Intelligent recording of errant vehicle behaviors
Systems, methods and apparatus of recordation of vehicle data associated with errant vehicle behavior. For example, a vehicle includes: sensors configured to generate sensor data; control elements configured to generate control signals to be applied to the vehicle in response to user interactions with the control elements; electronic control units configured to provide status data in operations of the electronic control units; and a data storage device. The data storage device is configured to receive input data including the sensor data, the control signals and the status data, store the input data in a cyclic way in an input partition over time, generate a classification of errant behavior based on the input data and using an artificial neural network, and preserve a portion of the input data associated with the classification of errant behavior.
Vehicle control device
The present invention realizes a vehicle control device that, even when power characteristics of a power generation device and a power transmission device changes, senses degradation of vehicle components, corrects a drive instruction to the power transmission device, and is thereby capable of stabilizing vehicle behavior over a long term. The present invention, in a predetermined vehicle environment state, measures fluctuation in drive power and acceleration in a transient region by using vehicle behavior sensors 4, performs comparison with a reference fluctuation, and thereby senses degradation of vehicle components. The drive instruction to the transmission 16-side is corrected in accordance with the degradation of vehicle components that is sensed. Thus, it is possible to stabilize vehicle behavior (performance) over a long term even when, during automated driving, the power characteristics of the drive power source and the transmission 16 change due to factors such as time degradation of vehicle components.

Transmit-side misbehavior condition management
In various embodiments, a vehicle-to-everything (V2X) processing device detecting a misbehavior condition in a system of the vehicle, and prevent the vehicle from sending a V2X message related to the detected misbehavior condition in response to detecting the misbehavior condition in the system of the vehicle. In some embodiments, the V2X processing device may receive information from a plurality of information sources of the vehicle, and may detect the misbehavior condition in the system of the vehicle by performing a cross-check of information received from the plurality of information sources of the vehicle to detect an inconsistency within the received information.

Method for dynamic context-based distribution of software in a vehicle control system, and a control system
Technologies and techniques for dynamic, context-based distribution of program codes in a control system in a vehicle. The control system includes numerous control units. The allocation of the program codes to the corresponding control units in the control system takes place using a global placement chart. The global placement chart is calculated on a computer, which may be located outside the control system. The data from the global placement chart are sent to the control system. Other aspects include an at least partially autonomous motor vehicle that has a control system for executing dynamic, context-based distribution of program codes.

VEHICLE PUMP CONDITION RESPONSE METHOD AND ASSEMBLY
An exemplary pump condition response method includes, in response to a pump condition, operating an engine to discontinue or prevent a first stop-start cycle during a drive cycle. The method permitting a second stop-start cycle during the drive cycle.
Hybrid vehicle
In the case where a throttle valve has a sticking abnormality, a hybrid vehicle performs failsafe operation (limp home mode) with fixing the throttle valve to an opener position (S100) and sets a restoration diagnosis cooling water temperature T1 such as to decrease with a decrease in state of charge SOC of a battery (S120). When cooling water temperature Tw of the engine becomes equal to or higher than the restoration diagnosis cooling water temperature T1, the hybrid vehicle performs sticking restoration diagnosis to determine whether the throttle valve is restored from the sticking abnormality (S150). This allows for earlier diagnosis of whether the throttle valve is restored from the sticking abnormality at the lower state of charge SOC of the battery and enables the hybrid vehicle to return to normal operation at an earlier time. As a result, this ensures the more adequate sticking restoration diagnosis.
