Publication number: 20240126280Abstract: An automatic driving system includes a control device that controls automatic driving of a vehicle, and a storage device that contains external environment information indicating an external environment of the vehicle. A driving transition zone is a zone in which a driver of the vehicle takes over at least a part of driving of the vehicle, from the control device. A termination target velocity is a target velocity of the vehicle at an end point of the driving transition zone. The control device variably sets the termination target velocity, depending on the external environment at the end point or the external environment surrounding the end point. Then, the control device controls the velocity of the vehicle in the driving transition zone, such that the velocity of the vehicle at the end point is the termination target velocity.Type: ApplicationFiled: December 26, 2023Publication date: April 18, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takaaki TANAKA, Kenichiro AOKI, Masayuki KATOH

Patent number: 10000237Abstract: In a driving support device for a vehicle including a collision avoidance support system and a lane travel support system, a steering control amount is set while maintaining an appropriate relationship between both of the systems. This is by setting a lower upper limit value for the steering torque command during collision avoidance as compared to lane travel support. However, a gradient (i.e., rate of change) of the collision avoidance is set to be greater than a gradient of the lane travel support. As a result, the driving support device balances collision avoidance and lane travel support to have quick response during collision avoidance, and maintaining the ability to adapt to wide changes in road condition during lane travel support.Type: GrantFiled: October 5, 2016Date of Patent: June 19, 2018Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Masayuki Katoh
