AI Technical Summary

Technical Problem

Existing vehicle dynamics control systems fail to effectively stabilize vehicles during rapid acceleration and cornering by addressing wheel slip and lateral force distribution issues before they become perceptible to the driver, leading to oversteer or understeer.

Method used

A system that applies micro-steering impulses, detected by TACTOS sensors, to adjust steering angles and torque based on vehicle speed, yaw rate, lateral acceleration, and road curvature, using symmetrical and asymmetric modes to stabilize tire contact and maintain lateral grip.

Benefits of technology

The system stabilizes vehicle dynamics proactively, enhancing friction utilization and maintaining stability during high-speed accelerations and cornering by correcting slip and lateral force distribution before noticeable deviations occur.

Abstract

The invention relates to a method and a system for stabilizing a motor vehicle during acceleration. Here, a slip condition of one or more wheels is detected based on vehicle dynamics measurements, including wheel speeds, yaw rate, and lateral acceleration. Depending on this, direction-alternating micro-steering impulses or micro-steering torque impulses are automatically applied to a steering system. These impulses exhibit steering angle changes in the sub-degree range and generate a lateral micro-movement of the tire contact patch. The micro-impulses serve to stabilize lateral forces and are executed in two operating modes: a symmetrical mode for acceleration in nearly straight-line driving and an asymmetrical mode with impulse time bias for acceleration in cornering. The impulse parameters are adaptively adjusted to the steering angle, yaw rate, and lateral acceleration.The invention further comprises a corresponding system with sensors, a control unit and an actuator for generating the micro steering impulses.
