  • Patent number: 11347255
    Abstract: A reaction force control system configured to control a reaction force applied to a pedal without reducing an operational feeling. A controller reduces a reaction force applied to the pedal mildly from a second reaction force to a first reaction force at a rate D upon satisfaction of a predetermined condition. The rate D is determined based on a depression of the pedal, a pedal force applied to the pedal, an elapsed time, or a predetermined function.

  • Publication number: 20210387523
    Abstract: A reaction force control system for a pedal that is configured to stably operate a vehicle in which an operating mode can be shifted between normal and one-pedal modes, without requiring a complicated operation, and without disturbing a driver. An operating mode is selected from a one-pedal mode in which a drive force and a brake force are controlled by manipulating an accelerator pedal, and a normal mode in which drive force is controlled by manipulating the accelerator pedal, and the brake force is controlled by manipulating the brake pedal. Reaction force applied to the accelerator pedal is increased for a predetermined period of time when shifting from one of the operating modes to the other one, and thereafter the reaction force is adjusted in accordance with a position of the accelerator pedal in the other one of the operating modes.

  • Publication number: 20200324753
    Abstract: A control system for vehicles that controls drive force and acceleration smoothly without causing a shock, in response to an operation of an accelerator pedal. A hysteresis is set between an input value and an output value of angle of the accelerator pedal. The hysteresis includes a deadband and an asymptotic range. The output value is not changed significantly with respect to a change in the input value if an angle of the accelerator pedal is changed within the deadband, and the output value is changed continuously with respect to a change in the input value based on a predetermined function if an angle of the accelerator pedal is changed within the asymptotic range.

  • Patent number: 10584791
    Abstract: A speed change control system configured to allow a driver to promptly sense a response to an accelerating operation. A reference index value that the driver senses an acceleration response is calculated based on acceleration of a vehicle. If the reference index value is smaller than a first reference index value at which the driver is allowed to sense the acceleration response, a downshift point is lowered to a first drive force.

  • Patent number: 10486706
    Abstract: A driving force control system for a vehicle configured to control a driving force based on the accelerating operation by the driver. The vehicle comprises a drive unit including a prime mover and a transmission, an accelerator device; and a controller. The controller is configured to: calculate an operating amount of the accelerator device; calculate an operating speed of the accelerator device; calculate a target jerk; and control an output torque of the drive unit based on the target jerk, when the operating amount is smaller than a predetermined amount, and the operating speed is slower than a predetermined speed.

  • Patent number: 9160928
    Abstract: An image capture apparatus includes an output unit, a first horizon maintaining assistance processing unit, and a second horizon maintaining assistance processing unit. The output unit sequentially outputs and displays captured images on a display screen. The first horizon maintaining assistance processing unit and the second horizon maintaining assistance processing unit determines whether it is difficult to identify a capturing condition of the captured image that is sequentially outputted and displayed by the output unit by way of the output unit. Furthermore, in a case in which it is determined that it is difficult to identify the capturing condition in the captured image by way of visual recognition of the display screen, the first horizon maintaining assistance processing unit and the second horizon maintaining assistance processing unit display a guidance relating to the capturing condition on the display screen or executes correction processing on the captured image.

  • Patent number: 8502882
    Abstract: In an image pick-up apparatus 1, when an instruction of setting white balance is given by user's manual operation, a central region of a picked up image is set and further the central region of image is divided into plural regions of image. In each of the plural regions of image, RGB components are detected, and gain values of R and B components are calculated, which make these R and B components equivalent to G component. Further, when a variance of colors of the plural regions of image is less than a predetermined threshold value, it is determined that a picture is taken with a color pattern set at the center of viewing angle, an average of gain values set for the plural regions of image is calculated and the average is supplied to a gain controlling unit 41 to be applied to an image signal.

  • Patent number: 6590192
    Abstract: A microwave oven determines an appropriate time to stop heating even if multiple food items are placed in the heating chamber. After any position on the bottom surface of the microwave oven reaches 75 deg C., a search is made for any other position having a temperature of at least 70 deg C. If such a position is detected, heating is concentrated on that position until it reaches 75 deg C. When all food-containing positions in the microwave oven have reached a temperature of at least 75 deg C., the heating operation performed by the magnetron is stopped.

  • Patent number: 6563097
    Abstract: A microwave oven heats all food in an appropriate manner even if food items are simultaneously placed at multiple locations in a heating chamber. An auxiliary antenna is periodically stopped at an orientation corresponding to a position where a lowest temperature was detected at the start of the heating operation. Between stopped periods, the auxiliary antenna is rotated for a period to apply heat evenly to all food in the oven. If multiple low-temperature points are detected, the central position of these multiple low-temperature points is used for applying concentrated heat.
