Abstract
A test system that conducts a test of a test subject that is a vehicle or a part thereof that includes an electronic control device, comprises a drive test device for conducting a drive test of the test subject, an automatic driving robot that drives the test subject, and a signal control unit that is connected to the test subject by wire or wirelessly and that transmits, to the electronic control device, a test signal for evaluating the electronic control device.
Claims10
A test system that conducts a test of a test subject that is a vehicle or a part thereof equipped with an electronic control device, comprising:
- a drive test device for conducting a drive test of the test subject;
- an automatic driving robot that drives the test subject;
- a test management unit configured to bring the test subject into a predetermined state defined by at least a vehicle speed and a running load applied by the drive test device, in which a test for evaluating a cyber security function of the electronic control device can be initiated, by controlling at least one of the drive test device or the automatic driving robot;
- a signal control unit that is connected to the test subject by wire or wirelessly and that, while the test subject is maintained in the predetermined state, transmits to the electronic control device a cyber security test signal for evaluating a cyber security function of the electronic control device, the cyber security test signal simulating an unauthorized control input under the predetermined state;
- a correct data storage unit that stores correct data in which the cyber security test signal is associated with a response signal expected to be output from the electronic control device when the cyber security test signal is transmitted under the predetermined state, and with an expected behavior of the test subject under the predetermined state;
- and
- a judgment unit configured to judge whether the response signal output from the electronic control device or behavior information of the test subject under the running load applied by the drive test device agree with the correct data.
A test method for conducting a test of a test subject that is a vehicle or a part thereof that includes an electronic control device, the test method comprising:
- controlling the test subject via at least one of a drive test device for conducting a drive test of the test subject or an automatic driving robot that drives the test subject to bring the test subject into a predetermined state defined by at least a vehicle speed and a running load applied by the drive test device;
- and
- while the test subject is maintained in the predetermined state, transmitting, to the electronic control device, a cyber security test signal for evaluating a cyber security function of the electronic control device the cyber security test signal simulating an unauthorized control input under the predetermined state;
- storing correct data in which the cyber security test signal is associated with a response signal expected to be output from the electronic control device when the cyber security test signal is transmitted under the predetermined state, and with an expected behavior of the test subject under the predetermined state;
- and
- determining whether a response signal output from the electronic control device or behavior information of the test subject under the running load applied by the drive test device agree with the correct data.
A non-transitory computer readable medium on which is stored a program for a test system that conducts a test of a test subject that is a vehicle or a part thereof that includes an electronic control device, the program when executed by a computer causes the computer to function as:
- at least one of a drive test device control unit that controls a drive test device for conducting a drive test of the test subject and an automatic driving robot control unit that controls an automatic driving robot that drives the test subject to bring the test subject into a predetermined state defined by at least a vehicle speed and a running load applied by the drive test device;
- and
- a signal control unit that, while the test subject is maintained in the predetermined state, transmits, to the electronic control device, a cyber security test signal for evaluating a cyber security function of the electronic control device by wired communication or wireless communication, cyber security test signal simulating an unauthorized control input under the predetermined state;
- a correct data storage unit that stores correct data in which the cyber security test signal is associated with a response signal expected to be output from the electronic control device when the cyber security test signal is transmitted under the predetermined state, and with an expected behavior of the test subject under the predetermined state;
- and
- a judgment unit configured to determine whether a response signal output from the electronic control device or behavior information of the test subject under the running load applied by the drive test device agree with the correct data.
