An electrical passenger car, the electrical passenger car including: at least two electrically driven motors; motor control electronics; sensors; and wheels, where the wheels include a first front wheel and a first back wheel, where the first back wheel has a radius at least 15% greater than a radius of the first front wheel, and where the motor control electronics control the at least two electrically driven motors to provide a greater torque to the front wheel than to the back wheel, or where the motor control electronics control the at least two electrically driven motors to provide a greater torque to the back wheel than to the front wheel.

A utility machine, such as an outdoor power equipment unit such as a lawn mower, includes a work unit performing work in addition to motive power for the utility machine and a trailer occupied by an operator in a standing position. The operator may seamlessly step onto the trailer to operate the machine in stand-on mode and step off the trailer to operate the machine in walk-behind mode. The trailer remains in the deployed condition in both stand-on mode and walk-behind mode.

A hybrid hydro-mechanical/electronic steering system for a track vehicle, where the driver system can simultaneously use hydro-mechanical connections and electronic (steer by wire) connections to steer a track vehicle such as a tank, where safeguards for safety and reliability include seamless transition between electronic to hydro-mechanical control and vice versa, such that the system can be used in a single or double chassis track vehicle and is adaptable for autonomous driving.

A system and method for steering a machine. The system may comprise a controller configured to receive a steering command and determine a target angular turn rate for the body and a target turn direction for the body. The controller may be further configured to determine a steering mode based on a transmission output torque, the steering mode including Traction-steering, Assisted-steering or Implement-steering. When the steering mode is Assisted-steering, the controller is configured to steer the machine in the target turn direction and at the target angular turn rate by (a) moving an implement from a first position to a second position and (b) diverting or removing power from a first ground engaging traction member. When the steering mode is Implement-steering, the controller is configured to move the implement from a first position to a second position to steer the machine in the target turn direction and at the target angular turn rate without diverting or removing power from the first ground engaging traction member.

A method and apparatus for providing an off-road feature of a vehicle includes determining that the vehicle is in an off-road area based upon a location of the vehicle and sensed terrain characteristics at the location. Upon determining that the vehicle is in the off-road area, the vehicle monitors parameters for enablement of the off-road feature of the vehicle. The off-road feature is enabled in response to the parameters being within a predetermined range based upon a number of transitions between an enabled state and a disabled state within a predetermined time being less than a transition threshold. Parameter monitoring for enablement of the off-road feature is ceased upon determining that the vehicle has moved from the off-road area to an on-road area.

An electrical passenger car, the electrical passenger car including: at least two electrically driven motors; motor control electronics; sensors; and wheels, where the wheels include a first front wheel and a first back wheel, where the first back wheel has a radius at least 20% greater than a radius of the first front wheel, and where during acceleration of the electrical passenger car, the motor control electronics receive signals from the sensors and provide traction control delivering more power to one of the at least two electrically driven motors accordingly.

Self-propelled vehicles for forming bales of crop or forage material are disclosed. The self-propelled baling vehicles include independently driven real wheels and front caster wheels that allow the baling vehicle to turn with a counter-steer profile. In some embodiments, the center of mass of the formed bale is toward the rear of the vehicle to improve the weight distribution of the vehicle.
