Patent number: 11472382Abstract: A control device is applied to a vehicle that has a braking device configured to be able to adjust the braking force applied to the vehicle. The control device has a stopping braking force imparting unit that controls the braking device in order to apply a stopping braking force to the vehicle, as a minimum value of the braking force required to keep the vehicle stopped. The control device also has a deviation quantity deriving unit that derives a deviation quantity between a state quantity of the vehicle obtained when the stopping braking force is applied to the vehicle by the stopping braking force imparting unit and an ideal value of the state quantity of the vehicle. The control device also has a stopping braking force updating unit that updates the stopping braking force on the basis of the deviation quantity derived by the deviation quantity deriving unit.Type: GrantFiled: June 29, 2018Date of Patent: October 18, 2022Assignee: ADVICS CO., LTD.Inventors: Tatsuya Hiromura, Yukio Mori, Masayuki Asano

Publication number: 20220178708Abstract: A control device of a vehicle controls an actuator of the vehicle to cause the vehicle to travel based on a follow-up route. The control device includes a width information obtaining unit that obtains a road width in which the vehicle can pass on a road on which the vehicle travels. The control device includes a locus follow-up control unit that creates a follow-up route based on the obtained road width. The locus follow-up control unit derives a control amount for causing the vehicle to travel along the follow-up route.Type: ApplicationFiled: April 7, 2020Publication date: June 9, 2022Applicant: ADVICS CO., LTD.Inventors: Tatsuya HIROMURA, Yosuke OMORI

Patent number: 11220248Abstract: A control device including a valve-opening control unit that reduces the current value below the holding current value and increases the opening degree of the differential pressure adjustment valve when an increase in a manipulated variable of a braking operation member has been detected while holding control is being performed; and a valve-closing control unit that, when a decrease in the manipulated variable of the braking operation member has been detected while the opening degree of the differential pressure adjustment valve has been increased by the valve-opening control unit, performs a pushing process of increasing the current value above the holding current value and closing the differential pressure adjustment valve, and a holding process of setting the current value to the holding current value after the pushing process has ended.Type: GrantFiled: May 23, 2018Date of Patent: January 11, 2022Assignee: ADVICS CO., LTD.Inventors: Tatsuya Hiromura, Yukio Mori

Patent number: 11198441Abstract: This vehicle control device is provided with: a determination unit for determining whether proscribed conditions are satisfied, including the inability to determine that a longitudinal acceleration target value is fluctuating and the ability to determine that the longitudinal acceleration of a vehicle is fluctuating; and a cooperative control unit which, on the condition that it has been determined that the prescribed conditions are satisfied, performs a braking/driving cooperative process to hold a torque output from one of a driving torque generation device and a braking torque generation device at a value which is larger than the torque at the point in time at which the prescribed conditions were met, and adjusts the torque output from the other device through feedback control using the longitudinal acceleration target value and the longitudinal acceleration of the vehicle.Type: GrantFiled: February 23, 2018Date of Patent: December 14, 2021Assignee: ADVICS CO., LTD.Inventors: Masayuki Asano, Yukio Mori, Tatsuya Hiromura
