Publication number: 20130191002Abstract: A drive assist system includes: an acceleration change pattern setting portion that sets an acceleration change pattern of a vehicle that is a pattern of change in acceleration of the vehicle that occurs while the vehicle travels on a road; and a drive plan generating portion that generates a drive plan for the vehicle based on the acceleration change pattern set by the acceleration change pattern setting portion. The drive assist system generates a drive plan satisfying three conditions, namely, a kinetic model of the vehicle, a passing point of each corner, and an acceleration change pattern, using a solution to two-point boundary-value problems.Type: ApplicationFiled: October 12, 2011Publication date: July 25, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuki Minase, Koji Nakai

Publication number: 20130018562Abstract: A problem is to provide a vehicle control device, which performs travel control prepared for an unforeseen event by setting a tire friction circle to be small on a site on a road on which it is highly possible that the unforeseen event is found with delay due to a curve and poor visibility. An ECU sets a target speed with a predetermined allowance for a limit speed which is an upper limit speed of the vehicle, at a point at which a risk cannot be expected easily on a path along which the vehicle travels and generates a planned speed pattern which is a speed pattern of the path, based on the limit speed and the target speed.Type: ApplicationFiled: March 29, 2010Publication date: January 17, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koji Nakai, Takashi Suzuki

Publication number: 20110264327Abstract: A vehicle control device capable of improving the reliability related to vehicle control is provided. The vehicle control device which controls a vehicle along the target trajectory includes a target trajectory setting section which sets the target trajectory of the vehicle. A clothoid section setting section sets a clothoid section with a fixed curvature change rate of the target trajectory. An elapsed time calculating section calculates the time elapsed after the vehicle enters the clothoid section. A vehicle control operation section calculates a tire angle command value, which is used for steering control of the vehicle, on the basis of the target trajectory set by the target trajectory setting section, which performs vehicle control in the clothoid section on the basis of the time elapsed calculated by the elapsed time calculating section, and the time elapsed calculated by the elapsed time calculating section.Type: ApplicationFiled: January 18, 2010Publication date: October 27, 2011Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Koji Nakai
