Document Type and Number:
Japanese Patent JP2018090185
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular control device that can set reaction force characteristics of an accelerator pedal on the basis of a protagonist suitable for a driving situation, so that operability of the accelerator pedal by a driver can be improved.SOLUTION: A vehicular control device 1 comprises a three-dimensional map M which has forward characteristics FA and FB and return characteristics FC and FD and has F-S characteristics of an accelerator pedal 3 set, and a reaction force setting part 24 that sets reaction force of the accelerator pedal 3 on the basis of the three-dimensional map M. The vehicular control device further comprises a muscle activity estimating part 23 that estimates whether a protagonist of a lower limb of a human body to be set as a subject of action is either a single articular muscle or a biarticular muscle on the basis of a driving situation. The reaction force estimating part 24, when the protagonist to be set as the subject of action is estimated to be the single articular muscle, corrects the forward characteristic FB in a reaction force decreasing direction, and when the protagonist is estimated to be the biarticular muscle, corrects the forward characteristic FB in a reaction force increasing direction.SELECTED DRAWING: Figure 1
