An auxiliary drive device for a wheelchair has at least one electrically driven drive wheel and a coupling mechanism for coupling the auxiliary drive device to the wheelchair. The electrically driven drive wheel is supported at a steering shaft and freely pivotable with respect to the auxiliary drive device. The steering shaft is arranged such that, when the auxiliary drive device is coupled at a wheelchair ready to be operated, a castor is provided for the electrically driven drive wheel.

The electric vehicle according to the present disclosure calculates motor torque using an MT vehicle model simulating an MT vehicle having a manual transmission and an internal combustion engine. In the first operation mode, an operation amount of a pseudo-clutch pedal and a shift position of a pseudo-gearshift are input to the MT vehicle model to reflect operation of the pseudo-clutch pedal and operation of the pseudo-gearshift in electric motor control. In the second operation mode where the operation of the pseudo-clutch pedal is not needed, an operation amount of a clutch pedal calculated by a driver model is input to the MT vehicle model instead of the operation amount of the pseudo-clutch pedal.

An electric vehicle is configured to be able to perform running by an MT mode that controls an electric motor with a torque characteristic like an MT vehicle having a manual transmission and an internal combustion engine, and running by an EV mode that controls the electric motor with a normal torque characteristic. The electric vehicle includes a mode changeover switch for switching to the running by the MT mode.

An agricultural vehicle is disclosed having a frame with substantially parallel first and second spaced apart side rails extending substantially the length of the frame. First and second cross members extend between said spaced apart side rails in spaced apart relation to each other. The first cross member is equipped with at least one wheel pivotally attached thereto. The second cross member is attached at substantially the rear portion of said frame. The second cross member has two drive wheels rotatably attached thereto and a drive unit mounted on said chassis at said rear portion and independently drivably connected to each drive wheel. First and second drive unit controllers are mounted on different side rails substantially proximal to the front portion of said frame and operable by an operator seated in an operator seat mounted to the frame.

A control system for an electrified powertrain of a battery electric vehicle (BEV) includes an accelerator pedal and a controller configured to determine maximum and minimum values for driver pedal position based on a first position of the accelerator pedal indicative of a first driver pedal position, determine whether the accelerator pedal position remains constant relative to the first position, when the accelerator pedal position does not remain constant and moves to a second position indicative of a second driver pedal position, detect that driver pedal position is increasing when the second driver pedal position is greater than the first minimum value and setting the first maximum value to the second driver pedal position and detect decreasing driver pedal position when the second driver pedal position is less than the first maximum value and setting the minimum value to the second driver pedal position.

An electric go-kart includes a frame and a crossbar. The crossbar is fixed to the frame and extends transversely to a left and right side of the frame. An accommodation box is rotationally coupled to each of the left and right side of the crossbar by a connector. A wheel is installed on an outer end of each accommodation box. A steering rod includes a one end fixed to the connector. A support rod is located at a front end of the frame. A stabilizing wheel is pivotably coupled to a front end of the support rod. A seat is fixed on a top side of the frame. A battery is located within the frame.

The electric vehicle of the present disclosure is configured to use an electric motor as a power unit for traveling. The electric vehicle includes an accelerator pedal, a sequential shifter, and a controller. The controller is configured to change a motor torque output by the electric motor in response to operation of the accelerator pedal and operation of the sequential shifter. The controller is configured to change a change rate of the motor torque at least twice during a preset shift time in response to the operation of the sequential shifter.

A utility table is provided and includes a support table, a plurality of drive wheels, a plurality of guide wheels, and a drive assembly. The support table includes a top frame with a support surface and a pair of side frames extending downward from opposite ends of the top frame. The plurality of drive wheels are positioned along and extend below each of the pair of side frames. The plurality of guide wheels are positioned along an inner surface of the pair of side frames. The drive assembly includes a power source and control system to power the plurality of drive wheels.

A modular vehicle for transporting an individual, the vehicle comprising a main frame comprising a rear end and a front end opposite to the rear end, the main frame defining a longitudinal axis. The modular vehicle comprises at least two seats mounted side-by-side in a single row substantially perpendicular to the longitudinal axis, each of the at least two seats adapted for seating an individual, each of the two seats comprising a seat surface; and a backrest facing substantially toward the front end. The modular vehicle further comprises a driving area at the rear end of the main frame for driving the vehicle.

A power transmission system of a vehicle and a gear-shift control method are provided. The power transmission system includes a first drive assembly (101) and a second drive assembly (102). The first drive assembly includes a first automatic transmission (2) and a first motor (1) connected with the first automatic transmission (2) for outputting power to two wheels of the vehicle. The second drive assembly (102) includes a second automatic transmission (2000) and a second motor (1000) connected with the second automatic transmission (2000) for outputting power to the other two wheels of the vehicle. The first and second automatic transmission are configured to be shifted to a preset gear or a gear adjacent to the preset gear, such that when one of the first and second automatic transmission is shifted to the preset gear, the other one of the first and second automatic transmission is shifted to the preset gear or the gear adjacent to the preset gear.
