Abstract
The invention relates to a method and an apparatus for controlling a safety device for influence in case of ivoluntary rolling of a vehicle, wherein, at least one variable of wheel movment for expressing vehicle is acquired, according to at least one variable of the movment of the wheel for expressing the vehicle controls at least one steering mechanism of the vehicle as saftey device.
Description
Technical field
The present invention relates to a kind of for triggering the method and apparatus of safety device.
Background technology
By prior art cicada, for triggering the method and apparatus of safety device, this safety device can exert an influence to vehicle in the situation that vehicle surprisingly slides.
For example in DE102008007940B4, disclose a kind of like this safety device, it is applicable to detect the slip of vehicle and closes where necessary service brake or automatically controlled Parking Brake or the power system of vehicle.
Summary of the invention
Departure point of the present invention is to provide a kind of for triggering the method for safety device, and described safety device exerts an influence to vehicle in the situation that vehicle surprisingly slides.
Core of the present invention is to obtain the variable of the motion conditions of at least one at least one wheel that is used for representing described vehicle, and according to described variable, at least triggers the steering hardware of vehicle.According to the present invention, except triggering steering hardware, can also contribute to the actuating unit of safety by closed other, for example Parking Brake and/or service brake and/or other brake actuator and/or power system and/or hang up speed change gear and/or notice warn chaufeur or other people and/or the framework internal transmission information to car communication at car of vehicle.
Background of the present invention is, for example, because Parking Brake malfunctioning will cause the vehicle slip that meets accident.If this occurs, so just wish other safety device, particularly in the unexpected situation of sliding for vehicle, be only provided with while again straining Parking Brake and described Parking Brake has caused unexpected slip simultaneously because it is malfunctioning.
By being used as according to demand the mode of the steering hardware of safety device, not only avoiding unnecessary for triggering the components of stress of steering hardware, and avoid occurring unnecessary wear on tyres.
According to a favourable design plan of the present invention, by triggering steering hardware, the wheel of vehicle is adjusted into the vertical axis tilt with respect to vehicle.
At this, described wheel can be adjusted to respect to the same direction of the longitudinal axis or opposite sense.
The unidirectional relative inclination of described wheel can cause the variation of vehicle direction of slip.
Based on described wheel being adjusted into respect to the unidirectional situation of the longitudinal axis, the vehicle sliding that meets accident be adjusted to the position tilting with original direction of slip.
Rightabout relative inclination can cause vehicle directly to stop.
Preferably, according to the environmental assessment of obtaining by sensing mode, regulate the orientation of the obliquity of described wheel.Wherein, the described sensor for environmental assessment is preferably photographic camera and/or radar and/or sonac.
The background of environmental assessment is, the obliquity by described wheel makes vehicle point to where necessary road edge, and for example, according to obstacle (other vehicles, lane markings line, pedestrian), determines steering direction in addition.
In other favourable design plans of the present invention, by means of at least one motion sensor, obtain the variable of the motion of at least one wheel that represents described vehicle.
Preferably, described steering hardware is electricity ground or hydraulically or pneumatically drives.
Preferably, motion sensor is associated with the wheel being arranged on axle respectively, and triggers described steering hardware in the mode of wheel or axle.
According to a favourable design plan, on fixing time length, obtain the variable of the motion of at least one wheel that represents described vehicle, wherein, preferably, according to the inclination of vehicle and/or represent that second variable, particularly brake support plate temperature of temperature value of the Parking Brake of described vehicle determine described fixing time length.
The background of described favourable design plan is, vehicle meets accident the probability that slides along with the time will diminish.At the described time length obtaining during necessary, depend on the inclination of described vehicle and/or represent second variable of temperature value (particularly brake support plate temperature) of the Parking Brake of vehicle.The fixing time length obtaining described in selection reduces the load that causes the vehicle electronic circuit of described vehicle.
According to a favourable design plan of the present invention, according at least one variable of the motion of at least one wheel of the described vehicle of expression, trigger described steering hardware.At this, relatively triggering described steering hardware and/or trigger described steering hardware when described variable surpasses described threshold value according to described variable and at least one threshold value is set especially.
Preferably, in the situation that meeting accident slip, described vehicle uses control apparatus or control setup, so that described safety device moves to exert one's influence.At this, obtain the variable of the motion of at least one at least one wheel that represents described vehicle, wherein, the steering hardware that at least triggers described vehicle according to the variable of the motion of at least one wheel of the described vehicle of expression is as safety device.
Dependent claims provides other design plan of the present invention.
Accompanying drawing explanation
Below will set forth the present invention by means of providing other the embodiment of creationary feature of the present invention, but the present invention is not confined in this scope of embodiments.With the following drawings, show the present invention.Wherein:
Fig. 1 shows for triggering the schematic diagram of circuit of safety device method step.
The specific embodiment
Fig. 1 shows for triggering the diagram of circuit of the method step of safety device.By method step 11, introduce the process that triggers safety device.In method step 22, by means of rotatablely moving of at least one wheel of sensor check vehicle.If determine and do not rotatablely move, so the process of end trigger safety device in method step 44.If define and rotatablely move, according to the variable that represents at least one wheel movement of vehicle, trigger so the steering hardware of vehicle in method step 22.This triggering occurs in method step 33.Trigger after steering hardware, again check the rotatablely moving of at least one wheel of vehicle.If determine and do not rotatablely move, end trigger process in method step 44, triggers the step of steering hardware and checks this to rotatablely move until no longer rotate motion otherwise carry out so.
