Abstract: A vehicle control system configured to suppress engine noise in an autonomous mode is provided. An operating mode of the vehicle can be switched between a manual mode in which a driving force and a braking force of the vehicle are controlled by a manual operation and an autonomous mode in which the driving force and the braking force of the vehicle are controlled autonomously. The vehicle control system is configured to shift an upshifting point for reducing a speed ratio of a transmission to a low speed side in the autonomous mode, in comparison with the upshifting point set in the manual mode.

Abstract: A vehicle control system configured to ensure running stability of a vehicle even if a vehicle weight is heavy is provided. The vehicle control system determines a travel locus of the vehicle within a planned route. If the vehicle tows another vehicle, or if a weight of the vehicle is heavier than a predetermined threshold value, the control system alters the travel locus of the vehicle in such a manner that a turning radius of the vehicle is increased.

Abstract: A vehicle control system to prevent a vehicle stopped in the autonomous mode from being started undesirably is provided. The vehicle control system is configured to select an operating mode from an autonomous mode and a manual mode, and to select a drive range from a drivable range and a non-drivable range. A controller is configured to detect a fact that a door is opened, that a door lock is unlocked, or that a seatbelt is unfastened. If at least any of those facts is detected, the controller shifts the drive range to the non-drivable range or shifts the operating mode to the manual mode.

Abstract: A vehicle control system configured to adjust a vehicle behavior to the behavior expected by the driver in autonomous mode is provided. The vehicle control system determines target values of the driving force, the braking force, and the steering angle based on manual operations of an accelerator, a brake and the steering device in the autonomous mode. A controller corrects a control parameter including a vehicle speed, a distance from a forerunning vehicle, an acceleration and a travelling locus based on the manual operation executed in the autonomous mode.

Abstract: When a drive shaft (37) is driven while the operation of an engine (36) is stopped, the rotation of an input-side rotor (28) is restricted by the engagement of a brake. Further, on the basis of the temperature Temp_SR of a brush (96) acquired by a temperature sensor (97), the distribution of torque Tcoup acting between the input-side rotor (28) and the first output-side rotor (18) and torque Tmg acting between the stator (16) and the second output-side rotor (19) is controlled. Consequently, drive performance when the drive shaft (37) is driven while the operation of the engine (36) is stopped is improved while local overheating of a slip ring (95) is prevented.

Abstract: A vehicle control system to reduce shocks under an autonomous mode is provided. The vehicle control system is configured to select an operating mode of a vehicle from a manual mode in which a driving force and a braking force are controlled manually by a driver, and an autonomous mode in which the driving force and the braking force are controlled autonomously. A controller is configured to execute a fuel cut-off control, and a threshold selected under the autonomous mode is set in such a manner as to terminate the fuel cut-off control earlier than under the manual mode.

Abstract: The present disclosure relates to a control apparatus for a vehicle. The vehicle includes an engine, and a transmission that is coupled to the engine. The control apparatus includes an electronic control unit (ECU). The ECU is configured to change a speed ratio of the transmission without an operation by a driver when an automatic operation mode is selected, and change the speed ratio of the transmission as a result of an operation by the driver when a manual operation mode is selected. The automatic operation mode and the manual operation mode are selected by the driver. The ECU executes shifting limit control based on selection of the automatic operation mode. The shifting limit control is control for reducing a shock resulting from the changing of the speed ratio of the transmission.

Abstract: A vehicle control system is provided to propel a vehicle in a stabilized manner when switching an operating mode from an autonomous mode to a manual mode. The vehicle control system is configured to: control an operating condition of the vehicle; determine an execution of steering operation by the driver; and continue the autonomous control of the steering wheel if the steering wheel cannot be operated by the driver when the autonomous control of the vehicle is interrupted by a manual operation of a driver and hence the operating mode is switched from the autonomous mode to the manual mode.

Abstract: A vehicle control system is provided to improve energy efficiency of a vehicle that can be operated not only manually but also autonomously. The vehicle control system is configured to deliver oil to an oil requiring site in a first feeding amount under the manual mode, and to deliver oil to the oil requiring site in a second feeding amount that is smaller than the first feeding amount during propulsion under the autonomous mode in line with a travel plan. When a required amount of oil delivered to the oil requiring site is expected to be increased based on the travel plan under the autonomous mode, the controller increases an oil feeding amount to the oil requiring site from the second feeding amount.

The vehicle control system is configured to select an operating mode from an autonomous mode and a manual mode, and to select a drive range from a drivable range and a non-drivable range. A controller is configured to detect a fact that a door is opened, that a door lock is unlocked, or that a seatbelt is unfastened. If at least any of those facts is detected, the controller shifts the drive range to the non-drivable range or shifts the operating mode to the manual mode.
