Patent number: 11608017Abstract: A vehicle front body structure is provided for reliably transferring a collision load to a crash can and a front frame by preventing a bumper beam from buckling during a small overlap collision. Bending rigidity of the bumper beam in a vehicle width direction is such that 1) a bending moment generated on the bumper beam when a collision load in a direction toward a vehicle rear side is applied to an extending section, which extends outward in the vehicle width direction from a crash can fixed section, is the highest in a vehicle width direction inner end portion of the crash can fixed section on a side where the collision load is applied, and 2) the bending moment is continuously reduced as a distance from the vehicle width direction inner end portion in the vehicle width direction increases.Type: GrantFiled: June 23, 2021Date of Patent: March 21, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Takashi Narahara, Nobuyuki Shibutake, Yasushi Ishikawa, Yuichi Morita, Ken Fujimoto, Yusaku Yamaguchi

Patent number: 11591024Abstract: A side body structure of a vehicle can include: a hinge pillar; a front pillar that is coupled to an upper end portion of this hinge pillar via a bent section, extends upward to the rear, and is coupled to a front end portion of a roof side rail via a connected section; and an apron rein that extends forward from a position below the bent section in the hinge pillar, where the bent section can include an energy absorption section that is subjected to out-of-plane deformation in a longitudinal orthogonal direction of the front pillar and thereby can absorb collision energy when the collision energy, which can be directed rearward, is applied to the apron rein. The energy absorption section can be configured to include an outer bead section and an inner bead section respectively provided in an outer member and a lower inner member.Type: GrantFiled: July 16, 2021Date of Patent: February 28, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Yasushi Ishikawa, Yuichi Morita, Ken Fujimoto, Yusaku Yamaguchi, Matsubara Hiroshi, Miyoshi Katsuhisa, Yokogi Yuji

Patent number: 11591025Abstract: A front vehicle-body structure controls inward breakage of an apron reinforcement in the event of a small overlap collision, without increasing weight. Embodiments include a pair of right and left apron reinforcements extending in a vehicle front-rear direction; and a pair of right and left hinge pillars respectively connected to rear ends of the pair of apron reinforcements. A reinforcement outer member of the apron reinforcement includes a linear portion extending in the vehicle front-rear direction from a rear end of the apron reinforcement connected to the hinge pillar to an intermediate portion of the apron reinforcement. A horizontal bead, provided as a deformation facilitating portion to facilitate deformation toward an inside of a vehicle body, is disposed on an outer surface portion positioned on a vehicle-width-direction outer side of the linear portion, the horizontal bead having a reduced longitudinal rigidity toward a front side in the vehicle front-rear direction.Type: GrantFiled: July 19, 2021Date of Patent: February 28, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Yasushi Ishikawa, Yuichi Morita, Yusuke Desaki, Yusuke Matsumura, Ken Fujimoto, Yusaku Yamaguchi

Patent number: 11541941Abstract: A front vehicle-body structure is provided that is lightweight and reduces an impact load transmitted to lower limbs of an occupant. Embodiments include a transmission disposed in a vehicle front portion, a dash lower panel dividing an inside from an outside of a vehicle cabin in a vehicle rear of the transmission, and an organ type accelerator pedal disposed on a vehicle-width-direction inner side of the dash lower panel opposed to the transmission. The dash lower panel includes a panel rear portion in which the accelerator pedal is arranged, a panel front portion extending from the panel rear portion to a vehicle front upper side, and a fragile portion extending in a vehicle width direction along a boundary between the panel rear portion and the panel front portion, which is fragile compared to the panel rear portion and the panel front portion.Type: GrantFiled: March 19, 2021Date of Patent: January 3, 2023Assignee: MAZDA MOTOR CORPORATIONInventors: Yuki Nagashima, Masaru Chikita, Yasushi Ishikawa, Ken Fujimoto

Patent number: 11441670Abstract: Because an EOP starts operating from when a decrease in discharge flow rate of an MOP is predicted or detected, a PL actual pressure that should be obtained with a PL command pressure set to a value for a required transmission torque is more easily maintained even when the discharge flow rate of the MOP becomes insufficient. After a lapse of a predetermined period of time from the start of operation of the EOP, the PL command pressure is temporarily set to a value higher than the value for the required transmission torque, and a regulator valve is controlled to operate to close a drain port. Therefore, the operation of the EOP in a high PL actual pressure is reduced, and a delay in response of a pressure regulating operation of the regulator valve in the process of reduction of the discharge flow rate of the MOP is reduced.Type: GrantFiled: September 28, 2020Date of Patent: September 13, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kota Fujii, Yuki Makino, Toshiaki Tamachi, Koji Hayashi, Tooru Matsubara, Ken Fujimoto, Masato Nakano
