Disclosed is a method of controlling a two-speed AWD vehicle. According to the present embodiment, control may be performed on an electric vehicle by outputting AND control torque to a propeller shaft by means of detailed torque control in a 4H or 4L mode.

The present application relates to the technical field of computer, in particular to a kind of posture adjustment method, equipment and medium of half wheel foot type obstacle mechanism.The method comprises: controlling half wheel foot type obstacle mechanism to drive to the step front, judge whether half wheel is stuck by step, when half wheel is stuck by step, the half wheel stuck by step is recorded as first half wheel, control mechanism retreats to drive to full wheel drive mode and the direction of first half wheel towards ground, and calculate the retreat distance;Another half wheel is recorded as second half wheel, the distance required for the second half wheel to be in the maximum obstacle height state when the mechanism drives forward to the step front is calculated, and the wheel arm calibration included angle is used as the variable in the forward distance;Based on retreat distance and forward distance, determine wheel arm calibration included angle;Control mechanism based on wheel arm calibration included angle forward drive.Based on the motion information of mechanism itself, the posture of mechanism is quickly adjusted, the influence of external environment is avoided, and the complexity of half wheel foot type obstacle mechanism posture adjustment is reduced.

A method for controlling a two-speed AWD vehicle is disclosed. According to the present embodiment, control of an electric vehicle can be carried out by outputting an AWD control torque to a driveshaft by means of a detailed torque control in a 4H or 4L mode.

The present invention provides an all-wheel-drive vehicle in which heat generation in the transfer case is easily suppressed in a configuration in which a transversely mounted power source is positioned. [Solution] The transfer case includes a gear chamber housing a transfer input gear and a transfer output gear, a coupling chamber housing a coupling member, a first oil passage, and a second oil passage. The first oil passage allows lubricating oil to flow from the upper space of the coupling chamber to the upper space of the gear chamber. The second oil passage allows lubricating oil to flow from the gear chamber to the coupling chamber. As a result, the lubricating oil is cooled by the coupling member that scoops up the lubricating oil in the coupling chamber, and the scooped-up lubricating oil is circulated from the coupling chamber to the gear chamber via the first oil passage. In the gear chamber, the meshed transfer input gear and transfer output gear are efficiently lubricated by the lubricating oil, suppressing heat generation. The lubricating oil that has lubricated the transfer input gear and transfer output gear is circulated from the gear chamber to the coupling chamber via the second oil passage.

A control device for operating a roadbound all-wheel vehicle having a first electric drive motor assigned to a primary axle and a second electric drive motor assigned to a secondary axle, including a control unit configured such that, when a defined dynamic driving mode of the driver is identified based on the driver request gradient during a operating mode with the first motor activated and the second motor deactivated for a predefined time window, an overall setpoint moment characteristic predefined by a new driver request is ascertained. This is set, in accordance with an axle distribution factor that is likewise predefined, by reducing the setpoint moment of the primary motor and by activating and increasing the setpoint moment of the secondary motor, even when the predefined overall setpoint moment characteristic lies below a maximum possible moment of the primary motor.

Embodiments of the disclosure provide an all-wheel drive all-terrain vehicle that includes a substantially rigid frame member that is elongated and includes a battery compartment and a standing area for a rider positioned above the battery compartment. A rear suspension assembly is positioned at a first elongated end of the frame, the independent rear suspension configured to independently support and allow suspension travel to two separate rear wheels and a front suspension assembly is positioned at a second elongated end of the frame that is opposite the first end of the frame, the front suspension assembly configured to independently support and allow suspension travel to two separate front wheels. The vehicle includes an electric motor positioned in each of the front two wheels and each of the rear two wheels and configured to provide motive force thereto, a a battery positioned in the battery compartment, and a a front wheel electric controller positioned in the battery compartment and in electrical communication with the battery to receive electrical power therefrom and in electrical communication with the electric motors positioned in the front two wheels and configured to selectively provide electrical power thereto along with a separate rear wheel electric controller positioned in the battery compartment and in electrical communication with the battery to receive electrical power therefrom and in electrical communication with the electric motors positioned in the rear two wheels and configured to selectively provide electrical power thereto. A rotatable steering column extends upward from the rigid frame member proximate the front suspension assembly, the steering column having a plurality of operational controls positioned that are positioned above a front portion of the standing area.

The present invention relates to a method for heating a traction battery (6) of an electrified vehicle, comprising the steps of determining a first distribution value (CTR1) of a setpoint torque at the wheels between a first set of wheels (3) driven by a first drive unit (2) and a second set of wheels (5) driven by a second electric drive machine (4) powered electrically by the traction battery (6), determining a second distribution value (CTR2) of the setpoint torque at the wheels, determining a temperature of the traction battery (6), and determining a setpoint distribution (CSCTR) of said setpoint torque at the wheels by calculating a centroid of the first distribution value (CTR1) and the second distribution value (CTR2) weighted by the determined temperature of the traction battery (6). The invention relates to hybrid and all-wheel-drive electric vehicles. Figure 1.
