This disclosure details integrated thermal management systems for thermally managing electrified vehicle components. Exemplary integrated thermal management systems may include a thermal module assembly that may be integrated into a front end structure of a flexible modular platform of the electrified vehicle. The integrated thermal management systems may be controlled in a plurality of distinct thermal control modes for thermal managing various subcomponents and for addressing various vehicle auxiliary loads (e.g., passenger cabin heating loads, passenger cabin cooling loads, etc.).

An electric drive axle including a first shaft in driving engagement with an electric motor. A first gear and a second gear are coupled with the first shaft. A second shaft is disposed offset from the first shaft. A third gear is selectively coupled with the second shaft, and the third gear is meshed with the first gear. A fourth gear is selectively coupled with the second shaft, and the fourth gear is meshed with the second gear. A fifth gear is coupled with the second shaft and meshed with a sixth gear coupled with a differential case.

Methods and system are described for changing a driveline gear range from a lower gear range to a higher gear range. The driveline may include two electric machines and four clutches in a four wheel drive configuration. The methods and systems permit a driveline to change from a lower gear range to a higher gear range in a way that may reduce torque disturbances that may result from gear lash.

The present disclosure is directed to electric vehicles. A modular electric vehicle includes an electric vehicle chassis that includes an energy storage device, chassis control circuitry, and one or more communication interfaces disposed on an upper surface of the chassis. The chassis further includes an electric motor, suspension and drivetrain to provide an operating vehicle. An electric vehicle includes an internal combustion engine that drives an electric drive motor for charging a vehicle battery The vehicle may be driven solely by electric power, i.e., the internal combustion engine may provide no drive power to the axles of the vehicle and is used primarily for charging the battery. In some embodiments, electric motors may be coupled to one or both of the vehicle axles and the battery may be coupled to one or both the drive motors under control of a controller.

A commercial automotive vehicle, such as trucks and buses, having an auxiliary shaft associated with an auxiliary engine, a coupling and/or uncoupling device and a method for controlling the coupling and/or uncoupling between a shaft of commercial automotive vehicles and an auxiliary engine associated with the shaft. Specifically, the vehicle has a device that couples and/or decouples the effects of at least one auxiliary engine to a shaft, allowing that, in a coupled state, the shaft receives auxiliary traction from the auxiliary engine or the auxiliary engine acts as a generator of braking energy in a regenerative way and, in a decoupled state, it allows the shaft to rotate freely so that no energy losses occur due to friction of the device components.

A method for multi-speed electric vehicle shift control for damping an acceleration oscillation of the electric vehicle. The method includes determining a percentage of accelerator pedal travel and then retrieving a clutch calibration, a first electric motor calibration, and a second electric motor calibration correlating with the determined percentage of accelerator pedal travel. The method then applies the clutch calibration in actuating a clutch-to-clutch gear ratio change, thereby generating a vibration fluctuation in a first axle, and applies the first electric motor calibration in modulating a first electric motor to dampen the vibration fluctuation. The clutch actuation and first electric motor modulation together produces a first axle torque oscillation. The method applies the second electric motor calibration in modulating the second electric motor to generate a second axle torque oscillation sufficiently out-of-phase with the first axle torque oscillation, thereby dampening the vehicle acceleration oscillation of the electric vehicle.

A variable body vehicle may include a drive module having drive the vehicle wheels provided at a lower portion of the drive module; a body module coupled to an external side of the drive module and forming an internal space of the vehicle; and a battery-mounting portion formed in the drive module or the body module to mount a battery therein, providing electric power to the battery when the battery is mounted, and determining a driving mode of the vehicle by allowing the battery to be selectively mounted in the drive module, wherein a body of the vehicle is variable by a combination between the drive module and the body module according to a purpose of use.

A clutch device includes a plurality of clutches; a plurality of cylinder chambers provided to respectively correspond to the clutches; a pump configured to discharge a hydraulic fluid; a plurality of control valves each of which is configured to control the hydraulic fluid supplied from the pump to a corresponding one of the cylinder chambers; and an oil passage that distributes the hydraulic fluid discharged from the pump, to the control valves. The oil passage includes at least one split point at which the hydraulic fluid discharged from the pump splits. At least one check valve is provided between the at least one split point and at least one control valve among the control valves, the at least one check valve being configured to block a flow of the hydraulic fluid in a direction from the at least one control valve toward the at least one split point.

A multi-purpose vehicle is disclosed that includes a mode change switch for operating a travel mode of a vehicle body and a mode control device for switching the travel mode of the vehicle body in response to an operation of the mode change switch. The mode control device switches the travel mode of the vehicle body between a two-wheel engine driving mode in which only an engine is driven, a two-wheel motor driving mode in which only a motor is driven, a four-wheel hybrid driving mode in which both of the engine and the motor are driven, and an OFF-mode in which none of the engine and the motor is driven.
