Abstract:
1. A method, comprising: selecting, with a controller, a pattern of active haptic periods during which the controller will command a plurality of haptic actuators disposed in a seat of a vehicle to generate haptic pulses; determining, with the controller, a desired voltage of a signal supplied to the haptic actuators that indicates the active haptic periods to generate a desired intensity of haptic pulses; measuring, with the controller, an actual voltage supplied to the controller by an energy storage device of the vehicle; calculating, with the controller, a pulse width modulation (PWM) pattern that simulates the desired voltage using the actual voltage; and generating, with the controller, a signal that indicates the active haptic periods based on the PWM pattern to command the haptic actuators to generate the desired intensity of haptic pulses.
