Description

Technical Field

[0001] This utility model belongs to the field of automobile anti-theft. Specifically, this utility model relates to an automobile anti-theft starting control system and an automobile. Background Technology

[0002] Currently, there are many types of car anti-theft systems, and their main function is to achieve mutual recognition between the vehicle's unique unlocking and locking devices, enabling the vehicle to start under certain conditions. In some regions, there is a strong demand for car anti-theft systems. Under these market conditions, it is necessary to achieve car anti-theft functions at a low cost while quickly meeting market demands.

[0003] However, existing car anti-theft systems are often overly complex, requiring verification codes or identity recognition processes to be added to the vehicle's internal data communication to achieve anti-theft. For example, prior art document (CN117681826A) discloses a method, device, and anti-theft network equipment for power anti-theft authentication, which is applied to a vehicle integration unit. The method includes: after the vehicle is powered on, obtaining a power anti-theft permission flag bit sent by the vehicle data center; sending the power anti-theft permission flag bit to the key controller; receiving an authentication request sent by the key controller after obtaining the power anti-theft permission flag bit and receiving a brake signal; and performing decryption authentication with the key controller according to the authentication request. After the vehicle is powered on, the key controller receives the power anti-theft permission flag bit sent by the vehicle integration unit. When the user presses the brake, the key controller initiates an authentication request to the vehicle integration unit and completes power anti-theft authentication with the vehicle integration unit. Compared with most existing power anti-theft authentication technologies that use one-button start plus brake or brake plus gear shift as the initiation condition, this is faster and more convenient. Pressing the brake initiates power anti-theft authentication, improving the user experience.

[0004] Existing technologies such as those mentioned in the comparative documents, while achieving car anti-theft, require overly complex communication data settings and architectures, are highly dependent on a secure and reliable network environment, and are costly and difficult to deploy.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the terms "first," "second," etc., used in this application are only for the convenience of describing the technical solution and distinguishing different components, and are not intended to limit this application. To make the technical solution of this utility model clearer, it will be explained and illustrated through the following embodiments.

[0017] A car anti-theft start control system, such as Figure 1 As shown, the system includes a remote key, an ignition switch, an anti-theft controller, a starter controller, a starter relay, a starter motor, a battery, an IGN power supply, and an alarm device. The positive terminal of the battery is connected to the ignition switch, the anti-theft controller, the starter controller, the starter relay, and the alarm device. The remote key is communicatively connected to the anti-theft controller. The IGN power supply is connected to the ignition switch, the anti-theft controller, and the starter controller. The ignition switch is connected to the anti-theft controller. The starter controller is connected to the anti-theft controller and the starter relay. The anti-theft controller is connected to the starter relay and the alarm device. The starter relay is connected to the starter motor. The starter motor is connected to the negative terminal of the battery.

[0018] Specifically, an ignition switch typically has four positions: OFF (off position), ACC (vehicle accessory power-on position), ON (vehicle electrical circuit connection position), and START (start position). Different positions require different power supplies. In this embodiment, the ignition switch power supply terminals include: terminals 30 and 30A, both connected to the battery to provide constant power; terminals IG1 and IG2, both connected to the IGN power supply; the ACC terminal, typically connected to the ACC power supply (vehicle accessory power supply, generally powered by the battery before starting the car and by the alternator after starting); and the START terminal, used to output the ignition switch start signal. In this embodiment, the ST terminal is connected to the anti-theft controller.

[0019] In this embodiment, the remote key is used to remotely control the anti-theft controller. When the remote key locks the device, the anti-theft controller is in anti-theft mode. When the remote key unlocks the device, the anti-theft controller is in de-anti-theft mode.

[0020] The battery and IGN power supply are used to power the components connected to them. This multi-power supply mode ensures the normal operation of all components in the system, especially the anti-theft controller, under various vehicle usage conditions. For example, the anti-theft controller is powered by the IGN power supply when the ignition switch is in the ON position or the car is in anti-theft mode to ensure the normal operation of the car anti-theft system; when the car is starting normally, it is powered by the battery to prevent the vehicle from stalling due to the anti-theft controller being misactivated, thereby ensuring vehicle driving safety.

[0021] To further protect circuit safety, this embodiment provides fuses between the positive terminal of the battery and the ignition switch, anti-theft controller, starter controller, starter relay, and alarm device to protect the circuit; similarly, fuses are provided between the IGN power supply and the ignition switch, anti-theft controller, and starter controller to protect the circuit.

[0022] In this embodiment, one end of the coil of the starting relay is connected to the starting controller, and the other end of the coil is connected to the anti-theft controller. The first control contact of the starting relay is connected to the positive terminal of the battery, and the second control contact of the starting relay is connected to the starter motor. The starting relay is used to control the excitation on / off of the starter motor according to the control signals of the starting controller and the anti-theft controller.

[0023] The anti-theft controller in this embodiment includes a remote communication module. The remote communication module is communicatively connected to the remote control key and is used to receive remote control signals from the remote control key to control the activation and deactivation of the anti-theft mode of the anti-theft controller. The remote communication module can be built based on remote communication technologies such as radio technology and WiFi technology. In this embodiment, the remote communication module is a vehicle-mounted T-BOX. Vehicle-mounted T-BOX is a commonly used remote communication method by those skilled in the art, and will not be elaborated upon here.

[0024] This application achieves car anti-theft mode establishment solely through the addition of an anti-theft controller and remote key, resulting in a simple structure, convenient operation and installation, and reduced costs. The anti-theft controller in this embodiment has simple control logic. When the anti-theft controller is in anti-theft mode, if the ignition switch is in the START position, the ignition switch's start signal will be intercepted by the anti-theft controller and will not reach the starter relay and starter controller. Consequently, the starter motor will not be energized and will not work, preventing ignition. Furthermore, when the anti-theft controller receives a start signal from the ignition switch in the START position while in anti-theft mode, it assumes the vehicle is in an unsafe state and will send an abnormal alarm signal to the alarm device. When the anti-theft controller is in de-anti-theft mode, if the ignition switch is in the START position, the ignition switch's start signal can reach the anti-theft controller and connect to the starter relay and starter controller. The starter controller then controls the starter relay to conduct, allowing the starter motor to operate normally and drive the engine, enabling successful vehicle ignition. In this embodiment, the anti-theft controller can use microcontrollers, Arduino boards, or other microcontroller chips; the appropriate chip can be selected based on the specific implementation requirements. The anti-theft controller has a simple and integrated structure, does not require complex peripheral circuits, is not easily affected by network environment and external signal interference, reduces costs and improves system reliability.

[0025] The alarm device in this embodiment includes a remote monitoring device connected to the remote communication module. This remote monitoring device is used to remotely alert the vehicle owner when a risk of theft is detected. In this embodiment, the remote monitoring device can be a smartphone, smart bracelet, tablet, or other similar device. These devices can establish a connection with the vehicle's remote communication module via communication technologies such as WiFi, radio, and Bluetooth. This allows them to receive abnormal alarm signals from the anti-theft controller, promptly alerting the vehicle owner to any vehicle malfunction and preventing theft.

[0026] Furthermore, the alarm device in this embodiment also includes a horn relay, a horn switch, and a horn. The first end of the horn relay coil is connected to both the first end of the horn switch and the anti-theft controller, and the second end of the horn switch is grounded. The second end of the horn relay coil and its first control contact are connected to the positive terminal of the battery. The second control contact of the horn relay is connected to the horn and then grounded. The horn relay is used to control the horn to sound an alarm based on the control signal from the anti-theft controller and the state of the horn switch. Upon receiving an abnormal alarm signal from the anti-theft controller, the horn switch closes, causing the relay coil to conduct and the contacts to close, thereby enabling the horn to emit a sound alarm.

[0027] Preferably, the starter controller in this embodiment is an Electronic Control Unit (ECU). The ECU is a vehicle controller commonly used by those skilled in the art, serving as the central hub of an automotive electronic control system. It primarily controls various engine parameters and functions, thereby improving engine performance. This embodiment integrates a portion of the starter relay control into the ECU, avoiding the need to reselect and deploy a new controller, thus reducing costs. Furthermore, the dual control of the starter relay coil by the ECU and the anti-theft controller significantly reduces the possibility of the starter relay malfunctioning, improving the vehicle's anti-theft effectiveness.

[0028] This application applies to traditional gasoline-powered vehicles. It utilizes the connection and control strategy between an anti-theft controller, remote key, ignition switch, starter controller, starter relay, starter motor, battery, and alarm device. When the ignition key is turned without unlocking the anti-theft controller, the vehicle cannot be started, and the alarm will be activated, thus serving as a vehicle anti-theft measure. This anti-theft start control system has a simple structure and control logic, is reliable, and is easy to install.

[0029] In addition, this application also proposes a car that includes the aforementioned car anti-theft start control system.

[0030] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
