Description
Technical Field
The invention relates to the field of vehicles, in particular to a control system and a control method for a vehicle.
Background
In the related art, the functions of entering, starting and memorizing the vehicle are usually determined according to the ID number transmitted after the remote key or the smart key is pressed down. The functions of entering and starting the vehicle are realized through the legal ID of the key, and the functions of memorizing the seat position and the rearview mirror position corresponding to different keys and the like are realized through the identification of different legal IDs. And operating an unlocking or locking button on the key, transmitting the ID of the key to the vehicle-end controller through specific radio frequency by the key, and transmitting the ID to each execution module after the vehicle-end controller verifies the ID is legal.
In the vehicle control described above, the vehicle recognizes the key and does not recognize the driver for storage. For example, the owner of the vehicle uses the key 1, the wife of the owner of the vehicle uses the key 2, the positions of the seat memory and the rearview mirror memory are distinguished according to the numbers of the keys, once the owner of the vehicle carries the key 2 in a certain vehicle using process, the memory position fed back by the vehicle is the wife of the owner of the vehicle, and the vehicle is not suitable for the owner of the vehicle. Secondly, the number that every car can match legal key is limited, and this has also restricted vehicle memory function's expansibility, for example car owner's friend borrows the vehicle, no matter he takes the key of car owner's No. 1 or the key of car owner wife No. 2, the memory position of vehicle feedback can not be applicable to car owner's friend, no matter how many times of borrowing, all need manual going to adjust. If the owner's friend borrows the vehicle for a long time, the seat position and the rearview mirror position are memorized into the habit of the owner by using the borrowed key in the hands of the owner. Then the adjustment is needed again when the owner of the vehicle reuses the vehicle while he returns the vehicle. The above disadvantages are contrary to the intelligent and comfortable ideas that the memory function of the vehicle configuration wants to express, and cannot really bring intelligent, comfortable and humanized experience to the user.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Additionally, it should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
Fig. 1 shows a block diagram of a control system for a vehicle according to an embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a control system for a vehicle that may include at least a fingerprint module controller 110 and a processor 120.
The fingerprint module controller 110 may receive fingerprint image information of a user, which may be generated by an in-vehicle fingerprint recognition module or an out-vehicle fingerprint recognition module by collecting a fingerprint of the user. The fingerprint module controller 110 may perform minutiae and texture feature extraction on the received fingerprint image to generate a first fingerprint identifier.
The fingerprint module controller 110 may identify whether the fingerprint database stores the same fingerprint identifier as the generated first fingerprint identifier to generate a fingerprint identification result R. The fingerprint module controller 110 may be provided with a fingerprint library, which may be stored in, for example, an EEPROM. One or more fingerprint identifications may be pre-stored in the fingerprint repository. The user can select to add and delete the fingerprint identification stored in the fingerprint library on the touch screen of the vehicle host system. When the user selects to add the fingerprint, the host system can prompt the user to place the finger at the in-vehicle fingerprint identification module through the touch screen, so that the in-vehicle fingerprint identification module collects the fingerprint of the user to generate fingerprint image information, the fingerprint image information is transmitted to the fingerprint module controller 110, the fingerprint module controller 110 extracts the characteristics of the details and the grains of the received fingerprint image to generate a fingerprint identifier, and the fingerprint identifier is stored in the fingerprint database. When the user selects to delete the fingerprint identifier stored in the fingerprint database, the host system may display, for example, a name of the stored fingerprint identifier (which may be set when the fingerprint database is stored) through the touch screen, so that the user may select which fingerprint identifier to delete, and after receiving, through the touch screen, the fingerprint identifier to be deleted selected by the user, the host system sends the fingerprint identifier to be deleted selected by the user to the fingerprint module controller 110, and the fingerprint module controller 110 deletes the fingerprint identifier selected by the user from the fingerprint database. Here, the method of storing and deleting the fingerprint identifier is only for illustration and is not intended to be particularly limited.
The fingerprint module controller 110 may identify whether the fingerprint repository stores the same fingerprint identifier as the generated first fingerprint identifier, for example, by traversing the fingerprint repository. The generated fingerprint recognition result R may indicate whether the fingerprint database stores the same fingerprint identifier as the generated first fingerprint identifier.
If the fingerprint identification result indicates that the fingerprint database stores the same fingerprint identification as the first fingerprint identification, the fingerprint module controller 110 forms at least the fingerprint identification result R, the random number a and the rolling code G into fingerprint data. The random number a may be generated by a random number generation device and a random number generation algorithm, and the random number a is a different random value at each transmission. The value of the rolling code G may be increased by a preset value, which may be, for example, 1 or an arbitrary value, each time it is transmitted. The fingerprint recognition result R, the random number a, and the rolling code G may be respectively set at specific positions of the fingerprint data. The fingerprinting module controller 110 may further send the composed fingerprint data to the processor 120.
The processor 120 may first extract the fingerprint identification result R, the random number a, and the rolling code G from the fingerprint data, for example, according to the positions of the fingerprint identification result R, the random number a, and the rolling code G in the fingerprint data. If the fingerprint identification result R indicates that the fingerprint database stores the same fingerprint identifier as the first fingerprint identifier, and the rolling code G indicates that the fingerprint data is legitimate, the processor 120 encrypts the random number a using the stored first key to generate a first encryption result. In this case, since the value of the rolling code G is increased by a preset value each time the rolling code G is transmitted, the processor 120 may determine whether a difference between the rolling code received at the current time and the rolling code received at the previous time is a preset value, and if so, determine that the fingerprint data is valid, otherwise, determine that the fingerprint data is invalid. The processor 120 may perform encryption using, for example, the AES 128 encryption method. The processor 120 may further send the first encryption result to the fingerprint module controller 110.
After the fingerprinting-module controller 110 receives the first encryption result, the random number a sent to the processor may be encrypted using the stored second key to generate a second encryption result. The second key is the same as the first key, and both are stored in advance. The secret key belongs to a unique value of the vehicle and can be converted from a vehicle chassis number, and different chassis numbers correspond to different secret key values. The fingerprint module controller 110 uses the same encryption method as the processor 120, for example, both may be AES 128 encryption methods. The fingerprinting module controller 110 may compare the generated second encryption result with the first encryption result generated by the processor 120, and may transmit an authentication success instruction to the processor if the first encryption result and the second encryption result are the same.
The processor 120, upon receiving the authentication success instruction, may honor the control instruction to the vehicle's actuator. For example, it may be an unlock instruction or a start instruction. By performing control of the vehicle according to the fingerprint data of the user, the control of the vehicle is no longer restricted by the physical key, and the theft prevention performance of the vehicle is made higher by the reliable transmission process and the encryption mechanism.
In an alternative embodiment, if the fingerprint identification result R determined by the fingerprint module controller 110 indicates that the fingerprint database does not store the same fingerprint identifier as the first fingerprint identifier in the above execution process, the fingerprint module controller 110 may for example feed back the fingerprint identification result R to the host system, and the host system may control the prompting device to issue a prompt based on the fingerprint identification result R, for example, may control the alarm device to issue an alarm. Optionally, if the rolling code G extracted by the processor 120 indicates that the fingerprint data is illegal, the processor 120 may feed back the fingerprint data to the host system, and the host system may control the touch screen to issue a text prompt based on the feedback, for example, may issue a text prompt indicating that the start is failed or the unlock is failed.
In a further alternative embodiment, the fingerprint module controller 110 may compare the calculated second encryption result with the first encryption result calculated by the processor 120, and transmit an authentication failure instruction to the processor if the second encryption result is determined not to be identical to the first encryption result. The processor 120 re-encrypts the random number a using the stored first key based on the received authentication failure instruction to regenerate the first encryption result, and transmits the regenerated first encryption result to the fingerprint module controller 110. After receiving the regenerated first encryption result, the fingerprinting module controller 110 encrypts the random number a according to the second key to regenerate the second encryption result, and further determines whether the regenerated first encryption result and the regenerated second encryption result are the same. If the two are the same, an authentication success instruction is sent to the processor 120, otherwise, an authentication failure instruction is sent. Based on the authentication failure instruction, the fingerprint module controller 110 and the processor 120 may repeatedly perform the above-described regeneration process of the first encryption result and the second encryption result. Optionally, the processor 120 does not regenerate the first encryption result in case that the authentication failure instruction is received more than the predetermined number of times, unless the fingerprint data transmitted by the fingerprint module controller 110 is received again. The number of times of subscription in the embodiment of the present invention may be set to any suitable value, for example, may be set to 10 times. By setting the number of times of regenerating the second encryption result and the first encryption result to be a limited number of times of reservation, the encryption mode, the key and the like of the embodiment of the invention can be prevented from being maliciously cracked.
Optionally, in the embodiment of the present invention, the processor 120 may be a passive entry and start system (cap system), and data transmission may be performed between the fingerprint module controller 110 and the cap system through a CAN bus.
The control system for the vehicle provided by the embodiment of the invention can be used for vehicle entrance and/or vehicle starting. Fig. 2 shows a block diagram of a control system for a vehicle according to still another embodiment of the present invention. As shown, the control system for a vehicle according to the embodiment of the present invention may further include an off-board fingerprint recognition module 130 and/or an in-board fingerprint recognition module 140.
In an alternative embodiment, the off-board fingerprint identification module 130 may be disposed outside the body of the vehicle, such as on a door handle of the vehicle, such as on the outside and inside of the door handle. The off-board fingerprint identification module 130 is used for collecting fingerprint information of a user, and when a finger of the user contacts the off-board fingerprint identification module 130, the fingerprint module controller 110 is awakened, and meanwhile, the fingerprint module controller 110 can awaken the processor 120 through a hard line. The off-board fingerprint identification module 130 may generate fingerprint image information by collecting fingerprint information of the user, for example, the fingerprint image information may be transferred to the fingerprint module controller 110 using a USB standard protocol. After receiving the fingerprint image information, the fingerprint module controller 110 may generate a fingerprint identifier, identify the fingerprint identifier, and generate and transmit fingerprint data. The processor 120, after receiving the fingerprint data, may perform the generation and transmission of the first encryption result. The fingerprint module controller 110 may generate the second encryption result and the authentication instruction. The specific implementation of the fingerprint module controller 110 and the processor 120 has been described in detail above, and will not be described herein again.
After receiving the authentication success instruction, the processor may send an unlocking instruction to the unlocking module of the vehicle, for example, the processor may first send the unlocking instruction to the gateway, and the gateway forwards the unlocking instruction to the unlocking module of the vehicle. And the unlocking module of the vehicle drives the door lock to unlock after receiving the unlocking instruction. The fingerprint data sent by the fingerprint module controller 110 to the processor 120 may also include an identifier of the fingerprint image information from the off-board fingerprint identification module, and based on the identifier, the processor 120 may send the unlocking instruction after receiving the authentication success instruction.
Optionally, the process of executing the vehicle entering may also be used for locking the vehicle, and the vehicle locking process is similar to the vehicle unlocking process, which will not be described herein again.
In an alternative embodiment, the in-vehicle fingerprint identification module 140 may be located in the vehicle, for example, may be integrated with the host system of the vehicle. The in-vehicle fingerprint identification module 140 may be used for entry of fingerprints, identification, and activation of the vehicle. The entry and deletion of fingerprints has been described above, and the start of the vehicle is mainly described here.
The in-vehicle fingerprint identification module 140 is configured to collect fingerprint information of a user to generate fingerprint image information, and may transmit the fingerprint image information to the fingerprint module controller 110 using, for example, a USB standard protocol. After receiving the fingerprint image information, the fingerprint module controller 110 may generate a fingerprint identifier, identify the fingerprint identifier, and generate and transmit fingerprint data. The processor 120, after receiving the fingerprint data, may perform the generation and transmission of the first encryption result. The fingerprint module controller 110 may generate the second encryption result and the authentication instruction. The specific implementation of the fingerprint module controller 110 and the processor 120 has been described in detail above, and will not be described herein again.
After receiving the authentication success instruction, the processor may send a start instruction to the unlocking module of the vehicle, for example, the processor may first send the start instruction to the gateway, and the gateway forwards the start instruction to the start module of the vehicle. The starting module can be an engine control unit, for example, and the engine control unit can drive the engine to be ignited and started after receiving a starting instruction. The fingerprint data sent by the fingerprint module controller 110 to the processor 120 may also include an identifier of the fingerprint image information from the in-vehicle fingerprint identification module, and based on the identifier, the processor 120 may send the start instruction after receiving the authentication success instruction.
The vehicle is accessed and/or started by using the control system of the vehicle, so that the vehicle can be accessed and/or started without depending on the physical key of the vehicle, and a user can access and/or start the vehicle without carrying the physical key.
Based on any of the above embodiments, in a further alternative embodiment, the control system for a vehicle provided by the embodiment of the invention can also be used for realizing a memory function of the vehicle. Specifically, when the user uses the finger that has successfully entered the fingerprint to touch the fingerprint identification module outside the vehicle or the fingerprint identification module inside the vehicle, the fingerprint identification module outside the vehicle or the fingerprint identification module inside the vehicle collects fingerprint information to generate a fingerprint image, and the fingerprint image is transmitted to the fingerprint module controller through the USB. The fingerprint module controller extracts the characteristics of the details and the grains of the fingerprint image to generate a first fingerprint identification, and matches the first fingerprint identification with the fingerprint identification stored in the fingerprint database to generate a fingerprint identification result. If the fingerprint identification result indicates that the fingerprint database stores the same fingerprint identification as the generated first fingerprint identification, the fingerprint identification result may be sent to one or more control modules, for example, the fingerprint identification result may be sent to a gateway in the fingerprint module controller, and the gateway forwards the fingerprint identification result to each control module. Wherein the one or more control modules may include one or more of: a seat memory module, an atmosphere light module, an audio control module, a rearview mirror control module, or an instrument adjustment module. And each control module can carry out corresponding memory setting according to the fingerprint identification result.
The fingerprint identification result can carry fingerprint identification or specific information of the fingerprint identification, the specific information can be a serial number or a name of the fingerprint identification, and the like, the characteristic information of the fingerprint identification corresponds to the fingerprint identification one by one, and each fingerprint identification corresponds to unique specific information. For example, after the fingerprint identification result carrying the fingerprint identification is received by each control module, the vehicle state can be set to be a memory state corresponding to the specific information before, for example, the seat memory module can adjust the seat position, the atmosphere lamp module can adjust the color of the atmosphere lamp, the audio control module can adjust the radio channel, the rearview mirror control module can adjust the position of the rearview mirror, or the instrument adjustment module can adjust the style state of the instrument. For example, if the first characteristic information corresponds to the fingerprint information of the vehicle owner, after the legal finger of the vehicle owner touches the external fingerprint identification module or the internal fingerprint identification module, the control modules memorize and set the vehicle state according to the first characteristic information. When the owner and wife use the vehicle, after the legal finger touches the external fingerprint identification module or the internal fingerprint identification module, the control modules can carry out memory adjustment on the vehicle state according to the second characteristic information of the wife fingerprint identification, so that the vehicle state is adjusted to the state set by the owner and wife before. It can be understood that a new user may manually set the vehicle state when first using the vehicle, and each control module may store the manual setting of the user for later use.
The memory setting of seat position, atmosphere lamp color, radio channel, rearview mirror position and instrument style is realized through fingerprint identification, so that the vehicle state automatically accords with the habit of a vehicle driver. And the number of the fingerprints which can be recorded can be a plurality of fingerprints, the limitation of the number of physical keys configured in the vehicle in the prior art is avoided, and the comfort, humanization and intellectualization of the vehicle are revealed.
Although the embodiment of the present invention has been illustrated by using fingerprints of human body, it is understood that the present invention may also be implemented by using any other biological features of human body, such as iris, face data, etc., and these variations fall within the scope of the embodiment of the present invention.

As shown in fig. 3, an embodiment of the present invention also provides a control method for a vehicle, which may include: performing, by the fingerprint module controller, the steps of: step S302, generating a first fingerprint identification according to the received fingerprint image information of the user; step S304, identifying whether a fingerprint identification which is the same as the first fingerprint identification is stored in a fingerprint database to generate a fingerprint identification result; and step S306, if the fingerprint identification result indicates that the fingerprint database stores the fingerprint identification which is the same as the first fingerprint identification, transmitting fingerprint data which is formed by at least the fingerprint identification result, the random number and the rolling code to a processor; the following steps are then performed by the processor: step S308, extracting the fingerprint identification result, the random number and the rolling code from the fingerprint data; step S310, if the fingerprint identification result indicates that the fingerprint database stores the same fingerprint identification as the first fingerprint identification and the rolling code indicates that the fingerprint data is legal, encrypting the random number by using a stored first secret key to generate a first encryption result; and step S312, transmitting the first encryption result to the fingerprint module controller; receiving, by the fingerprint module controller, the steps of: step S314, after receiving the first encryption result, encrypting the random number sent to the processor by using a stored second key to generate a second encryption result; step S316, if the first encryption result is the same as the second encryption result, transmitting an authentication success instruction to the processor; step S318 is executed by the processor, and the processor transmits a control command to the actuator of the vehicle after receiving the authentication success command. By performing control of the vehicle according to the fingerprint data of the user, the control of the vehicle is no longer restricted by the physical key, and the theft prevention performance of the vehicle is made higher by the reliable transmission process and the encryption mechanism.
