Method and control device for setting the operating point of a slip controller for a wheel of a vehicle

By observing wheel slippage and torque changes, the operating point of the vehicle slip adjuster is dynamically adjusted, solving the problem that the wheel slip adjuster cannot accurately calculate the optimal operating point, thus improving the vehicle's braking and driving efficiency.

AI Technical Summary

Technical Problem

Existing technology cannot accurately calculate the optimal operating point of a vehicle's wheel slip adjuster, resulting in unstable braking or driving torque and low efficiency.

Method used

By observing the slippage between the wheel and the ground, recording the torque change process, and adjusting the working point before and after activating the slip adjuster, the optimal value is optimized with small steps, and the torque is dynamically adjusted in combination with environmental conditions.

Benefits of technology

It enables rapid and precise adjustment of the wheel slip adjuster, improving vehicle braking and driving efficiency and reducing unnecessary oscillations and delayed response.

Abstract

The invention relates to a method for setting a working point (104) of a slip controller (106) for a wheel (110) of a vehicle (100), wherein in the event of activation of the slip controller (106) a torque (112) on the wheel (110) is adjusted from the working point (104) taking into account a slip (108) on the wheel (110), wherein the torque (112) is observed and if the slip (108) meets a predetermined condition the value of the working point (104) is set to an earlier torque (112) value.
