Abstract
Method for detecting the position of a wiper arm (5) for a system (1) for wiping a vehicle window (3), comprising the steps consisting in: a) measuring or estimating (35) at least one parameter for determining the maintenance or service position, b) comparing (37) the measured or estimated value of said parameter with a reference value or a range of reference values, and c) determining, from the results of the comparison, whether the wiper arm is in maintenance or service position.
Claims15
A method for detecting the position of a wiper arm for a system for wiping a vehicle window, the system comprising:
- at least one wiper blade borne by said wiper arm that can be displaced from a so-called maintenance position in which said wiper blade is not in contact with said window, to a so-called service position in which said wiper blade is in contact with said window,
- at least one motor for driving said wiper arm, and
- at least one control unit for controlling said motor, the method comprising:
- measuring or estimating at least one parameter for determining the maintenance or service position;
- comparing the measured or estimated value of said parameter with a reference value or a range of reference values;
- and
- determining, from the results of the comparison, whether said wiper arm is in maintenance or service position.
A system for wiping a vehicle window, comprising:
- at least one wiper blade borne by said wiper arm, the at least one wiper blade configured to be displaced from a maintenance position in which said wiper blade is not in contact with said window, to a service position in which said wiper blade is in contact with said window
- at least one motor for driving said wiper arm;
- at least one control unit for controlling said motor;
- and
- a device for:
- a) measuring or estimating at least one parameter for determining the maintenance or service position,
- b) comparing the measured or estimated value of said parameter with a reference value or a range of reference values, and
- c) determining, from the results of the comparison, whether the wiper arm is in maintenance or service position.
