DETAILED DESCRIPTION

[0017] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solution of the present application, rather than limitations on the technical solution of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0018] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. Embodiment 1

[0019] Figure 1 This is a flow chart of a vehicle start prompting method in the first embodiment of the present invention. This flow chart only shows the logical sequence of the method described in this embodiment. In other possible embodiments of the present invention, different methods may be used without conflict. Figure 1 The steps shown or described are accomplished in the order shown.

[0020] The vehicle start prompting method provided in this embodiment can be applied to a terminal, and can be executed by a component such as a VCU, a vehicle communication terminal, etc. that has logic processing and is connected to various driving component signals. Figure 1 The method of this implementation specifically includes the following steps: Obtain the accelerator pedal opening information and gear information; the accelerator pedal opening information and gear information can be used to determine the vehicle's parking / starting / driving / starting state, and then determine the timing of issuing a starting prompt through state analysis.

[0021] In response to the accelerator pedal opening information and the gear information both reaching a first threshold, the surrounding obstacle information corresponding to the gear information is obtained; this step is intended to improve the timing accuracy and position accuracy of the start prompt, and only when the gear state of the vehicle is determined according to the accelerator pedal opening information and the gear information, the obstacle information is determined according to the starting direction determined by the gear. It is foreseeable that if there is an obstacle in the opposite direction of the vehicle's starting direction, the start prompt cannot be triggered.

[0022] In response to the presence of obstacles in the surrounding area, the vehicle speed information is obtained; the start of the vehicle is only a short transition process. According to research, when the vehicle starts from the roadside, the driver or the intelligent driving system will maintain a lower speed before entering the lane to ensure safety. This can be used to distinguish between the starting state and the low-speed driving state.

[0023] In response to the vehicle speed being less than the vehicle speed threshold, a prompt signal is output, and the prompt signal is used to control the vehicle components to issue a start prompt to the surrounding. The vehicle components that can issue a start prompt include at least three types: 1. Sound-emitting components, such as electric horns, which use sound to prompt the surrounding vehicle that the vehicle is in the start state; 2. Light-emitting components, such as clearance lights, which use flashing lights to prompt the surrounding vehicle that the vehicle is in the start state; 3. Radio warning components, in the intelligent vehicle network system, the vehicle informs other vehicles or the road network system that the vehicle is in the start state through wireless signals.

[0024] The vehicle start prompt method provided in this embodiment first determines the vehicle state according to the accelerator pedal opening information and the gear information as a basis for subsequent steps; further determines whether the vehicle is in a start state based on the accelerator pedal opening information and the gear information, and determines the obstacle object according to the driving direction; after verifying the direction of the obstacle information, it finally determines whether the vehicle is in a state that requires a start prompt to the outside world based on the vehicle speed information; and then accurately provides a start prompt to the outside world to reduce the false alarm rate. Embodiment 2

[0025] This embodiment provides a vehicle start prompt method. This embodiment is optimized on the basis of the first embodiment to improve the technical effect and refine the technical solution. For the contents not fully described in this embodiment, please refer to the first embodiment.

[0026] The vehicle will only move when it is in the forward gear or the reverse gear. Therefore, as one embodiment, the first threshold value includes that the accelerator pedal opening is greater than 0 degrees and the gear is the forward gear or the reverse gear.

[0027] When the driver shifts the gear to forward gear or reverse gear and the accelerator pedal opening is greater than 0 degrees, it may mean that the driver is starting, while when the driver shifts the gear to parking gear or neutral gear, it is not considered as triggering the first threshold.

[0028] Embodiment 1 mentions that obtaining surrounding obstacle information corresponding to the gear information includes, in the description of this embodiment, In response to the gear position being a forward gear, obtaining obstacle information in front of the vehicle; In response to the gear position being the reverse gear, obstacle information at the rear of the vehicle is acquired.

[0029] The purpose of starting reminder is to remind people and vehicles around to keep a safe distance. Therefore, judging obstacle information based on the specific driving direction can effectively improve the accuracy of starting reminder.

[0030] After research, it was found that most drivers and intelligent driving systems will maintain a speed within 10km / h during the starting phase, and will exceed 10km / h after completing the starting turn and entering the driving lane. As one of the implementation embodiments, the speed threshold is set to 10km / h.

[0031] Embodiment 1 mentions that a prompt signal is output, and the prompt signal is used to control vehicle components to issue a starting prompt to the surroundings. As one of the embodiments, it also includes outputting a frequency voltage control instruction according to a control waveform corresponding to a pre-programmed prompt sound, and using the frequency voltage control instruction as the prompt signal. The frequency voltage control instruction is used to control the sound-emitting component to issue a starting prompt sound.

[0032] In this embodiment, a sound-emitting component is selected to emit a sound to prompt the surrounding environment. The prompt sound has a low threshold and a wide range of uses. Compared with light prompts, it can adapt to road conditions on sunny days.

[0033] As one of the embodiments, the surrounding obstacle information is obtained through a driving radar, and the accelerator pedal opening information, gear position information and vehicle speed information are obtained through an instrument.

[0034] As one embodiment, in response to the vehicle speed reaching a vehicle speed threshold, the output of the prompt signal is stopped. For example, when the vehicle speed is greater than 10 km / h, the vehicle has left the starting stage and there is no need to continue to prompt surrounding vehicles and personnel.

[0035] Compared with the first embodiment, the vehicle start prompt method provided in this embodiment refines the technical solution, clarifies and strictly limits the judgment index, and improves the accuracy of the vehicle start prompt. Embodiment 3

[0037] As one of the embodiments, the vehicle starting prompt system also includes a prompt component 2 connected to the controller 1 by an electrical signal. The prompt component 2 sends a starting prompt to the surrounding in response to the prompt signal. The power supply circuit of the prompt component 2 is coupled with the power supply circuit of the vehicle motor 3. The prompt component 2 is powered on synchronously with the vehicle motor 3, which effectively reduces the possibility of false alarm of the prompt component 2. The prompt component 2 is powered on only when the vehicle starts and the vehicle motor 3 is powered on and rotates. Only after the prompt component 2 is powered on can the prompt operation be performed according to the prompt component 2.
