Latest Patents

One of his latest patents is a vehicle stability control system and method. This invention discloses various methods for detecting or controlling vehicle stability. Certain embodiments provide a method for performing hill hold control for a vehicle, a method for detecting a vehicle sliding into loss of control, and a method for controlling a vehicle's sliding into loss of control. The methods for detecting sliding into loss of control may include comparing the vehicle's longitudinal velocity gradient with a reference speed computed from wheel speed sensor inputs and detecting both lateral and longitudinal velocities when sliding is detected. Control methods may involve calculating a vehicle pitch angle from various acceleration rates and calculating a sideslip angle.

Another aspect of his vehicle stability control system comprises a 5-sensor cluster and a stability controller. This controller communicates with the sensor cluster to receive signals corresponding to lateral acceleration, longitudinal acceleration, yaw rate, roll rate, and pitch rate. The stability controller determines the necessary braking or throttle amounts to maintain vehicle stability. The system is designed to respond to various scenarios detected by measured and calculated signals.
