摘要： An improved electromechanically drivable spreader unit having an integrated adjustment apparatus for a drum brake, in which the linear motion of brake shoe holders is produced by two ball-ramp devices, wherein a first ball-ramp device includes a first actuation piston arranged for rotation about the axis and a second ball-ramp device includes a second actuation piston arranged for rotation about the axis, and wherein an adjustment apparatus for compensating an actuation travel that increases as a result of wear on the friction linings is arranged in an axially centered position within the housing and substantially between the actuation pistons.

摘要： A brake device for a hydraulic motor vehicle brake system, having a housing, at least one pressure chamber arranged in the housing, filled with a hydraulic pressure medium and bounded by at least one cylinder piston moveable in an axial direction to generate brake pressure. The cylinder piston can be activated mechanically with an activation force by an activation rod unit which is secured to the cylinder piston. In order to provide an improved brake device which is of the generic type mentioned at the beginning and permit a secure connection between the activation rod and the cylinder piston and at the same time mounting which is as easy as possible, it is proposed that the activation rod unit is secured to the cylinder piston by a latching connection, wherein the latching connection is brought about by an axial relative movement between the activation rod unit and the cylinder piston.

摘要： A vehicle system including a vehicle-to-X communication device for vehicle-to-X communication and a processing device for processing data to be sent by vehicle-to-X communication. The processing device is designed to transmit to the vehicle-to-X communication device data which are to be sent. The vehicle-to-X communication device is designed to generate an unsigned vehicle-to-X message using the transmitted data to be sent and to transmit the unsigned vehicle-to-X message to the processing device. The processing device is further designed to sign the transmitted vehicle-to-X message and to transmit the signed vehicle-to-X message to the vehicle-to-X communication device for emission. A corresponding method is also disclosed.

摘要： A motor vehicle controller performs one or more control and/or monitoring functions. The controller includes a processor which determines a first utilization level of the controller during the motor vehicle's travel mode, and a communication interface which receives program code. The program code defines a new control and/or monitoring function of the controller and/or modifies a control and/or monitoring function of the controller. The processor further determines a second utilization level of the controller in the motor vehicle's standstill mode. The program code is the basis for performing the controller's new control and/or monitoring function and/or the modified control and/or monitoring function of the controller, and take the first and second utilization levels as basis for deciding to perform the controller's new control and/or monitoring function and/or the controller's modified control and/or monitoring function in the vehicle's travel mode. A corresponding method for operating such a controller is also disclosed.

摘要： A method of secure data export from an automotive ECU to a requesting entity includes receiving a signed request, the request transmitting a first public encryption key. The signature is verified using a second public key stored in the automotive ECU. Further, the requesting entity is authenticated. Only upon successful verification and authentication the automotive ECU generates a random symmetric key for encrypting the data to be exported. The symmetric key is encrypted using the first public key received in the request, and unencrypted data is deleted. The encrypted data is exported to the requesting entity, which decrypts the symmetric key using a first private key associated with the first public key, and decrypts the data encrypted with the symmetric key.

摘要： The invention relates to a method for improving the control behavior of an electronic motor vehicle braking system which comprises at least a slip control function. Wheel dynamic information which is evaluated as a criterion for initiating a control intervention is used individually for each wheel and is compared with control thresholds for a pressure reduction phase, a pressure maintenance phase, and a pressure buildup phase for generating corresponding braking torques by means of a vehicle braking system. According to the invention, the expected acceleration change of a vehicle wheel is calculated from a pressure change at said wheel, said pressure change being caused by a control intervention; the actual acceleration change at the vehicle wheel, said acceleration change being caused by the pressure change, is determined from measured wheel speeds as wheel dynamic information; and the control behavior of the slip control is adapted when the actual acceleration change deviates from the expected acceleration change by a defined degree such that the deviation is minimized.
