Abstract: A method for controlling the tightening torque of an electromechanical brake for a motor vehicle, the brake including an electric motor provided with a rotary shaft intended to drive mechanical brake-clamping mechanisms. The method includes steps of acquiring data from a wheel speed sensor that takes a characteristic measurement of the speed of at least one of the wheels of the vehicle, determining, according to the data from the wheel speed sensor, a deceleration indicator characteristic of the acceleration of the vehicle, regulating the tightening torque according to the deceleration indicator.

Abstract: A vehicle braking system includes a brake pedal, master cylinder, a braking circuit with a wheel cylinder, and a brake pressure generator. A pedal feel simulator is coupled to the master cylinder output side through a switchable valve, the pedal feel simulator providing a reaction force. An isolation valve closes to isolate the braking circuit from the master cylinder and the simulator circuit. A primary pressure sensor generates a braking request signal responsive to the brake pedal. A controller activates the brake pressure generator to apply a braking force to the wheel cylinder based on the braking request signal. The controller identifies an abnormal value from the primary pressure sensor and couples the pedal feel simulator with a secondary pressure sensor within the braking circuit to determine whether the abnormal value indicates a primary pressure sensor malfunction or a malfunction of the pedal feel simulator or the switchable simulator valve.

Abstract: In a method for stabilizing the driving behavior of a tractor-trailer combination, a tilting inclination variable is obtained and a tilting limit is determined on the basis of the tilting inclination variable and is prescribed to a vehicle movement dynamics control system. A vehicle movement dynamics control device carries out the method. In order to improve the stabilization of the driving behavior of tractor-trailer combinations with different loads of the individual vehicles, the respective tilting inclination variable is determined at a plurality of vehicles of the tractor-trailer combination, and the value of the tilting inclination variable for the determination of the tilting limit which is decisive for the determination of the tilting limit is obtained from the tilting inclination variables.

Abstract: When a braking operation amount is reduced, a stiffness value representing a ratio of variation in actual pressing force of a friction member to a variation in actual position of an electric motor are sequentially computed. The actual position when the stiffness value changes from being higher than or equal to a predetermined value to being lower than the predetermined value is stored as a candidate position. When a duration during which the stiffness value is lower than the predetermined value is shorter than a clearance corresponding value corresponding to a transmission member clearance in a state where the candidate position is stored, the candidate position is deleted. When the duration during which the stiffness value is lower than the predetermined value exceeds the clearance corresponding value, the stored candidate position is determined as a reference position at which the friction member and the rotary member begin contacting each other.

Abstract: An electromagnetic brake pedal feel simulation system may simulate the feel of a manual brake pedal when force is applied to a power-assist brake pedal mounted to an arm. The electromagnetic brake pedal feel simulation system may include an electromagnetic movement resistance device. The device may mechanically couple to the power-assist brake pedal pad or arm and may apply a controllable amount of force against a braking force that is applied to a power-assist brake pedal pad that is a function of the amount of a drive signal current. The electromagnetic movement resistance device may include a pair of magnets having both of their north or south poles facing each other and that come closer together as force is applied to the power-assist brake pedal pad. At least one of the magnets may be an electromagnetic to which the drive signal current may be applied. The electromagnetic brake pedal feel simulation system may include a brake pedal position sensor that senses the position of the power-assist brake pedal pad or arm. A controller may be electrically connected to at least one electromagnet and to the brake pedal position sensor. The controller may cause the amount of the drive signal current to vary based on the position of the power-assist brake pedal pad or arm, as sensed by the sensor.

Abstract: A method is provided for operating an electromechanical vehicle brake system having an ESP module and at least two brake circuits, each brake circuit comprising high and low pressure switching valves, a low pressure storage device, and two wheel brakes. The method comprises, in advance of a possible breaking procedure and based on a trigger factor, filling the low pressure storage device with an amount of brake fluid at a first pre-pressure. Subsequently, an ESP pump is used to fill the vehicle brake system, including the low pressure storage device, with an adjustable amount of final pre-pressure. All valves are closed when the final pre-pressure is achieved. The method further comprises, during a braking procedure, opening respective inlet valves of the wheel brakes and supplying at least a part of the final pre-pressure to at least one wheel brake of the vehicle brake system.
