Patent number: 9694821Abstract: An upper limit value of an upward gradient of a road surface for starting neutral coasting is set to be larger than an upper limit of the upward gradient of the road surface for starting free-run coasting, so, when the upward gradient is relatively large and a coasting distance is short, the vehicle is caused to travel in the neutral coasting, and stop and restart of the engine are not carried out. Therefore, a decrease in drivability of the vehicle is suppressed. When the upward gradient is relatively small and the coasting distance is long, the vehicle is caused to travel in the free-run coasting, and supply of fuel to the engine is stopped, so fuel economy of the vehicle is obtained. Thus, it is possible to achieve both fuel economy and drivability of the vehicle during coasting on an upward gradient.Type: GrantFiled: October 15, 2013Date of Patent: July 4, 2017Assignee: Toyota Jidosha Kabushiki KaishaInventors: Takeaki Suzuki, Masaki Matsunaga, Yasunari Kido, Takayuki Kogure, Yukari Okamura, Rentaro Kuroki, Takuya Hirai, Masaki Mitsuyasu, Jonggap Kim, Akihiro Sato, Yusuke Kinoshita
