What is multifunction and how did it appear?
A multi-steering wheel is a steering wheel with integrated control buttons that duplicate the functions of the main vehicle controls. The first prototypes of such steering wheels appeared back in 1980s on premium models BMW and Mercedes-Benz, but they became widespread only in 2000s, when electronics became an integral part of even budget cars.
Initially, multifunction steering wheels only allowed you to control the audio system - switch tracks, adjust the volume. Over time, the functionality expanded: buttons appeared for answering calls, management voice assistantohm, activation cruise control and even climate control settings. Today, a multifunction steering wheel is standard for most mid- and premium-class cars.
Interesting fact: the first serial multifunction steering wheel was installed on BMW 7 Series (E32) in 1986. It allowed control of the telephone (which was then a separate device connected to the car) and the audio system. Today such steering wheels seem primitive, but at one time it was a revolutionary solution.
The design and principle of operation of the multifunction steering wheel
From a technical point of view, the multifunction steering wheel consists of several key components:
- 🖥️ Buttons and joysticks — mechanical or touch controls located on the steering wheel spokes.
- 🔌 Electronic control unit (ECU) — processes signals from buttons and transmits them to the corresponding vehicle systems.
- 📶 Wiring and connectors — connect the steering wheel with the on-board electronics. Often used in modern cars
CAN busfor data transfer. - 🔋 Steering column switches (petals) - can be part of the multifunction steering wheel and duplicate the functions of the buttons (for example, changing gears in "tiptronic").
The principle of operation is simple: when you press a button, a signal is sent to the ECU, which determines which command needs to be executed. For example, if you pressed "+" on the volume button, the control unit will send a signal to the audio system and the sound will become louder. In more advanced systems, the multifunction steering wheel can interact with multimedia system (for example, Apple CarPlay or Android Auto), voice assistant and even active safety systems.
It is important to understand that the multifunction steering wheel is not an independent device, but part of the overall electronics of the car. If the car has problems with CAN bus or control unit, the buttons on the steering wheel may stop working. Also multi-function steering wheels are often linked to VIN code car, so when replacing the steering wheel, flashing may be required.
What is a CAN bus?
CAN (Controller Area Network) is a communication standard between electronic components in a car. It allows different systems (engine, transmission, multimedia) to exchange data in real time. If the CAN bus fails, it can lead to malfunctions of the multifunction steering wheel, instrument panel and other electronic systems.
What functions does the multifunction steering wheel perform in modern cars?
The functionality of the multifunction steering wheel depends on the car model and its equipment. Budget cars may have only 4–6 buttons, while premium ones may have more than 20. Let’s look at the main features offered by modern multifunction steering wheels:
| Function category | Examples | On what cars does it occur? |
|---|---|---|
| Audio control | Switching tracks, adjusting volume, selecting source (radio/USB/Bluetooth) | All cars with multifunction steering wheel |
| Phone and voice assistant | Answer/hang up calls, voice dialing, activation of Siri/Google Assistant | Car with Bluetooth and voice control |
| Cruise control | Switch on/off, set speed, resume movement | Car with adaptive cruise control |
| Multimedia system | Menu navigation, application selection (CarPlay/Android Auto), camera control | Cars with touch screens |
| Security systems | Activating lane keeping assist, turning on high beams | Cars with ADAS (advanced driver assistance systems) |
In some premium cars (for example, Mercedes-Benz S-Class or BMW 7 Series) multifunction steering wheel may have touch panels instead of physical buttons. They recognize gestures, such as swiping left or right to change tracks. There are also steering wheels with heated and vibration feedback, which helps the driver “feel” the road.
Important: in some vehicles (eg Tesla Model 3 or Model Y) there is no multifunction steering wheel at all - all functions are controlled via the touch screen. This is a controversial decision, as it distracts the driver from the road.
