A control system for a hybrid vehicle configured to start an engine promptly during propulsion in an electric vehicle mode. Electric power generation resulting from cranking the engine by a first motor is greater in the first electric vehicle mode compared to a second electric vehicle mode. A controller that is configured to determines whether an acceptable input power to an electric storage unit is smaller than a threshold value. If the acceptable input power to the electric storage unit is smaller than the threshold value, selection of the first electric vehicle mode is inhibited.

The cloud includes a server and a storage device. The storage device includes a road surface information map. When a first sampling distance is equal to or longer than a first distance threshold, the server performs re-sampling to interpolate data in such a manner that sampling positions located at a second sampling distance and unsprung mass member displacements of the respective sampling positions exist so as to produce re-sampled data-for-producing-map. The server stores a sub-sectional unsprung mass displacement in a storage area corresponding to a sub-section of the road surface information map, based on the re-sampled data-for-producing-map.

A vehicle control apparatus to be applied to a vehicle includes a driver state-value detection processor, a road-surface-state detection processor, a threshold setting processor, a dangerous-driving determination processor, and a determination threshold changing processor. The driver state-value detection processor detects a state value of a driver who drives the vehicle. The road-surface-state detection processor detects a road-surface state of a road on which the vehicle is traveling. The threshold setting processor decides, based on the state value, one or more determination thresholds of a state to be determined as occurrence of dangerous driving. The dangerous-driving determination processor determines that the dangerous driving is occurring in a case where the state value is present within a range outside any of the one or more determination thresholds for a predetermined time period or more. The determination threshold changing processor changes the one or more determination thresholds based on the road-surface state.

A control system for a vehicle capable of traveling in first and second traveling states is provided. The second traveling state requires an operation related to traveling by a passenger more than the first traveling state. The system changes, based on a traveling situation of the vehicle, an upper limit speed at which the vehicle can travel in the first traveling state. The system performs notification to the passenger of a request for a predetermined operation at a timing when a traveling speed of the vehicle reaches a predetermined speed when switching from the first traveling state to the second traveling state. A difference between the upper limit speed and the predetermined speed is increased in a case where the upper limit speed is high compared to a case where the upper limit speed is low.

It has been difficult to appropriately determine the abnormality of a drive source due to the influence of variation in driving operation amount and operation state of a vehicle. In this regard, an in-vehicle control device 217 includes: a requested torque calculation unit 100 which calculates a requested torque on the basis of a driving state of a vehicle; a requested torque change amount calculation unit which calculates the amount of change in requested torque per unit time as a requested torque change amount; an estimated generation torque calculation unit 111 which calculates estimated generation torque estimated as being generated by an engine 201; an estimated generation torque change amount calculation unit which calculates the amount of change in estimated generation torque per unit time as an estimated generation torque change amount; and an abnormality detection unit 112 which detects an abnormality of the engine 201 on the basis of the integrated value of a difference between the requested torque change amount and the estimated generation torque change amount, and outputs abnormality determination for the engine 201.

A control device for a vehicle capable of switching between an automated driving mode in which driving force of a vehicle having a transmission is automatically controlled and a manual driving mode in which the driving force of the vehicle is controlled on the basis of a driver's operation on the vehicle includes: an operation element to which the driver's operation is input; and a travel control unit that outputs a command value for selecting a gear range of the transmission. The travel control unit selects which of ordinary gear change control and gear change restricting control is to be performed on the basis of an operation performed on the operation element when there is an automated driving release request in which the automated driving mode is released and the automated driving mode is switched to the manual driving mode during traveling of the vehicle in the automated driving mode.

A method for determining the direction of travel of a vehicle comprises providing a first sensor for measuring a longitudinal acceleration of the vehicle and at least one second sensor for establishing the rotational movement of a wheel of the vehicle, An acceleration signal containing acceleration information from the first sensor is received by the system. The acceleration signal is filtered resulting in a modified acceleration signal. The direction of travel of the vehicle is determined based on the modified acceleration signal and based on the output signal of the second sensor.

This disclosure provides a vehicle control device, a vehicle control method, and a recording medium. The vehicle control device according to one aspect of an embodiment includes a recognition unit that recognizes an object in a periphery of the own vehicle, a road information acquisition unit that acquires road information in the periphery of the own vehicle, and an alarm control unit that causes an alarm device to give an alarm when the object recognized by the recognition unit exists in a predetermined region set with reference to a position of the own vehicle, in which the alarm control unit does not give the alarm regarding the object when at least part of the object existing in the predetermined region recognized by the recognition unit exists outside a road from a boundary the road where the own vehicle acquired by the road information acquisition unit exists.

A system and method for determining object-wise situational awareness that includes receiving data associated with a driving scene of a vehicle, an eye gaze of a driver of the vehicle, and alerts that are provided to the driver of the vehicle. The system and method also includes analyzing the data and extracting features associated with dynamic objects located within the driving scene, the eye gaze of the driver of the vehicle, and the alerts provided to the driver of the vehicle. The system and method additionally includes determining a level of situational awareness of the driver with respect to the each of the dynamic objects based on the features. The system and method further includes communicating control signals to electronically control at least one component of the vehicle based on the situational awareness of the driver.
