Abstract: A vehicle control system configured to reduce physical stress on a driver to operate an accelerator pedal without reducing acceleration feel. The vehicle control system selects a first driving force property if an estimated stress on an ankle is less than a threshold value, and selects a second driving force property if the estimated stress on the ankle is greater than the threshold value to reduce the stress on the ankle. When the second driving force property is selected, a target driving force is reduced less than a target driving force calculated based on the first driving force property. In this case, the vehicle control system reduces a difference between: a ratio of acceleration to a pedal force given that the first driving force property is selected; and a ratio of acceleration to the pedal force given that the second driving force property is selected.

Abstract: A hybrid vehicle in which a running mode can be appropriately shifted without making a driver feel uncomfortable or feel a sense of slowness. A hybrid vehicle includes an engine, a first motor, a second motor, and a clutch that selectively transmits power between the engine and drive wheels. A controller shifts a running mode to the parallel hybrid vehicle mode in a case of accelerating the hybrid vehicle in the electric vehicle mode, if the drive force is greater than a maximum drive force generatable in the electric vehicle mode, and also greater than a required additional drive force as a variable corresponding to a running resistance against the hybrid vehicle running on a predetermined running road at a predetermined vehicle speed by a predetermined drive force that is set in advance based on the vehicle speed and the drive force.

Abstract: A drive force control system for a vehicle having a motor and a battery that allows a driver to sense a satisfactory acceleration even if an output torque of a motor is restricted. The drive force control system comprises a controller that calculates an upper limit acceleration of the vehicle based on an upper limit power to be supplied from the battery to the motor. The controller sets a reference jerk as the required jerk when the upper limit acceleration is equal to or greater than the target acceleration, and sets a corrected jerk that is greater than the reference jerk as the required jerk when the upper limit acceleration is less than the target acceleration.

Abstract: A control system for a hybrid vehicle configured to smoothly engage an engagement device while reducing a collision noise of the engagement device. The control system is configured to apply torque to a set of teeth on one half of the engagement device to shift a phase of the set of teeth in the event of teeth interference. After the completion of engagement of the engagement device, the control system further applies torque to the set of teeth on one half of the engagement device to reduce backlash between the set of teeth on one half of the engagement device and a set of teeth on the other half of the engagement device.

Abstract: A shift control device for establishing a desired gear stage promptly while reducing a shock, during propulsion while disengaging all of engagement devices of a transmission. The shift control system compares a target stage set based on an operating data to an interim stage set based on the operating data immediately before the target stage is set. If the target stage is lower than the initial stage the engagement devices are engaged to establish the target stage without establishing the initial stage.

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.

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.

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.
