A vehicle sideslip estimation system includes sensors mounted on a vehicle and a kinematic model receiving signals from the sensors to estimate a lateral velocity of the vehicle. A compensated acceleration calculator calculates a compensated lateral acceleration as a measure of conditions that result in a deviation of a measured lateral acceleration. A lateral acceleration calculator determines, based on the compensated lateral acceleration and the measured lateral acceleration, if a lateral acceleration error is larger than a predefined threshold. A filter corrects the estimated lateral velocity of the vehicle when the lateral acceleration error is larger than the predefined threshold. A velocity output register registers the estimated lateral velocity of the vehicle when the lateral acceleration error is smaller than the predefined threshold, and a sideslip calculator calculates a sideslip angle of the vehicle in real time from the registered lateral velocity of the vehicle and a vehicle longitudinal velocity.

Systems and methods are provided herein for operating a vehicle in a vehicle yaw mode. In response to initiating vehicle yaw mode, the system engages an open-loop mode, that provides open-loop forward torque to the outer wheels of the vehicle and open-loop backward torque to the inner wheels of the vehicle until a sufficient number of wheels are slipping. In response to determining that a sufficient number of wheels are slipping, engaging a closed-loop mode. While operating in the closed-loop mode, one or both of the wheel rotation and vehicle yaw rate are monitored to adjust the torques provided to the wheels of the vehicle to control the vehicle yaw rate.

A method of reconstructing a detected faulty signal. A suspension height fault is detected by a processor. A signal of the detected faulty suspension height sensor is reconstructed using indirect sensor data. The reconstructed signal is output to a controller to maintain stability.

A method of reconstructing a detected faulty signal. A roll sensor fault is detected by a processor. A signal of the detected faulty roll sensor is reconstructed using indirect sensor data. The reconstructed signal is output to a controller to maintain stability.

A method of controlling the brake system of a vehicle. The method includes receiving one or more electrical signals each indicative of a value of a respective vehicle-related parameter. The method further includes detecting that the vehicle is traveling across a slope based on the value(s) of one or more of the vehicle-related parameters. The method still further includes automatically modifying the amount of brake torque being applied to at least certain of the wheels of the vehicle in response to the detection of the vehicle traveling across a slope by increasing the amount of brake torque being applied to one or more wheels on one side of the vehicle, and decreasing the amount of brake torque being applied to one or more wheels on the other side of the vehicle.

A vehicle behavior stabilization system includes a yaw moment applying device configured to apply a yaw moment to the vehicle, a vehicle behavior stabilization control unit configured to selectively control the yaw moment applying device in such a way to stabilize a vehicle behavior according to a computed rear wheel slip angle in relation to a start threshold value and an end threshold value, and a threshold value correcting unit configured to correct the start threshold value and the end threshold value according to a change rate of the computed rear wheel slip angle and/or a change rate of a computed vehicle body slip angle.

In this brake control device for a motorcycle, a deceleration threshold value calculation unit limits target wheel deceleration to a threshold value or less on the basis of a bank angle estimated by a bank angle calculation unit. Thus, the behavior of the vehicle body during turning of the motorcycle can be made more stable so as not to cause discomfort to a driver.

A method in a vehicle for estimating vehicle motion state during a vehicle maneuver, comprising; obtaining a trigger signal indicating an onset of the vehicle maneuver, selecting a sub-set of wheels on the vehicle to be in a free-rolling condition, measuring one or more parameters related to revolution of the sub-set of wheels in free-rolling condition, and estimating the vehicle motion state based on the measured parameters.
