  • Patent number: 10059203
    Abstract: An acceleration pedal reaction force control device imparts to a driver a sensation (feeling) of an appropriate reaction force in accordance for example with an intention of/operation performed by the driver. The acceleration pedal reaction force control device is configured such that when a stepping amount on the acceleration pedal has become equal to or exceeded a threshold stepping amount, whether a reaction force increase rate at which a base reaction force increases to a target reaction force with the threshold stepping amount should be made variable or a reaction force increase amount (enhancing reaction force) for causing the base reaction force to increase to the target reaction force with the threshold stepping amount should be made variable can be set. Thereby, a sensation (feeling) of an appropriate reaction force can be imparted to a driver in accordance for example with an intention of/an operation performed by the driver.

  • Patent number: 9365112
    Abstract: An accelerator-pedal-counterforce control device for a vehicle, wherein a counterforce control means sets a value obtained by multiplying a prescribed quantity by a constant-speed position as a counterforce-increase position. The counterforce-increase position is a position of the accelerator pedal at which the counterforce on the accelerator pedal is increased from the base counterforce. The constant-speed position is a position of the accelerator pedal at which constant travel at the current vehicle speed is possible. The prescribed quantity is set as a value for achieving forward-rear acceleration according to each vehicle speed.

  • Patent number: 9145130
    Abstract: A vehicle travel control device sets a first travel state in which a vehicle is caused to travel only by an internal combustion engine and a second travel state in which the vehicle is caused to travel by the internal combustion engine and an electric motor. The first travel state and the second travel state are switched to each other on the basis of vehicle information including the depression amount of an accelerator pedal. When a remaining electric power amount detected by a remaining electric power amount detection unit is less than a first predetermined value, a reaction force application unit sets a first accelerator pedal depression amount threshold at which the reaction force of the accelerator pedal is increased just before the switching from the first travel state to the second travel state.

  • Patent number: 9068516
    Abstract: A reaction force control unit calculates a driver's requested output and then estimates a maximum output that can be generated by an engine in a current cylinder deactivation operation. Next, the reaction force control unit calculates a difference between the maximum output and the requested output as an output difference and then determines whether the output difference has reached a predetermined reaction force start threshold value, and if the determination result is Yes, the reaction force control unit estimates a number of to-be-reactivated cylinders on the basis of the output difference and the current cylinder deactivation operation state. Subsequently, the reaction force control unit sets a target reaction force on the basis of the output difference and the number of to-be-reactivated cylinders, and outputs drive current to a reaction force actuator.
