A driving assistance apparatus makes a drive force of a vehicle equal to an erroneous operation coping drive force which is smaller than an ordinary drive force in a period from a satisfaction of an erroneous operation start condition which is satisfied when an accelerator pedal is operated erroneously to a satisfaction of an erroneous operation end condition which is satisfied when the erroneous operation has ended. The erroneous operation coping drive force is set to a first drive force if the erroneous operation start condition becomes satisfied after a reoperation determination time point at which a time threshold elapses from when the erroneous operation end condition became last satisfied. Meanwhile, the erroneous operation coping drive force is set to a second drive force which is greater than the first drive force if the erroneous operation start condition becomes satisfied before the reoperation determination time point.

Driving assistance apparatus for erroneous accelerator pedal operation

Provided is a control apparatus for a vehicle configured to execute driving force suppression control when a predetermined erroneous operation condition is satisfied, the erroneous operation condition being satisfied when a first condition including at least an operation velocity condition is satisfied and a second condition is satisfied, the operation velocity condition being satisfied when an operation velocity which is an amount of change in an operation amount of an accelerator operation element per unit time is equal to or higher than an operation velocity threshold, and the second condition being satisfied when the operation amount becomes equal to or larger than a first operation amount threshold within a first time threshold from a time point at which the first condition is satisfied.

Vehicle control apparatus and method

When an electronic mail is transmitted, a computer outputs to a display device a transmission confirmation screen on which a destination or an attached file name is displayed, the destination or the attached file name being different from a destination or an attached file name that has been set by a user in the electronic mail, and on which whether transmission of the electronic mail will be performed is selectable. Upon receipt of selection of whether the transmission will be performed, the computer outputs to the display device message information that varies according to a result of the selection of whether the transmission will be performed on the transmission confirmation screen.

A device is provided for detecting a malfunction of an air fuel ratio sensor disposed downstream of a catalytic converter in an exhaust passage of an engine. The device calculates a differential value of a sensor output with respect to time. Then the device compare the differential value of said sensor output with a predetermined value and calculate a frequency of the differential value of the sensor output which exceeds the predetermined value. Then the device compares the frequency with a predetermined value and determine that the sensor is malfunctioning if the frequency does not exceed the predetermined value.

A device for determining the degree of deterioration of catalyst of a catalytic converter arranged in an internal combustion engine exhaust system is disclosed. The device comprises an O.sub.2 sensor which is arranged in the internal combustion engine exhaust system downstream of the catalytic converter. The O.sub.2 sensor has the low oxidization and deoxidization ability on the detection surface thereof. The device determines the degree of deterioration of the catalyst by comparing a value in connection with an extra O.sub.2 concentration on the basis of a current output of the O.sub.2 sensor in the exhaust gas at a predetermined air-fuel ratio with a basic value.
