Further, in step 2, when judging whether the vehicle meets the remote control function starting request, if the vehicle does not meet the vehicle starting remote control request, the vehicle-mounted communication unit feeds back the information of the failed request to the mobile phone terminal.
Further, after the voice control command is converted, the voice recognition module is displayed on the mobile phone end in a text form, and automatically sends the converted control command to the vehicle control system under the condition that no command cancel command or operation is performed within the specified waiting time. Therefore, the user operation can be reduced, and the vehicle control instruction can be directly sent after waiting for a short time, so that the remote and in-vehicle control can be realized.
Further, after the voice recognition module displays the car control instruction in a text form on the mobile phone end, the user can click the text to confirm the car control instruction and then send the car control instruction to the car control system. Thus, the user confirms and then sends the instruction, and the situation of false instruction sending can be avoided.
Further, the mobile phone car control application comprises a custom car control voice command entry, a voice command name can be custom defined through the custom car control voice command entry, the voice command name is bound with one or more car control commands, and the custom voice command is stored in a personalized voice storage library. Thus, the voice control vehicle can execute one or more functions without the need of searching function keys in the mobile phone control vehicle application by a user and directly inputting voice, is simple and convenient, has individuation, and improves the vehicle use experience of the user.
The system for controlling the vehicle by voice comprises a mobile phone, a vehicle-mounted communication unit and a vehicle control system, and is characterized in that the mobile phone has a Bluetooth connection function and is used for establishing communication connection with the vehicle-mounted communication unit through Bluetooth, a loudspeaker and a voice recognition module are further arranged in the mobile phone, the loudspeaker is used for acquiring a vehicle control instruction sent by a user, the voice recognition module is connected with the loudspeaker through a circuit and is used for converting the voice vehicle control instruction into a text mode to be displayed at a mobile phone end after receiving the voice vehicle control instruction, and the converted vehicle control instruction is sent to the vehicle control system through the vehicle-mounted communication unit; the vehicle-mounted communication unit is in communication connection with the voice recognition module and each control system of the vehicle control system, and is used for establishing Bluetooth connection with the mobile phone, judging and feeding back whether the vehicle meets the information of a remote control function starting request or not, and simultaneously, after receiving a vehicle control instruction, sending the vehicle control instruction to the vehicle control system and feeding back the execution result of the vehicle control instruction to the mobile phone.
Further, the vehicle-mounted communication unit is connected with the vehicle control system through a CAN wire.
Compared with the prior art, the method and the system for controlling the vehicle by the voice have the following advantages: 1. control vehicle is convenient: when a user has a vehicle control requirement near the vehicle, the user can realize the vehicle control by inputting a command into a microphone of the mobile phone through voice without turning over a function key on the mobile phone vehicle control software; 2. cost advantage: at present, the smart mobile phone is provided with a microphone and a Bluetooth module, and the voice control vehicle uses the mobile phone as a language conversion instruction carrier without additionally increasing the hardware configuration of the mobile phone or the vehicle.
