Problems solved by technology

[0003] An inherent dilemma in conventional ESC (Electronic Stability Control) systems is the fact that the driver expects them to be aggressive in critical situations and thus have a noticeable effect on the vehicle's motion, but, on the other hand, if The ESC system intervenes in a situation he can, or at least believes he can handle himself, and the driver tends to get bored
In order for the ESC system to work as intrusively as possible, its activation threshold would have to be set rather high, thus leading the driver into a problematic situation in which harsh measurements of the ESC system are necessary, which would otherwise may be easily prevented with a lower activation threshold

Embodiment Construction

[0037] 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 circuitry. The description of the invention in terms of circuit blocks or in terms of individual features of method steps is therefore not dictated by technical necessity but merely by the fact that, in the case of simultaneous execution of the programs or the temporal relationship of the programs does not affect the invention, by structural The description of a diagram is clearer than that of a flow chart, whereas the description of a method step by a flow chart is clearer if the steps can be organized concisely in chronological order.

[0038] figure 1 is a block diagram of an apparatus for implementing the present invention. The device contains multiple sensors, all o...

Abstract

A method for assisting the driver of a motor vehicle, comprises the steps of: a) estimating a maximum safe amount of lateral acceleration based on one or more of detected vehicle lateral acceleration,yaw rate, vehicle longitudinal speed and steering wheel angle, b) calculating a longitudinal vehicle speed to produce a lateral acceleration equal to said maximum safe amount, and c) displaying a recommended longitudinal vehicle speed to the driver.

Description

technical field [0001] The invention relates to a method of assisting a motor vehicle driver in order to improve driving safety in potentially adverse 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, that is, the deviation between a desired yaw rate based on vehicle speed and steering wheel angle, and an observed yaw rate, and to assist steering Braking is applied to the wheels on one side of the vehicle individually, ie the deviation between the desired and observed yaw rates is reduced. [0003] An inherent dilemma in conventional ESC (Electronic Stability Control) systems is the fact that the driver expects them to be aggressive in critical situations and thus have a noticeable effect on the vehicle's motion, but, on the other hand, if The ESC system intervenes in ...
