Abstract
A heads up display arrangement for a motor vehicle includes a rotatable mirror positioned to reflect a light field produced by a picture generation unit such that the light field is again reflected by a windshield of the motor vehicle and is then visible to a human driver of the motor vehicle as a virtual image. A stepper motor is coupled to the rotatable mirror and rotates the mirror. A stepper motor driver is coupled to the stepper motor and sets a torque of the stepper motor. A temperature sensor detects a temperature associated with the stepper motor. An electronic processor is communicatively coupled to the temperature sensor and to the stepper motor driver. The electronic processor transmits a signal to the stepper motor driver to set a target torque for the stepper motor. The target torque is dependent upon the detected temperature.
