Patent number: 8958970Abstract: A vehicle control system and a vehicle control device can switch control of a supporting device for support a drive of a vehicle between an ordinary travel in which the vehicle travels in a state that a power source for causing the vehicle to travel is operated and an inertia travel in which the vehicle travels in a state that an operation of the power source is stopped. Accordingly, since the vehicle control system and the vehicle control device switch the control of the supporting device between the ordinary travel and the inertia travel, the vehicle control system and the vehicle control device achieve an effect that the vehicle can be caused to appropriately travel by inertia.Type: GrantFiled: May 13, 2010Date of Patent: February 17, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masaki Matsunaga, Nobukazu Ueki, Hiroshi Tsujii, Koji Ito

Patent number: 8831830Abstract: A vehicle controlling system starts an engine by a starting device based on a vehicle speed, and changes a predetermined vehicle speed, which is a vehicle speed when the engine is started, in response to a state of an electric storage device, when an execution of inertial running in which the engine is stopped to allow the vehicle to run with inertia. Power consumed by a power steering device is changed in response to a vehicle speed. The predetermined vehicle speed is a lower limit vehicle speed in a vehicle speed range in which the electric storage device can output power consumed by the starting device when the engine is started and power consumed by the power steering device at the same time, or a vehicle speed close to the lower limit vehicle speed in the vehicle speed range.Type: GrantFiled: May 19, 2010Date of Patent: September 9, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Koji Ito, Hiroshi Tsujii, Masaki Matsunaga, Nobukazu Ueki
