A vehicle includes an antenna system and a controller. The controller may be configured to, responsive to wireless energy, received via the antenna system, exceeding a magnitude and duration indicative of a cellular connection from a nomadic device at a predetermined position in the vehicle in an absence of a connection with the device via a local protocol while the vehicle is in motion, operate a powertrain to limit a speed of the vehicle.

A vehicle power control system includes a driving force control unit configured to limit a driving force during acceleration of a vehicle when the vehicle is in a predetermined power control driving state. The driving force control unit includes a notification unit configured to tactilely notify a driver via a throttle manipulator that a driving force limit state occurs during the acceleration of the vehicle.

The present invention provides a method and system for segmentally limiting the speed of a vehicle. The method comprises: receiving characteristic parameters of a route sent by a vehicle monitoring platform, and respectively expanding a plurality of road segments of the route into a plurality of rectangles; dividing the plurality of rectangles into blocks sequentially; calculating a minimum enclosing rectangle of the at least two rectangles, and counting vertex information of the minimum enclosing rectangle of each block so as to establish a hash table; obtaining an instant longitude and latitude of a moving vehicle, searching in the hash table so as to determine a block where the vehicle is located, and judging a road segment where the vehicle is currently located; and comparing a current speed of the vehicle with a limiting speed of the road segment where the vehicle is currently located, judging whether the vehicle exceeds the limiting speed.

The present disclosure relates to an apparatus for limiting vehicle speed and a method thereof. To prevent a vehicle from exceeding a speed limit to secure safety and improve fuel economy, the apparatus includes: a mode setting device allowing a driver to set any one of a safety mode, a fuel economy mode, and a hybrid mode; a safety speed input device allowing the driver to input a safety speed; one or more processors determining an economical speed on the basis of a driving environment of a vehicle; and a controller limiting a speed of the vehicle on the basis of the safety speed or the economical speed according to a mode set by the driver.

A vehicle speed-limit control method is provided. The method includes determining whether a speed-limit control inactivation condition is satisfied by accelerator pedal engaged when speed-limit control is activated. In response to determining that the inactivation condition is satisfied, a candidate value of an accelerator pedal sensor (APS) and a candidate gear shift stage are determined and a speed margin is determined based on the candidate value of the APS, the candidate gear shift stage and a vehicle speed. The speed margin is compared with a predetermined threshold. The candidate gear shift stage is determined as a transition gear shift stage and the candidate value of the APS is determined as a transition value of the APS when the speed margin is equal to or greater than the threshold. The vehicle is operated based on the transition gear shift stage and the transition value of the APS.

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 shift control system for an industrial vehicle includes a vehicle speed monitor, a vehicle speed limit value setting section, a gear determination section, and a control section. The vehicle speed monitor is configured to monitor and detect an actual vehicle speed of the industrial vehicle. The vehicle speed limit value setting section is configured to set a vehicle speed limit value. The gear determination section is configured to select a transmission gear position of the transmission based on the actual vehicle speed and the vehicle speed limit value. The control section is configured to control the transmission in response to the selected transmission gear position. The gear determination section maintains the transmission in the currently-selected transmission gear position when the vehicle speed limit value is equal to or less than a predetermined threshold value and the threshold value is greater than an upshifting vehicle speed for upshifting the transmission.

Method and apparatus for maintaining a speed of a vehicle within a target speed range. A plurality of coasting profiles are generated for the vehicle, each having an initial speed and a starting point on a predicted vehicle path. Each coasting profile represents a predicted vehicle speed over a time and/or distance from the starting point and is generated based on a geometry of at least a portion of the predicted vehicle path. At least one of the coasting profiles that maintains the speed of the vehicle within the target speed range is identified. A prime mover of the vehicle is controlled to place the vehicle into a coasting mode in accordance with the at least one identified coasting profile. Alternatively, feedback is provided to a user to place the vehicle into a coasting mode, such that the vehicle will coast in accordance with the at least one identified coasting profile.

Method and apparatus for controlling a prime mover of a first vehicle following a first path. A likely speed behaviour of a second vehicle ahead of the first vehicle is estimated based on a predicted path of the second vehicle. At least one coasting profile for the first vehicle is estimated for at least part of the first path and/or the predicted path. At least one of the coasting profiles is determined that meets at least one predetermined coasting requirement. The prime mover may be controlled to place the vehicle into a coasting mode based on the at least one determined coasting profile. Alternatively, feedback is provided to a user to put the vehicle into a coasting mode. The predetermined coasting requirement may include, for example, a minimum coasting mode period, a minimum coasting mode distance, a minimum coasting mode speed, a maximum coasting mode speed, or maintaining the first vehicle's speed with a predetermined tolerance of one or more desired speeds.

When an inclination angle is greater than or equal to a first threshold, a controller determines a displacement of a hydraulic pump from a command vehicle speed based on second pump data and determines a displacement of a hydraulic motor from the command vehicle speed based on second motor data. The second pump data defines the displacement of the hydraulic pump that is smaller than that of first pump data with respect to the command vehicle speed. The second motor data defines the displacement of the hydraulic motor that is smaller than that of first motor data with respect to the command vehicle speed.
