmission circuit, and circuitry. The circuitry is configured to control the power transmission circuit to charge at least the second energy storage via the electric generator. The circuitry is configured to control the power transmission circuit to charge the first energy storage with electric power supplied from the second energy storage when a first charge rate of the first energy storage is lower than a first threshold.
SHIFT CONTROL APPARATUS AND METHOD OF VEHICLE
The present disclosure relates to a shift control apparatus of a vehicle and its method. In particular, the shift control apparatus includes: a transmission including a first clutch and a second clutch; a torque source to generate power for driving a vehicle; a data detector to detect a vehicle state data; and a vehicle controller to connect a current stage synchronizer to a next stage driving gear if the vehicle state data satisfy a shift condition, release the first clutch to be connected to the driving gear of a current stage, perform a speed control of a torque source while maintaining the second clutch connected to the driving gear of the next stage in a slip state, and release the second clutch and connect the first clutch if the vehicle stage data satisfy a speed control completion condition to complete a shift to a target stage.
Permanent Magnet Electric Machine
An interior permanent magnet electric machine includes a stator having a plurality of teeth disposed around a circumference oriented radially towards a center defining slots interposed between each of the teeth, and a conductive winding wrapped around each of the teeth of the stator to receive an electrical current. The electric machine also includes a rotor which is rotatable relative to the stator. The rotor defines a plurality of openings to receive permanent magnets near an outer portion of the rotor and a number of spokes interposed between mass reduction cutouts located closer to the center relative to the permanent magnets. Each of the permanent magnets defines a magnetic pole and each of the spokes is circumferentially aligned with one of the magnetic poles.
CONTROL METHOD OF POWER TRAIN FOR HYBRID VEHICLE AND CONTROL SYSTEM FOR THE SAME
A control method of a power train for a hybrid vehicle is provided. The method includes determining whether an engine corresponds to an optimal operating point when intervention for upshifting is demanded during an HEV driving mode and determining whether an amount of demanded intervention is equal to or less than a value adding maximum intervention torques of a drive motor and an HSG. Each intervention torque of the drive motor and the HSG is determined to adjust a whole energy-collect rate by the drive motor and the HSG to a maximum value of the amount of demanded intervention, and simultaneously, the value adding the intervention torques of the drive motor and the HSG satisfies the amount of demanded intervention.
MOTIVE POWER SYSTEM, TRANSPORTATION APPARATUS, AND ELECTRIC POWER TRANSMISSION METHOD
A motive power system includes a first energy storage, a second energy storage, an actuator, an internal combustion engine, an electric generator, a power transmission circuit, and circuitry. The circuitry is configured to control the power transmission circuit to charge at least the second energy storage via the electric generator. The circuitry is configured to control the power transmission circuit such that only the first energy storage supplies electric power to the actuator for a predetermined period when a charge rate of the second energy storage is lower than a first threshold.
APPARATUS AND METHOD FOR CONTROLLING CHARGE OF HYBRID ELECTRIC VEHICLE
A charge control apparatus of a hybrid vehicle is provided. The apparatus adjusts charge of a hybrid vehicle based on a vehicle running state when entering a charge mode. The charge control apparatus includes an engine clutch that is disposed between an engine and a first motor to selectively connect the engine and the first motor and a battery that provides a voltage to the first motor. A data detection unit detects driving data for charging the battery and a vehicle controller generates an average speed for a predetermined time using a vehicle speed of the driving data. In addition, the controller sets a charge mode based on the average speed and charges the battery using the charge mode.

A transmission (G) includes an input shaft (GW1), an output shaft (GW2), an electric machine (EM), a plurality of planetary gear sets (P1-P3; 2P1-2P5), and gear-implementing shift elements (S1-S6; 2S1-2S5). Via engagement of a first of the gear-implementing shift elements (S1, 2S1), which is a force-locking shift element having a variable torque transmission capacity, the input shaft (GW1) and an element (E1, 22E1) of one of the planetary gear sets (P3; 2P4) can be brought into a fixed rotational speed relationship with respect to each other. Another element (E2, 22E2a, 22E2b) of one of the planetary gear sets (P1, 2P3, 2P5) is permanently connected to a rotor (R) of the electric machine (EM). By engaging an auxiliary shift element (ZS, 2ZSa, 2ZSb), which is a form-locking shift element, the rotor (R) and the input shaft (GW1) can be brought into a fixed rotational speed relationship with respect to each other.
Method and control unit for operating a motor vehicle drive train
A method for operating a drive train of a motor vehicle may include, for a starting process of an internal combustion engine, transferring the separating clutch from a disengaged condition into an engaged condition or a slip state such that the electric machine accelerates the internal combustion engine to a starting speed. The method may further include actuating a torque-transmitting element between the electric machine and the output shaft to enter a slip state. The method may also include increasing the torque of the electric machine to reliably reach and hold the slip state of the torque-transmitting element. Additionally, the method may include operating the electric machine as a generator or as a motor depending on an expected load direction of the drive train during the starting process to reliably reach and hold the torque-transmitting element in the slip state.
