Abstract
The invention relates to a novel vehicle starting method and a novel vehicle starting device, which can confirm to start an engine by identifying whether a legal key is in the vehicle. The technical scheme comprises the following steps that: a master control unit transmits a low frequency request signal to an intelligent key after a starting button is pressed down; the intelligent key transmits a high frequency feedback signal to the master control unit; and the master control unit identifies the intelligent key and transmits a starting signal to an engine control unit to start the vehicle when identifying that the legal key is in the vehicle.
Description
Technical field
The present invention relates to a kind of novel vehicle starting method and device.
Background technology
In the prior art, the vehicle launch method has two kinds, a kind of is that traditional rotating machinery key starts, promptly by the mechanical key that the driver is entrained on one's body, get final product ato unit after inserting the lockhole rotation, this start mode complicated operation lacks novelty and hommization, and mechanical key is more prone to destroyed and steals simultaneously; Another kind is that no key starts, need to arrange the existence that the key slot comes the detected electrons key, after key inserts in the slot, be arranged in slot coil all around by carrying out key identification with key inside chip inductive coupling, after the identification key is qualified, pressing start button can pilot engine, and this starting method is higher to the status requirement of key, can not satisfy the purpose that real no key starts.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of novel vehicle starting method, can whether confirm ato unit in car by the identification legal key.
The present invention is based on same inventive concept, have two independently technical schemes:
1, a kind of novel vehicle starting method, it is characterized in that: press start button, main control unit sends the low frequency request signal to sending Intelligent key, Intelligent key sends the high frequency feedback signal to main control unit, main control unit is discerned Intelligent key, when the identification legal key was in car, main control unit sent enabling signal to control unit of engine, starts vehicle.
Be provided with low-frequency antenna in the car, main control unit sends the low frequency request signal by low-frequency antenna to Intelligent key.
The working range of low-frequency antenna is 1.5 meters, thereby confirms that Intelligent key is whether in car.
Main control unit is the low frequency wireless signal with rolling code to the low frequency request signal that Intelligent key sends, and after Intelligent key received request signal, the high frequency feedback signal of transmission was to have the high-frequency wireless signals of encrypting rolling code.
Main control unit also is connected to emergency antenna, and when Intelligent key did not have electricity, emergency antenna can charge to Intelligent key.
2, a kind of realization novel vehicle starting method device, comprise control unit of engine, it is characterized in that: starting switch connects main control unit, and main control unit connects the low-frequency antenna that sends request signal to Intelligent key, and main control unit is connected with the control unit of engine communication.
Main control unit connects the emergency antenna that can charge to Intelligent key.
The beneficial effect that the present invention has:
The present invention discerns Intelligent key by main control unit, when the identification legal key is in car, presses start button and can start vehicle, starts the restriction that vehicle is not subjected to the key placement location, more user-friendly design; The communication modes of main control unit and Intelligent key adopts rolling code to encrypt, and makes the safety that has more increased vehicle; Simultaneously, when Intelligent key does not have electricity, can charge by emergency antenna, the feasible Intelligent key startup vehicle that utilizes is convenient.
Description of drawings
Accompanying drawing is the schematic block circuit diagram of vehicle starting device of the present invention.
The specific embodiment
As shown in the figure, starting switch connects main control unit, and main control unit connects the low-frequency antenna that sends request signal to Intelligent key, and main control unit is connected with the control unit of engine communication, and main control unit connects the emergency antenna that can charge to Intelligent key.Low-frequency antenna can be provided with three, is positioned at the diverse location of car, and emergency antenna can be arranged on two side positions in the car, and the working range of emergency antenna is 3 meters.Main control unit comprises MCU, low frequencies device, high-frequency receiver, communication is connected this MCU with the high-frequency receiver difference with the low frequencies device, Intelligent key comprises three-dimensional low-frequency antenna receiver, HF transmitter, MCU, and communication is connected this MCU with HF transmitter with the three-dimensional low-frequency antenna receiver.
When starting vehicle, press start button, main control unit sends the low frequency request signal by low-frequency antenna to Intelligent key, this low frequency request signal is the low frequency wireless signal with rolling code, this request signal makes Intelligent key produce induced-current, trigger Intelligent key and send the high frequency feedback signal to main control unit, the high frequency feedback signal is to have the high-frequency wireless signals of encrypting rolling code, main control unit is discerned Intelligent key, when the identification legal key is in car, main control unit sends enabling signal to control unit of engine, starts vehicle.Wherein, the working range of low-frequency antenna is 1.5 meters, thereby confirms that Intelligent key is whether in car.When Intelligent key did not have electricity, emergency antenna can charge to Intelligent key, thus the startup of more convenient and smart key.
Not have key or key in the car be illegal key if detect, and then automobile can not start, and shows " not detecting key " or information such as " key are illegal " on the instrument display screen being presented at simultaneously.If after the engine start, key leaves the startup active region, and then motor is flame-out, but can't carry out starting next time, and the while shows on instrument " do not detect key " information.
For increasing the safety of automobile starting, main control unit sends enabling signal to control unit of engine and starts the condition of vehicle except that having aforesaid start button, the identification legal key pressed inside and outside car, also the condition that need have for step on foot rest, shift bar is in " P " or " N " gear, electronic steering lock can normal releases, in addition, but system is the integrated engine anti-theft feature also, and main control unit carries out antitheft communication by CAN and control unit of engine.
