  • Patent number: 11048288
    Abstract: An operation device in which in-vehicle devices are controlled in accordance with a rotation angle of an input unit operated by a manual operation of a driver, which includes a commander rotatable about a rotation shaft, a rotation angular speed calculation unit that detects a rotation angular speed of the commander, a motor that gives an operation reaction force for each predetermined rotation angle of the commander, and an ECU that controls the operation reaction force given by the motor, wherein the ECU changes the operation reaction force in accordance with the rotation angular speed detected by the rotation angular speed calculation unit.

  • Publication number: 20180370357
    Abstract: A vehicle control device is provided, which includes a depression amount detector configured to detect a depression amount of an accelerator pedal, a processor configured to execute a reaction force setting module to set a reaction force of the accelerator pedal based on a detection result of the depression amount detector, a reaction force applying part configured to apply the reaction force to the accelerator pedal based on a setting result of the reaction force setting module, and an operation amount detector configured to detect an operation amount of a driver's foot on the accelerator pedal. The reaction force setting module sets a reaction force value of the accelerator pedal for a depression characteristic and a counter-depression characteristic. The reaction force setting module includes a reaction force correcting module configured to reduce the reaction force value of the counter-depression characteristic as the detected operation amount increases.
