Haptic feedback systems for vehicle acceleration pedals

A haptic feedback system for a vehicle acceleration pedal, the haptic feedback system comprising:

• an acceleration pedal configured to control acceleration of a motor of a vehicle;
• a vibration transducer mechanically connected with the acceleration pedal, the vibration transducer configured to vibrate the acceleration pedal according to a haptic feedback signal supplied to the vibration transducer;
• at least one vehicle sensor configured to sense one or more vehicle operation parameters;
• and
• a vehicle control module configured to:
• obtain the one or more vehicle operation parameters via the at least one vehicle sensor;
• selectively supply the haptic feedback signal to the vibration transducer according to the one or more vehicle operation parameters, to selectively vibrate the acceleration pedal;
• determine a transmission gear state of the vehicle;
• select a first waveform shape of the haptic feedback signal and supply the haptic feedback signal to the vibration transducer in response to a determination that the transmission gear state is a drive gear state;
• select a second waveform shape of the haptic feedback signal and supply the haptic feedback signal to the vibration transducer in response to a determination that the transmission gear state is a reverse gear state, wherein the second waveform shape is different than the first waveform shape, and each of the first waveform shape and the second waveform shape include at least one of a triangle wave signal, a square wave signal or a sine wave signal;
• and
• inhibit supplying the haptic feedback signal to the vibration transducer in response to a determination that the transmission gear state is a neutral state.
