ANTI-LOCK CONTROL METHOD AND ANTI-LOCK CONTROL SYSTEM FOR A BRAKING SYSTEM OF A VEHICLE
An antilock control method for a braking system of a vehicle has at least the following steps: upon the presence of a brake request signal, outputting a brake control signal and building up a brake pressure by a braking medium at a wheel brake of a vehicle wheel, measuring a wheel speed of the vehicle wheel to be braked, and determining a wheel slip of the vehicle wheel, upon meeting a first traction criterion or a locking tendency of the vehicle wheel, activating a wheel drive unit and applying a wheel drive torque on the vehicle wheel to increase the wheel circumferential velocity and to reduce the wheel slip until a second traction criterion is met. The brake force introduced in the wheel brake is controlled as a function of the wheel slip by releasing the brake pressure upon satisfying a first traction criterion.

METHOD FOR OPERATING A TWO-WHEELER
A method for operating a two-wheeler. The two-wheeler includes a drive unit and a sensor system, the sensor system including a rotation rate sensor, an acceleration sensor, and a wheel speed sensor. The wheel speed sensor detects at least one measuring pulse per revolution of a wheel of the two-wheeler.

Method of cooperatively controlling regenerative braking step by step for rear-wheel-drive environmentally-friendly vehicle
A method of cooperatively controlling regenerative braking step by step for a vehicle, such as a rear-wheel-drive environmentally-friendly vehicle, performs a braking mode in accordance with a traveling risk degree determined in advance before initiating braking and changes the selectively performed braking mode by re-determining the traveling risk degree during a braking operation. The method includes: a first step of determining in advance the traveling risk degree before initiating braking; a second step of selectively performing any one of braking modes defined based on the traveling risk degree during braking; a third step of re-determining the traveling risk degree after the second step; and a fourth step of changing the selectively performed braking mode based on the traveling risk degree determined in the third step.
VEHICLE CONTROLLER
A vehicle controller applies a braking force to wheels using a hydraulic braking force generating mechanism and sets a vehicle driving torque, which is generated by an engine, to a second torque which is smaller than a first torque in a normal state, when a switch is switched to an ON state in a state in which a vehicle is traveling and an accelerator is turned on. Then vehicle stops, the vehicle controller implements an EPB mechanical operating state using a mechanical parking brake mechanism. When the switch is switched to an OFF sate, the vehicle controller maintains the EPB mechanical operating state until an accelerator pedal operating level reaches “0,” and maintains the vehicle driving torque at the second torque. Then the accelerator pedal operating level reaches “0”, the EPB mechanical operating state is released and the vehicle driving torque is returned to the first torque.
