A posture estimation method includes calculating a posture change amount of an object based on an output of an angular velocity sensor, predicting posture information of the object by using the posture change amount, limiting a bias error in a manner of limiting a bias error component of an angular velocity around a reference vector in error information, and correcting the predicted posture information of the object based on the error information, the reference vector, and an output of a reference observation sensor. A posture estimation device for performing the method includes a posture-change amount calculation unit, a posture information prediction unit, an error information update unit, a bias error limitation unit, and a posture information correction unit.

Methods and apparatus to compensate for body roll in vehicle weight calculations are disclosed. An example method includes receiving sensor data from sensors of a vehicle, determining a weight of the vehicle and determining a body roll of the vehicle. The example method further includes comparing the body roll to a threshold and, if the body roll satisfies the threshold, adjusting the determined weight of the vehicle based on the determined body roll and properties of a suspension system of the vehicle.

The disclosed technology is a vehicle object detection radar system incorporating an inertial measurement unit (IMU). The IMU may obtain input signals of, or relating to, for example, relative motion, acceleration, object detection angle, sway and vibration of the vehicle and/or any towed trailer, and process them for relay to the vehicle operator as operating information and possibly alarms. Also, the obtained IMU signals may be relayed directly to the vehicle's object detection radar systems and central control for automatic adjustment and control thereof.

A method for warning a driver of a motorcycle and a ride assistant controller for implementing or controlling such method are described. The method includes monitoring traffic situations based on signals from at least one sensor; upon detecting a critical traffic situation based on the signals from the at least one sensor, warning the driver by inducing an acceleration change onto the motorcycle; wherein a current lean angle of the motorcycle is monitored and a manner and/or degree of inducing the acceleration change onto the motorcycle is set taking into account the current lean angle of the motorcycle.
