Patent number: 12252038Abstract: An ECU of a vehicle executes a regeneration process to control an electric motor so as to generate regenerative torque during deceleration caused by an accelerator OFF. The ECU executes a torque gradual decrease process to decrease the regenerative torque in a wheel slip detection state more gradually at a time when a brake pedal is depressed after a start of the deceleration and ABS control is not activated than a time when the brake pedal is not depressed after the start of the deceleration. The ECU executes a hydraulic pressure increase process to increase the upstream hydraulic pressure such that, when the ABS control is activated while the brake pedal is depressed after the start of the deceleration, the upstream hydraulic pressure has a value necessary for generating a braking torque having a magnitude according to the regenerative torque generated at a start of the ABS control.Type: GrantFiled: October 17, 2022Date of Patent: March 18, 2025Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, SUBARU CORPORATIONInventors: Takami Iwamoto, Shun Nagai, Yuto Yokoyama, Junichi Katsumata, Shotaro Arai, Hiroki Maeda, Masahiro Hara, Daigo Tateishi

Publication number: 20240208472Abstract: A vehicle travel control device includes a plurality of wheel speed detection devices and a control unit. A plurality of wheel speed detection devices detects the wheel speed of each of the plurality of wheels. The control unit performs vehicle travel control (anti-skid control) based on the wheel speed detected by the wheel speed detection device.

Patent number: 11458940Abstract: A brake ECU sets target slippage degrees of three wheels other than the front outer wheel to the slippage degree of the front outer wheel and feedback-controls the braking forces of the three wheels such that the actual slippage degrees of the three wheels approach the target slippage degrees. The brake ECU computes a correction amount for the slip ratio deviation of the front inner wheel such that the slip ratio deviation becomes zero. The brake ECU multiplies the correction amount for the slip ratio deviation by a load ratio and uses the resultant value as a correction amount for the slip ratio deviation of the rear inner wheel. The brake ECU corrects the slip ratio deviation by using the computed correction amount.Type: GrantFiled: September 20, 2019Date of Patent: October 4, 2022Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, ADVICS CO., LTD.Inventors: Masahiro Hara, Hiroaki Nagase, Kei Amamoto
