Abstract
A method and a device for controlling traction in a motor vehicle in which a maximum transmittable driving torque is calculated using operating parameters of the vehicle and its drive unit. One of these parameters is a quantity indicating the turning performance of the vehicle in cornering, such as the yaw or transverse acceleration of the vehicle.
Claims9
A method for controlling traction in a motor vehicle, comprising the steps of:
- when a skidding tendency of at least one driving wheel of the motor vehicle occurs, adjusting a driving torque of a drive unit of the motor vehicle;
- determining a maximum transmittable torque as a function of first operating parameters of the motor vehicle, second operating parameters of the drive unit, and a value indicative of a turning performance of the motor vehicle in cornering;
- and
- when a traction control is engaged, reducing the driving torque to the maximum transmittable torque determined in the determining step.

A device for controlling traction in a motor vehicle, comprising:
- an analyzer unit adjusting an engine torque when a skidding tendency of at least one driving wheel of the motor vehicle occurs and determining a maximum transmittable torque for driving as a function of first operating parameters of the motor vehicle, second operating parameters of a drive unit of the motor vehicle and a value indicative of a turning performance of the motor vehicle in cornering, the analyzer unit reducing a driving torque of the drive unit to the maximum transmittable torque determined in the determining step when an instability occurs.
