Embodiment Construction

[0029] figure 1 A schematic diagram of a vehicle 100 with a device 110 for determination according to one exemplary embodiment is shown. Vehicle 100 is a motor vehicle, for example a commercial vehicle, in particular a truck or the like. Vehicle 100 has a plurality of wheels 102 . exist figure 1 In the illustration, only one wheel 102 is explicitly shown by way of example for reasons of clarity. The wheel 102 may rotate at an angular velocity Ω that is associated with the rotational speed of the wheel 102 .

[0030] Vehicle 100 has device 110 for determination or determination device 110 . Determining device 110 is designed to determine a rotational speed of wheel 102 or wheels 102 of vehicle 100 . According to the exemplary embodiment shown here, the determination device 110 has a detection device 120 , a first controller 130 and a second controller 140 . Detection device 120 is shown here for only one wheel, wherein a person skilled in the art recognizes that detection...

Abstract

The invention relates to an apparatus (110) for determining a rotational speed of at least one wheel (102) of a vehicle (100). The apparatus (110) has a detection device (120) for detecting an angular velocity (omega) of the wheel (102) that correlates with the rotational speed. The detection device (120) is designed to provide an electrical detection signal (125) depending on the detected angular velocity (omega). The apparatus (110) also has a first control unit (130) having a first measuring device (132) for measuring the detection signal (125). The first control unit (130) is electrically connected to the detection device (120). The apparatus (110) further has a second control unit (140) having a second measuring device (142) for measuring the detection signal (125). The second control unit (140) is electrically connected to the detection device (120). The detection device (120) can be electrically switched, or is electrically switched, between the first measuring device (132) and the second measuring device (142).

Description

technical field [0001] The invention relates to a device and a corresponding method for determining the rotational speed of at least one wheel of a vehicle. Background technique [0002] In highly automated driving, for example, the driver of the vehicle does not have to be permanently seated in the driver's seat and is available for corrective intervention. Therefore, traditional backup solutions cannot be used in emergencies. If the main braking system is not available, the redundant braking system should take over the driver's duties. In order to be able to form, for example, an ABS function in a redundant situation, both braking systems should generally read in the signals of the rotational speed sensors of the wheels. Contents of the invention [0003] Against this background, the object of the present invention is to provide an improved device for determining the rotational speed of at least one wheel of a vehicle and an improved method for determining the rotation...
