The present disclosure includes a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A vehicle interfaced smartphone control device for limiting phone distraction while driving includes a docking station, which selectively engages a smartphone of a driver of a vehicle so that the smartphone is operationally engaged to the docking station. The docking station is mountable to an interior element of the vehicle so that the smartphone is accessible to the driver. The docking station is operationally engageable an electronic control module of the vehicle. First and second programming code are selectively positionable on the electronic control module and the smartphone, respectively. The first programming code enables the electronic control module to operate the vehicle with at least one operational aspect of the vehicle being limited. The second programming code enables the smartphone, when operationally engaged to the docking station, to continuously signal the electronic control module to operate the vehicle without limiting any operational aspects of the vehicle.

A method for operating a compactor on a compressible surface includes: moving the compactor on the compressible surface; receiving an operating speed of the compactor; determining whether an obstacle is present in a path of the compactor; and changing the operating speed to a creep speed if the obstacle is in the path of the compactor. The creep speed is sufficient to prevent the compactor from forming dips in the compressible surface.

A cruise control interlock system detects a current set of conditions for a vehicle, compares the current conditions with cruise control interlock conditions (e.g., an adjustable threshold state of a windshield wiper system), and executes a process to deactivate the cruise control system. The process to deactivate functionality of the cruise control system may include presenting a notification to the operator to alert the operator to an upcoming automatic deactivation or to encourage the operator to deactivate cruise control. The process also may include a vehicle de-rate process (e.g., reducing vehicle speed) to induce the operator to deactivate cruise control. Deactivation of cruise control may be postponed in some situations, such as when the vehicle is ascending an uphill grade or where doing so may deactivate an active downhill speed control function.

Embodiments of the present disclosure include a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, and one or more pairs of arm assemblies. The arm assembly includes a wheel configured to move from a first spatial location when the wheel chair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters that can selectively engage the arm assembly dependent on the position of the arm assembly and surface conditions of ground and can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A recreational vehicle includes a seatbelt sensor configured to detect when a seatbelt is in an engaged position or a disengaged position and an engine control module in communication with the seatbelt sensor to automatically limit a maximum speed of the vehicle to a reduced maximum speed limit upon detection of the seatbelt is in the disengaged position.

In a vehicle speed limiter in which an electronic control unit that controls a drive force of an engine based on at least an accelerator opening controls a drive force of a vehicle so that a vehicle speed does not exceed a speed limit, the electronic control unit is configured to allow the vehicle speed to be equal to or higher than the limit vehicle speed and control the drive force generated by the engine based on the accelerator opening when the accelerator opening becomes a value equal to or larger than a increase reference value larger than a decrease reference value after the accelerator opening has decreased to a value equal to or smaller than the decrease reference value within a predetermined time from a time point when the vehicle speed limitation is released during the vehicle speed limitation being executed by the speed limiting control.

A vehicle has been proposed that is equipped with a processing system coupled to different sensors that may anticipate and mitigate risks leading to vehicle-pedestrian incidents. In some aspects, the processing system identifies, using a plurality of sensors and external vehicle sources over a wireless network, data elements indicating that the vehicle is a potential hazard to a pedestrian. Using the elements, the processing system may determine values of a pedestrian hazard level (PHL) that correspond to successively increasing risks. Where the PHL meets a threshold, the system may employ countermeasures to proactively mitigate the risks of pedestrian incidents.

A system for regulating speed of a vehicle along a road surface, the system including: at least one controller; at least one throttle sensor in communication with the at least one controller; at least one brake sensor in communication with the at least one controller; at least one gear sensor in communication with the at least one controller; at least one speed sensor in communication with the at least one controller; at least one motor in communication with the at least one controller; and at least one energy source in communication with the at least one controller and the at least one motor; wherein the at least one controller further includes a proportional integral and derivative controller; and at least one retardive braking system in communication with the at least one controller and controlled by the proportional integral and derivative controller.

A vehicle driving system to be provided in a vehicle includes a touch sensor and a control unit. The touch sensor is to be provided in the steering operation device and configured to measure a fluctuation in electrostatic capacitance. The control unit determines, based on information from the touch sensor, whether a driver of the vehicle is in a steering-holding state or in a non-steering-holding state. After a detection of a first fluctuation that is a fluctuation in the electrostatic capacitance occurring before a malfunction of the touch sensor, the control unit determines that the driver is in the non-steering-holding state even if the information from the touch sensor to the control unit indicates that the driver is in the steering-holding state.
