  • 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.
