The present disclosure is related to a vehicle control apparatus, a vehicle control system and a vehicle control method thereof. In particular, the present disclosure provides a vehicle control apparatus comprising: a communication device for communicating with a remote control center; and a controller configured to determine a state of each of one or more component devices related to the vehicle performing an autonomous driving, and to generate and output a determination result signal, determine a driving mode of the vehicle as one of a remote driving mode, an emergency action mode, or an autonomous driving maintenance mode based on the determination result signal, and control the vehicle according to the driving mode determined by the driving mode determiner.

An engine ECU executes a control routine including steps of performing output variation control for periodically varying the output of an engine, if control of the engine is not being stopped, at the time of a communication abnormality, and a predetermined time elapses from the time of occurrence of the communication abnormality, and a step of performing fuel-cut control, when the engine speed falls outside a predetermined range.

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.

The purpose of the present invention is to provide a system in which the reliability of an automatic driving system can be excellently complemented by a different control system while the automatic driving system is effectively used. The vehicle control device outputs to a drive device one of a first control signal generated on the basis of automatic driving control information, and a second control signal generated on the basis of the relative information between a vehicle and a surrounding object. If an abnormality is detected in the automatic driving control information, the second control signal is output to the drive device in place of the first control signal.

While coolant is used to cool a motor inverter and a generator inverter included in a power drive unit configured to invert power between a battery and a motor/generator in both directions, an EV travel mode and a power generation travel mode are switched according to detection values from sensors in an electrically driven vehicle and including a switching device temperature sensor for a switching device of the inverters and a coolant temperature sensor, thereby controlling the vehicle. A failure of the coolant temperature sensor is detected according to a detection value from the coolant temperature sensor, and, in the EV travel mode, a detection value detected by the switching device temperature sensor for the switching device of the generator inverter is set as a detection value of a temperature of the coolant when the failure of the coolant temperature sensor is detected.

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. The vehicle is equipped with, as traveling modes, a normal mode, and an eco-mode having a larger regenerative braking force than the normal mode obtained such that rotational energy of the wheels is converted into electrical energy. A controller stops the internal combustion engine and switches from the normal mode to the eco-mode when detecting at least an abnormality in the internal combustion engine during traveling of the vehicle.

A system for controlling a failure of an environment-friendly vehicle is provided to which a highway driving pilot (HDP) system is applied. The system includes a vehicle control unit (VCU) controller that operates a driving motor, an integrated electric booster (IEB) controller that operates IEB for controlling a brake of the environment-friendly vehicle and generate a request to the VCU controller for regenerative braking, and an HDP controller that calculates a required deceleration of the environment-friendly vehicle based on the situation around the environment-friendly vehicle, determined through cognitive control sensors applied to the environment-friendly vehicle. The HDP controller transmits the required deceleration to the IEB controller. At least one of regenerative braking of the driving motor or braking through the brake is performed based on a type of a fault message output by the IEB controller or a failure in communication between the HDP controller and the IEB controller.

An automotive arithmetic system includes a main arithmetic device that determines a target motion of a motor vehicle so that the motor vehicle travel on a route generated based on a vehicle external environment estimated using deep learning based on an output from a vehicle external information acquisition device; and a backup arithmetic device that determines a backup target motion for causing the motor vehicle to travel on a travel route which is generated based on the output from the vehicle external information acquisition device and which the traveling motor vehicle takes until the motor vehicle stops at a stop position that satisfies a preset criterion. The automotive arithmetic system outputs a backup control signal to actuators in preference to a control signal when the main arithmetic device fails.

A method for controlling autonomous driving in a vehicle capable of the autonomous driving may include collecting vehicle travel status information and system status information during the autonomous driving, sensing a failure based on the system status information, identifying normally controllable actuators when sensing the failure, determining a risk degree corresponding to the sensed failure based on the normally controllable actuator information and the vehicle travel status information, determining a safety state based on normally controllable actuator information and the risk degree, and determining a failure safety strategy corresponding to the safety state.

A redundant hardware and software architecture can be designed to enable vehicles to be operated in an autonomous mode while improving the reliability and/or safety of such vehicles. A system for redundant architecture can include a set of at least two redundant sensors coupled to a vehicle and configured to provide timestamped sensor data to each of a plurality of computing unit (CU) computers. The CU computers can process the sensor data simultaneously based on at least a time value indicative of an absolute time or a relative time and based on the timestamped sensor data. The CU computers provide to a vehicle control unit (VCU) computer at least two sets of outputs configured to instruct a plurality of devices in a vehicle and cause the vehicle to be driven.
