The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
By background technology as can be known, existing automobile engine starting system starts in the process of automotive engine, all need key is inserted Steering gear, and necessary manual rotation key, because the user is difficult to accurately control rotational time, make the startup of driving engine be affected, the convenience and the user that greatly reduce start the engine experience.
The utility model embodiment discloses a kind of engine starting system.This engine starting system comprises that key, inside that driving engine start and stop button, inside are provided with signal transceiver are provided with the key slot of steering shaft unlock switch, antitheft coil and the first controller.When key inserts the key slot, but need not screw key with regard to the release steering shaft and generate on-off signal, the first controller receiving key signal, and by antitheft coil and key wireless connections, key is authenticated, after authentication is passed through, triggering starts the start and stop button to generate the first energizing signal, the first controller receives the first energizing signal, and generates Engine Start Signal, and control engine starts.Whole process need not screw key, and the cooperation by steering shaft unlock switch, antitheft coil, the first controller and driving engine start and stop button is light start the engine just, and the convenience and the user that have improved start the engine experience.The concrete structure of above-mentioned engine starting system and principle of work will be elaborated by following examples.
Embodiment one
See also accompanying drawing 1, be the structural representation of the utility model embodiment one disclosed a kind of engine starting system.This engine starting system is comprised of driving engine start and stop button 10, key 11, key slot 12, antitheft coil 13 and the first controller 14, wherein, is provided with signal transceiver 110 in key 11, is provided with steering shaft unlock switch 120 in key slot 12.
The principle of work of above-mentioned engine starting system is specially:
User's carrying keys 11 into the car after, key 11 is inserted in key slot 12, in the process of inserting, stroke and thrust during by insertion make the steering shaft release, the key that steering shaft unlock switch 120 in while key slot 12 is inserted into triggers, and generates on-off signal and also sends to the first controller 14.after the first controller 14 receiving key signals, generate authentication request signal, and send to anti-theft wire circle 13, after antitheft coil 13 receives authentication request signal, send to the signal transceiver 110 of key 11 inside, at this moment, signal transceiver 110 in key 11 produces authentication response signal, and send to anti-theft wire circle 13, antitheft coil 13 sends to the first controller 14 with the authentication response signal that receives, the first controller 14 authenticates key 11 according to the authentication response signal that receives, after authentication is passed through, the user presses driving engine start and stop button 10 and generates the first energizing signal, after the first controller 14 receives the first energizing signal, control engine starts.
Need to prove, antitheft coil 13 is by wireless connections with the inner signal transceiver 110 that arranges of key 11.Can set in advance certain radio communication rule between antitheft coil 13 and signal transceiver 110, after treating both to satisfy the radio communication rule that sets in advance, show and both communicate by letter successfully, just can carry out follow-up verification process.That is to say, the first controller 14 can not directly send to authentication request signal key 11, must be via antitheft coil 13, send to key 11 in the mode of radio communication, signal transceiver 110 in key 11 just can receive authentication request signal, and generates corresponding authentication response signal.
Equally, the authentication response signal that key 11 produces can not directly send to the first controller 14, must via antitheft coil 13, in the mode of radio communication, send to the first controller 14.After the first controller 14 receives authentication response signal, this authentication response signal and the authentication information of presetting are compared, if this authentication response signal is consistent with default authentication information, the judgement authentication is passed through, if this authentication response signal is inconsistent with default authentication information, the judgement authentication is not passed through.
In addition, driving engine start and stop button 10 can be the button of an integral body, can be also two buttons that separate, and namely is divided into starting button and closing button.When the as a whole button of driving engine start and stop button 10, after the user presses this button, this button just generates an electric signal, is to be judged according to conditions such as engine condition, change speed gear box state, vehicle stop or mobile statuss by the first controller and this electric signal is actuation signal or closing signal.When driving engine start and stop button 10 was two buttons that separate, after the user pressed and starts button, this button produces actuation signal, and was same, and the user presses when closing button, and this button produces closing signal.
The disclosed engine starting system of the utility model embodiment one comprises that key, inside that driving engine start and stop button, inside are provided with signal transceiver are provided with the key slot of steering shaft unlock switch, antitheft coil and the first controller.When key inserts the key slot, but need not screw key with regard to the release steering shaft and generate on-off signal, the first controller receiving key signal, and by antitheft coil and key radio communication, key is authenticated, after authentication is passed through, triggering starts the start and stop button to generate the first energizing signal, the first controller receives the first energizing signal, and generates Engine Start Signal, and control engine starts.Whole process need not screw key, and the cooperation by steering shaft unlock switch, antitheft coil, the first controller and driving engine start and stop button is light start the engine just, and the convenience and the user that have improved start the engine experience.
