A battery arrangement for electrical loads in a vehicle for transporting hazardous waste includes: a battery having at least a first terminal, electrically connectable to an electrical load; a first electrical resistor electrically connected in series to the battery and a second terminal, the second terminal being electrically connectable to the electrical load; and a switch component connected electrically in parallel to the first electrical resistor and connected electrically to the battery. The switch component is controlled such that a first voltage applicable to a third terminal and having a value exceeding a specifiable value closes the switch component and the first resistor is short-circuited. When the applicable first voltage falls below the specifiable value, the switch component opens and the short-circuit is broken.

Battery arrangement for operating electrical loads in a vehicle for transporting hazardous materials

A tachograph and a toll onboard unit as communication partners, which each have a data interface for a data communication via a vehicle data bus to which the communication partners are coupled. The tachograph and/or the toll onboard unit are implemented as a transmitter of data to ascertain a cryptographic check value as a function of user data, which are to be transmitted to the communication partner, and to transmit the cryptographic check value in addition to the user data to the communication partner. The toll onboard unit or the tachograph, respectively, as a receiver of data, is implemented to receive user data and the cryptographic check value associated with the user data from the communication partner and to check the received user data for corruption as a function of the received cryptographic check value.

Tachograph, toll onboard unit, display instrument, and system

In a data transmission method for a tachograph system, digital messages are transmitted between a speed transmitter (MS) and a recording unit (RU). The digital messages contain a pair of keys including a public key (KMP, KRP) and a private key (KMS, KRS), as well as a certificate (ZM, ZR) derived from the respective pair of keys. The public keys (KMP, KRP) and the certificates (ZM, ZR) are mutually verified between the recording unit (RU) and the speed transmitter (MS). If the verification is positive, the speed transmitter (MS) detects sensor data, and a digital message is generated therefrom. In addition, the speed transmitter (MS) generates authentication data for the message in accordance with the pair of keys (KMP, KMS) thereof. The message and the authentication data are transmitted to the recording unit and are processed there in accordance with a validity of the authentication data verified by the recording unit (RU).
