Methods and vehicles are provided for providing haptic feedback to a vehicle occupant. In one embodiment, the method includes evaluating conditions related to a vehicle, selecting a type of haptic alert based on the evaluated conditions, selecting a pattern of haptic actuators to command based on the type of haptic alert and a location of the haptic actuators in a seat of the vehicle, selecting a number of active haptic periods to command based on the type of haptic alert, selecting a duration of the active haptic periods and a duration of inactive haptic periods based on the type of haptic alert, and generating a signal indicating the active haptic periods based on the selected pattern of haptic actuators, the selected number of active haptic periods, and the selected duration of the active and inactive haptic periods.

1. A method executed by a controller, the method comprising: evaluating conditions related to a vehicle;selecting a type of haptic alert based on the evaluated conditions;selecting a pattern of haptic actuators to command based on the type of haptic alert and a location of the haptic actuators in a seat of the vehicle;selecting a number of active haptic periods to command based on the type of haptic alert;selecting a duration of the active haptic periods and a duration of inactive haptic periods based on the type of haptic alert; andgenerating a signal indicating the active haptic periods based on the selected pattern of haptic actuators, the selected number of active haptic periods, and the selected duration of the active and inactive haptic periods. 2. The method of claim 1 wherein selecting a pattern of haptic actuators to command includes at least one of selecting a haptic actuator adjacent to a driver's right leg and selecting a haptic actuator adjacent to a driver's left leg based on the type of haptic alert and the location of the evaluated conditions. 3. The method of claim 1 wherein selecting a pattern of haptic actuators to command includes selecting at least one of a zigzag pattern and a circular pattern. 4. The method of claim 1 wherein selecting the number of active haptic periods includes increasing the number of active haptic periods with increasing severity of the alert and includes decreasing the number of active haptic periods with decreasing severity of the alert. 5. The method of claim 1 wherein selecting the duration of the inactive haptic periods includes decreasing a duration of inactive haptic periods between active haptic periods as the vehicle approaches an object during a park assist application. 6. The method of claim 1 wherein selecting the duration of active and inactive haptic periods includes adjusting alert cadence to indicate a multiple scenario event. 7. The method of claim 1 further including combining active haptic periods of multiple haptic alert types to indicate multiple events. 8. The method of claim 1 wherein evaluating conditions includes evaluating data from sensors associated with the vehicle. 9. The method of claim 1 wherein selecting a type of haptic alert includes selecting at least one of a Lane Departure Warning, a Lanekeeping Assist, a Rear Cross Traffic Alert, a Forward Collision Alert, a Collision Imminent Braking, an Adaptive Cruise Control, a Backup Warning, a Front Park Assist, and a Rear Park Assist event. 10. A method executed by a controller, the method comprising: evaluating conditions related to a vehicle based on data from sensors associated with the vehicle;selecting a type of haptic alert based on the evaluated conditions;selecting at least one of a haptic actuator adjacent to a driver's right leg and a haptic actuator adjacent to a driver's left leg based on the type of haptic alert and the location of the evaluated conditions;selecting a number of active haptic periods to command based on the type of haptic alert;selecting a duration of the active haptic periods and a duration of inactive haptic periods based on the type of haptic alert; andgenerating a signal indicating the active haptic periods based on the selected pattern of haptic actuators, the selected number of active haptic periods, and the selected duration of the active and inactive haptic periods. 11. The method of claim 10 wherein selecting the number of active haptic periods includes increasing the number of active haptic periods with increasing severity of the alert and includes decreasing the number of active haptic periods with decreasing severity of the alert. 12. The method of claim 10 further including combining active periods of multiple haptic alert types to indicate multiple events. 13. A vehicle comprising: a seat having a first bolster for supporting a right leg of a driver and a second bolster for supporting a left leg of the driver;a first haptic actuator disposed in the first bolster;a second haptic actuator disposed in the second bolster;a controller in communication with the first and second haptic actuator and that: evaluates conditions related to the vehicle;selects a type of haptic alert based on the evaluated conditions;selects a pattern of the first and second haptic actuators to command based on the type of haptic alert and the location of the evaluated conditions;selects a number of active haptic periods to command to the first and second haptic actuators based on the type of haptic alert;selects a duration of the active haptic periods and a duration of inactive haptic periods based on the type of haptic alert; andgenerates a signal indicating the active haptic periods based on the selected pattern of haptic actuators, the selected number of active haptic periods, and the selected duration of the active and inactive haptic periods. 14. The vehicle of claim 13 wherein the controller selects at least one of a zigzag pattern and a circular pattern to select a pattern of the first and second haptic actuators. 15. The vehicle of claim 13 wherein the controller increases the selected number of active haptic periods with increasing severity of the alert and decreases the number of active haptic periods with decreasing severity of the alert. 16. The vehicle of claim 13 wherein the controller decreases a duration of inactive haptic periods between active haptic periods as the vehicle approaches an object during a park assist application. 17. The vehicle of claim 13 wherein the controller adjusts an alert cadence to indicate a multiple scenario event. 18. The vehicle of claim 13 wherein the controller combines active periods of multiple haptic alert types to indicate multiple events. 19. The vehicle of claim 13 further including a plurality of sensors, and wherein the controller evaluates conditions based on data from sensors. 20. The vehicle of claim 13 wherein the controller selects a type of haptic alert that includes at least one of a Lane Departure Warning, a Lanekeeping Assist, a Rear Cross Traffic Alert, a Forward Collision Alert, Forward Collision Imminent Braking, and Adaptive Cruise Control event, Backup Warning, a Front Park Assist, and a Rear Park Assist event.
