Abstract
The present invention is applied to a control device for controlling a vehicle that travels using a driving force of an engine. The control device for the vehicle includes the vehicle speed detection unit that detects the vehicle speed, and the automatic engine stop unit that performs the automatic engine stop after a prescribed time elapses from when the vehicle speed detection unit detects that the vehicle is in the stopped state. When a failure of the vehicle speed detection unit is detected, the automatic engine stop by the automatic engine stop unit is prohibited.
Claims15
A vehicle control method for controlling a vehicle that travels using a driving force of an engine, the vehicle comprising a vehicle speed detection unit that comprises a wheel speed sensor that detects a rotation speed of a wheel and a gear rotation sensor that detects rotation of a gear in a transmission, the vehicle control method comprising:
- detecting a vehicle speed using the vehicle speed detection unit;
- performing automatic engine stop after a prescribed time elapses from when the vehicle is determined to be in a stopped state based on a detection result of the vehicle speed, and
- prohibiting the automatic engine stop when failures of both the wheel speed sensor and the gear rotation sensor are detected.
A vehicle control device for controlling a vehicle that travels using a driving force of an engine, the vehicle control device comprising:
- a vehicle speed detection unit comprising a wheel speed sensor that detects a rotation speed of a wheel and a gear rotation sensor that detects rotation of a gear in a transmission;
- and
- an automatic engine stop unit configured to perform automatic engine stop after a prescribed time elapses from when the vehicle is determined to be in a stopped state based on a detection result of the vehicle speed detection unit, wherein;
- the automatic engine stop unit prohibits the automatic engine stop when failures of both the wheel speed sensor and the gear rotation sensor are detected.
A vehicle control method for controlling a vehicle that travels using a driving force of an engine, the vehicle control method comprising:
- detecting a vehicle speed;
- performing automatic engine stop after a prescribed time elapses from when the vehicle is determined to be in a stopped state based on a detection result of the vehicle speed;
- prohibiting the automatic engine stop when a failure of a vehicle speed detection unit for detecting the vehicle speed is detected;
- detecting opening and closing of a driver-side door of the vehicle;
- and
- when the automatic engine stop is prohibited and the driver-side door is detected to be opened, providing a notification that the automatic engine stop will not be performed to a driver of the vehicle.
