Vehicle control system
A vehicle control system includes at least one sensor and a power supply control system. The sensor is on board a vehicle system and configured to generate vehicle data relating to a condition or parameter associated with the vehicle system. The power supply control system is configured to control one or more power supplies on board the vehicle system and to receive the vehicle data from the at least one sensor. The power supply control system is also configured to compare the vehicle data to one or more criteria relating to vehicle movement, and, in response to a determination that the vehicle data meets the criteria and receipt of a signal indicative of the vehicle system carrying (or being configured to carry) cargo of a predetermined material, generate a control signal to deactivate at least one of the power supplies.

Method for determining a corrected wheel radius on the basis of the measured yaw rate
A method for determining a wheel radius of a motor vehicle, including calculating a yaw rate of the motor vehicle by means of a wheel speed of at least one wheel and a predefined wheel radius. The calculated yaw rate is compared with a measured yaw rate. The wheel speed is adapted. The calculation of the yaw rate is input, of the at least one wheel by means of a correction factor, so that the calculated yaw rate is equal to the measured yaw rate. The correction factor and the predefined wheel radius or the wheel speed is multiplied. The calculation of the yaw rate is input, for the determination of a corrected wheel radius or of a corrected wheel speed.

Snapshots for Evaluating Component Operation in Autonomous Vehicles
The technology involves evaluating components of an autonomous vehicle that can be meaningfully evaluated over a single operational iteration. One or more snapshots of single iteration scenarios can be tested quickly and efficiently, either on vehicle or via a back-end system. Each snapshot corresponds to a particular point in time when a given component runs. Each snapshot contains a serialized set of inputs necessary to evaluate the particular component. These inputs comprise the minimal amount of information needed to accurately and faithfully recreate what the component did or does. Each snapshot is triggered at the particular point in time based on one or more criteria associated with either a driving scenario or a component of the vehicle during autonomous driving. A serialized snapshot may be retrieved from storage and deserialized, so that the system may evaluate the state of the component at the particular point in time.
