Said first judging unit 120 is judged the current neutral state that whether is in of said vehicle according to said real-time gear information, exports the said first judgement information.
Said gear position sensor 110 can adopt mechanical type or electronic type, and its installation site can be arranged on the gearshift (like gear shifting handle) of vehicle, as long as there is the gear shift action to produce, gear position sensor 110 is the residing gear of ability perception just, and the output real-time gear information.
Said car speed sensor 130 is used for the speed condition of the said vehicle of perception, output real-time speed information.
Said second judging unit 140 is used for judging that according to said real-time speed information the current speed of said vehicle whether greater than first threshold, exports the second judgement information.
Said first threshold can be an arbitrary value according to actual conditions and requirements set, and as 5 kilometers/hour, 10 kilometers/hour, 20 kilometers/hour etc., the present invention does not limit this.
Said processing unit 150 is used for said first judgement information and the said second judgement information are carried out logical process, and generates final output information as a result according to the logical process result.
Wherein, Said logical process can be that logical AND is handled; Also can be logical OR processing or other processing mode; Various embodiments of the present invention are preferably logical AND and handle; Said first judges information representation for being or not, and said second judges information representation for being or denying, therefore; Output information as a result after the logical process possibly also possibly be vacation for very.Under the situation that logical AND is handled; Has only the first judgement information and the second judgement information all when being; Output information as a result after the logical process just can be true; Other all be false; Under the situation that logical OR is handled, when having one in the first judgement information and the second judgement information when being, the output information as a result after the logical process is very; Having only the first judgement information and the second judgement information all is not the time, and the output information as a result after the logical process just can be false.
The function of said processing unit 1 50 can realize that the function that separate processor is accomplished said processing unit 150 can certainly be set, and the present invention does not limit this through the ECU (vehicle-mounted computer) in the vehicle.
Said Tip element 160 is used for generating the corresponding prompt warning message according to said output information as a result.
When said output information as a result is true time, said Tip element is given birth to 160 one-tenths and is pointed out warning messages, and said prompting warning message can be presented at through the form of literal or pattern on the read-out of gauge panel, also can realize with sound or other mode.Said prompting warning message can be some tell-tale language, literal or pattern, as: " being that neutral gear slides danger now ", " forbidding that neutral gear slides ", " asking gear shift " ...
Slide among another embodiment of prompt system 100 at a kind of neutral gear of the present invention, said neutral gear slides prompt system and also comprises:
The 3rd judging unit (figure do not show) is used for when the said vehicle of the said first judgement information representation is current when being in neutral state, judges that duration that said vehicle is in neutral state whether greater than second threshold value, produces the 3rd judgement information.
Said second threshold value can be according to actual conditions and requirements set, and the present invention does not limit this, as being 10s, 15s, 20s or other time span.
In the present embodiment, 150 pairs of said first judgement information of said processing unit, the said second judgement information and said the 3rd judgement information are carried out logical process, and generate final output information as a result according to the logical process result.
In another embodiment, said neutral gear slides prompt system 100 and also comprises:
Brake gear (figure does not show), being used for working as said output information as a result is true time, and said vehicle is carried out brake.
Through the technical scheme of present embodiment, when vehicle was in the neutral gear sliding state, vehicle can automatically perform brake, thereby stoped chaufeur to carry out the neutral gear slide action, had improved traffic safety.
In addition, said neutral gear slides prompt system 100 and can also comprise:
Record cell (figure do not show) is used to write down the gear information and the velocity information of said vehicle.
Transmitting element (figure does not show) is used for through global position system GPS said gear information and said velocity information being sent to remote enquiry system.
Through the setting of said record cell and said transmitting element, can long-range realization to the inquiry of vehicle running state, convenient to management of vehicles with to the grasp of motoring condition.
Technical scheme of the present invention is through the comprehensive judgement to range state and speed state, and correspondence is sent the prompting warning message, thereby can remind chaufeur to prevent to slide automatically; Further, when vehicle is in neutral gear sliding state and speed and surpasses pre-set velocity, carry out brake, thereby can prevent sliding automatically of vehicle by actv., improved traffic safety through brake gear.
In addition; The invention also discloses a kind of vehicle; Said vehicle comprises like the described neutral gear of preceding each embodiment and slides prompt system 100; Because each embodiment of front slides prompt system 100 to said neutral gear and describes in detail and introduce; For length is considered; Repeat no more at this, get final product with reference to the description of front relevant portion.
In addition, the invention also discloses a kind of neutral gear and slide reminding method.Comprise:
Step S210, judge the current neutral state that whether is in of said vehicle, export the first judgement information, get into step S240.
