Parking control for vehicle windscreen wiper - includes dynamic switch to secure wipers when ignition is switched OFF

摘要

The windscreen wiper control is linked to a simple logic control which operates the wiper motor (10) in conjunction with the settings of the wiper switch (20) and the parking control. If the vehicle ignition is switched off during a wipe cycle the subsequent activation of the ignition restarts the wipers to reach the parking setting. The system allows the driver to stop the wipers in a raised setting so that, e.g. they can hold a frost protection over the windscreen. When the vehicle is started the wipers automatically drop into the parking position.
