摘要： A diagonal equal-hop heterogeneous composite redundancy domain architecture of an intelligent vehicle, comprising: a central gateway, and ADAS domain controller, a vehicle-mounted audio and video domain controller, a vehicle chassis domain controller, and an energy domain controller. The central gateway is respectively communicatively connected to the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller, and the energy domain controller, such that the central gateway, the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller, and the energy domain controller form a star connection topological structure; and the ADAS domain controller, the vehicle-mounted audio and video domain controller, the vehicle chassis domain controller, and the energy domain controller form an annular connection topological structure.

摘要： Embodiments of this present disclosure may include a system with a first power converter and a control system. The first power converter may supply a first output power to a first backplane at least sometimes concurrent to a second power converter supplying a second output power to a second backplane. The control system may be electrically coupled to the first backplane and the second backplane. The control system may balance a first electrical property and a second electrical property provided to each of one or more load components electrically coupled to the first backplane and the second backplane.

摘要： This disclosure presents an assisted driving vehicle system, including autonomous, semi-autonomous, and technology assisted vehicles, that can share sensor data among two or more controllers. A sensor can have one communication channel to a controller, thereby saving cabling and circuitry costs. The data from the sensor can be sent from one controller to another controller to enable redundancy and backup in case of a system failure. Sensor data from more than one sensor can be aggregated at one controller prior to the aggregated sensor data being communicated to another controller thereby saving bandwidth and reducing transmission times. The sharing of sensor data can be enabled through the use of a sensor data distributor, such as a converter, repeater, or a serializer/deserializer set located as part of the controller and communicatively coupled to another such device in another controller using a data interface communication channel.

摘要： A servo system includes multiple servo drivers that are operable in cooperation with each other and are each drivable independently with highest possible control accuracy. The servo system includes a first servo driver that drives a first motor, a second servo driver connected to the first servo driver with a first signal line to drive a second motor, and a host device connected to the first and second servo drivers with a second signal line. The second servo driver switches, in response to a switch command from the host device, between a first mode in which the second servo driver drives the second motor in accordance with a first control command from the first servo driver and a second mode in which the second servo driver drives the second motor in accordance with a second control command from the host device.

摘要： A crash sensor device may include multiple sensor components positioned along one or more data paths to a communication interface of the crash sensor device. The crash sensor device may include a test control unit. The test control unit may receive a test command from an electronic control unit during operation of a vehicle. The test control unit may perform a test of one or more sensor components, of the multiple sensor components, during operation of the vehicle based on the test command. The test control unit may output a test result to the electronic control unit based on performing the test.

摘要： The present invention is capable of realizing normal control of a control device and safe operation of a control target. In the present invention, an automatic control unit 10 generates a control output that is output to a control target in response to an input 1. A safety verification control unit 20 is configured to verify safety of the control output at a plurality of verification levels, and controls the control output on the basis of the verification result. A verification level selection unit manages the state related to the normality of the automatic control unit 10, and selects the verification level of the safety of the control output in the safety verification control unit 20 in accordance with the state.

摘要： There is provided a control device that prevents the occurrence of an abnormality in control using artificial intelligence in the case where an abnormality occurs in another terminal that performs the control using the artificial intelligence. A control means (a first control unit) performs the control using artificial intelligence. The control means (second control unit) performs control different from the artificial intelligence. A control switching unit (a switching determination means, a switch) is configured to, when another terminal having the control means (the first control unit) is normal, cause the own control means (the first control unit) to perform the control using artificial intelligence, and when an abnormality occurs in another terminal having the control means (the first control unit), cause the control means (the second control unit) to perform the control different from artificial intelligence.

摘要： A system and method for detecting a failure in a redundant signal path during operation of the redundant path is disclosed. A test signal is sequentially injected into each signal path while an input signal is conducted by the other signal path not receiving the test signal. The test signal is selected at a frequency to verify operation of a filter connected in series along each path. A processor generates the test signal, injects the test signal at the input of the filter, and receives the output of the filter. The processor then generates a frequency response of the filter in each signal path as a function of the output from the filter and of the original test signal. The frequency response obtained along each of the redundant signal paths is compared to each other to detect a failure of one of the filters present along the respective signal paths.
