Detailed description of the invention
The present invention proposes a kind of Driving assistant system 100, as it is shown in figure 1, this system 100 includes for detecting vehicle
The spacing (including horizontal spacing) of (this car) and surrounding objects (including traffic participant such as vehicle, pedestrian etc., or barrier)
Spacing testing agency and controller.Spacing testing agency such as includes at least one spacing sensor.Spacing sensor example
As can be range radar sensor, laser range sensor, infrared distance measuring sensor, ultrasonic distance-measuring sensor and/or
Vision sensor etc..Spacing testing agency can also include video camera or similar image forming device, exists in order to verify vehicle
Position in traffic route and state.
The distance that " spacing " is not limited solely between car and car herein, but also include Ben Che and surrounding object
Or the distance between pedestrian.Therefore, the data that spacing testing agency is detected reflect vehicle working as in traffic route substantially
Front position and its residing transport condition.
Additionally, it should be noted that the term " vehicle " in the present invention may refer to any suitable walking-replacing tool, it include but not
It is limited to two wheeler, tricycle and carriage, such as, can be electric motor car with two wheels, three-wheeled electric vehicle, car, truck and bus
Etc..
This controller is configurable to detection data based on spacing testing agency and judges that whether spacing is in predetermined critical
(or being referred to as dangerous marginal value) below, and assigns operation vehicle instruction, in order to pull open car when spacing is below predetermined critical
Away from.Instruction such as can be selected from left steering instruction, right turn instruction, assisted instruction, deceleration instruction and braking instruction.
Preferably, spacing testing agency is included in the car device for detecting distance on lateral direction of car at least side or may also include
Car device for detecting distance on vehicle front side and/or rear side.Preferably, in the present embodiment, spacing testing agency is at vehicle
Both lateral sides is provided with car device for detecting distance, i.e. at the first car device for detecting distance of lateral direction of car side with at horizontal opposite side
On the second car device for detecting distance.Preferably, controller is further configured to the detection data when the first car device for detecting distance
Time below predetermined critical, the detection data according to the second car device for detecting distance are optionally assigned towards described horizontal opposite side
Steering order, braking instruction, deceleration instruction or the assisted instruction turned to, vice versa.
Preferably, controller is further configured to when the detection data of the second car device for detecting distance turn in minimum safe
The steering order turned to towards described horizontal opposite side can be assigned time more than marginal value.Or, under the most also may select
Reach assisted instruction, deceleration instruction or braking instruction, as long as the distance between surrounding vehicles can be pulled open safely.
Preferably, controller is further configured to when the detection data of the first and second car device for detecting distance are all predetermined
Braking instruction, deceleration instruction or assisted instruction is optionally assigned time below marginal value.
As illustrated in fig. 1 and 2, at one preferably but in not limiting example, described horizontal side be left side and described laterally
Opposite side is right side.In such cases, this spacing left side vehicle is shown when the detection data of the first spacing testing agency
Distance reaches below predetermined critical, and when i.e. exceeding risk distance, now, controller can be by this detected car and right car
Lateral separation decide whether to adjust to the right travel direction.Now, the distance between Ruo Benche and right side vehicle is the most real
Now safety is when turning to (i.e. turning to more than marginal value in minimum safe), controller can such as assign right turn instruction pull open its with
Distance between left car, vice versa.And correspondingly, may select when left and right sides spacing is all below predetermined critical and assign
Assisted instruction, deceleration instruction or braking instruction.Therefore, the system 100 of the present embodiment can dynamically balance this car both sides and week
The distance of limit object, it is ensured that traffic safety, drives more comfortable.
Supplementing optionally or as such scheme, it is preferable that as illustrated in fig. 1 and 2, described system
100 may also include spacing alert mechanism.Preferably, spacing alert mechanism may be included in the spacing of vehicle left side in predetermined critical
The first warning devices sending alarm time following and the send alarm when the spacing on right side is below predetermined critical second police
Reporting device.In some object lessons, spacing alert mechanism such as can include audio alarm and/or light warning devices.Car
Such as can include LED and/or speaker away from alert mechanism, thus when generating the alarm, LED flashes to remind driver
With other vehicle, and speaker energy sounding is reminded.It is contemplated that in the case, except by the automatic control of controller
System, driver is also optional according to the spacing of detected both lateral sides or manually to be adjusted according to the alarm of spacing alert mechanism
The travel direction of joint vehicle or speed, or notably select brake hard.
Preferably, as it is shown in figure 1, Driving assistant system 100 may also include the side for regulating vehicle heading
To governor motion, in this case, controller can be further configured to the first warning devices or the second warning devices is sent out
Responding is given the correct time and is sent left steering instruction or right turn instruction.Additionally, controller can be further configured to when first and second is alert
When reporting device all sends alarm and/or the first and second car device for detecting distance detection data all below predetermined critical at present
Reach assisted instruction, deceleration instruction or braking instruction to control power adjustment mechanism to regulate speed or braking.
Therefore, as in figure 2 it is shown, traffic safety auxiliary can so be performed, i.e. first pass through spacing testing agency detection car
With the spacing 201 of surrounding objects, afterwards, controller detection based on spacing testing agency data judge that whether spacing is predetermined
Below marginal value 202, when the detection data of left side the first car device for detecting distance are below predetermined critical and the second spacing of right side
The steering order towards right hand steering assigned by detection data controller when minimum safe turns to more than marginal value of detection device
203；When the detection data of the first and second car device for detecting distance are all below predetermined critical, controller is optionally assigned
Braking instruction, deceleration instruction or assisted instruction 204；Or or additionally, when first or second or first and second spacings examine
When the detection data of survey device are below predetermined critical, controller correspondingly controls the first or second or first and second polices
Reporting device sends alarm 205.
Preferably, as it is shown in figure 1, Driving assistant system 100 may also include the power adjustment machine for regulating power
Structure, wherein, controller is further configured to detect when the first and second warning devicess all send alarm and/or according to spacing
The detection data of mechanism assign assisted instruction, deceleration instruction or braking instruction, to control power adjustment mechanism regulation speed or system
Dynamic.
Preferably, under power adjustment mechanism may be included in the control of controller by change automobile driving force size and/
Or interruption driving force realizes the vehicular propulsion of car deceleration and brake hard, it such as can be realized by such mode:
