In a broad respect, vehicles that are capable of making a low- to zero-radius turn using the independent rotation of drive wheels and by turning the non-driving steerable structure or structures (such as wheels) with a steering input device (in some embodiments, the driving wheels also may be capable of being turned). This may be accomplished using a steering system, a speed control system and an integration device (together, a control system) that are configured to work together to provide correct steering in forward and reverse, and, in some embodiments, to reduce the speed of the outboard drive wheel of the vehicle when it enters an extreme turn under constant speed input. Different systems configured for use in such vehicles are included.

Systems for controlling the speed and direction of vehicles, including vehicles that have low to zero turning radius capability.

A method for controlling a vehicle to make an emergency stop of the vehicle providing a camera and an electronic control unit (ECU) at the vehicle. Presence of a road condition is determined at the road along which the vehicle is traveling. Responsive to determining an emergency driving condition while the vehicle is traveling along the road at the road condition, the ECU at least partially controls driving of the vehicle along the road. While the ECU is at least partially controlling driving of the vehicle along the road, and responsive to determining an end of the road condition, a target stopping location is determined ahead of the vehicle at the road along which the vehicle is traveling and after the end of the road condition. The ECU at least partially controls driving of the vehicle to the target stopping location.

A base unit for a lifting vehicle includes a chassis having a chassis plane and a plurality of wheels, each of the wheels being mounted on the chassis by a suspension mechanism having a suspension element and a suspension actuator that controls the position of the suspension element relative to the chassis. The suspension element is arranged to pivot relative to the chassis about an inclined pivot axis in response to actuation of the suspension actuator.

A food cutting device includes a housing and a cutting mechanism, wherein a feeding port is arranged at one side of the housing, and a discharging port is arranged at the other side of the housing; the cutting mechanism includes a cutting portion and a push-pull portion for controlling reciprocating movement of the cutting portion; the cutting portion includes a sliding component, a first cutter and a plurality of second cutters; the sliding component is slidably connected with the housing; both the first cutter and the second cutters are located on the side of the sliding component close to the feeding port, and are detachably connected with the sliding component; and the first cutter is parallel to a sliding direction of the sliding component, and is not parallel to the second cutters. The food cutting device can meet various cutting requirements of people and is efficient.

A steering device includes a handle unit; a steering connection piece; a joint connecting the handle unit to the steering connection piece; a steering connection rod movably connected to the steering connection piece; and a pair of steering rods each rotatably connected to the steering connection rod. In response to a rotation of the handle unit about a first rotational axis, the joint is configured to force the steering connection piece to rotate along with the handle unit about the first rotational axis to cause a shift of the steering connection rod along a first direction perpendicular to the first rotational axis, and the pair of steering rods is configured to rotate about second and third rotational axes, respectively, in response to the shift of the steering connection rod.

A steerable suspension system for a vehicle, especially useful in a self-propelled vehicle that can include a worker-platform and optionally include pick-up, transport, and delivery apparatus for produce bins. The steerable suspension system includes independent pairs of parallel arms, each pair coupled to a single steerable drive-wheel, serving as both a suspension and as a shock absorber, with the parallel-acting pair of arms maintaining the steering-leg in its substantially vertical position relative to a ground surface. This steerable suspension system aids the steerable movement and suspension of the vehicle, while increasing safety and maneuverability, and helps to reduce the number of workers required to operate the vehicle.
