Pinch detection system

A method of detecting a pinch of a moveably arranged closure member of an open-roof assembly, the method comprising:

• providing a control unit operatively coupled to a drive assembly configured to control movement of the closure member, wherein the control unit comprises a pinch detection unit configured to detect a pinch of closure member with an object, the pinch detection unit comprising a first pinch detection system and a second pinch detection system;
• detecting a first pinch with a soft object using the first pinch detection system, the soft object having a stiffness lower than a first predetermined threshold;
• detecting a second pinch with a hard object using the second pinch detection system, the hard object having a stiffness higher than a second predetermined threshold;
• when the second pinch detection system detects the second pinch, adapting a configuration setting of the first pinch detection system to configure the first pinch detection system to detect the second pinch with the hard object;
• and
• after adapting the configuration setting of the first pinch detection system, detecting the second pinch with the hard object using the first pinch detection system;
• and
• determining that each pinch has occurred when the first pinch detection system has detected a physical property of the closure member or a motor driving the closure member.

A non-transitory, tangible computer-readable storage medium storing computer executable instructions for instructing a control unit to control movement of a closure member of an open-roof assembly, the executable instructions configured to perform a method comprising:

• detecting each pinch with each soft object using a first pinch detection system, each soft object having a stiffness lower than a first predetermined threshold;
• detecting each pinch with each hard object using a second pinch detection system, each hard object having a stiffness higher than a second predetermined threshold;
• when the second pinch detection system detects each pinch with each hard object, adapting a configuration setting of the first pinch detection system to configure the first pinch detection system to detect each pinch with each hard object;
• after adapting the configuration setting of the first pinch detection system, detecting each pinch with each hard object using the first pinch detection system;
• and
• determining that each pinch has occurred when the first pinch detection system has detected a physical property of the closure member.
