Methods and apparatus for estimating and compensating for wind disturbance force at a tractor trailer of an autonomous vehicle
A method includes receiving, iteratively over time, sets of data including vehicle dynamics data, image data, sound data, third-party data, and wind speed sensor data, each detected at an autonomous vehicle and associated with a time period. The method also includes estimating a first wind speed and a first wind direction for each time period, in response to receiving the sets of data and based on the sets of data, via a processor of the autonomous vehicle. The method also includes iteratively modifying a lateral control and/or a longitudinal control of the autonomous vehicle based on the estimated first wind speed and the estimated first wind direction, via the processor of the autonomous vehicle and during operation of the autonomous vehicle.
Vehicle control apparatus
A vehicle control apparatus includes a generator, a brake system, first and second sensors, first and second deceleration rate setting units, and a power generation torque controller. The first deceleration rate setting unit sets, when a first control mode that decelerates a vehicle on the basis of a brake operation performed by an occupant is executed, an allowable deceleration rate upon deceleration of the vehicle on the basis of a brake operation amount. The second deceleration rate setting unit sets, when a second control mode that decelerates the vehicle on the basis of a situation ahead of the vehicle is executed, the allowable deceleration rate upon deceleration of the vehicle on the basis of a brake fluid pressure. The power generation torque controller controls power generation torque of the generator on the basis of the allowable deceleration rate that is set by the first or second deceleration rate setting unit.

VEHICLE CONTROL DEVICE, VEHICLE AND VEHICLE CONTROL METHOD
A vehicle control device includes a processor. The processor is configured to: output a torque command value related to a rotation speed of a wheel of a vehicle; specify an estimated value which is a value obtained by estimating the rotation speed of the wheel based on the torque command value; and determine a parameter based on an error between the estimated value and a measured value which is a value obtained by measuring the rotation speed of the wheel. The torque command value is determined by a feedforward control using a target value which is a value as a target of the rotation speed of the wheel and the parameter.
DRIVING FORCE CONTROL DEVICE
A driving force control device in which, when an automated driving mode is shifted to a manual driving mode, a driving force is controlled based on an override driving force characteristic specifying target acceleration according to a vehicle speed, a accelerator pedal position, and a traveling resistance to the vehicle, a longitudinal acceleration at a fully closed accelerator pedal position in the override driving force characteristic is higher than the longitudinal acceleration at the fully closed accelerator pedal position in the manual-driving-mode driving force characteristic, and an inclination of a graph representing a relationship between the accelerator pedal position and the longitudinal acceleration in the override driving force characteristic is smaller than the inclination of the graph representing the relationship between the accelerator pedal position and the longitudinal acceleration in the manual-driving-mode driving force characteristic at a same accelerator pedal position.
Trailing vehicle positioning system based on detected pressure zones
A system for controlling platooning by a following vehicle includes a main body of the following vehicle. The system further includes a pressure sensor located in or on the main body and configured to detect a pressure corresponding to a pressure wake from a leading vehicle. The system further includes an electronic control unit (ECU) located in or on the main body, coupled to the pressure sensor, and configured to determine an optimal distance from the following vehicle to the leading vehicle based on the detected pressure. The optimal distance corresponding to a distance at which drag applied to the following vehicle is reduced based on the pressure wake from the leading vehicle.
Vehicle speed control
A vehicle speed control system that carries out a method of: automatically causing application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value v_target; controlling a rate of change of speed of the vehicle by application of positive and negative torque to one or more wheels; and receiving information relating to a terrain response mode in which the vehicle is configured or an amount of drag imposed on a vehicle. The system is configured to control the rate of change of speed in dependence at least in part on the terrain response mode, the amount of drag imposed on the vehicle, or both.
METHOD FOR CONTROLLING STATE CHANGES OF A DRIVETRAIN
A method controls state changes of a drivetrain of a vehicle connecting at least one heat engine and/or one electric motor to the wheels of the vehicle via a transmission, providing the transfer of torque from the heat engine and/or from the electric motor to the wheels in one or more gear ratios. The authorization to switch from a current state to a target state depends on reducing an acceleration of the vehicle in an intermediate state causing a lower acceleration of the vehicle during the transition between the current state and the target state.
Range prediction in electric vehicles
A first method of predicting the range of an electric vehicle comprises, determining a range value during a current vehicle operating cycle using a first range model, wherein the first range model is dependent on an energy consumption rate value recorded during a previous vehicle operating cycle. A second method of predicting the range of an electric vehicle comprises, monitoring a trailer detecting means of the vehicle; and determining a first range value if the trailer detecting means detects that a trailer is attached to the vehicle.
