摘要： PROBLEM TO BE SOLVED: To solve the problem that in a conventional lane change support device, white lane information is used only for calculating the relative information between its own vehicle and a peripheral vehicle, and whether or not the lane change support of its own vehicle is allowed is not determined from road information, so that the lane change to a restricted adjacent lane is supported, and acceleration control is performed on a road with a large curvature which may become dangerous when the vehicle speed is increased.
SOLUTION: A lane change support device is provided with: a first control mode for permitting a function for supporting lane change; a second control mode for prohibiting the function for supporting lane change; a road information acquisition part for acquiring road information when its own vehicle is traveling; a relative information acquisition part for acquiring the relative information between its own vehicle and the peripheral vehicle; a selection part for selecting a control mode based on the road information acquired by the road acquisition part; and a control part for controlling its own vehicle based on the relative information acquired by the relative information acquisition part and the control mode selected by the selection part.

摘要： PROBLEM TO BE SOLVED: To solve a problem that a throttle valve is susceptible to hunting to degrade controllability, caused by increase in calculation amount to increase the time from detection of opening to driving of a motor through calculation of a control, when a motor-driven throttle valve performs feedback opening control by using an opening sensor attached to a rotational shaft of the throttle valve.
SOLUTION: If error of outputs of the opening sensors of the throttle valve and an accelerator pedal is large, the outputs are used after the error is corrected. The calculation result is reflected in the driving of the motor, and then abnormality diagnosis of the opening sensors is performed. If an abnormality is determined, application of current to the motor is shut off or suppressed within a predetermined value. Therefore, the time from the detection of the opening to the driving of the motor is shortened by the calculation time of the diagnosis.

摘要： PROBLEM TO BE SOLVED: To raise the temperature of tor-con oil to a prescribed temperature utilizing heat of exhaust gas or engine oil of an automobile, in a device formed in such a constitution that the tor-con oil is used in a power transmission medium for engaging/releasing operation of a clutch. SOLUTION: In a device formed in such a constitution that power generated by an engine 101 is transmitted to an automatic transmission 103 through a transmission input axis 202, heat generated in the engine 101 side, for example, high temperature heat held by exhaust gas is moved to the automatic transmission 103 side, and the temperature of tor-con oil 203 is raised rapidly. Namely, a heat exchanger 206 for an exhaust gas is arranged between an exhaust pipe 205 and an oil pan 204 in order to utilize heat of exhaust gas 207 for raising a temperature of the tor-con oil 203, in the case where exhaust gas 207 whose temperature is raised just after the engine 101 is started is delivered through the exhaust pipe 205. It is thus possible to raise the temperature of the tor-con oil 203 in the automatic transmission 103 at the time of cooling just after start.

摘要： PURPOSE: To prevent a position-determining accuracy from being deteriorated by influences of errors included in a GPS signal without using a distance sensor or a vehicle velocity sensor, by selectively using data with reduced influences of errors among position or velocity data obtained from the GPS signal. CONSTITUTION: A present position is automatically set with the use of a position obtained by a mobile position estimation part 18 or data from a GPS measuring part 7. A display-processing part 22 reads map data from a map memory 306 and sends image data to a display device 308. Then, an estimation/interruption process for estimating a mobile bearing is started. A mobile bearing is estimated by a bearing estimation part 146 from data of a gyro sensor 310 and a GPS receiver 304 and road link data from the memory 306. Further, in an estimation/ interruption process for estimating a mobile position mobile, a present position is estimated by the mobile position estimation part 18 from the calculated result at the bearing estimation/interruption process, positional data from a mobile position calculation part 12, velocity data from a velocity calculation part 142 and road data from the memory 306.
