Abstract
A method for powerhop identification and mitigation includes receiving sensor data of a vehicle, such as wheel speed; determining a wheel jerk characteristics of the vehicle based on the wheel speed; determining a ride height of the vehicle; determining whether the vehicle is experiencing powerhop based on the wheel jerk characteristics and the ride height of the vehicle; and in response to determining that the vehicle is experiencing powerhop, adjusting a torque of the vehicle to mitigate the powerhop.
Claims18
A method for powerhop identification and mitigation, comprising:
- receiving sensor data of a vehicle, where the sensor data includes wheel speed;
- determining a wheel jerk characteristics of the vehicle based on the wheel speed;
- determining a ride height of the vehicle;
- determining whether the vehicle is experiencing powerhop based on the wheel jerk characteristics and the ride height of the vehicle;
- and
- in response to determining that the vehicle is experiencing powerhop, adjusting a torque of the vehicle to mitigate the powerhop,
- wherein the wheel jerk characteristics include a wheel jerk amplitude and a wheel jerk duration, wherein the wheel jerk amplitude is a second derivate of the wheel speed with respect to time.
A vehicle, comprising:
- a plurality of sensors each configured to generate sensor data, wherein the plurality of sensors includes at least one wheel speed sensor and at least one ride height sensor;
- a controller in communication with the plurality of sensors, wherein the controller is programmed to:
- receive sensor data from the plurality of sensors, where the sensor data includes wheel speed;
- determine a wheel jerk characteristics of the vehicle based on the wheel speed;
- determine the ride height of the vehicle using the sensor data;
- determine whether the vehicle is experiencing powerhop based on the wheel jerk characteristics and the ride height of the vehicle;
- and
- in response to determining that the vehicle is experiencing powerhop, adjust a torque of the vehicle to mitigate the powerhop,
- wherein the wheel jerk characteristics include a wheel jerk amplitude and a wheel jerk duration, wherein the wheel jerk amplitude is a second derivate of the wheel speed with respect to time.
