What do ESP electronic stability systems (ABS, MSR, ASR, EDS, HBA, DSR, RBS) mean?

MSR (motor-controlled sliding retainer) engine resistance torque control system (also known as accelerated slip adjustment). In some special cases (high-speed gear shifting or sudden release of the throttle when driving on the road with low adhesion coefficient), the engine will produce a large resistance moment, which will lead to instability or even sideslip of the vehicle. At this time, MSR can automatically reduce the engine resistance torque and ensure the stability of the vehicle. It is a function to prevent the adhesion coefficient of the driving wheel road surface from dropping suddenly after the sudden resistance of the engine is large. For example, if you suddenly accumulate oil in the snow, MSR will control the engine to prevent the traction from falling too fast to ensure the driving stability of the vehicle. MSR is the abbreviation of German Motro schlepmonregelung, which means engine traction control, equivalent to EDTC engine resistance-torque control.

ASR (Accelerated Slip Adjustment) drives (wheels) to accelerate slip adjustment. Belonging to an automobile active safety device. Also known as traction control system, it can prevent vehicles, especially high-powered vehicles, from slipping when starting and accelerating again, thus maintaining the stability of the vehicle's driving direction.

RBS acceleration slip regulation is used with ABS***. Without ABS, there would be no RBS.

Hydraulic brake assist system. When the control system detects that the driver is braking hard, the system will automatically start and increase the braking force to shorten the braking distance; Under normal braking conditions, the system will not start (that is, when the driver just wants to slow down and doesn't want to stop, it doesn't help)

DSR is an auxiliary tool for downhill driving. It keeps the vehicle speed at the speed set by the on-board computer. The greater the downhill slope, the stronger the braking effect of DSR on vehicles. When driving on a flat road or uphill, the braking effect of DSR is little or non-existent.

RBS acceleration slip regulation is used with ABS***. Without ABS, there would be no RBS.
