A method/control unit for recognizing critical driving situations of a two-wheeled motor vehicle (MV), including: ascertaining an instantaneous slip angle (ISA) and differential slip angle (DSA) of the front/rear wheels; ascertaining an instantaneous roll angle (IRA); comparing the ascertained SAs and DSAs to predetermined values (PV) of maximum allowable slip angles (MASA) or DSAs; comparing the IRA to PVs of a maximum allowable roll angle (MARA); and generating a criticality signal when one of the ISAs is greater than the PV of the MASA, at least one of the instantaneous DSAs is greater than the PV of the maximum allowable DSA, and the IRA is greater than the PV of the MARA. Critical driving situations are recognized with the method, and measures for stabilizing the two-wheeled MV or other safety-enhancing measures may be performed. Special driving situations (driving over low- patches or braking while negotiating a curve) may be considered.

The present subject matter relates to monitoring traction for a motor vehicle. A vehicle speed and a circumferential speed of the at least one driven wheel are sensed using sensors of the motor vehicle. A control deviation is determined based on a difference of a setpoint wheel slip and an actual wheel slip. The control deviation is input to the PID traction controller. A slip acceleration is determined based on a difference of a wheel acceleration of the at least one driven wheel and a vehicle acceleration determined from the sensed vehicle speed and a circumferential speed of the at least one driven wheel. Using the PID traction controller, a drive torque of the at least one driven wheel is determined from a sum of a P-component, an I-component, and a D-component of the PID traction controller. The drive torque back to the at least one driven wheel.

The disclosure provides an anti-lock brake device including an oil pressure tank, a valve, and a movable component. The oil pressure tank has an accommodation space, an oil inlet channel, and an oil outlet channel connected to the accommodation space. The valve is slidably located in the oil inlet channel and for sealing or opening an oil inlet of the oil inlet channel. The movable component is located in the accommodation space and has a connecting channel corresponding to the oil inlet and an oil outlet of the oil outlet channel. When the movable component is slid to a depressurized position, the movable component is moved away from the valve for sealing the oil inlet, a first volume is produced between the connecting channel and the oil inlet, and a second volume, smaller than the first volume, is removed from between the connecting channel and the oil outlet.
