Patent number: 8918247Abstract: A vehicle is provided with an air conditioning device that heats a passenger compartment, using cooling water passing through an internal combustion engine as a heat source, and a seat heater, which heats a seat in the passenger compartment by using an electric power from a battery as a heat source. An electronic control device performs EV travel of the vehicle by driving a motor generator while setting the internal combustion engine to a stop state and restarts the internal combustion engine when a cooling water temperature becomes equal to or less than a predetermined temperature during the EV travel. When a heating request is output to make the air conditioning device heat the passenger compartment during vehicle travel, the electronic control device reduces the heating degree of the air conditioning device and increases the heating degree by the seat heater during EV travel in comparison with non-EV travel.Type: GrantFiled: March 1, 2010Date of Patent: December 23, 2014Assignee: Toyota Jidosha Kabushiki KaishaInventors: Miyuki Goto, Manabu Orihashi, Keiichi Uno

Patent number: 8475337Abstract: When there is an extremely low ambient temperature, an electronic control unit controls operation of a circulation path for coolant water in such a manner that, after starting of an engine, the coolant water is supplied from the engine first to a throttle valve and an EGR valve and then to an oil warmer for a transmission. This solves a failure problem in the throttle valve and the EGR valve caused by frost formation at an early stage. As a result, desired operating performance of the vehicle is quickly ensured and heat management in the vehicle is carried out in a desired manner when there is an extremely low ambient temperature.Type: GrantFiled: May 7, 2009Date of Patent: July 2, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Masahide Ishikawa, Kaname Uzuki, Atsushi Morita, Keiko Tanaka, Yuki Miyamoto, Satoru Shiga, Masaki Morita, Miyuki Matsuda, Manabu Orihashi, Yoshihiro Saeki, Keiichi Uno, Hiroki Nishimura, Takayuki Kumamoto
