  • Patent number: 9902393
    Abstract: A vehicle control system is provided to ensure acceleration response while improving energy efficiency in an autonomous vehicle in which an operating mode is selected from an autonomous mode and a manual mode. A switching device is disposed between a motor and drive wheels to switch a driving mode between a direct drive mode and a differential drive mode. A controller executes a motor-idling control to keep a speed of the motor to a standby speed during propulsion in a motor-standby mode. The controller is configured to select a first standby speed of a motor idling control in a case that the vehicle is propelled in the manual mode, and to select a second standby speed that is lower than the first standby speed in a case that the vehicle is propelled in the autonomous mode.

  • Patent number: 9873434
    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.

  • Patent number: 9533669
    Abstract: A vehicle control device is a vehicle control device for a vehicle capable of coasting, in which when there is no acceleration or deceleration request to the vehicle while traveling, power transmission between an engine and drive wheels is cut off and the vehicle is allowed to travel by inertia, wherein in a state in which there is no acceleration or deceleration request to the vehicle while traveling and power is transmitted between the engine and the drive wheels, whether or not to implement the coasting is determined by comparing a required deceleration rate Dt which is estimated as a deceleration rate to be later required of the vehicle and a coasting deceleration rate Dn which is estimated as a deceleration rate during the coasting.

  • Patent number: 9506558
    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.

  • Publication number: 20160312885
    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.

  • Publication number: 20160304124
    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.
