  • Patent number: 11807237
    Abstract: A vehicle control system configured to control deceleration of a vehicle properly according to a driver's intention in one-pedal mode. In the one-pedal mode, a controller controls deceleration of the vehicle based on a deceleration level set in accordance with a speed of the vehicle. If the brake pedal is manipulated to decelerate the vehicle while the vehicle is operated in the one-pedal mode and an operating amount of an accelerator pedal falls within the decelerating range, the controller updates the deceleration level based on an operation of the brake pedal.

  • Publication number: 20220274615
    Abstract: A drive force control system controls acceleration of a vehicle accurately in line with an operation of an accelerator pedal to improve an acceleration feel. A controller calculates a corrected target acceleration when a required acceleration is large and an operating speed of the accelerator pedal is fast, and converts the corrected target acceleration into a target driving force to propel the vehicle so as to achieve the corrected target acceleration by generating the target driving force.

  • 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.

  • Publication number: 20200309042
    Abstract: A driving force control apparatus for a vehicle includes an operation amount detection unit; a vehicle speed detection unit; and an electronic control unit. The electronic control unit is configured to determine, when a vehicle speed is lower than a predetermined vehicle speed, a target driving force in a case where an operation amount of an accelerator pedal is in a predetermined range, based on a first provisional target driving force; and determine, when the vehicle speed is equal to or higher than the predetermined vehicle speed, the target driving force in the case where the operation amount of the accelerator pedal is in the predetermined range, based on a second provisional target driving force.

  • Patent number: 9194312
    Abstract: A control device of a vehicle drive device includes an engine having a supercharger and an automatic transmission outputting power of the engine to drive wheels. When an upshift of the automatic transmission is performed by executing an acceleration operation, if a progress status of a supercharging pressure increase in a supercharger pressure increasing process by the supercharger is a status in an initial period of the increasing process, a supercharging pressure increase degree before start of an inertia phase of the upshift is made smaller than a supercharging pressure increase degree after a predetermined timing subsequent to the start of the inertia phase, while if the progress status of the supercharging pressure increase is a status in an ending period of the increasing process, the supercharging pressure increase degree before the start of the inertia phase is made larger than the supercharging pressure increase degree after the predetermined timing.
