Abstract
A controlling device includes a range switch mechanism, range switch operating means, operation frequency monitoring means, and heat generation limit controlling means. The range switch mechanism is adapted to change a shift range using a motor. Through the range switch operating means, an occupant inputs a required shift range. The motor is controlled in accordance with the required shift range such that the shift range is changed into the required shift range. The operation frequency monitoring means monitors an operation frequency of the range switch operating means. The heat generation limit controlling means switches a control of the motor to a heat generation limit control when the operation frequency of the range switch operating means exceeds a predetermined frequency.
