System for controlling a sunroof of a vehicle
A system is provided for gaining access to a sunroof of a vehicle, in particular a car, including a sunroof control unit ( 19 ) and a sunroof actuation switch ( 27 ), in particular, for actuation of opening and/or closing and/or tilting of a sunroof. The sunroof actuation switch has one switch contact ( 28 ) or a plurality of switch contacts, wherein the sunroof control unit ( 19 ) and the sunroof actuation switch ( 27 ) are re-configured to communicate data, such as programming and/or reprogramming data and/or parameter setting data and/or diagnostic data, from and/or to the sunroof control unit ( 19 ) through the one switch contact ( 28 ) or at least one of the plurality of switch contacts.
1. A system for gaining access to a sunroof of a vehicle, comprising:
a sunroof control unit ( 19 ) and a sunroof actuation switch ( 27 ) operatively connected to the sunroof of the vehicle for actuation of opening and/or closing and/or tilting of the sunroof, the sunroof actuation switch ( 27 ) having one switch contact ( 28 ) or a plurality of switch contacts; and
a diverter switch ( 20 ) including a single pole, double throw (SPDT) switch for diverting a line ( 18 a ) between the actuation switch ( 27 ) and the control unit ( 19 ) so that said line ( 18 a ) can be connected to either a first input means ( 21 ) of the control unit for receiving an actuation command opening or closing or tilting of the sunroof, or to a second input and/or output means ( 23 ) of the control unit ( 19 ) for transmitting and/or receiving the data;
wherein:
the sunroof control unit ( 19 ) and the sunroof actuation switch ( 27 ) are configured to communicate programming and/or reprogramming data and/or parameter setting data and/or diagnostic data, from and to the sunroof control unit ( 19 ) through the one switch contact ( 28 ) or at least one of the plurality of switch contacts
the actuation switch ( 27 ) comprises a removable switch module ( 15 ) including a bezel for allowing access to at least one inner switch connector including a wire of the switch ( 27 );
the removable switch module ( 15 ) comprises one or a plurality of switch buttons ( 16 ) for generating the opening and/or closing and/or tilting commands; and
the diverter switch ( 20 ) is controllable by the actuation switch ( 27 ) by holding the actuation switch in a predetermined position for a predetermined time period by a series of pulses on at least one line.
2. The system of claim 1 , characterised by a snap-in and/or screwing mechanism for a mechanical connection of the switch module ( 15 ) with the remaining parts of the switch ( 27 ).
3. The system of claim 1 , characterised in that the diverter switch ( 20 ) is controllable by the actuation switch ( 27 ) by holding the actuation switch in a predetermined position for more than 3 s by a series of pulses on at least one line.
4. The system of claim 1 , characterised in that the control unit ( 19 ) comprises a microprocessor.
5. The system of one claim 1 , characterised by an external control and/or monitoring and/or diagnose unit ( 26 ) being connectable to at least one of the switch contacts ( 28 ) for data transmission.
6. The system of claim 1 , characterized by the vehicle being a car.
7. A method of communicating with a sunroof control unit ( 19 ) of a vehicle comprising a step of communicating programming and/or reprogramming data and/or parameter setting data and/or diagnostic data, from and/or to the sunroof control unit through a switch contact ( 28 ) of a sunroof actuation switch ( 27 ) for actuation of opening and/or closing and/or tilting of a sunroof, the sunroof control unit comprising a diverter switch ( 20 ) which is controllable by the actuation switch ( 27 ) by holding the actuation switch in a predetermined position for a predetermined time period by a series of pulses on at least one line so that said line ( 18 a ) can be connected to ether a first input means ( 21 ) of the control unit for receiving an actuation command opening or closing or tilting of the sunroof, or to a second input and/or output means ( 23 ) of the control unit ( 19 ) for transmitting and/or receiving the data;
wherein:
the actuation switch ( 27 ) comprises a removable switch module ( 15 ) including a bezel for allowing access to at least one inner switch connector including a wire of the actuation switch ( 27 ); and
the removable switch module ( 15 ) comprises one or a plurality of switch buttons ( 16 ) for generating opening and/or closing and/or tilting commands.
8. A use of a switch contact ( 28 ) of a sunroof actuation switch ( 27 ) for actuation of opening and/or closing and/or tilting of a sunroof, for communicating programming and/or reprogramming data and/or parameter setting data and/or diagnostic data, from and to a sunroof control unit, the sunroof control unit comprising a diverter switch ( 20 ) which is controllable by the actuation switch ( 27 ) by holding the actuation switch in a predetermined position for a predetermined time period by a series of pulses on at least one line so that said line ( 18 a ) can be connected to either a first input means ( 21 ) of the control unit for receiving an actuation command opening or closing or tilting of the sunroof, or to a second input and/or output means ( 23 ) of the control unit ( 19 ) for transmitting and/or receiving the data;
wherein:
the actuation switch ( 27 ) comprises a removable switch module ( 15 ) including a bezel for allowing access to at least one inner switch connector including a wire of the actuation switch ( 27 ); and
the removable switch module ( 15 ) comprises one or a plurality of switch buttons ( 16 ) for generating opening and/or closing and/or tilting commands.
