Haptic feedback shift knob
Automotive vehicles having a manual shift transmission, with driver feedback to indicate when a shift change is recommended or to provide other event notifications.
1. A manual-transmission vehicle comprising:
a shift knob responsive to a driver for shifting a manual transmission;
a haptic feedback device incorporated in the shift knob; and
a controller determining a time for shifting the shift knob according to a powertrain optimization and activating the haptic feedback device at the determined time to provide a shift change notification to the driver as a tactile pulse.
2. The vehicle of claim 1 further comprising:
a sensor incorporated in the shift knob to detect the presence of a driver's hand on the shift knob; and
an auditory feedback device;
wherein the controller activates the auditory feedback device at the determined time if the sensor does not detect the presence of the driver's hand.
3. The vehicle of claim 2 wherein the controller activates the haptic feedback device only if the sensor detects the presence of the driver's hand.
4. The vehicle of claim 1 further comprising:
an auditory feedback device wherein the controller activates the auditory feedback device at the determined time together with the tactile pulse for the shift change notification.
5. The vehicle of claim 1 wherein the haptic feedback device is comprised of a motor and unbalanced mass configured to shake the shift knob when activated.
6. The vehicle of claim 1 further comprising a human machine interface responsive to the driver for configuring a strength of vibration for the tactile pulse.
7. The vehicle of claim 1 wherein the powertrain optimization is comprised of an optimization of fuel economy.
8. The vehicle of claim 1 further comprising a human machine interface responsive to the driver for configuring the powertrain optimization by selecting between a fuel economy optimization and a performance optimization.
9. A method for providing a shift change notification in a vehicle with a manual transmission, comprising the steps of:
gathering vehicle data including a vehicle speed and engine speed to determine a time for shifting the manual transmission according to a powertrain optimization; and
activating a haptic feedback device incorporated in a shift knob at the determined time to provide a shift change notification to a driver as a tactile pulse.
10. The method of claim 9 further comprising the step of activating an auditory feedback device at the determined time together with the tactile pulse for the shift change notification.
11. The method of claim 9 further comprising the step of configuring the powertrain optimization by selecting between a fuel economy optimization and a performance optimization.
12. A method for providing a shift change notification in a vehicle with a manual transmission, comprising the steps of:
gathering vehicle data including a vehicle speed and engine speed to determine a time for shifting the manual transmission according to a powertrain optimization;
checking for the presence of a driver's hand on a shift knob; and
activating a haptic feedback device incorporated in the shift knob if the driver's hand is on the shift knob at the determined time to provide a shift change notification to the driver as a tactile pulse.
13. The method of claim 12 further comprising the step of:
activating an auditory feedback device if the driver's hand is not on the shift knob at the determined time for the shift change notification.
14. The method of claim 12 further comprising the step of configuring the powertrain optimization by selecting between a fuel economy optimization and a performance optimization.
