Referring to fig. 2, a control method of an adaptive cruise system switch according to a second embodiment of the present invention is shown, and specifically includes steps S11 to S51:

the control method is applied to a control system of a switch of the adaptive cruise system. The control system comprises a voice processing module 12, an ACC control module, a conversion module 22, a judgment module 32 and a feedback module 32.

The voice processing module 12 includes a voice collecting unit, a voice recognizing unit, and a semantic analyzing unit.

Step S11, acquiring sound information of a driver, wherein the sound information comprises a wake-up phrase;

Specifically, when a driver starts a vehicle and runs, the voice acquisition unit can receive sound information in the vehicle in real time and judge whether the sound information is the sound of the current driver, if the sound information is the sound of the driver, the sound information is analyzed by the semantic analysis module, and if the sound information is not the sound of the driver, awakening is failed.

The voice information comprises a wake-up phrase, and the semantic analysis module analyzes the wake-up phrase in the voice information and judges whether the real-time analyzed wake-up phrase is matched with a preset wake-up phrase. If the ACC voice control system is matched with the ACC voice control system, triggering a wake-up instruction to enable the ACC voice control system; and if not, ignoring the piece of voice information and analyzing the next piece of voice information.

Step S21, collecting the voice signal of the driver and judging whether the voice signal is matched with a preset voice signal;

and if so, converting the sound signal into a corresponding voice command.

Specifically, the voice acquisition unit can receive sound information in a vehicle in real time, the voice recognition unit recognizes whether the sound signal is a sound signal of a driver or not, and filters the sound signal which is not the driver, the semantic analysis unit analyzes the sound signal of the driver and judges whether the received sound signal is matched with a preset sound signal (preset sound signal) or not, and if the received sound signal is matched with the preset sound signal, the real-time received sound signal is converted into a corresponding voice instruction; and if not, filtering the sound signal and analyzing the next sound signal.

More specifically, in the present embodiment, the voice command is a fixed phrase, such as "turn on adaptive cruise" or "turn on ACC", "activate ACC", "accelerate to xx", "decelerate to xx", "resume ACC", "cancel ACC", "turn off ACC", "increase following distance", "decrease following distance", and the like. In order to operate the ACC by other drivers in the vehicle, when a new driver operates the ACC every time, the voice processing module 12 learns and memorizes the voice of the driver, and in the learning process, the voice recognition unit memorizes the voice of the driver, and when the voice acquisition unit acquires the voice signal, the voice recognition unit can accurately and efficiently recognize the voice signal of the driver.

Step S31, converting the voice command into a corresponding ACC control command and transmitting the ACC control command to an ACC control module;

specifically, after the driver starts the ACC voice control system through the spoken wake-up command, the voice processing module 12 can acquire the voice command of the driver in real time and immediately transmit the voice command to the converting module 22, the converting module 22 converts the real-time received voice command into a corresponding ACC control command and transmits the ACC control command to the ACC control module in real time, so as to convert the driver's demand from a voice signal into an electric signal, thereby avoiding the process of manual operation of the driver.

Step S41, judging whether the ACC control instruction can be executed according to the current running state of the vehicle;

if yes, generating a corresponding ACC driving instruction according to the ACC control instruction through the ACC control module, controlling the vehicle according to the ACC driving instruction, and sending ACC state information;

If the received ACC command is judged to be an executable command, converting the real-time received ACC control command into a corresponding ACC running command, controlling the state of the vehicle (such as the vehicle speed, the distance between the vehicle and the front vehicle) according to the ACC running command, and transmitting ACC state information;

Step S51, receiving the ACC state information after control and transmitting the ACC state information to the human-computer interaction module, wherein the human-computer interaction module comprises a display prompt unit and a voice prompt unit;

Specifically, in this embodiment, the human-computer interaction module includes a display prompt unit and a voice prompt unit, and when the ACC state information after control is received, the ACC state information can be fed back to the driver through the display prompt unit or the voice prompt unit, where the display prompt unit may be set as a central control screen or a dashboard, and the voice prompt unit is set as a speaker. The ACC state information is converted into character information and indicator light information through the display prompting unit and fed back to the driver, or the ACC state information is converted into voice information through the voice prompting unit and fed back to the driver.

In this embodiment, it should be noted that the human-computer interaction module mainly performs display feedback and voice feedback on the ACC operating state, the set cruising speed, the set following time interval, the actual distance of the leading vehicle, and the like. When the driver controls the ACC through voice, and the ACC cannot be executed or cannot be immediately executed, besides the ACC is fed back to the driver through text display, the human-computer interaction module can also carry out voice broadcast and directly feed back to the driver. On the other hand, if the ACC cannot control the vehicle to be kept in a safe state, the human-computer interaction module prompts the driver to take over the vehicle in time through sound; meanwhile, the human-computer interaction module can also carry out corresponding image reminding.

In the present embodiment, the ACC state information includes an actual vehicle speed of the current vehicle, a set cruising vehicle speed, a set following time interval, an actual following distance, an ACC operation state, and the like.
