Provided is a speed limiter, wherein a vehicle speed is detected, and a speed limit displayed on a speed sign is detected based on an image captured by a front monitoring camera. A speed difference between the vehicle speed and the speed limit is calculated, and an accelerator sensitivity gain is set using the speed difference as a parameter. Then an accelerator opening degree is corrected with the accelerator sensitivity gain to obtain a pseudo accelerator opening degree. A target throttle opening degree is set based on the pseudo accelerator opening degree and an engine rpm.

A motor vehicle speed control system having a distance sensor operates in a first mode when the vehicle is traveling on a clear stretch of road in which a predetermined desired vehicle speed is set. In a second mode when the vehicle is following another vehicle, a predetermined minimum distance from a selected target object is set. The target object is selected by a first selection process that screens out stationary objects. When a defined condition prevails, the first mode switches into a third mode in the form of deceleration, wherein a second selection process is started which also evaluates stationary target objects. Until a target object is selected, the vehicle travels on a clear road with deceleration initiated which is reduced relative to following another vehicle. If a target object is selected by the second selection process, the system switches over without delay from the third mode into the second mode.

A speed regulator 120 and a method for operating it. The speed regulator guides an engine system 130 in a vehicle towards a target speed v des , whereby the vehicle assumes an actual speed v act which describes a zeroing pattern towards the target speed v des . Priming of the speed regulator 120 is effected on the basis of knowledge about a road section ahead of the vehicle, whereby the magnitude of at least one fluctuation in the zeroing pattern relative to the target speed v des is reduced. A zeroing pattern with fewer overshoots and undershoots is thus achieved, resulting in reduced fuel consumption.

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. 1. A powered wheelchair comprising:a frame;a lift supported by the frame;a seat supported by the lift, the lift configured to move the seat between a lowered position and a raised position;a drive wheel coupled to the frame and rotatable about a drive wheel axis;a drive configured to apply a torque to the drive wheel;an arm assembly including an arm member that is pivotably coupled to the frame and a front wheel coupled to the arm member proximate a distal end of the arm assembly;a rear wheel coupled to the frame, wherein the front wheel, drive wheel and rear wheel contact a reference plane when the wheelchair is in an at rest position on a flat horizontal surface; a first position relative to the frame in which the arm member is rotatable through a first range of rotation relative to the frame, and', 'a second position relative to the frame in which the arm limiter is positioned to abut the arm member to limit rotation of the arm member through a restricted range of motion relative to the frame that is less than the first range of rotation; and, 'an arm limiter supported by the frame and configured to inhibit rotation of the arm member, the arm limiter havinga linkage assembly coupled to the lift mechanism ...
