摘要:
A system (10), controller (20), and method (400) for detecting moisture on a windshield (12) that uses an isolated electrode (16) coupled to a windshield (12). The isolated electrode (16) is configured to exhibit an electrical impedance indicative of moisture present on a surface of the windshield (12). The controller (20) is configured to determine an electrode impedance value corresponding to the electrical impedance exhibited by the isolated electrode (16) for detecting moisture on the windshield (12). By using an isolated electrode (16), the system (10) is simpler and less expensive than other systems that have at least one electrode providing a return path for another electrode. Also, a way to use the isolated electrode (16) for both detecting moisture on the windshield (12), and heating the windshield (12) is described.
摘要(中):
一种用于检测使用耦合到挡风玻璃(12)的隔离电极(16)的挡风玻璃(12)上的湿气的系统(10),控制器(20)和方法(400)。 隔离电极(16)被配置为呈现指示挡风玻璃(12)的表面上存在的水分的电阻抗。 控制器(20)被配置为确定对应于用于检测挡风玻璃(12)上的湿气的隔离电极(16)所呈现的电阻抗的电极阻抗值。 通过使用隔离电极(16),系统(10)比具有至少一个电极为另一电极提供返回路径的其它系统更简单且更便宜。 此外,描述了使用隔离电极(16)来检测挡风玻璃(12)上的湿气并加热挡风玻璃(12)的方式。
