Electronic cruise control system lets you select any preferred cruising speed and, depending on model, even the following distance. It keeps your BMW steadily at this speed, making it easier to stay below speed limits and providing more comfort on long journeys.
An electronic control unit saves the speed at which you are travelling at the moment you activate the system, and holds it constant by continually comparing this saved speed with the actual vehicle velocity. Variations are corrected by adjusting engine power output. This allows you to maintain speeds between approx. 30 km/h and 210 km/h without the need for corrective measures. The advantages are the driver is less distracted and can concentrate fully on the traffic. It also gives him the possibility of relaxing on long stretches and taking his foot off the accelerator.
Depending on the model of your BMW, the system is operated by an easy-to-use lever mounted on the steering column, or by buttons on the multifunction steering wheel. To deactivate cruise control, simply touch the brakes or press the I/O button. Pressing the ‘Resume’ button (resume speed) will automatically reinstate the previously saved speed.
Dynamic cruise control is an electronic cruise control system with an extra braking function. This also includes the Curve Speed Limiter that reduces the speed in curves for comfortable lateral acceleration. At the end of the curve the car accelerates and resumes the original speed. The driver can change this in increments of 1 or 10 km/h. Acceleration and deceleration in two dynamic settings can be controlled by manipulating the lever on the steering column or the paddle on the steering wheel (Comfort Dynamic system).
Active cruise control provides an even more comfortable driving experience. Not only does it maintain the desired speed, it also keeps the selected following distance. A radar sensor with a range of up to 200 m continually measures the distance between your vehicle and the cars in front of it. The sensor also detects if these vehicles are in the same lane as your vehicle or in another.
Your vehicle’s speed will automatically be adjusted according to the speed of the vehicles travelling in front of it or those pulling into its lane. This means there’s an adequate safety margin at any speed.
The complementary Stop & Go function slows the vehicle down or even brings it to a standstill when necessary. Depending on how long the vehicle is stationary, it drives on automatically as soon as this is possible, or when the driver presses the accelerator or a button on the steering wheel. This substantially increases the driver’s comfort when driving in heavy traffic and tailbacks.
