Abstract

An electronic control unit (ECU) of a hands-free module may be tested by an automated voice based testing tool in a first device. The tool reads test input data from an Excel input file. The tool generates simulated audible voice commands in a specified language, accent, pitch, volume or speed to test the hands-free module. The voice commands are transmitted via a speaker to a hands-free module microphone. The hands-free ECU is coupled to a CAN bus and the tool receives CAN bus information corresponding to hands-free module operations. The tool outputs test verdict information and/or CAN bus message logs as text in an Excel file.

Claims

1. A method for testing a hands-free device, the method comprising:

in an automated testing tool hosted by a first device;

reading test input from text in an input file, for testing operations of a hands-free second device, wherein said hands-free second device is communicatively coupled to a control area network (CAN) bus;

receiving by said automated testing tool, information from said CAN bus, wherein said CAN bus information corresponds to said operations of said hands-free second device responsive to the generated simulated audible voice commands; and

outputting by said automated testing tool, text in an output file comprising one or both of;

verdict information corresponding to said testing said operations of said hands-free second device; and

all or a portion of said information received from said CAN bus.

2. The method of claim 1, wherein said text in said test input file indicates said one or more simulated audible voice commands and one or more expected responses by said hands-free second device.

3. The method of claim 1, wherein said one or more simulated audible voice commands for said testing operations of said hands-free second device are generated by said automated testing tool based on text to speech logic and comprise one or more of a specified:

language;

pronunciation;

regional accent;

volume;

pitch; and

speed.

4. The method of claim 1 further comprising, in said automated testing tool, comparing expected responses from said text in said read test input file to said information received from said CAN bus to determine said verdict information.

5. The method of claim 1, wherein said first device and said second device are communicatively coupled via a first mobile phone and a second mobile phone and said automated testing tool is operable to receive said information from said CAN bus corresponding to:

a call initiated in said first mobile phone to said second mobile phone by said generated one or more simulated audible voice commands, or

a call initiated automatically by said automated testing tool in said second mobile phone to said first mobile phone based on said read test input.

6. The method of claim 1, wherein said generating one or more simulated audible voice commands comprises transmitting said simulated audible voice commands from said first device via a speaker positioned to be sensed by a microphone communicatively coupled to said hands-free second device.

7. The method of claim 1, wherein said hands-free second device comprises an electronic control unit (ECU) for a vehicle and said operations of said hands-free second device includes communicating messages onto said CAN bus after one or more of:

receiving an audible voice command;

reorganizing said voice command;

comparing said voice command to a programmed grammar;

receiving a command via a wireless interface;

receiving a command via an optical interface; and

receiving a command via a wire line interface.

8. The method of claim 1, wherein said first device and said hands free second device are communicatively coupled by a control area network (CAN) message processor, and wherein said automated testing tool is operable to, one or both of:

enable audible voice command operations in said hands-free second device by transmitting a command to said hands-free second device via said CAN message processor; and

receive said CAN bus information from said hands-free second device via said CAN message processor.

9. A system for testing a hands-free device, the system comprising one or more circuits or processors in a first device, said one or more circuits or processors being operable to:

in an automated testing tool hosted by said first device;

read test input from text in an input file, for testing operations of a hands-free second device, wherein said hands-free second device is communicatively coupled to a control area network (CAN) bus;

generate one or more simulated audible voice commands, for said testing operations of said hands-free second device, based on said read test input;

receive by said automated testing tool, information from said CAN bus, wherein said CAN bus information corresponds to said operations of said hands-free second device responsive to the generated simulated audible voice commands; and

output by said automated testing tool, text in an output file comprising one or both of;

verdict information corresponding to said testing said operations of said hands-free second device; and

all or a portion of said information received from said CAN bus.

10. The system of claim 9, wherein said text in said test input file indicates said one or more simulated audible voice commands and one or more expected responses by said hands-free second device.

11. The system of claim 9, wherein said one or more simulated audible voice commands for said testing operations of said hands-free second device are generated by said automated testing tool based on text to speech logic and comprise one or more of a specified:

language;

pronunciation;

regional accent;

volume;

pitch; and
