A materials handling vehicle comprises a processor, a throttle, and a zone sensing subsystem coupled to the processor. The processor, responsive to the zone sensing subsystem detecting that the materials handling vehicle is in a restricted operational zone, controls the materials handling vehicle by applying a maximum vehicle operational limit of the materials handling vehicle to a magnitude that is at or below an operational limit of the restricted operational zone. Further, the processor overrides the maximum vehicle operational limit based on application of a throttle neutral action.

Provided is a traveling apparatus including an adjusting mechanism configured to adjust a wheel base length between a front wheel and a rear wheel by an action of the user being transmitted, a command accept unit configured to accept a command for traveling forward or backward from the user, and a control unit configured to, while the command accept unit accepts the command for traveling forward, control a driving unit to drive the traveling apparatus to travel forward based on a forward target speed associated with the wheel base length in such a way that the greater the wheel base length, the greater the forward target speed becomes, and while the command accept unit accepts the command for traveling backward, control the driving unit to drive the traveling apparatus to travel backward based on a backward target speed associated with the wheel base length.

A throttle control system and method for use with a vehicle. The throttle control system receives an input voltage from a vehicle throttle controller. The throttle control system prepares a throttle signal and provides the throttle signal to the throttle to force deceleration to a selected speed or constrain acceleration to a selected value. Preparing the throttle signal may follow detection of maximum threshold values of speed or input voltage. The maximum threshold values may be specific to the location of the vehicle. The throttle signal and the maximum threshold values may be defined with reference to the input voltage, vehicle speed, vehicle location, or other parameters. The throttle signal may force deceleration or constrain acceleration incrementally to mitigate loss of vehicle throttle controller responsiveness to driver commands. The throttle signal may be an output voltage provided to a vehicle electronic control module.

A broadcast of a signal is received at a first system from a second system at a first time. From the signal, a location of a target associated with the second system and a velocity of the target are determined relative to a location of the first system and a velocity of the first system. At the first system, using the location and the velocity of the first system and using the location and the velocity of the target, a likelihood is computed of a collision between the first system and the second system. A notification is sent from the first system about the likelihood of collision responsive to the likelihood of collision exceeding a threshold likelihood.

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 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 smart key device for use with a vehicle is disclosed. The smart key comprises: an interface configured to communicatively couple with a controller of the vehicle; and a non-volatile storage module configured to store a deactivation message configured to cause the controller of the vehicle to deactivate and/or limit the functionality of the vehicle. The deactivation message may include an indication of a time period or distance driven after which the vehicle will be deactivated. A vehicle controller; a smart key write device and associated methods are also disclosed.

Vehicle-mounted device includes an inertial measurement unit (IMU) (8) having at least one accelerometer or gyroscope, a GPS receiver (6), a camera (10) positioned to obtain unobstructed images of an area exterior of the vehicle (16) and a control system (20) coupled to these components. The control system (20) re-calibrates each accelerometer or gyroscope using signals obtained by the GPS receiver (6), and derives information about objects in the images obtained by the camera (10) and location of the objects based on data from the IMU (8) and GPS receiver (6). A communication system (18) communicates the information derived by the control system (20) to a location separate and apart from the vehicle (16). The control system (20) includes a processor that provides a location of the camera (10) and a direction in which the camera (10) is imaging based on data from the IMU corrected based on data from the GPS receiver (6), for use in creating the map database (12).
