Infotainment. All nine ID.4 models are equipped with the Discover Pro navigation system and 10-inch display as standard. All models above the ID.4 City and ID.4 Life come with the Infotainment package. Its highlights include the Comfort mobile phone interface, which is able to connect a smartphone to the vehicle’s electronic system and charge it inductively. The standard App-Connect function enables media to be streamed via a smartphone, which can be embedded in its native environment using Android Auto, Apple Car Play and Mirror Link. In the Infotainment Plus package (which comes with the ID.4 Tech and ID.4 Max), the navigation system has a 12-inch display.
We Connect Start. The We Connect Start online services connect the ID.4 to the owner’s smartphone and traffic infrastructure. One area of We Connect Start comprises the navigation services, which include Online Traffic Information and an online map update function. On long journeys, the Online Route Calculation function included with the navigation services is particularly useful: it plans charging stops so that the driver can reach their destination as quickly as possible. The Charging Stations service can search for and locate charging stations in the surrounding area. This directory is updated on a regular basis and the separate details – such as occupancy levels and prices – are even updated continuously.
The second area of We Connect Start consists of the vehicle-related services. ID.4 customers can use the app to control the charging process and air conditioning system remotely from their smartphone or check the battery’s charge level and the vehicle’s range.
New electronics platform. The ID.4’s electronic intelligence is based on a network architecture that Volkswagen designed from scratch for the MEB. In terms of hardware, two central high-performance computers known as ICAS (In-Car Application Servers) are the main components. They are responsible for a number of tasks that are usually performed by separate control units in conventional models.
The software architecture in the ID.4 follows the principle of local servers: designed to be a broad service platform, it significantly simplifies the exchange of data and functions between the systems involved. This flexibility makes it easy to integrate new data packages, though these are subjected to a strictly protected authentication process. Basic driving functions such as drive and brake control remain in their separate control units. One of the major strengths of the new network architecture is the system update functionality, which enables the software in the central control units to be updated over a mobile network and ensures the ongoing enhancement of many functions.
IQ. Drive assist systems. Volkswagen has consolidated its assist systems under the name IQ. Drive. These make driving more relaxed and can help to avoid accidents or mitigate their consequences. With its full equipment package, the ID.4 uses a front radar, front camera, four area view cameras, two rear radars and eight ultrasound sensors to collect data from the surrounding area.
Standard systems. The ID.4 is equipped with the lane keeping system Lane Assist as standard. Its steering intervention helps to stop the vehicle leaving its lane unintentionally. Front Assist monitors the area in front of the vehicle and responds with warnings and braking interventions to warn the driver of impending collisions with other road users. With the oncoming vehicle braking when turning function, the vehicle supports the driver when turning across the oncoming lane, while swerve support provides counter steering assistance to help the driver avoid obstacles. The acoustic Park Distance Control function is able to avoid parking collisions or reduce the level of damage using the automatic manoeuvre braking function. The speed limiter is also included in the ID.4’s standard equipment.
Another technology that every ID.4 has on board is called Car2X, which allows the car to exchange information about local hazards with other vehicles and the traffic infrastructure – via the wireless standard WLAN p. The maximum distance here is 800 metres, with warning transmission taking only milliseconds. Car2X is currently active from a speed of 80 km/h, but is also intended to improve safety and traffic flow in urban traffic in the future. The more vehicles that have the new technology, the greater the benefits – a classic principle of swarm intelligence.
Assist package. The Assist package contains a rear view camera system, an anti-theft alarm and the keyless locking and starting system Keyless Access. The proactive occupant protection system closes the windows and tensions the seat belts immediately before an imminent crash in order to protect the vehicle occupants.
Assist Plus package. The top-of-the-range models ID.4 Tech and ID.4 Max are equipped with the Assist Plus package. The Adaptive Cruise Control ACC stop & go system regulates the distance to the vehicle in front and also analyses road signs and navigation data. It automatically reduces the vehicle’s speed as the vehicle approaches town boundaries, for example, and then accelerates again as it leaves the urban area.
Travel Assist combines longitudinal and lateral vehicle control and can be activated directly via a button on the steering wheel. Within the limits of the system, it performs the majority of acceleration and braking operations for the driver and uses gentle steering intervention to help the vehicle to stay in the middle of the lane. Side Assist monitors traffic behind and next to the ID.4. If the driver is about to change lane in a critical situation, a warning is issued. Emergency Assist brings the vehicle to a stop if the person behind the wheel is no longer able to do so in a medical emergency. The cameras in the Area View system provide a detailed image of the area around the vehicle from a bird’s eye view.
