Problems solved by technology

[0003] The inherent dilemma in conventional ESC systems is the fact that the driver expects them to be active and reliable in critical situations, thus having a noticeable effect on the movement of the vehicle, but, on the other hand, if the ESC system is useful to him- Or at least intervene in a situation he believes he can handle himself, and the driver tends to become bored
In order for the ESC system to be as intrusive as possible, its activation threshold would have to be set rather high, thus leading the driver into a problematic situation where harsh measurements of the ESC system are necessary, which This situation could have been easily prevented by using a lower activation threshold

Embodiment Construction

[0025] For the following description to be properly understood, it should be borne in mind that the invention will most likely be implemented in the form of a suitably programmed microcontroller system, but functions running as software in such a microcontroller system may equally well be implemented by wired circuits. Therefore, the description of the invention in terms of circuit blocks or in terms of individual features of method steps is not dictated by technical necessity but simply by the fact that simultaneously performed processes or the temporal relationship of processes do not affect the invention , the description by means of a block diagram is easier to understand than by a flow chart, whereas the description of a method step by means of a flow chart is clearer if the steps can be concisely organized in chronological order.

[0026] figure 1 is a block diagram of an apparatus for implementing the invention. The device contains a number of sensors, all of which are...

Abstract

A method for assisting a driver of a motor vehicle comprises the steps of a) monitoring at least one quantity selected among vehicle sideslip, yaw rate error, understeer and quantities correlated to vehicle sideslip, yaw rate error or understeer, b) deciding that there is a risk of the vehicle becoming unstable if any of said monitored quantities or a quantity derived (S3, S5, S6) from one or more of said monitored quantities exceeds a predetermined first threshold (S9); and c) if it is decided that there is a risk, issuing a warning signal (S10).

Description

technical field [0001] The invention relates to a method of assisting a driver of a motor vehicle to improve driving safety in potentially dangerous road conditions. Background technique [0002] Electronic stability control systems for motor vehicles have become increasingly popular in recent years. Traditionally, such systems monitor quantities related to vehicle stability, such as yaw rate deviation (i.e., the deviation between a desired yaw rate based on vehicle speed and steering wheel angle, and an observed yaw rate), and in order to assist cornering Cornering applies brakes to the wheels on one side of the vehicle separately, ie to reduce the deviation between the desired and observed yaw rates. [0003] The inherent dilemma in conventional ESC systems is the fact that the driver expects them to be active and reliable in critical situations, thus having a noticeable effect on the movement of the vehicle, but, on the other hand, if the ESC system is useful to him- Or...
