BMW’s self-developed DSC dynamic stability control system is increasingly becoming the core system of the vehicle electronics for all series of models. Initially, in addition to the ABS braking function, the DSC Dynamic Stability Control system "only" needs to enhance the vehicle's driving safety on slippery roads, such as during sudden maneuvers or when the vehicle has an unstable tendency to turn. Dynamic Stability Control restores vehicle stability by applying brakes individually to each wheel. The current DSC dynamic stability control system covers a much wider range of safety and comfort functions. For example, the DSC dynamic stability control system integrates the ASC automatic stability control system and the traction control system, which can control the slip state of the drive wheels by selectively braking the drive wheels that have a tendency to slip, thus affecting the vehicle accordingly. Stabilizing effect. On ice and snow roads, desert or gravel roads, the driver only needs to press a button to put the vehicle into DTC mode, thereby enhancing the vehicle's traction on the above-mentioned roads. At the same time, because the intervention response limit of the DSC dynamic stability control system is slightly extended, the vehicle's traction and driving force also increase, and the driver can enjoy an extraordinary sports driving experience.
Another function of the DSC dynamic stability control system is the CBC cornering braking control system, which can eliminate the tendency of the vehicle to oversteer through asymmetric braking force control when braking slightly when turning.
Unprecedented innovation: real-time brake shoe friction pad wear indicator
DSC dynamic stability control system also integrates another important functional module - BMW dual-stage brake shoe Pad Wear Indicator, which contains a calculation of the remaining mileage of the brake shoe pads and is directly linked to the vehicle's electric steering column lock. Both of these features directly benefit customers: firstly, the ability to more precisely determine when the brake pads need to be replaced, and secondly, the innovative anti-theft security system with electromechanical steering wheel lock automatically responds to the permission command from the vehicle entry system. It was always locked before.
DSC dynamic stability control system with auxiliary functions on the BMW 330i
In addition to the above standard functions, the DSC dynamic stability control system on the six-cylinder engine BMW 330i model also has a series of Additional functions, thereby further improving driving safety and driving comfort, and being able to calculate, apply and adjust the braking force of the wheel brakes more accurately. This will allow customers to experience better deceleration braking effects and greater comfort when they apply the brakes while driving. Secondly, the DSC dynamic stability control system can adjust the braking force according to the operating temperature of the brake, thereby offsetting the attenuation trend of the braking effect under high temperature conditions, so that the braking effect and braking force corresponding to the same brake pedal force remain at the same level.
Build braking time in emergencies and on slippery roads
Another very practical improvement of the DSC dynamic stability control system is to pre-condition the brake pads. Set brake standby function. When the DSC dynamic stability control system predicts that the driver may perform a braking operation (for example, when the driver quickly releases the accelerator pedal), it will immediately reduce the brake fluid flow supplied to the brake caliper to reduce the gap between the brake pads. clearance, so the driver gets faster braking response.
The brake drying function improves the safety of the vehicle on slippery roads: if the DSC dynamic stability control system receives rain information from the rain detector or windshield wiper, it will The predetermined period brings the brake pads into contact with the brake disc, clearing the water film on the brake disc, ensuring that braking is performed quickly enough without any delay.
Better parking comfort
Vehicles with automatic transmissions often experience the so-called "shaking" phenomenon when parking, and the soft parking function of the DSC dynamic stability control system It can eliminate this phenomenon: the system can accumulate the braking force to the appropriate level moments before the vehicle comes to a complete stop, so that the entire parking process is soft and smooth, and no "shaking" occurs at all.
Another comfort function of the DSC dynamic stability control system is called the starting assist function: on a slope road, when the driver releases the brake, the starting assist function can still temporarily keep the vehicle in place. In this way, no matter whether the driver selects forward or reverse gear, the system can make the vehicle start comfortably and smoothly. The vehicle will not slide backwards and the driver does not need to use the parking brake.
