Description
Technical field
The present invention relates to technical field of automobile control more particularly to a kind of vehicle control systems.
Background technology
In current vehicle control system, based on being sent between control device and mancarried device in the vehicle mounted
The control of vehicle fitting is performed with the radio signal of reception, such as the locking and unlock of door are carried by user.Control is set
The standby communication means between portable device is roughly divided into three kinds of methods, such as polling method, is additionally related to multi-functional passive entry method and without key
Spoon access method.
In polling method, control device sends response request signal with the predetermined cycle, but regardless of mancarried device
How is position.If receiving response request signal, portable device is to control device returning response signal.It is being additionally related to multi-functional passive entry
In method, when user is close to door handle or when being contacted with door handle, passive request switch is opened, and control device is to portable
Device sends response request signal.If receiving response request signal, portable device is believed to control device returning response
Number.In keyless entry method, response request signal is sent not from control device to mancarried device, and works as user's operation
During mancarried device, remote signal is sent to control device from mancarried device.Under any circumstance, if from portable dress
It puts and receives response signal or remote signal, then control device performs the verification included between ID codes in the signal.It is if whole
It manages successfully, then the door of control device locking or unlock vehicle.
Control device sets oriented portable device to send the vehicle transmitting element of response request signal and from portable
Equipment receives the vehicle receiving unit of response signal or remote signal.For example, as disclosed in JP-A-2009-144367
, in the multiple vehicles of vehicle transmission unit setting inside the vehicle or on the outer surface of vehicle.Vehicle receiving unit can be single
Solely it is arranged on the vehicle interior of vehicle.Switch for vehicle device is provided on the outer surface of the car door of vehicle, such as enters and opens
It closes.
In JP-A-2009-144367, in order to enable from vehicle transmitting element send response request signal easily by position
In vehicle periphery mancarried device receive, but regardless of vehicle transmitting element position how, send intensity according to operated
Access switch come switch from vehicle transmitting element send response request signal.Specifically, near vehicle transmission unit
Access switch by operation in the case of, from vehicle transmission unit transmit response request signal intensity transmission it is relatively low.It is grasping
In the case of making access switch separated with vehicle transmission unit, the transmission of the response request signal transmitted from vehicle transmission unit
Intensity is high.
Meanwhile in polling method or in the case of being additionally related to multi-functional passive entry method, for example, illegal communication behavior can be performed, wherein
The portable device of distant place imitates state close to vehicle as relaying the result is that the response that relaying is sent from control device is asked
Signal is sought, and portable device receives response request signal.It is known as relay attack using the illegal communication behavior of relaying.No
It is that the third party of the malice of car owner can implement to steal the criminals such as vehicle by opening car door or starting engine by relay attack
Crime is.
Thus, for example, in JP-A-2010-121297, countermeasure of crime is prevented on for relay attack, based on sound
The electric field strength answered calculates the distance between vehicle transmitting element and mancarried device request signal, and based on by vehicle
The electric field strength for the response signal that receiving unit receives calculates the distance between portable device and vehicle receiving unit.
Between two distances there are sizable difference in the case of, car door is not unlocked.
In JP-A-2010-121297, with the distance calculated between vehicle transmission unit and portable device compared with
Short, portable device reduces the intensity transmission of response signal.As noted previously, as the response signal from portable device
Transmission strength reduction, even if performing relay attack, the signal that is sent from the portable device away from vehicle is not also controlled to be set up
It is standby to receive, therefore car door is not switched on.
If the intensity transmission of the response signal from portable device is low, relay attack can be prevented, but then,
Reduce the communication performance between the portable device and control device of validated user carrying.Specifically, it is being additionally related to multi-functional passive entry
When, for example, in the case of the vehicle switching device being located in validated user operation at the position separated with vehicle receiving unit, from
The transmission intensity for the response signal that the mancarried device that user carries is sent is low, therefore worries that response signal may not be by vehicle
Receiving unit receives.In this case, car door is not unlocked, and the convenience being additionally related to multi-functional passive entry disappears.
