Patent number: 11967294Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.Type: GrantFiled: May 1, 2023Date of Patent: April 23, 2024Assignee: Sharp Display Technology CorporationInventors: Masaki Uehata, Yasuki Mori, Kohji Saitoh, Takayuki Mizunaga, Kazuya Kondoh, Takashi Nojima, Kazuhisa Yoshimoto, Kosuke Kawamoto, Hiroyuki Kito, Kazuki Nakamichi

Publication number: 20240109598Abstract: A vehicle body structure includes a dashboard extending in a vehicle width direction and defining a cabin and a power compartment in front of the cabin; a power unit arranged in the power compartment; a floor panel extending rearward in the cabin from the dashboard; and a dash crossmember projected forward from the dashboard and extending in the vehicle width direction. The dash crossmember has a first portion at least partially overlapping the power unit in a front view; and a second portion extending outward in the vehicle width direction from the first portion. A compressive strength of the first portion is lower than a compressive strength of the second portion.Type: ApplicationFiled: October 9, 2020Publication date: April 4, 2024Applicant: MAZDA MOTOR CORPORATIONInventors: Kazuki YAMAUCHI, Ippei KURODA, Akiko KAWAMOTO

Patent number: 11679772Abstract: A drive control system is provided, which is mounted on a vehicle configured to travel by operation of a driver. The drive control system includes an actuator configured to output a driving force for the vehicle to travel, an output sensor configured to detect a driving force requested by the operation of the driver, and a control device configured to control operation of the actuator based on the requested driving force detected by the output sensor. The control device sets a target output value by adding a given delay time to a requested output value set corresponding to the requested driving force, and controls the actuator so as to output the target output value based on a response characteristic of the actuator.Type: GrantFiled: July 22, 2020Date of Patent: June 20, 2023Assignee: Mazda Motor CorporationInventors: Kazuo Sasaki, Kazuki Kawamoto

Patent number: 11143118Abstract: To provide a control device for a vehicle capable of controlling the torque of a drive source so as to appropriately balance the suppression of body vibrations and the securing of a transient response during acceleration or deceleration. This control device for a vehicle includes an accelerator position sensor that detects the accelerator opening, a torque adjustment mechanism such as a throttle valve that adjusts the torque of an engine as the drive source of the vehicle, and a powertrain control module (PCM) that controls the torque adjustment mechanism based on the accelerator opening. The PCM sets the target acceleration of the vehicle based on the accelerator opening, sets the target torsion angle of the drive shaft based on the target acceleration, sets the target torque of the engine based on the target torsion, and controls the torque adjustment mechanism based on the target torque.Type: GrantFiled: May 20, 2019Date of Patent: October 12, 2021Assignee: Mazda Motor CorporationInventors: Yuichiro Yamane, Akira Tsuda, Yuki Ishiyama, Takefumi Takada, Yuto Sakasegawa, Kazuki Kawamoto, Jumpei Takeda, Hiroyuki Morioka, Shin Kato, Masahiro Nagoshi, Atsushi Yamasaki
