Problems solved by technology

However, this solution does not appear to be satisfactory if additional electronic components need to be provided in the circuit
[0010] Further, given that for each switch of the module, a dedicated input to the microcontroller needs to be provided, newer modifications and future versions require modification of the main board and its components, thus resulting in high development costs

Embodiment Construction

[0028] A non-limiting exemplary embodiment of the present invention will be described below with reference to the accompanying drawings.

[0029] figure 1 A rear perspective view of the control equipment 1 is shown, in particular for the top of a steering column of a motor vehicle.

[0030] This equipment 1 is mounted on a steering column 3 which carries a steering wheel 5 at its rear end.

[0031] By way of example, in figure 1 As can be seen in , on the opposite side, the control equipment has a lighting control lever 7 and a windscreen wiper control lever 9 , which are mounted on a central support 11 .

[0032] As will be described in detail below, each lever takes the form of a control module, in other words, on the one hand it has a built-in dedicated mechatronic system that translates the movement of the user into a change in the state of the switch and on the other hand its There is a mechatronic connection system, in particular for supporting the main board of the c...

Abstract

The invention concerns a control assembly, in particular for motor vehicle steering column top portion (1), comprising several switching modules (7; 9; 13; 15) and a microcontroller (19) mounted on a motherboard (17) for interpreting a switching state based on the identifier of the module to deliver an appropriate control signal, the motherboard (17) having several connecting locations (E1, E2, E3, E4), and each module (7; 9; 13; 15) having an identical number N of predetermined tracks (L1, L2, L3, L4, L5, ID1, ID2; CS1; CS2; CS3; CS4) to be connected to tracks associated with the motherboard(17). The corresponding exit tracks (L1, L2, L3, L4, L5, ID1, ID2) of each switching module (7; 9; 13; 15) are interconnected and connected together on the same input of the microcontroller (19), andthe control assembly comprises for each location (E1, E2, E3, E4) means for activating reading of a switching state of a module connected at said location, said activating means being monitored by the microcontroller (19).

Description

technical field [0001] The invention relates to a control arrangement, in particular for the top of a steering column of a motor vehicle. Background technique [0002] Control equipment for the top of the steering column of a motor vehicle is widely known in the prior art. [0003] In the same system, such equipment combines several electronic switching modules for eg controlling headlights, windscreen wipers, audio functions, telephone functions or even a speed regulator. [0004] Over the years it has been observed that vehicles are increasingly more customized with respect to their equipment, which is why there is a need to be able to adapt the switch module around the steering wheel efficiently to the equipment present on the vehicle. [0005] Therefore, the modularity of the control equipment is an important factor for the ability to easily adapt a basic equipment with several optional modules to the needs expressed by the user and to provide the control equipment at a...
