Control method for an automated gearbox of an automotive vehicle, system for controlling such a gearbox and automotive vehicle equipped with such a system
First Claim
1. A control method for an automated gearbox of an automotive vehicle, the gearbox being adapted to work in:
- a first automatic modeat least one second driver initiated mode which is different from the first mode wherein the method includes at least the following steps;
a) monitoring the vehicle driving behaviour,b) analyzing the vehicle driving behaviour and determining if the driving behavior is below a first limit value or a second limit value, wherein a first alarm message is sent to the driver below the first limit value, and wherein the vehicle driving behavior is determined to be satisfactory above the second limit value and non-satisfactory below the second limit value, andc) at least one ofi) when the driver requests switch of the automated gearbox from the first mode to the second mode, following the switch order only if, in step b), the vehicle driving behaviour is determined to be satisfactory, andii) when the automated gearbox is in the second driver initiated mode, causing a switch of the gearbox to the first automatic mode if, in step b), the vehicle driving behaviour is determined to be non-satisfactory.

Abstract
A method is provided for controlling an automated gearbox of an automotive vehicle that is adapted to work in a first automatic mode and at least one second driver initiated mode which is different from the first mode. This method includes monitoring the vehicle driving behavior is monitored, analyzing the vehicle driving behavior is and determining it to be satisfactory or non satisfactory and, when the driver requests switch of the automatic gearbox from the first mode to the second mode, the switch order is followed only if the vehicle driving behavior is determined to be satisfactory, and/or, when the automated gearbox is in a second driver initiated mode, causing a switch of the gearbox to a first automatic mode if the vehicle driving behavior is determined to be non-satisfactory. The system includes an arrangement to automatically perform these steps.

10. A system for controlling an automated gearbox of an automotive vehicle, the gearbox being adapted to work in:
-
a first automatic mode, at least one second driver initiated mode which is different from the first mode wherein the system includes, first means to automatically monitor the vehicle driving behaviour, second means to automatically assess whether or not the vehicle driving behaviour is satisfactory, and third means to at least one of i) automatically and selectively block an order to switch the automated gearbox from its first mode to its second mode, wherein the order is automatically and selectively blocked for at least one of a period of time and for a distance, and ii) to automatically and selectively switch back the gearbox from the second mode to the first mode, on the basis of an output of the second means. - View Dependent Claims (11, 12, 13, 14, 15)
