A method for operating a lane guidance system involves determining a time period from the time of a request from the lane guidance system to a vehicle user to touch the steering handle until the occurrence of a sensor signal caused by a touch of the steering handle in the sensor region and comparing it with a predetermined time window. An activation option of the lane guidance system is blocked in the event that the determined time duration is greater than the predetermined time window. In the event of a first request to touch the steering handle after an idle state, an activation option of the lane guidance system is disabled until a subsequent idle state.

A vehicle control system that ensures a sufficient distance to empty in the event of a failure of a clutch for changing an operating mode of a vehicle. The control system is configured to: determine a reduction in performance of the clutch based on a value of a parameter for determining a performance of the clutch; and select the operating mode in which a distance to empty is longer and inhibit to actuate the engagement device, when a reduction in performance of the engagement device is determined.

A driving control method of an autonomous vehicle with an integrated control apparatus, which is configured to be operated by a user in a manual driving mode of the autonomous vehicle, includes: an autonomous driving determining operation of determining whether autonomous driving can be continuously performed based on surroundings of the autonomous vehicle; a first determining operation of determining a breakdown of a vehicle driving part in a state where an operation of the autonomous vehicle is stopped from the autonomous driving upon determining that the autonomous driving cannot be performed; and controlling the vehicle to be maintained in a stopped state until the autonomous vehicle is turned off upon determining the breakdown of the autonomous vehicle driving part.

A method for operating an autonomously driving vehicle that is connected to a central computer unit via a communication connection for exchanging data. During the autonomous driving mode, a request to take over a driving task is emitted to a vehicle user when at least one takeover condition is fulfilled. The takeover condition is fulfilled when it is established that the communication connection to the central computer unit is disrupted on a route portion that exceeds a predetermined length and on which the vehicle is located or which the vehicle is approaching.

A control target for a control device (10) is a vehicle drive device (1) including a rotating electrical machine (MG), and the control device (10) includes: an actual rotational speed obtaining part (14) that obtains an actual rotational speed (Nm) which is an actual rotational speed of the rotating electrical machine (MG); an actual torque obtaining part (15) that obtains actual torque (Tm) which is actual torque of the rotating electrical machine (MG); and a determining part (16) that determines a state of the rotating electrical machine (MG). The determining part (16) determines that the state of the rotating electrical machine (MG) is a negative torque abnormality, when the actual torque (Tm) has a negative value smaller than a torque threshold value (THt) set based on a relationship between the actual rotational speed (Nm) and target torque (Tmt) of the rotating electrical machine (MG).

Method and apparatus are disclosed for mitigating issues for a vehicle executing a remote vehicle operation, wherein there is a communication delay between the vehicle and a remote computing device providing control. An example vehicle includes a communication system, an autonomy unit for performing a remote vehicle operation, and a processor. The processor is configured to receive a remote vehicle operation control signal via the communication system from a remote computing device. The processor is also configured to determine a delay corresponding to the control signal. And the processor is further configured to modify the remote vehicle operation responsive to determining that the delay rises above a delay threshold at a threshold rate.

A vehicle control apparatus can continue a control function against abnormality in operation of an arithmetic processor and in the power supply voltage, and capable of improving reliability. Where there is no abnormality, the autonomous travel control unit and an auxiliary control unit calculate control instruction values for automatic driving control, and validate a CAN communication circuit of autonomous travel control units while invalidating a CAN communication circuit of the auxiliary control unit. Where an abnormality occurs in the autonomous travel control unit and not the auxiliary control unit, the CAN communication circuit of the autonomous travel control unit is invalidated and the CAN communication circuit of the auxiliary control unit is validated. Where the auxiliary control unit has no abnormality when the autonomous travel control unit has an abnormality during automatic driving control thereof, seamless automatic driving control with substantially no time lag continues.

A method for operating an autonomous vehicle. The method includes the transmission of status data to a processing unit, which is independent of the autonomous vehicle, using a wireless communications link. The method furthermore includes monitoring of the function of the autonomous vehicle by the independent processing unit while taking the status data into account, and when a malfunction of the autonomous vehicle is detected, the independent processing unit determines target data for guiding the autonomous vehicle to a stopping position. The target data are transmitted to the autonomous vehicle, and the autonomous vehicle is guided to the stopping position with the aid of the target data. A position of the autonomous vehicle is determined using signals from the wireless communications link and is taken into account when determining the target data.

An information processing device includes: a processor; and a memory including at least one set of instructions that, when executed by the processor, causes the processor to perform operations. The operations include: obtaining incident information about an incident of a cyberattack that occurred in a vehicle; obtaining first vehicle information about a state of a first vehicle; storing, in the memory, the incident information and the first vehicle information; determining a risk level of a vehicle function of the first vehicle, based on a degree of matching between the incident information and the first vehicle information stored in the memory, the vehicle function of the first vehicle being one among one or more vehicle functions of the first vehicle; generating a function restriction command for restricting the vehicle function, when the risk level is higher than a first criterion; and outputting the function restriction command.

A method for producing an active short circuit condition in an electric motor of a hybrid electric vehicle including a traction battery, an inverter having switches in communication with the electric motor and the traction battery, and an inverter controller in communication with the inverter and configured to generate driver signals to operate the switches to produce three-phase alternating current for the electric motor to drive a vehicle propulsion system or to produce direct current for charging the traction battery. The method includes determining an electric motor speed threshold, wherein the electric motor speed threshold is continuously variable, comparing a monitored speed to the speed threshold, and generating, in response to the monitored speed exceeding the speed threshold, driver signals to operate the switches to produce an active short circuit condition in the electric motor to prevent overcharging of the traction battery.
