Abstract: A distributed active suspension control system is provided. The control system is based on a distributed, processor-based controller that is coupled to an electronic suspension actuator. The controller processes sensor data at the distributed node, making processing decisions for the wheel actuator it is associated with. Concurrently, multiple distributed controllers on a common network communicate such that vehicle-level control (such as roll mitigation) may be achieved. Local processing at the distributed controller has the advantage of reducing latency and response time to localized sensing and events, while also reducing the processing load and cost requirements of a central node. The topology of the distributed active suspension controller contained herein has been designed to respond to fault modes with fault-safe mechanisms that prevent node-level failure from propagating to system-level fault. Systems, algorithms, and methods for accomplishing this distributed and fault-safe processing are disclosed.

Abstract: A method selects one or more power sources in a hybrid electric vehicle (HEV) at a particular moment in time for a current route to optimize energy consumption for the HEV, wherein the HEV includes one or more electric engines (EC) and one or more internal combustion engines, by first determining, in an off-line processor, a regression model that predicts a terminal cost of a state along a route from features associated with the route and the vehicle, using a computed true costs-to-go of multiple states from multitude of real or imaginary routes. In an online processor in the HEV, truncated dynamic programming is performed using the regression model to estimate a terminal cost at an end of a truncated time horizon for a current route. Then, one or more of the power sources are selected for the one or more EC and the one or more ICE based on a minimal cost-to-go of a current state.

Abstract: A central control entity controls all actuators of a chassis control system of a motor vehicle. To select a combination of actuator operations best suited for influencing the handling of the motor vehicle, the effect of a change of settings of motor vehicle actuators on the handling is predicted by an observer device configured to receive at least one sensor signal from a sensor via a signal input and, depending on the sensor signal, to determine at least one estimated value for a slip resistance of the motor vehicle. The controller is configured by operating the controller in a test motor vehicle that has a sensor for a measured variable, for which the observer device determines an estimated value. The estimated values from the controller are then compared with corresponding measured values.

A wheel information acquiring unit acquires the positional information of a wheel or wheels of the vehicle-in-front in the image taken by the camera.
