[0002] With the advancement and development of science and technology, people's lives are becoming more and more convenient and intelligent. Therefore, people's requirements for the performance of vehicles are gradually increasing.

[0003] In terms of emergency starting of the vehicle, the traditional emergency starting system needs to determine whether the battery voltage is higher than the calibrated voltage, T15 is powered on, the brake signal, the engine speed is lower than the calibrated speed, there is no stop request from the engine stop module, IMMO, transmission status, cab tilt status, transmission system status, handbrake switch status, intake heating status, engine synchronization signal, vehicle speed, etc. The procedure is cumbersome and of low practicality.

[0005] However, the coverage of this technical solution is limited. It is only applicable to automatic transmission vehicles and only solves the problem of gear signal error. It does not fully consider other starting conditions. The utilization rate and practicality of emergency starting are not high, and it can only meet the vehicle starting needs in specific scenarios.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0028] In terms of emergency starting of the vehicle, the traditional emergency starting system needs to determine that the battery voltage is higher than the calibrated voltage, T15 is powered on (i.e., the ECU is powered on and woken up), the brake signal, the engine speed is lower than the calibrated speed, there is no stop request from the engine stop module, the anti-theft control unit IMMO status, the gearbox status, the cab tilt status, the transmission system status, the handbrake switch status, the intake heating status, the engine synchronization signal, the vehicle speed, etc. The procedure is cumbersome and of low practicality.

[0029] At the same time, the following improvement scheme exists in the prior art: after triggering the emergency start mode, it is only necessary to make a comparison with the emergency start condition, without considering the gear signal of the vehicle, which solves the problem that the traditional automatic transmission vehicle cannot start the vehicle due to the loss or unreliability of the gear signal. The above technical scheme can meet the vehicle starting requirements in specific scenarios without increasing the hardware cost according to different vehicle usage scenarios, that is, different current vehicle conditions, and enhance the robustness and practicality of the system; at the same time, based on the working principle of the engine, multiple approaches are proposed, that is, the vehicle starting control method under different emergency start conditions, taking into account the functional requirements of the engine control unit ECU and the transmission control unit TCU, coordinating the relationship between the two, and realizing safe and effective vehicle starting in normal and emergency situations.

[0030] like Figure 1 As shown, an embodiment of the present application provides a vehicle emergency starting system, comprising:

[0031] The start button detection module 2 is connected to the main control module 1 and is used to detect the duration of the T50 power-on (i.e., engine power-on start) signal;

[0032] The emergency start condition detection module 3 is connected to the main control module 1 and is used to detect whether the vehicle meets the emergency start condition;

[0033] The starter control module 4 is connected to the main control module 1 and can start the vehicle in an emergency when the electrical signal at T15 lasts for a first preset time and the vehicle meets the emergency start condition.

[0034] Specifically, the T15 power-on signal lasting for the first preset time can be considered as the driver pressing the start button for a long time exceeding the first preset time. After the driver presses the start button for a long time exceeding the first preset time, the emergency start mode is triggered, and the emergency start mode trigger signal is sent to the main control module 1. After receiving the emergency start mode trigger signal, the main control module 1 controls the emergency start condition detection module 3 to detect the emergency start condition. After the vehicle emergency start condition is met, the main control module 1 controls the starter control module 4 to start the vehicle in an emergency. The problem of failure to start when the start condition status signal is lost or unreliable in the traditional vehicle start control is solved, and the vehicle is started with the driver's judgment as the first priority to meet the driving needs; compared with the traditional emergency start system, the robustness of the start system is increased, which can greatly improve the success rate of the vehicle emergency start; and compared with the above-mentioned improvement scheme, this scheme has a wide range of applicability and improves the utilization rate and practicality of emergency start.

[0035] It should be noted that the present application does not limit the first preset time length, which can be selected from 5s to 10s.

[0036] As an optional implementation, the emergency start condition detection module 3 includes: a power module detection submodule, connected to the power module, for detecting the T15 power-on signal; a brake signal submodule, for detecting whether the brake signal is normal; and a gear status submodule, for detecting whether the gear is in a preset state.

[0037] As an optional implementation, the emergency start conditions include: T15 is powered on, the brake signal is normal, and the gear is in a preset state.

[0038] As an optional implementation manner, the normal brake signal includes: a braking state; the gear position is in a preset state includes: the gear position is in a neutral state.

[0039] Specifically, the emergency start condition only determines T15 power-on, brake signal, and gear status. There is no need to consider other starting condition signals of the vehicle that are lost, unreliable, or cannot be started due to other restrictions, such as the vehicle cannot be started due to gear signal errors, battery voltage signal errors, etc.

[0040] As an optional implementation, it also includes an electronic handbrake module, which is connected to the main control module 1. When the electrical signal on T15 lasts for the first preset time length and the brake signal state is not a braking state, the main control module 1 controls the electronic handbrake module to switch the brake signal state to a braking state.

[0041] As an optional implementation, it also includes an automatic shift module connected to the main control module 1. When the power-on signal at T15 lasts for a first preset time and the gear position is not in a neutral state, the main control module 1 controls the automatic shift module to switch the gear position to a neutral state.

[0042] Specifically, this solution can be applied to vehicles with automatic transmission and electronic handbrakes. When the power-on signal at T15 continues for the first preset time period and the brake signal state is not in the braking state, the main control module 1 controls the electronic handbrake module to switch the brake signal state to the braking state; when the power-on signal at T15 continues for the first preset time period and the gear position is not in the neutral state, the main control module 1 controls the automatic transmission module to switch the gear position to the neutral state.

[0043] As an optional implementation, it also includes a communication module connected to the main control module 1.

[0044] As an optional implementation, when the power-on signal at T15 lasts for a first preset time and the vehicle does not meet the emergency start conditions, the communication module can communicate with the vehicle system to control the vehicle system to output a signal indicating that the vehicle does not meet the emergency start conditions.

[0045] As an optional embodiment, the vehicle system includes a display module, which is configured to display a signal indicating that the vehicle does not meet the emergency start condition when the electrical signal at T15 lasts for a first preset time period and the vehicle does not meet the emergency start condition.

[0046] As an optional implementation, the vehicle system includes a voice broadcast module, which is configured to output a signal indicating that the vehicle does not meet the emergency start condition when the power-on signal at T15 lasts for a first preset time period and the vehicle does not meet the emergency start condition.

[0047] Specifically, for vehicles that are not equipped with automatic handbrakes and automatic transmissions, the main control module 1 can also connect and communicate with the vehicle system through the CAN bus communication module, trigger an alarm and display the reason for not meeting the starting requirements on the control screen. The system can also give voice reminders through the voice broadcast module to ensure that the driver can notice the problem in time. The scope of application of the vehicle emergency starting system is expanded and the practicality of the vehicle emergency starting system is improved.
