Abstract: When anomalous vehicle actions occur in a vehicle multiple times, it is determined whether each action data is included in a series of action data sets that are closely related mutually or an irrelevant independent action data set. When it is included in the series of action data sets, the ECUs record the series of action data sets in respective own memories according to a predetermined recording order. In contrast, when it is included in the independent action data set, an earliest ECU that is earliest in the recording order records the action data by overwriting its own memory. In this case, the earliest ECU transmits an instruction to other ECUs to delete all past action data that are recorded in own memories of the other ECUs.

Abstract: A vehicle steering device (1) has a steering actuator (14) for steerable wheels (5) to be steered according to operation of a steering member (2), a transmission mechanism (18) including cables (22, 23), a connection mechanism (19) for allowing and interrupting mechanical connection between the steering member (2) and the wheels (5), and control unit (9). When the steering actuator (14) is normal, the control unit (9) causes the connection mechanism (19) to release mechanical connection between the steering member (2) and the wheels (5) and drives and controls the steering actuator (14) according to operation of the steering member (2). The control unit (9) includes a fail detecting section (29) for detecting, when the steering actuator (14) is normal, a fail of the transmission mechanism (18) based on a load on the steering actuator (14).

Abstract: Methods and systems are provided for assessing understeer for a vehicle having at least one rear wheel and at least one front wheel. Rear wheel speeds are measured from the rear wheels, and front wheel speeds are measured for the front wheels. A determination is made as to the understeer of the vehicle using a comparison of the front wheel speeds and the rear wheel speeds.

Abstract: A method is provided for operating a sensor of a vehicle. The sensor is configured to detect objects within a detection range and the method includes, but is not limited to detecting an object with the sensor. In addition, a position of the object is determined with data from the sensor. Furthermore, position data emitted by the object is received with a receiving apparatus of the vehicle and the position of the object is determined with the position data. Moreover, the position determined with the sensor is compared with the position of the object and comparative data is determined and an automatic adjustment of the sensor and/or output of a message inside the vehicle is made depending on the comparative data.

Abstract: An electric control apparatus for a vehicle is provided. The apparatus comprises at least two microcomputers, an external monitoring unit, and an internal monitoring means. The two microcomputers are composed of a first microcomputer and a second microcomputer, The first microcomputer is assigned to controlling travel functions of a vehicle. The external monitoring unit monitors whether or not the first microcomputer is in a normal operation and is placed outside the first and second microcomputers. The internal monitoring means monitors whether or not the first microcomputer is in a normal operation and is within the first microcomputer.

Abstract: The effects of IMU gyro and accelerometer bias errors are significantly reduced in accordance with the present teachings by a system or method for commanding an IMU or vehicle through a series of preprogrammed maneuvers. The maneuvers can be designed to minimize the effects of other gyro errors including scale factor errors, nonlinearities, cross coupling/misalignment, and scale factor asymmetries. A sample maneuver is provided which demonstrates performance based on a sequence of roll and yaw maneuvers resulting in zero build up of error at the end of a maneuver cycle period as a result of these errors. Modification of the system involves the addition of control logic to determine the maneuver period, maneuver rate, and vehicle orientation. No additional hardware beyond possible fuel required to perform the maneuver is required.

Abstract: A method, apparatus and computer program product are provided to not only predict an impending fault, but also to avoid the occurrence of the fault such that continued operations are permitted with a reduced likelihood of the occurrence of the fault. In this regard, a plurality of features are provided to at least one model, such as a random forest classification model. The plurality of features include features representative of at least one prior operational sequence as well as features representative of at least one upcoming operational sequence. The plurality of features are then processed with at least one model to determine a likelihood of a fault during the upcoming operational sequence. The method also alters the characteristics of the upcoming operational sequence without requiring maintenance of the equipment to thereby permit the upcoming operational sequence to be conducted with a reduced likelihood of the fault.

Abstract: A vehicle system comprises multiple processors and a communication system adapted to run real-time vehicle applications. The system adds new devices, identifies data generated by the new device and identifies another device that can input or output the data. The vehicle system also includes a dynamic configuration system configured to operate on the multiple processors and store critical information about the applications running on the multiple processors. The configuration manager automatically detects an application failure and initiates a reconfiguration process. The configuration manager then downloads from memory the previously stored critical data associated with the failed application and initiates a reboot operation for the failed application.

Abstract: One or more embodiments include systems and methods for regulating control of a vehicle infotainment system. In one embodiment, a vehicle computing system includes a user interface which has one or more output components and one or more input components. Software executing in memory of the vehicle computing system may be programmed with rules to reduce driver distraction such as preventing inputs or outputs during vehicle operation. Inputs may be intercepted from the one or more input components of the user interface. Additionally or alternatively, outputs may be intercepted to the output components of the user interface. The intercepted inputs or intercepted outputs may be evaluated for one or more violations based on the rules. If the one or more violations are detected, the inputs or outputs may be prevented during vehicle operation.
