A method of detecting a lane change of a subject vehicle (20), having a locating device (10) which uses angular resolution for locating vehicles (VEH1, VEH2, VEH3) traveling in front, and a device (44) for determining the yaw rate (ω0) of the subject vehicle. The angular velocity (ωi) of at least one vehicle traveling in front relative to the subject vehicle (20) is measured using the locating device (10), and a lane change signal (LC) indicating the lane change is formed by comparing the measured angular velocity (ωi) to the yaw rate (ω0) of the subject vehicle.

Method and arrangement for controlling a subsystem of a vehicle dependent upon a sensed level of driver inattentiveness to vehicle driving tasks. A variable characteristic is measured, on a substantially real-time basis, which correlates to the driver's inattentiveness. The level of inattentiveness is assessed based at least in part on the measurement. The performance of a subsystem of the vehicle, such as cruise control or lane keeping support, is tailored, based thereupon, to assure that behavior of the vehicle appropriately matches the driver's present level of inattentiveness. The subsystem's operation is controlled in an effort to avoid or prevent the establishment of driving conditions that become inherently more dangerous as the driver's level of inattentiveness increases.

Methods for personalized driving of autonomously driven vehicles include: (a) downloading at least a portion of a driving profile to a vehicle, wherein the vehicle is configured for autonomous driving and wherein the driving profile is associated with a specific driver; and (b) executing one or a plurality of operating instructions prescribed by the driving profile, such that the vehicle is operable in a driving style imitative of the specific driver. Apparatuses for personalized driving of autonomously driven vehicles are described.

Methods and systems are disclosed for determining sensor degradation by actively controlling an autonomous vehicle. Determining sensor degradation may include obtaining sensor readings from a sensor of an autonomous vehicle, and determining baseline state information from the obtained sensor readings. A movement characteristic of the autonomous vehicle, such as speed or position, may then be changed. The sensor may then obtain additional sensor readings, and second state information may be determined from these additional sensor readings. Expected state information may be determined from the baseline state information and the change in the movement characteristic of the autonomous vehicle. A comparison of the expected state information and the second state information may then be performed. Based on this comparison, a determination may be made as to whether the sensor has degraded.

Method for transmitting a warning signal to a driver of a driven vehicle regarding an impending collision with a moving and / or stationary object in the vicinity of the driven vehicle. The method comprises the following steps of providing the driven vehicle with means for obtaining updated data regarding, position, velocity vector and predicted moving path of the objects; selecting a series of one or more time horizons having decreasing or increasing duration; for the longest of the selected time horizons: generating a linear velocity object (LVO) and / or non-linear velocity object (NLVO) of each of the objects; selecting a sampling time interval Δt, during which an LVO and / or NLVO is generated; determining a range of feasible velocity vector changes for the driven vehicle that are attainable within a performance time interval ΔT; repeatedly providing the driver, after each Δt, with information regarding feasible velocity vector changes for the performance time interval; sensing, estimating or assuming dynamic changes parameters representing the movement of the driven vehicle within the performance time interval, and whenever required, generating a warning signal with an escalating severity level that reflects the relative imminence of collision with the objects and that corresponds to the longest time horizon; repeating the steps above, while each time generating an updated LVO and / or NLVO for a subsequent sampling time interval, until reaching another selected time horizon which is shorter than a previously selected time horizon and another selected time horizon, until collision is unavoidable.

A model predictive control apparatus includes an initial solution generation section, an abnormality handling section, and an objective function adjustment section. The abnormality handling section performs initial solution generation when it is determined that performed optimization is abnormal. The initial solution generation section generates an initial optimal value of a future time series control input in accordance with an initial objective function, without reference to a candidate value of the time series control input. The objective function adjustment section adjusts the current objective function so that the current objective function varies stepwise with time toward the normal objective function when it is determined that the current objective function is different from the normal objective function.

A method for collision avoidance using automated braking and steering comprising: determining an actual distance to an obstacle in a path of a vehicle; determining a relative velocity between the obstacle and the vehicle; determining a first distance sufficient to avoid collision by braking only; determining a second distance sufficient to avoid collision by combined braking and steering around the obstacle. The method also includes: applying braking if at least one of, the first distance exceeds the actual distance and the first distance is within a selected threshold of the actual distance. If the actual distance exceeds the second distance and a lane change is permitted, steering control to affect a lane change is applied.

A class of transporters for carrying an individual over ground having a surface that may be irregular. Various embodiments have a motorized drive, mounted to the ground-contacting module that causes operation of the transporter in an operating position that is unstable with respect to tipping when the motorized drive arrangement is not powered. Related methods are provided for determining the maximum operating speed of the transporter from measurement of battery parameters and transporter motor current and for limiting the speed of the transporter to maintain stability.
