Abstract
A vehicle controller includes a plurality of driving power sources for transmitting torque to a wheel, and a starter for starting a first driving power source of the plurality of diving power sources. The first driving power source is stopped when a prescribed stopping condition is satisfied, and the stopped first driving power source is started by the starter when a prescribed restarting condition is satisfied. When the startability of the first driving power source has been degraded, stopping of the first driving power source is inhibited even when the prescribed stopping condition is satisfied.
Claims17
A vehicle controller for controlling a vehicle having a plurality of driving power sources for transmitting torque to a wheel, the plurality of driving power sources including at least first and second driving power sources;
- and a starter for starting the first driving power source;
- wherein the controller:
- stops the first driving power source when a prescribed stopping condition is satisfied, and starts the stopped first driving power source by the starter when a prescribed restarting condition is satisfied;
- and
- determines whether startability of the first driving power source by the starter has been degraded, and when the controller determines that the startability of the first driving power source has been degraded, the controller inhibits stopping of the first driving power source even when the prescribed stopping condition is satisfied.
A vehicle control method for controlling a vehicle having a plurality of driving power sources for transmitting torque to a wheel, and a starter for starting a first driving power source of the plurality of diving power sources are provided, the first driving power source is stopped when a prescribed stopping condition is satisfied, and the stopped first driving power source is started by the starter when a prescribed restarting condition is satisfied, comprising the steps of:
- determining whether startability of the first driving power source by the starter has been degraded;
- and
- inhibiting the stopping of the first driving power source, when the prescribed stopping condition is satisfied, when the startability of the first driving power source has been degraded.
