Cruise control with a brake function featured as standard, Active Cruise Control with Stop & Go as an option.
“Regular” cruise control with its braking function acts on engine management, the choice of gears and the brakes in order to keep the car at a specific speed determined by the driver in advance. The system permanently registers the car’s lateral ac -celeration and, if necessary, reduces road speed by intervening in engine management and the brake system, thus avoiding any loss of comfort or unpleasant behaviour in bends. It also helps the driver on downhill gradients – particularly when towing a trailer – by intervening in the brakes whenever necessary.
Active Cruise Control with Stop & Go gives the driver even greater support and further benefits. Available as an option, this system also features automatic distance control allowing the driver to comfortably cruise along on the motorway or country roads in stop-and-go traffic at very low speeds while consistently keeping an appropriate distance from the vehicle ahead.
Particularly in slow-moving traffic, this sophisticated control system offers the driver a significantly higher standard of motoring comfort under otherwise unpleasant conditions.
The driver nevertheless retains his responsibility and remains in control of the car, intentionally being required after stopping for more than 3 seconds to briefly push down the gas pedal or press the Resume button in order to accelerate again. And the driver is also able to influence Active Cruise Control at any time, increasing or reducing the speed of the car by giving gas or applying the brakes. Active Cruise Control with Stop & Go uses the latest generation of radar sensors, enabling the driver to choose from four different distance levels. As soon as the distance he has set to the vehicle ahead is no longer maintained, the system corrects the speed of the car by intervening in drivetrain management and applying the brakes. Indeed, the system is even able to bring the car to a standstill whenever required, again without requiring any intervention on the part of the driver, holding the car back as long as required.
The maximum stopping power generated by Active Cruise Control with Stop & Go is 4 metres/sec², and is limited at higher speeds to a more comfortable level of 2.5 metres/sec².
Should intervention by the driver be required because the driver ahead is applying the brakes particularly hard, the driver will be alerted by optical and acoustic signals to act accordingly, the activation thresholds of the Brake Assistant are lowered, and DSC Dynamic Stability Control is set to its Brake Standby function. This enables the driver, by responding quickly, to reduce the risk of a bumper-to-bumper collision.
The front-to-rear collision warning system is readily available independently of Active Cruise Control with Stop & Go.


Always remaining precisely on course: Lane Change Warning and Lane Departure Warning.
For the first time, the driver of the new BMW 7 Series has the choice of Lane Departure Warning helping him to remain alert at the wheel. The system detects any deviation from the right track and gives the driver a discreet but clear signal by generating vibrations on the steering wheel.
Lane Departure Warning is made up of a camera installed near the interior mirror on the windscreen, a control unit serving to compare data, and a signal processor generating discreet but clear vibrations on the steering wheel. Whenever the driver has indicated his intention to change the lane or his direction by setting the direction indicator, there is no warning signal. The camera in the windscreen monitors road markings at least on one side of the road and their position versus the car, as well as the edge of the road/lane. It is able to look ahead about 50 metres or 165 feet and also operates at night whenever the headlights are switched on, thus making Lane Departure Warning a very practical feature in many situations on the road.
Lane Change Warning available for the first time in a BMW helps the driver overtake with extra safety and in greater style.
Radar sensors at the rear of the car monitor traffic conditions on the adjacent lanes, covering an area extending from the blind angle on the lane directly next to the car up to a distance of 60 metres or almost 200 feet behind the vehicle. A triangular symbol lighting up permanently on the base of the exterior mirror shows the driver that there is another vehicle in this critical area.
As soon as the driver sets the direction indicator with the intention to change to another lane, he will be warned in such a situation by this LED signal flashing on and off. An additional warning comes from the steering wheel starting to vibrate, like the signal generated by the Lane Departure function.

World debut in the new BMW 7 Series: Speed Limit Display.
In combination with a navigation system and Lane Change Warning, the BMW 7 Series offers yet another exclusive function: the Speed Limit Display informs the driver at all times of the speed limit allowed on the route he is currently taking.
This function enhances driving comfort particularly on long distances, always informing the driver of the current speed limit without requiring him to constantly watch out for traffic signs.
Instead, a camera fitted near the interior mirror permanently monitors the signs by the road as well as variable speed limit signs on overhead displays (for example on the motorway), comparing this data with the data already saved in the navigation system.
Even when the speed limit has changed on account of temporary conditions – for example in the case of roadworks – priority is given to the data recorded by the camera. Other, individual factors are likewise taken into account: The speed allowed is presented to the driver in the instrument cluster or, as an option, in the Head-Up Display, thus significantly reducing the risk of breaking the speed limit by mistake.
