Title:
VEHICLE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2021146857
Kind Code:
A
Abstract:
To provide a vehicle control device capable of performing highly accurate control as compared with a case where control is performed using a measurement result stored at the time of measuring pneumatic pressure of a tire, without using a transceiver that detects pneumatic pressure and sends a detection signal.SOLUTION: A control device 4 has: storage means 41 for storing a measured value when pneumatic pressure of a tire of a four-wheel drive vehicle 1 is measured together with a state quantity of an influencing factor that affects the pneumatic pressure of the tire at the time of the measurement; control amount calculation means 42 for calculating a control amount of a traveling device related to the traveling of the vehicle; estimation means 43 for estimating pneumatic pressure of the tire at the time of controlling the traveling device based on the measured value stored by the storage means 41 and the difference between the state quantity of the influencing factor stored by the storage means 41 and the state quantity of the influencing factor at the time of controlling the traveling device; and correction means 44 for correcting the control amount of the traveling device according to the pneumatic pressure of the tire estimated by the estimation means 43.SELECTED DRAWING: Figure 3
