A control method for a motor-driven vehicle is provided. The method includes calculating a correction torque of a drive motor through a difference between speeds of wheels or a variance rate of the difference between speeds of the wheels and comparing a calculated correction torque with a current required torque of the drive motor. When the calculated correction torque is greater than the current required torque, the drive motor is operated based on the current required torque. When the calculated correction torque is less than or equal to the current required torque, the drive motor is operated based on the calculated correction torque, or the required torque of the drive motor is corrected to correspond to the calculated correction torque and the drive motor is operated based on a corrected required torque of the drive motor.

A power control system may include at least one of batteries, a motor, and a data logic analyzer that can interpret certain variable conditions of a transport, such as a tractor trailer, moving along a road or highway. The data can be used to determine when to apply supplemental power to the wheels of a trailer to reduce fuel usage. One example device may include at least one of: a power creation module that generates electrical power, a battery which store the electrical power, a motor affixed to a trailer axle of a trailer which provides a turning force to the trailer axle when enabled to operate from the stored electrical power of the battery, and a motor controller configured to initiate the motor to operate according to a predefined sensor condition.

Systems of an electrical vehicle and the operations thereof are provided that use identifiers and sensed power source parameters to determine whether a rule, such as a warranty or licensing requirement, has been violated.

A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.

A vehicle includes a step-ratio automatic transmission having clutches engageable to provide forward and reverse gears, an electric machine selectively coupled to the transmission, a main pump powered by the electric machine and supplying oil to actuate selected transmission clutches, a gear selector configured for selecting a transmission gear, and a controller configured to stop the electric machine when the gear selector selects park or neutral, to operate the electric machine in a speed control mode using a higher controller gain in response to the gear selector selecting forward or reverse while the electric machine is stopped until the electric machine and the main pump reach a first speed threshold to reduce engagement delay of at least one of the transmission clutches, and to operate the electric machine using a lower controller gain when the electric machine and the main pump exceed the first speed threshold.

A device includes a microprocessor and a computer readable medium coupled to the microprocessor. The computer readable medium includes instructions stored thereon that cause the microprocessor to receive output from at least one sensor monitoring an interior space of a vehicle and determine, based on the received output, a condition of an occupant in the interior space of the vehicle. The instructions cause the microprocessor to determine, based on the determined condition of the occupant, to alter a first presentation of information displayed to a display device of the vehicle to a second presentation of the information displayed to the display device. The instructions case the microprocessor to render the second presentation of the information to the display device of the vehicle to replace the first presentation of the information displayed to the display device of the vehicle.

A method of controlling a mode transition of a hybrid vehicle includes determining whether a mode transition from a first mode to a second mode is required based on a first torque, the first torque being a current required torque. A second torque, which is a required torque expected to be generated at a near-future time from a current time, is also determined. A predicted gear shift time point and a predicted engagement time point of an engine clutch are determined based on the second torque. The mode transition to the second mode is performed when it is determined that the mode transition to the second mode is required and the predicted engagement time point is earlier than the predicted gear shift time point.

An off-board load power management system for an electrified vehicle is provided. The system may include a DC-to-AC inverter for providing power to auxiliary loads. Using a manual selector, an operator may select an amount of power to be allocated for inverter use at all time during vehicle operation. A controller may guarantee the selected amount of power is available for inverter use and control a generator accordingly. The controller may manage the distribution of power from a battery and/or generator to the powertrain and other vehicle accessories to ensure the selected amount for the inverter always remains available.

A transfer case capable of multiple drive ratios (i.e. high and low) in all operating modes of a hybrid all-wheel or four-wheel drive vehicle. The transfer case comprises an input shaft, a primary output shaft, a secondary output shaft, an electric motor, and a planetary gear set. The secondary output shaft is selectively rotatably coupled to the primary output shaft. The planetary gear set has a ring gear rotatably fixed to the input shaft, a planet carrier rotatably fixed to the primary output shaft, and a sun gear rotatably fixed to an output of the electric motor.
