One emerging power mobility device (PMD) option that has gained recognition as a means for a cost-effective introduction to power mobility for young children is the battery powered modified ride-on toy car. Many groups, nationally and internationally, have been modifying battery powered ride-on toy cars by adding seating support and a large center placed push button switch for motor activation. The purpose of this technical report is to introduce an enhanced steering and drive system based on proportional control through a joystick. This report offers (1) a technical description of these modifications that allow directional steering and programmable starting and driving velocity, (2) an example of a modified ride on toy, including common seating modifications, and (3) a short summary of results from a group of 7 children under the age of six with complex, severe disabilities. Although proportional joystick modifications are more complex than the common single switch activation, they allow children greater control to achieve self-initiated, self-directed movement that allow play, peer interaction, and exploration in their natural environments, even in the most highly complex cases. All seven children were able to intentionally self-initiate activation of the modified ride-on car and experience the subsequent movement.
一种新兴的动力移动设备（PMD）选择是电池驱动的改装乘用玩具车，它已被认可为一种经济高效地让幼儿接触动力移动的方式。在国内和国际上，许多团体一直在对电池驱动的乘用玩具车进行改装，增加座椅支撑和一个位于中央的大型按钮开关来启动电机。本技术报告的目的是介绍一种基于通过操纵杆进行比例控制的增强型转向和驱动系统。 本报告提供了：（1）对这些改装的技术描述，这些改装允许定向转向以及可编程的启动和行驶速度；（2）一个改装乘用玩具的示例，包括常见的座椅改装；以及（3）一组7名6岁以下患有复杂、严重残疾儿童的结果简要总结。 尽管比例操纵杆改装比常见的单开关启动更复杂，但它们能让儿童更好地控制，以实现自主发起、自主导向的移动，从而能够在自然环境中玩耍、与同伴互动和探索，即使在最复杂的情况下也是如此。所有七名儿童都能够有意地自主启动改装后的乘用汽车并体验随后的移动。
