Driving safety system with safe transmission channel

A method for a plausibility check of a wheel speed signal received by a wheel speed sensor via an unsecured transmission channel in a driving safety system for a motor vehicle, wherein the method comprises:

• receiving the wheel speed signal from the wheel speed sensor, wherein the wheel speed signal represents an actual wheel speed, and wherein the wheel speed signal is transmitted via the unsecured transmission channel;
• receiving a locomotion signal that correlates with an actual vehicle speed, the locomotion signal being transmitted via a secure transmission channel;
• and
• comparing the wheel speed signal received via the unsecure transmission channel with the locomotion signal transmitted via the secure transmission channel to check the wheel speed signal for plausibility,
• wherein comparing the wheel speed signal with the locomotion signal comprises performing a setpoint-actual value comparison,
• wherein the locomotion signal represents a setpoint, and
• wherein the wheel speed signal represents an actual value;
• and
• generating an error message based on a detection of a deviation.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by a driving safety system, cause the driving safety system to:
• receive a wheel speed signal from a wheel speed sensor, wherein the wheel speed signal represents an actual wheel speed, and wherein the wheel speed signal is transmitted via an unsecured transmission channel;
• receive a locomotion signal that correlates with an actual vehicle speed, the locomotion signal being transmitted via a secure transmission channel;
• and
• compare the wheel speed signal received via the unsecure transmission channel with the locomotion signal transmitted via the secure transmission channel to check the wheel speed signal for plausibility,
• wherein the one or more instructions, to compare the wheel speed signal with the locomotion signal, cause the driving safety system to:
• perform a setpoint-actual value comparison,
• wherein the locomotion signal represents a setpoint, and
• wherein the wheel speed signal represents an actual value;
• and
• generate an error message based on a detection of a deviation.
