PURPOSEFUL BRAKE-INDUCED WHEEL LOCKUP FOR VEHICLE STABILITY CONTROL IN AUTONOMOUS VEHICLES
Systems and Methods for controlling an autonomous vehicle, may include: receiving sensor data, the sensor data comprising vehicle parameter information for the autonomous vehicle; using the sensor data to determine a vehicle state for the autonomous vehicle, wherein the vehicle state comprises information regarding a magnitude of an actual or predicted effective understeer gradient for the vehicle; computing a yaw moment required to correct the effective understeer gradient based on the magnitude of the effective understeer gradient; and determining a combination of one or more vehicle control inputs, including applying a brake torque, to correct the effective understeer gradient; applying the brake torque to a single wheel of the vehicle, wherein an amount of brake torque applied is sufficient to lock up the single wheel to create a yaw moment on the vehicle to achieve the computed yaw moment required to correct the effective understeer gradient.

Method of determining the yaw rate of a target vehicle
This disclosure describes a radar system configured to estimate a yaw-rate and an over-the-ground (OTG) velocity of extended targets in real-time based on raw radar detections. This disclosure further describes techniques for determining instantaneous values of lateral velocity, longitudinal velocity, and yaw rate of points of a rigid body in a radar field-of-view (FOV) of the radar system.

Control apparatus for vehicle and control method for vehicle
A control apparatus for a vehicle includes: a target yaw rate calculator; a primary limit yaw rate calculator; a yaw rate comparator; a secondary limit yaw rate calculator; and a vertical load controller. The target yaw rate calculator calculates a target yaw rate of the vehicle. The primary limit yaw rate calculator calculates a primary limit yaw rate on a basis of a vertical load on a wheel. The yaw rate comparator compares the target yaw rate with the primary limit yaw rate. The secondary limit yaw rate calculator calculates a secondary limit yaw rate in a case where a distribution of the vertical load on the wheel is changed in a case where the target yaw rate exceeds the primary limit yaw rate. The vertical load controller changes the vertical load on a basis of the secondary limit yaw rate.
