Vehicle control device and vehicle control method

A vehicle control method for controlling a vehicle including a transmission to which a torque is transmitted from a drive source, comprising:

• outputting a command for automatically stopping the drive source when a first predetermined condition is satisfied and outputting a command for restarting the drive source when a second predetermined condition is not satisfied after the command for automatically stopping the drive source is output;
• determining that the drive source has restarted when a third predetermined condition is satisfied after the command for restarting the drive source is output;
• and
• prohibiting the determination at least until the third predetermined condition is no longer satisfied while the third predetermined condition is satisfied and the command for restarting the drive source is output, and
• detecting a hydraulic pressure supplied by a hydraulic pressure supply unit adapted to be driven by the drive source and to supply the hydraulic pressure to the transmission,
• wherein the drive source is determined to have been restarted, assuming that the third predetermined condition has been satisfied, when the detected hydraulic pressure becomes equal to or higher than a predetermined hydraulic pressure;
• and
• wherein the restart determination is prohibited at least until the hydraulic pressure becomes less than the predetermined hydraulic pressure after the command for automatically stopping the drive source is output.

• drive source control means for outputting a command for automatically stopping the drive source when a first predetermined condition is satisfied and outputting a command for restarting the drive source when a second predetermined condition is not satisfied after the command for automatically stopping the drive source is output;
• drive source restart determination means for determining that the drive source has restarted when a third predetermined condition is satisfied after the command for restarting the drive source is output;
• restart determination prohibition means for prohibiting a restart determination by the drive source restart determination means at least until the third predetermined condition is no longer satisfied when the third predetermined condition is satisfied and the command for restarting the drive source is output,
• hydraulic pressure supply means for being driven by the drive source and for supplying a hydraulic pressure to the transmission;
• and
• hydraulic pressure detection means for detecting the hydraulic pressure supplied by the hydraulic pressure supply means,
• wherein the drive source restart determination means is adapted to determine that the drive source has restarted, assuming that the third predetermined condition has been satisfied, when the hydraulic pressure detected by the hydraulic pressure detection means becomes equal to or higher than a predetermined hydraulic pressure;
• and
• wherein the restart determination prohibition means is adapted to prohibit the restart determination at least until the hydraulic pressure becomes less than the predetermined hydraulic pressure after the command for automatically stopping the drive source is output.
