Publication number: 20230018675Abstract: The braking force control device detects an impossible state where one or some of the actuators are temporarily unable to generate a negative driving force, and a predictive state where one or some of the actuators are predicted to become unable to generate a negative driving force. Every time the coasting state occurs before establishment of the impossible state and after establishment of the predictive state, the braking force control device gradually increases the negative driving force generated by the corresponding one or ones of the actuators. Even when the coasting state occurs in the impossible state, the braking force control device does not cause the corresponding one or ones of the actuators to generate a driving force. Every time the coasting state occurs after the impossible state, the braking force control device gradually decreases the negative driving force generated by the corresponding one or ones of the actuators.Type: ApplicationFiled: September 23, 2022Publication date: January 19, 2023Applicant: OYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tsutomu KAWANISHI, Shun SATO, Masahiro NISHIU

Patent number: 9845615Abstract: A mounting structure of a decorative cap includes a door panel, a cylinder lock fixed to the door panel, and a decorative cap member. A protrusion portion of a cylinder lock protruding 5 from the door panel is covered with the decorative cap member. The decorative cap member includes a water guide channel guiding infiltrated water from a gap between a key insertion opening and a surface of the cylinder lock, to a water ejection opening which is opened on a peripheral wall. The key insertion opening 10 exposes a key insertion section of the cylinder lock.Type: GrantFiled: November 10, 2016Date of Patent: December 19, 2017Assignee: ALPHA CORPORATIONInventors: Shinji Ichikawa, Tsutomu Kawanishi

Patent number: 9683659Abstract: When an alternator load torque Talt is larger than a threshold ?, a lockup clutch is released. Thus, a deceleration G can be restrained from becoming too large due to the alternator load torque Talt. Besides, the threshold ? is changed in accordance with a speed ratio ? of a continuously variable transmission. Thus, the deceleration G can be favorably controlled within a predetermined range. For example, in a vehicle state where a deceleration is unlikely to be achieved due to the smallness of the speed ratio ?, the threshold ? is large. Therefore, the lockup clutch is unlikely to be released, and the deceleration G is likely to be secured.Type: GrantFiled: February 17, 2016Date of Patent: June 20, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Taichi Washio, Tsutomu Kawanishi
