Abstract

A system for combined automatic and manual control of the motion of a vehicle comprises at least one manual control device and automatic equipment with at least one executing device. The executing device is coupled to the manual control device in such a way that a counterforce is generated in the manual control device to the force supplied by the driver. This counterforce is a function of the deviation, produced by the driver, from the intention of the automatic equipment. The automatic equipment is such that, over the whole control range, this counterforce is less than the force that the driver is able to apply on the manual control.
