摘要： A sensor assembly includes a sensor element and at least two control units, each having an evaluation and control unit and an energy source. In a first control unit, a first evaluation and control unit is connected to a first energy source, and in a second control unit, a second evaluation and control unit is connected to a second energy source. The at least two control units and the sensor element are interconnected by at least one separate interconnection unit. Each interconnection unit connects a first connection of an associated sensor element to the first energy source and/or to the second energy source. A second connection of the sensor element is earthed. A sensor current flowing through the sensor element is modulated at least with information about a detected measured variable. The first evaluation and control unit and/or the second evaluation and control unit evaluate(s) the detected sensor current.

摘要： A braking apparatus includes a controller disposed in a first area to which first power is applied from a first power supply and configured to output a control signal for controlling a braking force applied to a wheel, a driver disposed in a second area to which second power that is greater than the first power is applied from a second power supply and configured to output a driving signal for driving a motor in response to the control signal, and an isolator configured to insulate the controller from the driver and transmit the control signal to the driver. A terminal through which the first power is applied to the first area is separated from a terminal through which the second power is applied to the second area. A ground of the first area is separated from a ground of the second area.

摘要： A method for electronically controlling a brake unit having two brake systems in an automatically controllable vehicle combination includes inputting a request signal for automatic electronic activation of service brakes in a tractor vehicle brake system of a tractor vehicle and/or a trailer brake system of a trailer of the vehicle combination, wherein an automatically requested vehicle setpoint acceleration and/or an automatically requested vehicle setpoint velocity to be implemented by the respective service brakes are transmitted via the request signal. The method further includes monitoring and checking plausibility of the request signal to establish whether the automatically requested vehicle setpoint acceleration and/or the automatically requested vehicle setpoint velocity are or can be implemented completely or faultlessly by the respective service brakes. The method additionally includes outputting a trailer redundancy control signal at the trailer brake system under certain conditions.

摘要： An electric brake system includes a plurality of electric brake devices. A control device of each electric brake device includes: an abnormality determination section that determines whether there is abnormality in supply of power from a power supply device to the electric brake device; and a redundant function control section that, when the abnormality determination section has determined that there is abnormality in supply of power, controls the braking force by using an auxiliary power supply in accordance with a predetermined condition. The redundant function control section controls the braking force by using the auxiliary power supply at least when a desired braking force cannot be output even with all the electric brake devices for which the abnormality determination section has determined that there is no abnormality in supply of power, as the predetermined condition.
