BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art.

[0021] Figure 1 It is a schematic structural diagram of the emergency stop control system provided by the embodiment of the present invention. DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present utility model. Therefore, the "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0024] In various embodiments of the present utility model, it should be understood that the magnitude of the sequence numbers of the following processes does not mean the sequence of execution. The execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present utility model.

[0025] An embodiment of the present utility model provides an emergency stop control system, as Figure 1 shown. The emergency stop control system 100 includes:

[0026] A vehicle-mounted terminal 110, a mobile terminal 120, and a brake controller 130;

[0027] The vehicle-mounted terminal 110 is respectively connected to the mobile terminal 120 and the brake controller 130;

[0028] Wherein, the vehicle-mounted terminal 110 is used to forward the emergency stop signal and the emergency stop release signal sent by the mobile terminal 120 to the brake controller 130.

[0029] The emergency stop control system provided by the embodiments of the present application is applied to a vehicle. The vehicle here can be an autonomous vehicle, such as an unmanned logistics vehicle. During the performance tuning test of the vehicle, when some unexpected situations occur and the vehicle needs to brake immediately, the emergency stop control system provided by the embodiments of the present application can be used to perform emergency stop control on the vehicle to avoid accidents and improve driving safety. The emergency stop control system specifically includes a vehicle-mounted terminal, a mobile terminal, and a brake controller. Among them, the vehicle-mounted terminal is wirelessly connected to the mobile terminal, and the vehicle-mounted terminal is connected to the brake controller through a Controller Area Network (CAN) bus.

[0030] The mobile terminal is the user's operating terminal. When the user needs the vehicle to brake immediately and stop, based on the wireless communication connection between the mobile terminal and the vehicle-mounted terminal, the user can send an emergency stop signal to the vehicle-mounted terminal by operating the mobile terminal. When the vehicle-mounted terminal receives the emergency stop signal sent by the mobile terminal, based on the communication connection between the vehicle-mounted terminal and the brake controller, the vehicle-mounted terminal forwards the emergency stop signal to the brake controller through the CAN bus, so that the brake controller controls the vehicle to perform an emergency brake. When the vehicle that has been emergently braked by the user through the emergency stop control system needs to resume normal driving, the user can send a cancel emergency stop signal to the vehicle-mounted terminal by operating the mobile terminal based on the wireless communication connection between the mobile terminal and the vehicle-mounted terminal. When the vehicle-mounted terminal receives the cancel emergency stop signal sent by the mobile terminal, based on the communication connection between the vehicle-mounted terminal and the brake controller, the vehicle-mounted terminal forwards the cancel emergency stop signal to the brake controller through the CAN bus, so that the brake controller cancels the braking control of the vehicle and enables it to resume normal driving.

[0031] Specifically, as the operating device of the emergency stop control system, the mobile terminal is provided with a first button for triggering an emergency stop signal and a second button for triggering a cancel emergency stop signal. Here, the first button and the second button can respectively correspond to one button, or can be one button, and this button alternately triggers the emergency stop signal and the cancel emergency stop signal when pressed. The wireless communication method between the mobile terminal and the vehicle-mounted terminal can be one of the following methods: WIFI, Bluetooth, NFC, infrared, mobile communication network, and this application does not make specific limitations on this.

[0032] Specifically, the brake controller receives the emergency stop signal sent by the mobile terminal, and sends a brake control signal to the intelligent brake system, and sends a brake caliper clamping control signal to the electronic parking brake system. The brake controller receives the cancel emergency stop signal sent by the mobile terminal, and sends a brake caliper release control signal to the electronic parking brake system.

[0033] The following introduces how the brake controller responds to the emergency stop signal and the cancel emergency stop signal.

[0034] After receiving the emergency stop signal forwarded by the vehicle-mounted terminal, the brake controller sends a brake control signal to the Intelligent Brake System (IBS), so that the IBS performs brake control on the vehicle by driving the brake caliper based on the brake control signal. When the vehicle speed drops to zero, the brake controller sends a brake caliper clamping control signal to the Electronic Parking Brake (EPB), so that the EPB drives the brake caliper to clamp based on the brake caliper clamping control signal, thereby realizing the emergency stop control of the vehicle.

[0035] After receiving the emergency stop cancellation signal forwarded by the vehicle-mounted terminal, the braking controller sends a brake caliper release control signal to the EPB, so that the EPB drives the brake caliper to release based on the brake caliper release control signal through an electrical signal, thereby enabling the vehicle to resume normal driving.

[0036] It should be noted that in the emergency stop control system of this application, the vehicle-mounted terminal and the mobile terminal are paired and connected to establish a wireless connection between the vehicle-mounted terminal and the mobile terminal, so that signal transmission can be realized based on this wireless connection, that is, the sending and receiving of the emergency stop signal and the emergency stop cancellation signal.

[0037] Among them, the pairing connection is that the vehicle-mounted terminal receives the power-on and power-off action signals and the emergency stop signal or emergency stop cancellation signal sent by the mobile terminal.

[0038] Specifically, the pairing connection can be that when the vehicle speed is zero, the vehicle-mounted terminal monitors that the vehicle performs the target number of power-on and power-off actions and the emergency stop signal or emergency stop cancellation signal sent by the mobile terminal within a preset duration. After the mobile terminal and the vehicle-mounted terminal are paired and connected in the above manner, the vehicle-mounted terminal also outputs a prompt tone to prompt the user that the vehicle-mounted terminal and the mobile terminal have completed the pairing connection. It should be noted that the above-mentioned execution of the target number of power-on and power-off actions can be the execution of the target number of power-on actions, or the execution of the target number of power-off actions, or the total number of power-on and power-off actions is the target number. Here, the total number of power-on and power-off actions is taken as an example for introduction. Optionally, the target number can be set to 4 times, and the preset duration can be set to 7 seconds. That is, within 7 seconds, the user presses the button on the mobile terminal for triggering the emergency stop signal or emergency stop cancellation signal and operates the vehicle to perform 2 power-on actions and 2 power-off actions.

[0039] When the user needs to perform an emergency stop control on the vehicle through the mobile terminal, it is first necessary to establish a wireless connection between the vehicle-mounted terminal and the mobile terminal, that is, the vehicle-mounted terminal and the mobile terminal complete the pairing connection through a preset method. Specifically, when the vehicle speed is zero, the first operation and the second operation are performed within a preset duration. The first operation is to operate the vehicle to perform the target number of power-on and power-off actions. Optionally, a third button can be set on the vehicle-mounted terminal, and by clicking the third button, the vehicle can be triggered to perform the target number of power-on and power-off actions, that is, the above-mentioned first operation is completed. The second operation is to send an emergency stop signal or an emergency stop cancellation signal through the mobile terminal, that is, click the signal trigger button set on the mobile terminal, which can be the first button or the second button. It should be noted that before establishing the pairing connection, the mobile terminal can broadcast and send the emergency stop signal or the emergency stop cancellation signal, and the vehicle-mounted terminal can receive the signal, but the signal will not be responded to by the vehicle-mounted terminal of the vehicle, and only serves as a request signal for establishing the pairing connection. The above-mentioned first operation and second operation do not distinguish the order.

[0040] Specifically, when a user conducts a performance tuning test on a vehicle, it is not necessary to configure a mobile terminal for each vehicle, that is, the mobile terminal is only bound to the on-vehicle terminal of one vehicle. Instead, the mobile terminal can be bound to multiple vehicles respectively. For example, when conducting a performance tuning test on the first vehicle, the mobile terminal is paired and bound to the first vehicle. After the first vehicle completes the test and the second vehicle is to be tested, the mobile terminal can be paired and bound to the second vehicle. Optionally, the mobile terminal can be paired and bound to multiple vehicles simultaneously, and each vehicle can correspond to a set of control components (i.e., the above-mentioned first button and second button) on the mobile terminal, so that when testing multiple vehicles simultaneously, the emergency stop control of multiple vehicles can be achieved through one mobile terminal.

[0041] Furthermore, the on-vehicle terminal can include a verification module for verifying the emergency stop signal and the emergency stop release signal, and forwarding them to the brake controller after verification, so as to prevent the brake controller from responding to the unverified emergency stop signal and emergency stop release signal, improving the safety of the emergency stop control system while maintaining the usability.

[0042] Furthermore, the brake controller and the on-vehicle terminal in the embodiments of the present application can be the body controller of the vehicle, that is, the on-vehicle terminal and the brake controller are integrated on the body controller.

[0043] In the above implementation scheme of the present utility model, the on-vehicle terminal is respectively connected to the mobile terminal and the brake controller, and the on-vehicle terminal forwards the emergency stop signal and the emergency stop release signal sent by the mobile terminal to the brake controller, so that the brake controller can control the vehicle to perform emergency braking according to the emergency stop signal and release the braking control of the vehicle according to the emergency stop release signal. Thus, when an accident may occur during the vehicle performance tuning test, the vehicle can be remotely controlled to perform an emergency stop in a timely manner through the mobile terminal, with simple operation and ensuring driving safety.

[0044] The embodiments of the present utility model also provide a vehicle, including the above-mentioned emergency stop control system.

[0045] Specifically, in a vehicle equipped with the above-mentioned emergency stop control system, the on-vehicle terminal is respectively connected to the mobile terminal and the brake controller, and the on-vehicle terminal forwards the emergency stop signal and the emergency stop release signal sent by the mobile terminal to the brake controller, so that the brake controller can control the vehicle to perform emergency braking according to the emergency stop signal and release the braking control of the vehicle according to the emergency stop release signal. When an accident may occur during the vehicle performance tuning test, the vehicle can be remotely controlled to perform an emergency stop in a timely manner through the mobile terminal, with simple operation and improving driving safety.
