摘要:
A vehicle controlling device has a frictional engagement element provided between a drive motor and a driving wheel ; a shifting unit capable of selecting a travel range or a non-travel range; first obtaining unit configured to, during selection of the travel range, obtain a first parameter including at least a first motor torque value that is a torque value of the drive motor; second obtaining unit configured to, during selection of the non-travel range, obtain a second parameter including at least a second motor torque value that is a torque value of the drive motor; and operating unit configured to, on the basis of the first and second parameters, calculate a zero point hydraulic pressure command value at which the frictional engagement element starts to generate a torque capacity. It is therefore possible to detect a zero point of a clutch between the drive motor and the driving wheel.
