摘要： Various antilock braking systems, devices, and methods using sensorized brake pads are disclosed. In some embodiments, the present disclosure provides a method for improving the performance of an antilock braking (ABS) and anti-slip regulation (ASR) system of a vehicle. The method can include detecting the actual value of the coefficient of friction (e.g., between a tire and the ground), updating the coefficient of friction during braking using the braking torque data derived from at least one braking pad of each wheel, and adjusting brake force. For example, the brake force can be adjusted as a function of and/or to be approximately equal to the value of the actual tire-road friction during braking.

摘要： A method of changing an anti-lock brake system (ABS) control mode includes: determining, by a controller, whether a first stage of an electronic stability control (ESC) of the vehicle is in an off state and a launch control of the vehicle is in an on state, and determining, by the controller, whether a driver intends to slow down an operation of the ABS installed in the vehicle; and when it is determined that the driver intends to slow down the operation of the ABS, comparing, by the controller, revolutions per minute (RPM) of an engine of the vehicle, a vehicle acceleration speed, a vehicle speed, and a steering angle with predetermined threshold values, respectively, and when each of the comparison results is satisfied, changing, by the controller, an ABS general control mode to an ABS sport control mode which slows down the operation of the ABS.

摘要： A method for adjusting brake pressures at pneumatically actuated wheel brakes of a vehicle includes, after an external braking demand, continuously ascertaining, by a brake control unit, in a pressure control mode, at least one differential slip value from measuring signals supplied by speed sensors of the wheels, as the difference between the slip of two axles of the vehicle before releasing the control signals; evaluating the differential slip value with consideration for a predefined or adjustable setpoint differential slip value; and depending on the evaluation, bringing the differential slip value closer to the setpoint differential slip value by adapting at least one control signal.

摘要： A vehicle includes a powertrain configured to transfer energy to a tire and including both an engine and an electric machine. The vehicle also includes a controller configured to charge a traction battery with torque captured by the electric machine in excess of torque required to maintain the departure. The charging is in response to indication of departure from static friction between the tire and a surface during a line lock tire slip event powered by the engine.

摘要： A control method controls a movable member of an excavator including a movable member holding a load, an actuator with electric motor and static brake, a control unit and a motion sensor unit. Static brake and electric motor generate respectively an upper threshold brake force and an upper threshold motor force. The control method includes: an immobilization step: static brake generates the upper threshold brake force and the electric motor is stopped; a slippage detection step: the control unit detects whether electric actuator is moving despite the static brake, in case the electric actuator is moving, a motor energizing step: electric motor generates a motor force equal or superior to upper threshold brake force in a direction opposite to the slippage direction, and after the motor energizing step, a brake release step: the control unit releases the static brake.

摘要： A vehicle brake control device generates rear wheel braking torque by an electric motor by pressing a friction member against a rotating member rotating together with the rear wheel, reduces rear wheel braking torque by controlling the electric motor based on a target energization amount calculated from a slip state quantity of the rear wheel, and rapidly stops electric motor rotation motion based on an adjusted target energization amount calculated from the target energization amount and a slip state quantity of a front wheel.
