Description

Electric vehicle wireless central control system based on low-power-consumption Bluetooth center network topology

Technical Field

The invention relates to the technical field of control of power equipment, in particular to a wireless central control system based on a low-power-consumption Bluetooth (BLE) center network topology structure, which is easy to expand each functional module of an electric vehicle.

Background

The electric vehicle, also called a power-assisted vehicle (two-wheeled or three-wheeled), is developed very rapidly at present in China, and along with the development of the internet, the electric vehicle is more and more intelligent and is networked, so that the electric vehicle can be added with more and more functional module devices. The traditional electric vehicle is not provided with a unified international standard and a unified protocol on a connecting bus like an automobile, so that a motor controller of the traditional electric vehicle charges a control center of the whole electric vehicle, and because the motor controller is the control center, the control lines for all functional components are very many (for example, fig. 1 shows a traditional controller outgoing line diagram and fig. 2 shows a traditional electric vehicle structure schematic diagram), and the number of the wiring is as many as 31 or even more, so that the wiring is difficult to assemble in various large vehicle factories, but the electric vehicle is developed towards an internet-based intelligent electric vehicle.

Referring to fig. 1 and 2, a conventional electric vehicle structure is a system built with an electric vehicle controller as a center, and since all devices surround the electric vehicle controller (shown in fig. 2), the electric vehicle controller has a large number of outgoing lines (shown in fig. 1).

At present, a plurality of intelligent electric vehicles on the market use Bluetooth Low Energy (BLE) as a control interface of the electric vehicle, for example, the electric vehicle can be operated (for example, locking, unlocking, powering on and the like) by opening the APP on a smart phone, but the Bluetooth Low Energy (BLE) at a mobile phone end is in a master mode, and the Bluetooth Low Energy (BLE) at the electric vehicle end is in a slave mode and is one-to-one based and cannot be wirelessly expanded.

Every time a function is added to the electric vehicle, corresponding devices and corresponding connecting wires need to be added, so that the wiring harness of the whole vehicle is thicker and thicker, the wiring is complex, the cost is higher and higher, the threading installation is difficult, and once a fault occurs, the fault source is difficult to find. Meanwhile, with the intellectualization of the electric vehicle system, the original whole vehicle wiring harness cannot meet the requirements of new functions.

Secondly, along with the development of mobile internet, traditional electric motor car is all facing towards the development of intelligent electric motor car, for example calf electric motor car, yadi Z3 intelligent electric motor car, but user's free choice can't be accomplished to this intelligent electric motor car's function, just take typical calf electric motor car, the function is that the manufacturer has just confirmed when dispatching from the factory, the unable free selection of user and a function of collocation belong to the required electric motor car that can satisfy individuality of oneself completely.

Bluetooth Low Energy (BLE) centric network topology: the method is characterized in that one of the two BLE chips realized through a software protocol stack time sharing technology through a single BLE chip or a hardware circuit can be used as a slave mode device to be scanned and connected by a mobile phone, and can also be used as a master mode device to scan and connect the slave mode device.

The Bluetooth Low Energy (BLE) central network topology is not the standard of the Bluetooth Low Energy (BLE), so the invention provides a word called the Bluetooth Low Energy (BLE) central network topology, and the device is called a Bluetooth Low Energy (BLE) central network topology module.

As background for implementing the present invention, the BLE4.0 bluetooth technology, which is commonly used, must be explained.

In general, bluetooth Low Energy (BLE) has two roles as options, namely a master mode and a slave mode.

Typically, a Bluetooth Low Energy (BLE) system can only be used as one mode at a time.

A main mode: scanning, connecting, typically a maximum of 8 Bluetooth Low Energy (BLE) devices can be connected as slave mode devices (handsets typically are master mode devices).

From the mode: scanned, connected, and only connected by one master mode device (the function extension module with low energy Bluetooth (BLE) generally serves as a slave mode device).

For example:

smart mobile phone and Bluetooth Low Energy (BLE) bracelet, smart mobile phone can connect 8 Bluetooth Low Energy (BLE) bracelets at most simultaneously as master mode party, and Bluetooth Low Energy (BLE) bracelet is as the slave mode party, can only be connected by a smart mobile phone simultaneously.

The function expansion module device with the Bluetooth Low Energy (BLE) is composed of a peripheral function expansion circuit and a Bluetooth low energy module circuit, and the function of the electric vehicle is expanded by establishing a Bluetooth low energy communication link between a wireless central control device based on a Bluetooth Low Energy (BLE) central network topology structure and the function expansion module device with the Bluetooth Low Energy (BLE).

The wireless central control device is one of the functional modules in the electric vehicle, the wireless central control device is an integrated structure formed by the wireless central control module and other functional modules of the electric vehicle together, and the other functional modules of the electric vehicle comprise any one or more of an anti-theft alarm module of the electric vehicle and an instrument panel of the electric vehicle, or are formed by a wireless central control module circuit alone.

The wireless central control device has at least two modes, the first mode is to allow the smart phone APP to scan and connect and establish a binding relationship with the wireless central control device, and the first mode can be activated only by a wireless remote control key; the second mode is that only the bound smart phone APP can establish a communication link with the wireless central control device, and the unbound smart phone APP is not allowed to establish a communication link with the wireless central control device.

The wireless central control device has the capability of binding the authorization with the smart phone APP through the Bluetooth Low Energy (BLE), and only the bound authorized smart phone APP can communicate and control with the wireless central control device of the smart electric vehicle.

The wireless central control device is in a state of continuous low-power-consumption Bluetooth broadcasting under the condition that the wireless central control device is electrified and is not connected with the binding-associated smart phone APP.

The Bluetooth low energy function extension module device comprises a Bluetooth low energy induction key, a Bluetooth low energy BMS battery management module, a Bluetooth low energy tire pressure detection module and a Bluetooth low energy GPRS/GPS tracking anti-theft module, wherein the Bluetooth low energy function extension module device is always in a Bluetooth low energy slave mode in interaction with the wireless central control device and comprises any one or combination of multiple Bluetooth low energy induction keys, bluetooth low energy BMS battery management modules, bluetooth low energy tire pressure detection modules and Bluetooth Low Energy (BLE) GPRS/GPS tracking anti-theft modules.

A wireless central control system based on a low energy consumption Bluetooth (BLE) central network topology is shown in figure 3 and is provided with a device of a wireless central control module. The device can be a combination of a wireless central control module and a certain functional module of the electric vehicle (such as an anti-theft alarm with the wireless central control module, an instrument panel with the wireless central control module and the like), wherein the wireless central control module has two construction modes: the condition of using the common wireless remote control key mode consists of a common wireless remote control receiving module and a low-power Bluetooth (BLE) central network topology module; or the mode of using the bluetooth low energy sensor key only needs a Bluetooth Low Energy (BLE) central network topology module (please refer to fig. 4, which shows that S101 and S102 are two construction structures of the ordinary wireless remote control key and the bluetooth low energy sensor key of the present invention).

The wireless central control device can be in the roles of the Bluetooth master mode and the Bluetooth slave mode simultaneously in the system, namely the role capable of scanning and initiating connection, and the role capable of broadcasting, being scanned and being connected. For a smart phone, the wireless central control device is always in a slave mode. For a Bluetooth Low Energy (BLE) function extension module device, the wireless central control device is always in a master mode.

The wireless remote control key has the functions of sending a key instruction to the wireless central control module, and more importantly, triggering the binding mode of the wireless central control module through a certain key instruction so as to bind the wireless central control device with the smart phone APP. Because the installation of wireless central control device with the electric motor car, in other words under binding the mode, the smart mobile phone APP that does not bind just can bind with the electric motor car of having installed wireless central control device.

Binding purpose: there are many ways to bind Bluetooth Low Energy (BLE), the invention does not make requirements on the binding form (for example, binding through mac address, binding bluetooth IRK, or logging in authentication through connected application layer), and the binding is for realizing: the two devices bound to each other can be automatically connected and communicate within the range of low-power Bluetooth Low Energy (BLE) communication, and the two unbound devices cannot be automatically connected and communicate with each other.

1. The following focuses on an embodiment of how to construct a wireless central control device based on a Bluetooth Low Energy (BLE) centric network topology:

1. the core of constructing the wireless central control device is to construct a wireless central control module with a Bluetooth Low Energy (BLE) central network topology (as shown in fig. 3), and the construction of the wireless central control module may be in two ways (please refer to fig. 4, which shows that S101 and S102 are two construction structures of a normal wireless remote control key and a Bluetooth Low Energy (BLE) induction key of the present invention).

In fig. 4, S101 indicates that when a conventional wireless remote control key with a radio frequency transmitter is used in an electric vehicle, the wireless central control module of the present invention is composed of a conventional wireless remote control receiving module, a low-power-consumption Bluetooth (BLE) central network module, and a master controller.

S102 in fig. 4 indicates that the wireless central control module of the present invention is formed by a Bluetooth Low Energy (BLE) central network module circuit and a master controller when a Bluetooth Low Energy (BLE) sensor key with a Bluetooth Low Energy (BLE) chip is used. Under the construction mode, a wireless remote control receiving module circuit is not needed for the wireless central control module, and the low-power-consumption Bluetooth (BLE) induction key can be considered as one of the function extension modules with the low-power-consumption Bluetooth (BLE), but the low-power-consumption Bluetooth (BLE) induction key is bound with the wireless central control device directly when leaving a factory, the receiving module is not needed, and the wireless central control device can automatically scan and connect when the low-power-consumption Bluetooth induction key is close to the wireless central control device. The mode can also meet the condition that the key triggers the binding mode of the wireless central control module.

In this scheme, bluetooth Low Energy (BLE) central network module and main control unit module can be the mode of bluetooth chip + singlechip, also can be for having practiced thrift the cost, is replaced the function of the main control of singlechip by the bluetooth chip.

2. Construction of low-power consumption Bluetooth (BLE) central network module circuit

Fig. 5 shows two topologies of Bluetooth Low Energy (BLE) centric network modules implemented by the present invention, i.e., the construction of the Bluetooth Low Energy (BLE) centric network module. There are two general approaches: a single Bluetooth Low Energy (BLE) chip mode and a dual Bluetooth Low Energy (BLE) chip mode.

(1) Please refer to the upper part of fig. 5, which shows the circuit structure of the single BLE chip 201: the protocol stack of the BLE chip supporting the tasks of the parallel multilink center (master mode) and the peripheral (slave mode) is required, the protocol stack switches the roles of the BLE as the center device (master mode) and the peripheral device (slave mode) in a time sharing mode, but the switching time is very short, so that people feel that the BLE chip has the roles of the center device and the peripheral device at the same time from the sense of view.

(2) Fig. 5 shows a circuit structure using dual BLE chips 202, such that one BLE chip mainly works as a peripheral device (slave mode) role to communicate with a mobile phone, another BLE chip scans as a central device (master mode) role to connect functional devices as peripheral devices (slave mode), and up to 8 BLE chips communicate with each other by using physical connections (such as UART, SPI, IIC, etc., without limitation).

Both modes are feasible, because the existing promotion that a single BLE chip supports the BLE chips with the functions through role time-sharing switching is not enough, the invention constructed by adopting the double BLE chips has larger selectivity, and the single BLE chip does not necessarily have advantages over the double BLE chips in cost.

Fig. 6 shows some embodiments of the present invention, which can be extended by Bluetooth Low Energy (BLE) (central network topology), and shows that the topology of the wireless central control device of the electric vehicle with the Bluetooth Low Energy (BLE) central network module extends the Bluetooth Low Energy (BLE) remote control key, the Bluetooth Low Energy (BLE) BMS battery management module, the Bluetooth Low Energy (BLE) tire pressure detection module, the Bluetooth Low Energy (BLE) GPRS/GPS tracking anti-theft module, the Bluetooth Low Energy (BLE) dashboard, and other Bluetooth Low Energy (BLE) extensible modules.

2. How smart mobile phone APP binds to an embodiment of a wireless central control device based on a Bluetooth Low Energy (BLE) central network topology:

the smart phone APP and the wireless central control device can be bound in a binding mode, the binding mode is activated by a wireless remote control key, and otherwise, the wireless central control device is in a general mode. There are various implementation manners for the binding between Bluetooth Low Energy (BLE) and the wireless central control device APP, and here, only the binding mode that requires the wireless remote control key to activate the wireless central control device is emphasized, and the specific binding manner is not limited, and it is only required to satisfy the above-mentioned binding purpose after binding, in this binding relationship, the wireless central control device APP is always in the role of the master mode, and the wireless central control device is in the role of the slave mode.

3. Examples of binding of a wireless central control device and a Bluetooth Low Energy (BLE) function extension module device:

there are two types of binding modes between the wireless central control device and the low-power-consumption Bluetooth (BLE) function extension module device: one is binding by factory production tools at the time of shipment. And secondly, after leaving the factory, the mobile phone bound with the wireless central control device is added and bound in the hand of the user, so that the binding relationship between the wireless central control device and the low-power-consumption Bluetooth (BLE) function extension module device is established, and the binding mode is not limited (for example, the Bluetooth mac address of the low-power-consumption Bluetooth (BLE) function extension module device is registered in the wireless central control device), and only the binding purpose is required to be met.

The wireless central control device is always in a broadcast state, and under the condition that the wireless central control device is not connected with the smart phone, the bound smart phone can initiate connection and establish a communication link with the smart phone after receiving the broadcast within the Bluetooth communication range, and the unbound smart phone can be connected with the wireless central control device and bound with the wireless central control device only under the condition that the wireless remote controller activates the binding mode of the wireless central control device.

The wireless central control device is always in a scanning state, when the bound Bluetooth Low Energy (BLE) function extension module device approaches, the wireless central control device initiates connection, establishes a communication link with the bound BLE function extension module device, and performs management and interaction according to the bound type, so that functions are extended.

In the embodiment, the bound smart phone APP is connected with the smart electric vehicle.

The intelligent electric vehicle that has been bound by smart mobile phone APP is in the state of ordinary broadcasting under the state of not connecting the cell-phone to contain the only bluetooth mac address of this vehicle in the broadcast package, the smart mobile phone APP that has bound this intelligent electric vehicle can automatic connection this vehicle in bluetooth communication distance, and submit the login password, the password is by server random assignment when binding, this password is checked to the intelligent electric vehicle, if with the unanimity of distribution when binding, then allow this vehicle of this smart mobile phone APP control, if inconsistent or within 5 seconds submit the password, then disconnect the bluetooth connection.

In the embodiment, the smart mobile phone APP and the intelligent electric vehicle that have bound are in the effectual connection range of bluetooth, and the smart mobile phone APP can establish the link with this intelligent electric vehicle automatically to it is mutual, for example give some orders: arming, disarming, searching vehicles and the like.

In the embodiment, the binding step of the intelligent electric vehicle and the low-power Bluetooth induction key (Bluetooth low-power function extension module) comprises the following steps:

fig. 9 shows an embodiment of binding a low-power bluetooth alarm and a low-power bluetooth sensor key according to the present invention, which shows how to bind a Bluetooth Low Energy (BLE) function extension module to an intelligent electric vehicle by a smart phone APP. The process can be carried out without the participation of a network server or in a scanning mode, and only the binding purpose in the technical scheme can be realized.

In this embodiment, the bluetooth low energy sensor key is an example of a bluetooth low energy function extension module, and is bound in a code scanning manner. The low-power-consumption Bluetooth induction key is used as an optional accessory of the intelligent electric vehicle, a unique one-dimensional code is generated when the intelligent electric vehicle leaves a factory, and the Bluetooth mac address and the type of the low-power-consumption Bluetooth induction key are associated with the one-dimensional code and stored on a network server when the intelligent electric vehicle leaves the factory.

The user need bind this bluetooth low energy response key to the intelligent electric motor car on, need go on through the smart mobile phone APP that has bound.

1) The bound smart phone APP firstly needs to establish link connection with the smart electric vehicle, and then one-dimensional codes on the code low-power-consumption Bluetooth induction key are scanned.

2) And submitting the one-dimensional code to a server to obtain the mac address and the type (the type is the low-power Bluetooth induction key) of the low-power Bluetooth induction key.

3) The binding is completed by writing the mac address and type of the low-power-consumption Bluetooth induction key into the intelligent electric vehicle.

4) And removing the binding, namely deleting the mac address of the low-power-consumption Bluetooth induction key through the smart phone APP.

The following describes how to implement the expansion of the function after the bluetooth low energy proximity key is bound, which is similar to the keyless start function in an automobile.

The intelligent electric vehicle scans the broadcast of the low-power Bluetooth induction key, confirms that the mac address of the low-power Bluetooth induction key bound with the vehicle is consistent through the mac address of a broadcast packet, and initiates connection with the low-power Bluetooth induction key. Since the Bluetooth Low Energy (BLE) connection belongs to a short-distance connection, if the connection is established with the smart electric vehicle, the bluetooth low energy sensing key is considered to be near the vehicle, and if the connection is not established with the bluetooth low energy sensing key, a person holding the key is not near the electric vehicle. According to the principle, arming and disarming of the electric vehicle can be set, keyless starting similar to that of an automobile can be realized by arranging a button on the intelligent electric vehicle, and when a key is near the automobile, the automobile can be started by pressing the button.

Similarly, if a BMS battery management module with bluetooth low energy (a bluetooth low energy function extension module device) is to be extended, the module device is bound to an intelligent electric vehicle, and the intelligent electric vehicle can read battery information by establishing a Bluetooth Low Energy (BLE) link with the module device to perform charging and discharging management.

Low-power consumption Bluetooth (BLE) extension module device is bound to intelligence electric motor car, can just bind through the instrument when leaving the factory, also can bind by the user later stage.

The type of the bound Bluetooth Low Energy (BLE) extension module device can be acquired from a server in a code scanning mode, and can also be read through a communication link after a link is established between the bound Bluetooth Low Energy (BLE) extension module device and a vehicle. Knowing the type of the extension module, i.e. knowing which functions the module carries, the extension of the corresponding functions can be performed.

In practical applications, various expandable Bluetooth Low Energy (BLE) expansion module devices may be introduced, but they are within the protection scope of the present invention as long as they do not depart from the core spirit of the present invention.
