AI Technical Summary

Technical Problem

Modern vehicles' braking systems are vulnerable to malicious software attacks that can trigger unnecessary or dangerous emergency braking, posing a significant safety risk.

Method used

A braking system with multiple receiving units (online and offline) and a comparator to validate braking situations using both internal and external data, ensuring reliability by requiring consistent confirmation from at least two units before activating the brake controller.

🎯Benefits of technology

The system enhances safety by preventing false or malicious-triggered emergency braking, utilizing diverse and independent data sources to ensure accurate detection of necessary braking scenarios, thereby reducing the risk of accidents.

Abstract

Braking system (1, 1a, 1b) for a vehicle (2), comprising the braking system (1, 1a, 1b), a brake control (17) configured to control an actuator (18) controlling the braking force, a wireless communication unit (5) configured to receive external data through an external device, and an online receiving unit (4, 4a) configured to receive vehicle data from one or more internal vehicle devices via one or more first input channels (8a, 9a, 10a) as well as at least partially the external data via the wireless communication unit (5), wherein the online receiving unit (4, 4a) is further configured to recognize a necessary braking situation as online information from the received external data and vehicle data, and a first offline receiving unit (6), wherein the first offline receiving unit (6) is configured toat least part of the identical vehicle data from one or more vehicle-internal devices via one or more second input channels (8b, 9b, 10b), and to recognize the necessary braking situation as a first offline information from the received vehicle data, at least a second offline receiving unit (19), wherein the at least one second offline receiving unit (19) comprises one or more sensors arranged to detect at least the traffic situation in the direction of travel as traffic data, and wherein the at least one second offline receiving unit (19) is configured to recognize the necessary braking situation as a second offline information from the received traffic data, and a comparator (11) configured to compare the online information and the first and second offline information and to generate a positive or negative result based on the comparison.and, in the event of a positive result, to transmit this to the brake control (17) for activation of the brake control (17).
