    • A transmission range selector system having a driver interface module, an electronic control module, and an actuator coupleable to an automotive transmission. The driver interface module may be positioned in a plurality of desired transmission gear positions. The desired gear position set at the driver interface module is redundantly sensed by the combination of a rotational position Hall effect sensor and a plurality of discrete position Hall effect sensors. The rotational position Hall effect sensor has a linearly varying output representative of the desired gear position. The Hall effect sensors provide an output to the electronic control module for energizing the actuator to change the transmission gear position to the desired transmission gear set at the driver interface module. The actuator may include multiple motors to provide redundancy and a sensor gear for providing transmission gear position feedback to the electronic control module.
    • 一种具有驱动器接口模块,电子控制模块和可耦合到汽车变速器的致动器的传动范围选择器系统。 驱动器接口模块可以定位在多个期望的变速器档位中。 通过旋转位置霍尔效应传感器和多个离散位置霍尔效应传感器的组合来冗余地感测设置在驾驶员接口模块处的期望档位。 旋转位置霍尔效应传感器具有代表期望档位的线性变化的输出。 霍尔效应传感器为电子控制模块提供输出,用于激励致动器以将传动档位改变为在驱动器接口模块处所需的传动齿轮组。 致动器可以包括多个用于提供冗余的电动机和用于向电子控制模块提供传动齿轮位置反馈的传感器齿轮。
