A vehicular driving assist system includes a forward viewing camera, a forward sensing non-vision sensor, and an electronic control unit (ECU) disposed at a vehicle equipped with the vehicular driving assist system. Captured image data is transferred from the camera to the ECU and processed at the ECU and captured sensor data is transferred from the non-vision sensor to the ECU and processed at the ECU. An object forward of the equipped vehicle is detected via processing at the ECU of transferred image data and via processing at the ECU of transferred sensor data. The ECU determines a difference between detection of the object via processing at the ECU of transferred image data and detection of the object via processing at the ECU of transferred sensor data. The ECU disables at least part of a driving assist function based on the determined difference being greater than a threshold level.

A vehicle control system includes a central ECU configured to calculate target outputs of actuators, and relay devices each disposed in a communication path between the central ECU and a corresponding actuator among the actuators. The plurality of relay devices includes a specific relay device configured transfer a control signal from the central ECU only to a fixed actuator that is an actuator not related to driving control, braking control, and steering control of a vehicle. The specific relay device is configured to output, to the fixed actuator coupled to the specific relay device, one of a signal for setting the fixed actuator in an operating state or a signal for setting the fixed actuator in a non-operating state, in response to detection of an abnormality in the central ECU. The specific relay device does not have a function of diagnosing an abnormality in the specific relay device.

A vehicle control device controls a vehicle including a drive motor connected to a rotation shaft of wheels, a battery that supplies electricity to the drive motor, and an internal combustion engine connected to the drive motor.

A system for producing an active short circuit in an electric motor of a hybrid electric vehicle having a traction battery includes an inverter to be provided in communication with the motor and battery, and an inverter controller to generate driver signals to operate inverter switches to produce three-phase AC for the motor or to produce DC for battery charging. In response to motor speed exceeding a threshold, the controller is configured to generate driver signals to operate the inverter switches to produce an active short circuit in the motor to prevent battery overcharging. A processor and electric circuit are each configured to independently generate an active short circuit control signal operative to effectuate generation of the driver signals, the active short circuit produced based on an active short circuit control signal from the electric circuit in an absence of an active short circuit control signal from the processor.

Embodiments disclose systems and methods to operate an autonomous vehicle. In one embodiment, a system (an electronic controlled unit (ECU) of an autonomous driving vehicle (ADV)) receives a command, the command sent by an autonomous driving system (ADS) of the ADV. The system determines a communication state between the ECU and the ADS based on a state machine corresponding to a timing of the received command. If the communication state is of a first state, the system operates the ADV based on the received command. If the communication state is of a second state, the system releases a throttle of the ADV. If the communication state is of a third state, the system releases a throttle of the ADV and brakes using a first threshold of acceleration.

A control device for controlling the operation of an internal combustion engine and of an electrical machine in a hybrid drive assembly, which permits a mechanical coupling of the engine and the machine in a drive train. An engine control part controls the internal combustion engine and an electrical machine control part controls the electrical machine. A monitoring part monitors proper operation of the control parts and, in the event of a malfunction, takes over a control function within a reaction time span. An engine false-start prevention part detects a transition of the internal combustion engine from stopped to running and, in the event of such a transition, checks if a proper start of the internal combustion engine was requested within a predefined past time span in order to prevent a fuel supply release and/or an ignition release if such a start was not requested.

A drivetrain has at least one electric drive machine configured for driving a motor vehicle, a drivable rear motor vehicle axle for transmitting drive forces of the electric drive machine to a roadway surface, and a vehicle transmission which has at least one transmission ratio stage and which is configured for transmitting drive forces in the direction of the drivable rear motor vehicle axle. The transmission ratio stage can, in at least one operating mode of the drivetrain, be engaged by a transmission control unit. The vehicle transmission can, from the transmission ratio stage, be shifted by the transmission control unit into a neutral position in which a transmission output shaft is freely rotatable relative to a transmission input shaft. For control of the electric drive machine, an electric motor control unit is provided, wherein the electric drive machine is, by way of the electric motor control unit, operable at least in a motor operating mode and in a neutral mode, in which the electric drive machine is rotatable in a manner free from torque.
