Power steering system and a method of operating same

A method for controlling a power steering system utilizes a vehicle having a motor, a controller coupled to the motor, and a steering assembly. The method includes detecting a steering rate using the controller. A base level steering damping is computed using the steering rate. At least one approximate vehicle acceleration is determined. A steering torque of the steering assembly is sensed through a torque sensor configured to sense the steering torque of the steering assembly. Moreover, a user torque is determined using the torque sensor. A damping boost is computed using the user torque and the at least one approximate vehicle acceleration. A final steering damping gain is determined using the base level steering damping and the damping boost. The final steering damping gain is applied to the steering assembly to minimize unwanted feedback to the steering assembly.

Method for determining the drive train sensitivity of a drive train of a motor vehicle

A method for determines the drive train sensitivity of a drive train of a motor vehicle. A vehicle body is placed in longitudinal oscillations in the direction of travel and a parameter for the drive train sensitivity is determined as a function of the determined longitudinal accelerations of the vehicle body and the resultant angular accelerations of a transmission input shaft of a transmission of the motor vehicle.

The battery modules are respectively mounted at the cross frames in the same position and arranged in plural rows adjacently to a vehicle width direction such that a direction of the above-described longitudinal dimension is substantially parallel to a vehicle longitudinal direction, and mounting rigidity of the battery modules stored in a first storage area is set to be different from that of the battery modules stored in second and third storage areas.

Torque distribution method for vehicle

In a torque distribution method for a vehicle, torque is optimally distributed to front and rear wheels of a vehicle by reflecting pitch motion characteristics and longitudinal load movement information of the vehicle in real time. The repetition of wheel slip and the degradation of wheel slip control performance caused by the pitch motion are reduced. The longitudinal load movement of the vehicle is reduced.

METHOD FOR ASCERTAINING VEHICLE CHARACTERISTIC VARIABLES

A method for determining vehicle characteristic variables of a motor vehicle. The motor vehicle has active dampers which can set adjusting forces at the respective wheel suspensions in order to be able to raise and/or lower the body of the motor vehicle and which can also measure the acting forces. Specific predefined adjusting forces of the active dampers are imparted in order to ascertain vehicle characteristic variables from the resulting adjustment and the resulting measured forces.

Battery unit mounting structure of electric vehicle
