Description
Technical field
The present invention relates to a kind of method and apparatus for triggering safety device.
Background technology
By the method and apparatus for triggering safety device known in the art, the safety device can be in vehicle accident
Impact is produced on vehicle in the case of slip.
Such a safety device is for example disclosed in DE102008007940B4, it is applied to the slip of detection vehicle
And close the dynamical system of service brake or automatically controlled parking brake or vehicle when necessary.
The content of the invention
The starting point of the present invention is can to provide a kind of method for triggering safety device, and the safety device is in vehicle
Impact is produced on vehicle in the case of unexpected slip.
The core of the present invention is acquisition at least one for representing the motion conditions of at least one wheel of the vehicle
Variable, and the steering mechanism of vehicle is at least triggered according to the variable.According to the present invention, in addition to triggering steering mechanism, moreover it is possible to
Enough closing other contributes to the actuator of safety, such as parking brake and/or service brake and/or other brakings
Actuator and/or dynamical system and/or hang up transmission range and/or notify and warn vehicle driver or other people and/
Or in the framework internal transmission information of vehicle-to-vehicle communication.
The background of the present invention is, such as because the failure of parking brake will cause vehicle that unexpected slip occurs.If
There is such case, then be desirable to other safety devices, particularly only set when the unexpected in the case of of sliding for vehicle
Having put when tense again parking brake and the parking brake simultaneously because its failure and result in unexpected slip.
By way of the steering mechanism as safety device is used according to demand, it is unnecessary for touching not only to avoid
The components of stress of steering mechanism are sent out, and avoids the occurrence of unnecessary tire wear.
A favourable design of the invention, is adjusted to relative by triggering steering mechanism by the wheel of vehicle
In the vertical axis tilt of vehicle.
Here, the wheel can be adjusted to that relative to longitudinal axis same direction or rightabout.
The unidirectional relative inclination of the wheel can result in the change of vehicle glide direction.
Situation unidirectional relative to the longitudinal axis is adjusted to based on by the wheel, the unexpected vehicle for sliding will be occurred and adjusted
It is whole to the position tilted with original glide direction.
Rightabout relative inclination can result in vehicle and directly stop.
Preferably, the orientation of the obliquity of the wheel is adjusted according to the environmental assessment obtained by sensing mode.Its
In, the sensor for environmental assessment is preferably photographing unit and/or radar and/or sonac.
The background of environmental assessment is to make vehicle point to road side when necessary by the obliquity of the wheel
Edge, and determine steering direction further according to barrier (such as other vehicles, lane markings line, pedestrian).
In other favourable designs of the present invention, obtained by means of at least one motion sensor and represent the car
At least one wheel motion variable.
Preferably, steering mechanism electricity ground or hydraulically or pneumatically drive.
Preferably, motion sensor is associated respectively with the wheel being arranged on axle, and is triggered in the way of wheel or axle
The steering mechanism.
According to a favourable design, at least one car for representing the vehicle is obtained on the fixed persistent period
The variable of the motion of wheel, wherein it is preferred to, according to the temperature of the parking brake of the inclination and/or the expression vehicle of vehicle
Second variable of value, particularly brake backing plate temperature are determining persistent period of the fixation.
The background of the favourable design is that vehicle occurs the unexpected probability for sliding will diminish over time.
The acquisition is the inclination that the persistent period of necessary period depends on the vehicle and/or the parking brake for representing vehicle
Second variable of temperature value (particularly brake backing plate temperature).Selecting the persistent period of the fixation of the acquisition will cause described
The load of the vehicle electronic circuit of vehicle reduces.
A favourable design of the invention, according to the motion of at least one wheel for representing the vehicle
At least one variable triggers the steering mechanism.Here, especially arrange, according to the comparison of the variable and at least one threshold value
Come trigger the steering mechanism and/or the variable exceed the threshold value when trigger the steering mechanism.
Preferably, in the case where the vehicle occurs unexpected slip using adjusting means or control device, so that described
Safety device runs to exert one's influence.Here, obtaining the change of the motion of at least one at least one wheel for representing the vehicle
Amount, wherein, the steering mechanism of the vehicle is at least triggered according to the variable of the motion of at least one wheel for representing the vehicle
As safety device.
Dependent claims provide other designs of the present invention.
Description of the drawings
Hereafter the present invention, but this will be illustrated by means of the embodiment of the creative feature of the others that can provide the present invention
Invention is not limited in the scope of embodiments.To following figures illustrate the present invention.Wherein：
Fig. 1 shows the schematic flow chart for triggering safety device method and step.
Specific embodiment
Fig. 1 shows the flow chart for triggering the method and step of safety device.Triggering peace is introduced by method and step 11
The process of full device.In method and step 22, by means of the rotary motion of at least one wheel of sensor check vehicle.If
It is determined that without rotary motion, then the process of end trigger safety device in method and step 44.If in method and step 22
It is determined that there is rotary motion, then trigger the steering mechanism of vehicle according to the variable of at least one wheel movement for representing vehicle.Should
Triggering occurs in method and step 33.After triggering steering mechanism, the rotary motion of at least one wheel of vehicle is checked again.Such as
Fruit is determined without rotary motion, then the end trigger process in method and step 44, otherwise performs the step of triggering steering mechanism
And till checking the rotary motion until no longer rotating motion.
