AI Technical Summary
Existing vehicle engine speed controllers struggle to manage wheel slip effectively in conditions of split friction, where wheel speeds differ due to mechanical functions of an open differential, leading to reduced tractive force and safety concerns, especially in situations of traction loss and varying road conditions.
A method and system that adapt the slip target by comparing wheel speed differences and applying a reduction factor to ensure all driven wheels operate below the peak slip, using a modified slip target determined as µ trgt = µ req /K, where K is a function of wheel speed offset and difference, to enhance traction and safety.
Ensures all driven wheels maintain slip below the peak, increasing tractive force and enhancing vehicle safety by managing wheel slip in varying road conditions and loads, while being robust against differential lock engagement.
