Abstract
A vehicle control device includes: a unit that acquires a first transmission torque transmitted in a first state in which a control pressure is controlled to a first pressure value, and a second transmission torque transmitted in a second state in which the control pressure is controlled to a second pressure value; a control unit including a storage unit that stores control data including data indicating a relationship between a friction coefficient and a surface pressure. The control unit calculates a first friction coefficient based on the data and the first pressure value, calculates a second friction coefficient based on the data and the second pressure value, calculates an estimated value of the touch point pressure based on the first and second pressure values, the first and second transmission torques, the first and second friction coefficients to control data based on the estimated value.
