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.

TECHNOLOGIES FOR EFFICIENT RELIABLE COMPUTE OPERATIONS FOR MISSION CRITICAL APPLICATIONS
Technologies for efficiently providing reliable compute operations for mission critical applications include a reliability management system. The reliability management system includes circuitry configured to obtain conclusion data indicative of a conclusion made by each of two or fewer compute devices of a host system. The conclusion data from each compute device pertains to the same operation. Additionally, the circuitry is configured to identify whether an error has occurred in the operation of each compute device, determine, in response to a determination that an error has occurred, a severity of the error, and cause the host system to perform a responsive action as a function of the determined severity of the error.
LIDAR sensor frost detection
A vehicle system includes a processor programmed to receive sensor signals from a LIDAR sensor. The processor estimates frost accumulation on the LIDAR sensor from the sensor signals and compares the estimated frost accumulation to a predetermined threshold. The processor further prevents a host vehicle from operating in an autonomous mode if the estimated frost accumulation exceeds the predetermined threshold.
Starting control device for electrically driven vehicle
A starting control device is provided for an electrically driven vehicle having an electric motor and an internal combustion engine as drive sources and a transmission shifts and transmits an output of the electric motor to a drive wheel. The starting control device is configured to suppress an abrupt increase in the rotation of the electric motor at the time of an EV start of the vehicle from a released state of a starting dog clutch. In the electrically driven vehicle, an EV start is carried out by transmitting the output of the first motor/generator (MG1) to the drive wheel via a starting dog clutch that is meshingly engaged. The output of the first motor/generator is limited until the starting dog clutch comes into a meshed state in which the transmission transmits drive power at the time of start from a released state of the starting dog clutch.

Autonomous vehicle diagnostic system
An on-board diagnostic system for an autonomous vehicle can receive diagnostic data from any number of AV systems of the AV. For each AV system the on-board diagnostic system can determine whether the diagnostic data indicates that the AV system is operating nominally. In response to determining a fault condition of an AV system, the on-board diagnostic system can initiate a procedure associated with the respective AV system to resolve the fault condition.
Control strategy for an electric machine in a vehicle
A vehicle is provided including an electric machine and at least one controller. The controller, or controllers, are configured to, in response to a reset of the at least one controller while a speed of the vehicle is greater than a threshold value, provide a current command to the electric machine in accordance with calibration values calculated prior to the reset such that inoperability of the electric machine due to the reset is less than one second.

Vehicle electronic control apparatus
A first monitoring control circuit unit monitors controlling operation of an engine control unit (ECU); when the occurrence frequency of an abnormality becomes the same as or larger than a predetermined threshold value, a first storage circuit stores that occurrence frequency and a first cutoff circuit de-energizes an intake valve opening degree control motor for an air-intake throttle so as to set the intake valve opening degree to a fixed intake valve opening degree; a second monitoring control means monitors controlling operation of a transmission control unit (TCU); when the occurrence frequency of an abnormality becomes the same as or larger than a predetermined threshold value, a second storage circuit stores that occurrence frequency and a second cutoff circuit de-energizes a gear-shifting electromagnet valve so as to set the transmission ratio to a fixed transmission ratio.
