摘要： Embodiments of the present invention relate to powered vehicles (e.g., lawn mowers) and, more particularly, to a control system for use with such a vehicle. In one embodiment, the vehicle includes a power source such as an internal combustion engine and one or more drive control levers incrementally movable between a neutral position and a maximum velocity position. The system may also include a velocity profile control system having an adjustment member that permits altering a ratio between control lever movement and velocity of an associated drive member or wheel. Thus, the system may alter a maximum potential velocity of the vehicle while the drive control lever(s) are positioned in the maximum velocity position without varying an output level of the power source.
摘要翻译：本发明的实施例涉及动力车辆（例如，割草机），更具体地，涉及一种用于这种车辆的控制系统。在一个实施例中，车辆包括诸如内燃机的动力源和可在空档位置和最大速度位置之间递增移动的一个或多个驱动控制杆。该系统还可以包括速度分布控制系统，其具有允许改变控制杆运动与相关联的驱动构件或车轮的速度之间的比率的调节构件。因此，当驱动控制杆位于最大速度位置时，系统可以改变车辆的最大潜在速度，而不改变动力源的输出水平。

摘要： A parking brake actuator system for an outdoor power equipment unit, such as a riding lawn mower, comprises a reversible electric motor that drives a gear reduction assembly. The gear reduction assembly rotates an output shaft at a speed slower than the speed of rotation of the motor. The output shaft has opposite ends that are linked by a pair of actuating rods to a pair of parking brakes. As the motor is rotated in reverse rotary directions, the connecting portions of the rods that are coupled to the parking brakes are moved in opposite, straight line directions to move the parking brakes between brake disengaged and brake engaged positions.

摘要： An electrically powered actuator system is provided for engaging and disengaging the parking brake system of an outdoor power equipment unit, such as a riding lawn mower. The actuator system includes a solenoid that is coupled to the parking brake(s) of the unit by one or more link arms. When the solenoid is deenergized and the armature of the solenoid is extended, the link arms rotate the parking brake(s) into their engaged positions. When the solenoid is energized and the armature of the solenoid is drawn inwardly into the solenoid housing, the link arms rotate the parking brake(s) into their disengaged positions. The solenoid is energized and deenergized by a control system responsive to various switches that detect various operational conditions of the unit, such as the presence of the operator in the seat of the unit and/or the placement of the unit's twin stick propulsion and steering controls in their inboard positions.

摘要： A control system for a BBC on a mower comprises a pivotal bail and a pivotal housing that is linked to the BBC. If a push member on the housing is pushed inwardly from the side of the housing before the bail is pivoted, then a pin moves to a blocking position behind the bail. Subsequent pivoting of the bail will pivot the housing to actuate the BBC. A channel in the housing frictionally grips the bail to prevent rebound of the bail when a spring force resets the housing and the bail to their initial positions after the operator releases the bail. Movement of the push member also closes an interlock switch which will kill operation of the engine if a grass discharge outlet on the mower is uncovered.

摘要： A ground speed control system for an outdoor power equipment unit comprises a slidable handle grip that moves up and down on a handle to decrease and increase the ground speed, respectively. A pivotal control lever is provided on the handle grip. The pivotal lever includes a toothed sector gear. A toothed rack is fixed to the handle. Normally, the sector gear and toothed rack are out of engagement with each other during sliding motion of the handle grip. However, if the operator pivots the control lever to engage the sector gear with the rack, cooperation between the teeth of the sector gear and the teeth of the rack will move the slidable handle grip further down the handle to provide a temporary speed increase and will also lock the handle grip to the handle to provide cruise control capability. The handle grip is U-shaped and has two legs telescopically received inside the open upper ends of a pair of spaced handle tubes.
