  • Publication number: 20230331097
    Abstract: The disclosure relates to a method for controlling a motion of a vehicle. The vehicle can comprise an electric powertrain having at least one drive axle with a left output shaft and a right output shaft, a power assisted steering unit, and a propulsion torque distribution unit. The propulsion torque distribution unit can be configured to allocate wheel torques of different magnitudes to the left output shaft and the right output shaft respectively. The method can comprise receiving a total longitudinal force target value, a total lateral force target value and a total yaw moment target value. The method can further comprise determining a first wheel torque for the left output shaft and a second wheel torque for the right output shaft which minimize a total power consumption of the drive axle and the power assisted steering unit.

  • Patent number: 8712641
    Abstract: A yaw stability control system for a vehicle detects and eliminates the vehicle yaw angle resulting from a body-force-disturbance and returns the vehicle to a pre disturbance heading. A yaw rate module generates a signal indicative of the vehicle yaw rate error. A yaw angle error module is triggered in response to a body-force-disturbance being detected by a body-force-disturbance detection unit, and performs integrations of the yaw rate signals to calculate a yaw angle error in order to obtain a correction of the vehicle yaw angle resulting from the body-force-disturbance. A yaw control module uses the yaw angle error in combination with the yaw rate error for a limited time period to generate yaw control signals that are sent to the vehicle brakes and/or active steering system for performing vehicle yaw stability control operations a signal to perform a body-force-disturbance yaw stability control operation for.

  • Patent number: 8620528
    Abstract: The invention relates to a method for reducing a risk of or avoiding a roll-over event of a vehicle, having means of an electronic controllable steering system and an electronic control unit. The electronic control unit identifies the occurrence of the roll-over risk, such that control means generate a signal in order to steer the road wheels more into the direction in which the vehicle is tending to roll-over.

  • Patent number: 8565993
    Abstract: An enhanced stability control system (200) for a vehicle includes a vehicle status sensor that generates a sensor signal. A driver input sensor that generates an input signal. A controller (214) may disable normal yaw stability control operation and enable body-force-disturbance (BFD) yaw stability control (YSC) operation, which includes at least partially reducing response functions of the normal yaw stability control associated with the input signal, in response to the sensor signal and performing BFD-YSC functions to achieve desired control performance upon the detection of BFD reception. The controller (214) may also or alternatively compare the sensor signal to a threshold and detect an improperly functioning/inoperative vehicle status sensor. The controller (214) disregards information associated with the improperly functioning/inoperative vehicle status sensor, and continues to perform enhanced yaw stability control operations.

  • Patent number: 8073608
    Abstract: The present invention relates to a yaw stability control system for a vehicle using a steering system and a method of controlling by detecting the occurrence of understeer, determining the degree of understeer after the occurrence of understeer is detected determining if the determined degree of understeer exceeds a threshold value, saving the steering wheel torque value and steering wheel angle value when determined that a calculated drop in steering wheel torque exceeds the threshold value, calculating a guidance torque, a driver-intended steering wheel angle, and updating the steering wheel angle at the start of the guidance torque calculation, applying the guidance torque to the steering of the vehicle, and using the driver-intended steering wheel angle for yaw stability control.
