摘要： A checking apparatus for checking a number of start-up cycles of a detection device of a motor vehicle includes an electrical switching device for providing an electrical sensor supply for the detection device and includes a contact device for electrically contacting the electrical switching device with the detection device. The electrical switching device has a comparator circuit and, by way of the comparator circuit, a continuous wake up test of the detection device is carried out and thus the number of start cycles is checked.

摘要： A testing device for testing at least one vehicle control unit includes an error feedforward device for feeding forward predefined electrical signals to the at least one vehicle control unit. The error feedforward device has, for electrical signal connection to the at least one vehicle control unit at least one power interface configured for conducting power signals, at least one control signal interface configured for conducting control signals, and at least one data bus interface configured for conducting bus signals. At least the bus lines belonging to the at least one data bus interface are guided separately in the testing device from the electrical lines belonging to the other types of interface.
