CONTROL DEVICE FOR IMPROVING THE TRACTION OF A VEHICLE
First Claim
1. A vehicle control device, in particular for a motor vehicle with two drive wheels, rolling on roads or terrains, intended to define engine torque and wheel braking instructions for the vehicle, comprising:
- means for generating different control modes as a function of parameters concerning the way in which the vehicle is moving, such as rotational speed of the wheels, yaw rate, lateral acceleration and longitudinal acceleration, pressure on the brake controls exerted by the driver, and a vehicle life situation mode chosen by the driver from various pre-established life situations corresponding to different types of roads and terrains and different vehicle rolling conditions,estimating means for estimating the vehicle life situation, the device being configured to determine an optimum control mode from among the various control modes that can be generated by the device as a function of the estimated vehicle life situation and the life situation mode chosen by the driver, characterized in that the means for estimating the vehicle life situation comprise a recognition logic of the type of roads or terrains confirming or not confirming the life situation mode chosen by the driver.

Abstract
The invention relates to a vehicle control device comprising: —means (10, 20, 30) for generating various control modes dependent on parameters concerned with the way in which the vehicle is moving such as, rotational speed of the wheels, yaw rate, lateral acceleration and longitudinal acceleration, pressure on the brake controls exerted by the driver, and a vehicle life situation mode chosen by the driver from various preestablished life situations corresponding to different types of road and terrain and different vehicle rolling conditions, —estimating means (40) for estimating the vehicle life situation, the device being configured to determine an optimum control mode (32, 34, 36, 38) from among the various control modes that can be generated by the device as a function of the estimated vehicle life situation and the life situation mode chosen by the driver.
