Patent number: 8374747Abstract: A failure diagnostic apparatus determines the environment in which the condition of a vehicle is examined and selects an appropriate storage location for information regarding the condition of the vehicle. In particular, the failure diagnostic apparatus includes a vehicle-condition diagnostic portion, a plurality of failure-information storage portions, a diagnostic-environment determination portion, and a storage selection portion. When the vehicle-condition diagnostic portion determines that a failure has occurred, the diagnostic-environment determination portion determines the environment in which the condition of the vehicle is examined. Then, based on the diagnostic environment determined by the diagnostic-environment determination portion, the storage selection portion selects at least one storage portion of the plurality of failure-information storage portions to store information regarding the failure.Type: GrantFiled: June 23, 2010Date of Patent: February 12, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventor: Hiroki Morozumi

Patent number: 8069827Abstract: A drive component for driving an electric water pump for causing engine coolant to flow is mounted in an engine compartment. When the ignition is off and the temperature of a exhaust heat recovery device is above a temperature, an ECU estimates a peak temperature in the engine compartment after the stop of the engine. When the peak temperature is above a temperature, the ECU stops the engine and drives the electric water pump and an electric fan for cooling the drive component for driving the electric water pump.Type: GrantFiled: September 25, 2008Date of Patent: December 6, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yoshitaka Watanabe, Koichi Mizutani, Naoki Toyofuku, Hiroki Morozumi

Patent number: 7869917Abstract: A vehicle control apparatus includes a first storage area in which malfunction record information that is information on the record of a malfunction in a vehicle, and identifying information used to identify a program are stored in a nonvolatile manner; and a second storage area in which the program is stored in a rewritable and nonvolatile manner. If the identifying information stored in the first storage area does not match the identifying information corresponding to the rewritten program stored in the second storage area when rewriting of the program stored in the second storage area is completed, the control portion erases the malfunction record information in the first storage area, and rewrites the identifying information stored in the first storage area to the identifying information corresponding to the rewritten program.Type: GrantFiled: February 8, 2008Date of Patent: January 11, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventor: Hiroki Morozumi
