Abstract
A force sense imparting type input apparatus includes an operation portion, an actuator for imparting a force sense to the operation portion, a position sensor for detecting an operating direction and an operating quantity of the operation portion, a temperature sensor for detecting a temperature of the actuator, and a controller for acquiring a position signal and a temperature signal and outputting driving signal of the actuator. A correction control portion provided to the controller determines a calorific value of the actuator from the temperature signal, then a correction value of driving power supplied to the actuator from the calorific value so calculated, adds a correction value of driving power of the actuator at the time of a normal operation and decides driving power of the actuator at the time of over-heat.
