Abstract

A method for influencing the creep torque of a motor vehicle during a standstill of the motor vehicle, - in which it is checked whether the motor vehicle is at a standstill - in case of a standstill, braking torque independent of a driver is built up by its service brake system or parking brake system, and - after completion of construction of the braking force, the creeping torque is reduced or decomposed.

Description

For affecting the method for the wriggling moment of automobile during vehicle stationary state
Background technology
Known automatic catch change-speed box or dual-clutch transmission can produce moment of creeping (Wandlermoment) or wriggling moment, to provide more comfortable to chaufeur, are specially, and vehicle does not fall to take turns on light and slow up gradient.
Produce and thisly to creep or wriggling moment needs energy, this is embodied in fuel of internal combustion engine consumption and increases or electronlmobil or the maximum of hybrid vehicle can shorten by continual mileage.
Summary of the invention
The present invention relates to a kind of method of the wriggling moment for affecting automobile during vehicle stationary state, wherein,
-check whether automobile particularly remains static when engine running or preparation travel;
-set up the lock torque independent of chaufeur when quiescence by its service braking system or emergency brake system;
-reduce after setting up braking force or reduce wriggling moment.
Can realize energy-conservation thus when automobile works.At this, by change-speed box, particularly automatic catch change-speed box or dual-clutch transmission produce or are produced by electrical motor unimportant wriggling moment.
The feature of a kind of expedients of the present invention is, after the starting hope detecting automobile driver, reduces braking force independent of chaufeur, and again improves wriggling moment.The driving sensation of custom is produced again thus to chaufeur.
The feature of a kind of expedients of the present invention is, will start hope detection for existing when chaufeur touches travel board.
The feature of a kind of expedients of the present invention is, vehicle is a kind of transmission vehicle, and it is with automatic catch change-speed box or dual-clutch transmission, and wriggling moment is provided by change-speed box.
A kind of device is also contained in the present invention, and it has the mechanism being designed to specially implement method of the present invention.Described mechanism especially controller, stores the program code for implementing method of the present invention in this controller.
Accompanying drawing explanation
Accompanying drawing comprises Fig. 1.
Fig. 1 illustrates the principle process of a kind of design of method of the present invention.
Detailed description of the invention
Utilize running brake or automatic parking brake automatically to make vehicle parking, under static state can reduce creeping or the energy consumption of wriggling moment for generation of change-speed box thus.Even if electronlmobil also often specifies there is wriggling moment, for improving the driver comfort of chaufeur, the generation of this wriggling moment and maintenance involve energy consumption and improve.
Figure 1 illustrates the flow process of a kind of design of method of the present invention.In the method after square frame 100 starts, in square frame 101, inquire whether vehicle remains static.If situation is really not so, just transfer back to the entrance of square frame 101.If but situation is like this, that just requires such as to take brake regulation by driving dynamics control system or emergency brake system independent of chaufeur subsequently in square frame 102.Next in square frame 103, inquire whether the brake system activated in square frame 102 exists initiatively (positiv) feedback.This feedback especially feedback signal, its circular has touched drg.If there is no this feedback, just transfers back to the entrance of square frame 101.If but there is this feedback, and that is, independent of chaufeur by car brakeing, that creeping or the deexcitation of wriggling moment just by automobile in square frame 104.The starting hope that whether there is chaufeur is inquired in square frame 105.If situation is really not so, just transfer back to the entrance of square frame 105.If but there is starting hope, this would be such as identified because of chaufeur shake-up travel board, and that just cancels the brake regulation independent of chaufeur of square frame 102 subsequently in square frame 106, again activates creeping or wriggling moment of automobile simultaneously.The method terminates in square frame 107.
