An integrated control system includes a main control system (accelerator) controlling a driving system, a main control system (brake) controlling a brake system, and a main control system (steering) controlling a steering system, an adviser unit generating and providing information to be used at each control system based on environmental information around the vehicle or information related to a driver, an agent unit generating and providing information to be used at each of the main control systems to cause the vehicle to realize a predetermined behavior, and a supporter unit generating and providing information to be used at each of the main control systems based on the current dynamic state of the vehicle.

Vehicle integrated control system

In one embodiment, a system and method are provided for detecting a slip condition between a vehicle tire and a road surface, processing contemporaneous vehicle data, such as torque or brake pressure applied, to determine a force of friction, and calculating a coefficient of friction. The coefficient of friction and location of the slip are broadcast to other vehicles driving in the proximity of the slip. The broadcasts may be utilized to notify drivers of slippery driving conditions at or ahead of the vehicle, and/or to limit torque and braking pressure applied to vehicle wheels to enhance traction and avoid slip.

A powertrain includes an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and an electric machine to selectively transmit mechanical power to an output member. Powertrain operation includes monitoring operator inputs, and determining input speeds and changes in input speeds for the internal combustion engine and the electric machine. The input speeds are compared to threshold input speeds, and the changes in input speeds are compared to threshold changes in input speeds. Input torques of the internal combustion engine and the electric machine are reduced when any one of the input speeds and changes in input speeds exceeds the corresponding threshold.

Emission management for a hybrid locomotive

A method for providing traction control when starting off a vehicle on a road surface having different adhesive friction values between the right and left sides of the vehicle, the driven low-μ wheel being regulated to a specified setpoint slip pre-control value by a braking intervention if spinning occurs. In order to improve driving comfort, the engine speed is adjusted to the particular standing start conditions. To this end, the engine torque actually required for starting off is determined as soon as the vehicle is set in motion and has exceeded a specified speed threshold, and the engine speed actually required for starting off under the given conditions is determined from this. From this in turn, a new, corrected setpoint slip value is calculated and the setpoint slip is abruptly reduced or increased from the setpoint slip pre-control value to the newly calculated, corrected setpoint slip value.

A system for monitoring the vehicle dynamics of a motor vehicle with at least two wheels (12), comprising at least one wheel-force sensor arrangement (10) for a wheel (12), which records at least one wheel-force component, essentially acting between the driving surface and the wheel contact surface for the corresponding wheel (12) and transmits a signal (Si, Sa), representative of the wheel-force component and an evaluation device (14) which processes the signal (Si, Sa), representing the wheel-force component of the wheel (12). According to the invention, the evaluation device (14) determines a yawing moment for the vehicle as per the result of the processing. The invention further relates to a corresponding method.

A vehicle traction control system having capabilities for braking intervention and coefficient of friction detection is provided, a slipping wheel being braked by braking intervention if a slip threshold is exceeded. In order to improve the lateral stability of the vehicle when cornering on road surfaces having a low coefficient of friction, the slip threshold for the drive wheel on the outside of the curve is reduced independently of that of the drive wheel on the inside of the curve and is set to a lower value than that for the wheel on the inside of the curve.

The control system computers the maximum torque transmitted by each wheel onto the road surface and thereby calculates the actual road grip. The torque of the engine is adjusted to provide max. torque transfer for each driving wheel. The actual torque set is dependant on the road grip and on the speed of the vehicle. The system corrects for different types of tyres e.g. winter and summer types, and can operate with mixed tyres. Steering control and cornering are also taken into account.

A system for determining the height of the center of gravity of a vehicle includes an arrangement configured to determine a difference between wheel contact forces, an arrangement configured to determine a transverse acceleration, an arrangement configured to determine comparison values which compares the change in the difference between wheel contact forces with the change in the transverse acceleration, and an arrangement configured to evaluate a roll model which determines the height of the center of gravity from the comparison values. Furthermore, a corresponding method is for determining the height of the center of gravity of a vehicle.
