AI Technical Summary

⚠Technical Problem

Existing vehicle control systems face challenges in ensuring precise and safe deceleration when both driver and driver assistance systems are actively involved in longitudinal control, leading to unpredictable and unsafe driving conditions.

⚗Method used

A method that freezes the target deceleration requested by the driver assistance system upon detection of manual braking, allowing the driver to control deceleration independently, and gradually transitions back to assistance system control for smooth vehicle deceleration.

🎯Benefits of technology

Enables precise and safe deceleration control by the driver, preventing initial deceleration reduction and ensuring smooth transitions, enhancing driving safety and comfort.

Abstract

The invention relates to a method (11) for controlling a motor vehicle which can be controlled manually and by a driver assistance system (3). In the method, when a controller of the driver assistance system (3) requests a non-zero target deceleration and simultaneous manual actuation of a brake operating element (5) is detected, the target deceleration requested by the controller of the driver assistance system (3), or a corresponding torque, at the time of the initial detection of this actuation is frozen for as long as the actuation of the brake operating element (5) is detected. The invention also relates to a vehicle system (7) designed to perform the method and to a motor vehicle (1) equipped with such a vehicle system.
