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.
Claims5
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.
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 stop the output reduction process and limit a vehicle speed to a predetermined speed value or lower.
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.
