| BMW Dynamic Traction Control ?????? DTCWed, 10 Sep 2008 22:17:11 -0700 by LienderNickDynamic Traction Control (DTC) allows for sports-style driving dynamics even when DSC is controlling stability and when wheel traction is higher.Dynamic Traction Control (DTC) is a sub-function of the Dynamic Stability Control (DSC) system that can be turned on and off. DTC has two major uses: to regulate traction and to enable sports-style driving while providing active stability control.If the front wheels are stuck in snow and cannot spin properly, this leads to slip on the rear wheels (when they spin faster than the front wheels, generally a sign that performance has been exceeded) and DSC acts to change engine output: the power needed for forward movement is reduced. Switching to DTC has a positive effect on this situation, as traction is improved without a loss of power.When DTC is on, it helps the driver alleviate the situation enough for DSC's measures to become effective. The driver retains complete control over the vehicle. Related: bmw dynamic traction control ?????? dtc ?? ?? tech | |

| BMW Hill Descent Control (HDC) ??????Thu, 04 Sep 2008 17:33:25 -0700 by LienderNickHill Descent Control (HDC) holds the vehicle steadily at a pre-determined speed, helping with the job of brake control so that the driver can concentrate completely on steering. This makes the potentially difficult task of driving down a steep hill or over rough ground easy.Hill Descent Control (HDC), a driver assistant system in four-wheel drive vehicles, can be activated with the press of a button. When travelling at less than 35 km/h, HDC assists you by reducing you to a constant speed of approx. 7 km/h, or 6.5 km/h when reversing. The brake lights come on automatically to warn any drivers situated behind your BMW. The accelerator and tempomat can be used to vary speed between crawling speed and 25 km/h, but if you want, you can of course move faster or slower: HDC then goes into standby mode. It is deactivated once your speed goes above 60 km/h. HDC is particularly helpful when driving on changeable, loose or slippery downhill surfaces, such as gravel, snow or grass. Together with ABS, it ensures excellent stability while still preventing the wheels from locking if you apply the brakes on a slope. This prevents the vehicle from skidding and permits you to retain control over the steering.When HDC deactivates, it goes into fade-out mode, gradually reducing braking force and giving you enough time to again take full control of your speed.

| BMW Electronic Damper Control (EDC) ?????Thu, 28 Aug 2008 18:32:02 -0700 by LienderNickElectronic Damper Control (EDC) reduces variations in wheel load, ensures tyres have excellent traction and counteracts bodyshell movement regardless of the weight your automobile may be carrying - and regardless of the state of the road's surface. EDC can even help shorten braking distances, meaning you enjoy outstanding comfort along with the best in BMW on-road safety.Sensitive sensors constantly monitor all factors influencing the vehicle's behaviour and occupants' comfort, including road conditions, load changes and vehicle speed. In a fraction of a second, the signals are analysed by the EDC microprocessor and orders are sent to the actuators on the shock absorbers, which, with the help of magnetic valves, are variably adjusted to provide optimal suspension.Thanks to Electronic Damper Control, the tendency for the nose to dip when braking is practically eliminated. The influence of potholes and unevenness on the road surface is reduced to minimum. Whether you're behind the wheel or relaxing in the rear of the cabin, EDC delivers a remarkably smooth and comfortable ride. Related: bmw electronic damper control edc ?? tech ?? ????? | |

| BMW Night Vision. ????Sat, 16 Aug 2008 01:20:32 -0700 by LienderNickWith BMW Night Vision, driving at night becomes much safer and more comfortable. With the help of this cutting-edge technology, you can identify potential obstacles or roadside pedestrians quickly, keeping you securely in control.BMW Night Vision uses an infrared camera with a 36° wide-angle lens - up to three times wider than other systems. It creates an image of the surroundings based on heat: warm objects such as animals or pedestrians appear as bright shapes. This image is displayed in black and white on the display monitor. The camera can detect forms up to 300 metres away, giving the driver plenty of warning about forthcoming obstacles. Driving at 100 km/h, for example, this equals seven seconds: more than enough time to take evasive action if required. A digital zoom feature can zoom in on objects far away if driving with higher speeds.The panning function turns the camera image automatically when the vehicle is cornering, enabling the driver to detect obstacles in and beyond the approaching bend. A pedestrian crossing the road, for example, is safely revealed. Entering dark courtyards or garages, or driving on winding roads at night, is easier and safer.With BMW Night Vision, BMW becomes the first premium European automobile manufacturer to use Far Infrared (FIR) technology, which has the benefit of a greater area of coverage than Near Infrared (NIR). FIR also offers superior recognition of persons and animals, making it easier to distinguish potential dangers earlier. It does not require active infrared illumination or any additional infrared lights. Related: bmw night vision. ???? ?? ?? tech | |

| BMW Self-levelling suspension ??????????Sun, 10 Aug 2008 19:45:46 -0700 by LienderNickKeep on the level even when you're towing a heavy load: Self-levelling suspension adjusts the height of your vehicle's rear axle for better driving dynamics and safety.Carrying heavy luggage or towing a trailer can cause a vehicle's tail to sink downwards. BMW's self-levelling suspension system counteracts with problematic tendency by inflating pneumatic cylinders integrated in the rear axle assembly that lift the chassis higher. Pneumatic pressure is maintained by auxiliary compressors which are electrically operated. The compressors run independently of the engine and can be adjusted individually if required - for example, when carrying an uneven load.Maintaining a steady chassis level is essential to your BMW's dynamic handling. Towing or transporting heavy loads can lead to uneven tyre wear. Furthermore, oncoming drivers can be blinded by the upwardly-tilted headlight beam. BMW self-levelling suspension eliminates these dangers Related: bmw self-levelling suspension ?????????? ???? ?????? ?? ?? tech ?? safe | |

| BMW Dynamic Brake Control DBC ????????Mon, 04 Aug 2008 00:59:45 -0700 by LienderNickBMW Dynamic Brake Control DBC ????????When, in an emergency, you apply the brake pedal quickly and with force but without really further increasing brake pressure, Dynamic Brake Control (DBC) instantly builds up maximum brake pressure, bringing your BMW more quickly to a halt.Even when the driver fails to press on the brake pedal with adequate force, DBC ensures the braking distance will be a short as possible. The DBC control unit adjusts braking pressure to suit the current speed of the vehicle and the brake's level of wear. Furthermore, the DBC computer is networked with the vehicle's other chassis control systems, such as Dynamic Stability Control (DSC) and the anti-lock brake system (ABS), which work together to ensure the highest levels of driving safety.Dynamic Brake Control (DBC) supports the driver actively and reliably when braking in an emergency. By electronically monitoring the speed and pressure with which the driver applies the brake pedal, it is able to recognise an emergency braking situation - and instantly ensures that full braking power is applied to the wheels. This automatically puts the brake force into the ABS range of control.This process ensures that the stopping distance is not lengthened unnecessarily by abrupt braking. Whether the driver applies the brakes quickly or slowly, the system responds to the driver's actions automatically and ends brake pressure buildup via DBC.
