[0039] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] The embodiments of the present application provide an intelligent driving emergency stop control method, device, equipment and readable storage medium, which can solve the problem in the related art that safety accidents occur because unmanned vehicles are unable to stop urgently in the face of emergencies.

[0041] To achieve the above objectives, the overall idea of this application is as follows:

[0042] An intelligent driving emergency stop control method, the method comprising the following steps:

[0043] Step S10: When an emergency stop signal is received from a switch module fixed on the vehicle, the powertrain is controlled to stop outputting power and the brake system is controlled to perform emergency braking. The emergency stop signal is an emergency stop request signal sent by a remote control terminal or an emergency stop request signal generated by a manually controlled switch module.

[0044] Step S20: obtaining the real-time speed of the vehicle and determining whether the real-time speed is zero;

[0045] Step S30: If the real-time vehicle speed is zero, the vehicle is controlled to be in a parking state and a locked state.

[0046] See also Figure 1 and Figure 2 As shown, the embodiment of the present application provides an intelligent driving emergency stop control method, comprising the following steps:

[0047] Step S10: When an emergency stop signal is received from a switch module fixed on the vehicle, the powertrain is controlled to stop outputting power and the brake system is controlled to perform emergency braking. The emergency stop signal is an emergency stop request signal sent by a remote control terminal or an emergency stop request signal generated by a manually controlled switch module.

[0048] For example, it should be understood that the switch module in this embodiment is composed of a switch element, a signal receiver and a processing submodule; wherein the switch element is used for manual control, that is, the opening and closing of the switch element can be controlled by manually tapping, and the electrical signal generated by the opening and closing of the switch element will be transmitted to the processing submodule as an emergency stop request signal, so that the processing submodule generates an emergency stop signal; the processing submodule is not only used to convert the electrical signal generated by the switch element into an emergency stop signal, but also when the emergency stop request signal sent by the remote control terminal (such as a remote remote controller, a remote remote controller, etc.) is received through the signal receiver, the emergency stop request signal will also be converted into an emergency stop signal. Therefore, during the intelligent driving debugging and operation of the unmanned vehicle, when facing an emergency, an emergency stop signal can be generated by manually tapping the switch module on the vehicle, and during operation, when a pedestrian or vehicle suddenly appears in front of the vehicle through remote monitoring, an emergency stop request signal can also be sent to the switch module through the remote control or remote console, thereby generating an emergency stop signal to indicate that an emergency situation exists and an emergency stop is required.

[0049] It should be noted that the switch element can be a push button switch, a tap switch, a touch switch, etc. The specific type of switch used as the switch element can be determined according to actual needs and is not limited here.

[0050] It is understood that the switch module can be installed at any location within the vehicle, such as the front or rear, based on actual needs and not limited here. Furthermore, the switch module can be connected to the HCU (Hybrid Control Unit) via a CAN (Controller Area Network) line, allowing the HCU to determine whether the vehicle is facing an emergency situation requiring an emergency stop based on whether it receives an emergency stop signal transmitted by the switch module, and then automatically control the vehicle's powertrain to stop power output and the braking system to perform emergency braking.

[0051] Specifically, when the vehicle controller HCU detects the emergency stop signal sent by the switch module, it can determine that the vehicle is facing an emergency and needs to be stopped urgently. At this time, a power stop output command can be issued to the vehicle powertrain, and an emergency braking command can be issued to the braking system at the same time, so that the vehicle can stop power output and emergency braking. The driving power output can be stopped and the emergency braking can be stopped in the shortest time, thereby effectively reducing the possibility of safety accidents.

[0052] Furthermore, the switch module includes a first emergency stop switch and a second emergency stop switch, wherein the first emergency stop switch is fixed at the front of the vehicle and the second emergency stop switch is fixed at the rear of the vehicle. Preferably, the switch module includes four emergency stop switches, wherein two of the emergency stop switches are fixed at the front of the vehicle and the other two are fixed at the rear of the vehicle.

[0053] For example, it is understandable that when a vehicle faces an emergency, it should be parked as quickly as possible, which means that multiple locations are required to trigger parking operations. Therefore, in order to trigger parking operations as quickly as possible, emergency stop switches can be installed on the front, rear, and middle of the vehicle, so that on-site personnel can immediately touch the emergency stop switch at the location closest to their location, and then trigger the generation of an emergency stop signal by opening and closing the emergency stop switch. In order to further reduce the time to trigger the parking operation and achieve more accurate vehicle locking operations, this embodiment can install an emergency stop switch on each side of the front, rear, and middle of the vehicle, for example, see Figure 3 As shown, emergency stop switches 1 and 2 are arranged at the front of the vehicle, and emergency stop switches 3 and 4 are arranged at the rear of the vehicle to facilitate operation by on-site personnel.

[0054] Step S20: obtaining the real-time speed of the vehicle and determining whether the real-time speed is zero;

[0055] For example, in this embodiment, after the vehicle controller (HCU) controls the powertrain to stop outputting drive power and the braking system to perform emergency braking, it is necessary to detect the vehicle's real-time speed and determine whether the vehicle has stopped based on whether the real-time speed is zero. If the real-time speed is zero, it indicates that the vehicle is already in a stopped state, i.e., the vehicle has stopped. If the real-time speed is not zero, it indicates that the vehicle is not in a stopped state, i.e., the vehicle has not stopped, and it is necessary to continue controlling the braking system to perform emergency braking to bring the vehicle to a stop.

[0056] Step S30: If the real-time vehicle speed is zero, the vehicle is controlled to be in a parking state and a locked state.

[0057] For example, it is understood that when the real-time vehicle speed drops to zero, indicating that the vehicle is parked, the HCU will issue an electronic parking command to activate the electronic parking system, thereby parking the vehicle. This prevents the vehicle from rolling on a slope and keeps it stationary, thus avoiding accidents. The vehicle is also locked, preventing further movement to prevent further danger.

[0058] Furthermore, controlling the vehicle to be in a parking state and a locked state includes:

[0059] When it is detected that the emergency stop signal includes the emergency stop signal sent by the first emergency stop switch and the emergency stop signal sent by the second emergency stop switch, the vehicle is controlled to be in a locked state to prohibit the vehicle from moving forward and backward;

[0060] When it is detected that the emergency stop signal is the emergency stop signal sent by the first emergency stop switch, the vehicle is controlled to be in a forward locking state to prohibit the vehicle from moving forward;

[0061] When it is detected that the emergency stop signal is the emergency stop signal sent by the second emergency stop switch, the vehicle is controlled to be in a rearward locking state to prohibit the vehicle from moving backward.

[0062] For example, in this embodiment, the vehicle controller HCU can determine whether the vehicle encountered an emergency in the forward direction, the reverse direction, or both directions simultaneously through the emergency stop signal. If the vehicle controller HCU determines that only emergency stop switch 1 or emergency stop switch 2 is triggered, or both emergency stop switches 1 and 2 are triggered simultaneously, it indicates that the vehicle encountered an emergency in the forward direction, and the vehicle will be locked in the forward direction, that is, the forward gear of the vehicle will be disabled to prohibit the vehicle from moving forward. If the vehicle controller HCU determines that only emergency stop switch 3 or emergency stop switch 4 is triggered, or both emergency stop switches 3 and 4 are triggered simultaneously, it indicates that the vehicle encountered an emergency in the reverse direction, and the vehicle will be locked in the reverse direction, that is, the reverse gear of the vehicle will be disabled to prohibit the vehicle from moving backward.

[0063] If the vehicle controller HCU determines that emergency stop switch 1 and emergency stop switch 3 are triggered at the same time, or emergency stop switch 1 and emergency stop switch 4 are triggered at the same time, or emergency stop switch 2 and emergency stop switch 3 are triggered at the same time, or emergency stop switch 2 and emergency stop switch 4 are triggered at the same time, or all emergency stop switches are triggered at the same time, that is, as long as at least one emergency stop switch in the forward direction and at least one emergency stop switch in the reverse direction are triggered at the same time, it means that the vehicle has encountered an emergency in both the forward and reverse directions. At this time, the vehicle's forward and reverse directions are both locked, that is, the vehicle's forward gear and reverse gear are both controlled to be invalid, so as to prohibit the vehicle from moving forward and backward.

[0064] Furthermore, after the step of controlling the vehicle to be in a parking state and a locked state if the real-time vehicle speed is zero, the method further includes:

[0065] Determining whether a new emergency stop signal sent by the switch module is received;

[0066] If a new emergency stop signal is received from the switch module, the vehicle lock is released;

[0067] If no new emergency stop signal is received from the switch module, the vehicle remains in the locked state.

[0068] For example, in this embodiment, when the vehicle is locked, it is further determined whether the emergency situation has been resolved. Specifically, after the vehicle is locked, the vehicle will continue to monitor for new emergency stop signals to determine whether the emergency situation has been resolved. If no new emergency stop signal is received, the emergency situation has not been resolved and the vehicle lock must remain in place to prevent the vehicle from moving. If a new emergency stop signal is received, the emergency situation has been resolved and the vehicle lock can be released, allowing the vehicle to travel in the direction that resolves the emergency situation.

[0069] For example, after analyzing the on-site environment, the on-site personnel believe that the current emergency situation has been resolved. At this time, they can tap any emergency stop switch to unlock it to inform the vehicle controller HCU that the current emergency situation has been resolved, and the vehicle controller HCU will automatically unlock the vehicle, and the vehicle will resume the state of being allowed to drive; similarly, when the staff believe that the current emergency situation has been resolved after remote monitoring and analysis, they can send an emergency stop request signal to any emergency stop switch through the remote remote control or remote console. The emergency stop switch that receives the emergency stop request signal converts it into an emergency stop signal and sends it to the vehicle controller HCU to inform the vehicle controller HCU that the current emergency situation has been resolved, and the vehicle controller HCU will automatically unlock the vehicle, and the vehicle will resume the state of being allowed to drive; before the emergency stop switch is manually unlocked, the vehicle is not allowed to move and will continue to be locked.

[0070] Furthermore, if a new emergency stop signal sent by the switch module is received, the vehicle lock is released, including:

[0071] When a new emergency stop signal sent by the switch module is received, determining whether the new emergency stop signal is an emergency stop signal sent by the first emergency stop switch and / or the second emergency stop switch;

[0072] When the new emergency stop signal includes the emergency stop signal sent by the first emergency stop switch and the emergency stop signal sent by the second emergency stop switch, unlocking the vehicle so that the vehicle can move forward and backward;

[0073] When the new emergency stop signal is the emergency stop signal sent by the first emergency stop switch, releasing the forward lock of the vehicle so that the vehicle can move forward;

[0074] When the new emergency stop signal is the emergency stop signal sent by the second emergency stop switch, the rearward locking of the vehicle is released so that the vehicle can move backward.

[0075] For example, in this embodiment, in order to better control the vehicle's movement direction, the vehicle's movement direction is restricted based on whether the emergency stop switches at different locations send emergency stop signals. Specifically, after the vehicle is locked, if the vehicle controller (HCU) receives only emergency stop signals from emergency stop switches 1 and 2, it indicates that the emergency situation encountered by the vehicle in the forward direction has been resolved. At this time, the forward lock of the vehicle can be released, that is, the forward gear function can be restored to allow the vehicle to move forward. If the vehicle controller (HCU) receives only emergency stop signals from emergency stop switches 3 and 4, it indicates that the emergency situation encountered by the vehicle in the rearward direction has been resolved. At this time, the rearward lock of the vehicle can be released, that is, the reverse gear function can be restored to allow the vehicle to move backward. If the vehicle controller (HCU) receives emergency stop signals from emergency stop switches 1 to 4, it indicates that the emergency situation encountered by the vehicle in both the forward and rearward directions has been resolved. At this time, the forward and rearward locks of the vehicle can be released, that is, the forward and reverse gear functions can be restored to allow the vehicle to move forward and backward.

[0076] It can be understood that as long as one of the emergency stop switches in the forward direction does not send an emergency stop signal, it means that the emergency situation encountered by the vehicle in the forward direction has not been resolved. At this time, it is necessary to continue to control the forward lock of the vehicle to prohibit the vehicle from moving forward; similarly, as long as one of the emergency stop switches in the rear direction does not send an emergency stop signal, it means that the emergency situation encountered by the vehicle in the rear direction has not been resolved. At this time, it is necessary to continue to control the rear lock of the vehicle to prohibit the vehicle from moving backward.

[0077] It can be seen that through this application, in the process of intelligent driving debugging and operation of unmanned vehicles, when facing sudden dangerous situations, the vehicle can be automatically controlled for emergency stopping and parking by manually tapping the switch module on the vehicle, and the vehicle can be locked in time to limit the direction of movement of the vehicle, thereby avoiding accidents involving personnel or vehicles due to failure of the remote control; and in the operation process, when a pedestrian or vehicle suddenly appears in front of the vehicle through remote monitoring, an emergency stop request signal can be sent to the switch module through the remote control or remote console to achieve automatic control of emergency stopping and parking of the vehicle, and the vehicle can be locked in time to limit the direction of movement of the vehicle, thereby avoiding the occurrence of collision accidents. In addition, this application only needs to add an emergency stop switch to the whole vehicle to connect with the whole vehicle controller HCU, and then the whole vehicle controller HCU performs logical control on the service brake system, parking brake and powertrain system to achieve the emergency stop function. It is not only simple in structure and low in cost, but also effectively improves safety and user value.

[0078] In summary, the present application can not only receive remote emergency stop requests, but also realize the emergency stop function through manual switch operation on the actual vehicle, that is, through a simple switch operation, the driving power output can be stopped and the emergency brake can be stopped in the shortest time, and the parking function can be started after the vehicle stops. Before the emergency stop switch is manually unlocked, the vehicle is locked through the automatic control logic of the vehicle controller HCU, that is, the vehicle is not allowed to move to avoid danger again.
