1. An apparatus for controlling a vehicle, comprising:
- an acceleration sensor that detects an acceleration of the vehicle; and
an electronic control unit that is programmed to execute an output reduction process of reducing an output from a power source of the vehicle with use of a value detected by the acceleration sensor, such that the acceleration does not exceed a predetermined threshold value,wherein, when there is an abnormality in the acceleration sensor, the electronic control unit is programmed to set the predetermined threshold value to be greater than that in a case in which there is no abnormality in the acceleration sensor, and limit a vehicle speed to a predetermined speed value or lower.

Abstract
An electronic control unit reduces output of an engine using a detection value of an acceleration sensor such that acceleration of a vehicle does not exceed a predetermined threshold value. In a case where there is an abnormality in the acceleration sensor, the electronic control unit sets the acceleration threshold value to be greater than that in a case where there is no abnormality, and the electronic control unit limits the vehicle speed to a predetermined value or slower.

3. An apparatus for controlling a vehicle, comprising:
-
a sensor that detects a parameter that indicates a traveling state of the vehicle that varies according to an amount of accelerator operation; and an electronic control unit that is programmed to execute an output reduction process of reducing an output from a power source of the vehicle with use of the parameter during operation of the power source, wherein, when there is an abnormality in the sensor, the electronic control unit is programmed to set a degree of reduction in output by the output reduction process to be smaller than that in a case in which there is no abnormality in the sensor. - View Dependent Claims (4, 5)
