Title:
VEHICLE CONTROL DEVICE AND VEHICLE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/048085
Kind Code:
A1
Abstract:
In the present invention, a longitudinal acceleration computing unit is provided with an LPF, an HPF, and an adder unit. The LPF acquires longitudinal acceleration of a vehicle, detected by a longitudinal acceleration sensor provided in the vehicle, and removes high-frequency components from the acquired longitudinal acceleration. The HPF acquires longitudinal acceleration of the vehicle estimated on the basis of the vehicle engine torque and brake-fluid pressure, and removes low-frequency components from the acquired longitudinal acceleration. The adder unit finds, on the basis of the high-frequency-component-eliminated longitudinal acceleration, in which the high-frequency components have been removed by the LPF, and the low-frequency-component-eliminated longitudinal acceleration, in which the low-frequency components have been removed by the HPF, a composite longitudinal acceleration that serves as the longitudinal acceleration of the vehicle.
