First Claim
1. Assistance method for performance driving of a vehicle (1);
- the assistance method comprises the following steps;
estimating the reaction time of the driver in accordance with the driving characteristics of the driver;
identifying a route (P) used by the vehicle (1);
identifying on each section of the route (P) the optimum point (Po) for the operation of an accelerator command, a brake command, a steering command and/or a gearbox command;

Abstract
An assistance method for performance driving of a vehicle; the assistance method includes the steps of: identifying a route used by the vehicle; on each section of the route, identifying the optimum point for the operation of an accelerator command, a brake command, a steering command and/or a gearbox command; identifying the current position of the vehicle along the route; identifying the next optimum point for the operation of a command; identifying a warning advance in accordance with an estimate of the reaction time of the driver and in accordance with the current speed and acceleration of the vehicle; and signalling to the driver to operate the command using the previously identified warning advance so that the driver actually operates the command at the optimum point of operation.
