Selective braking of four wheel steering vehicle
A four wheel steering vehicle (1), in which front wheels (2f) and rear wheels (2r) can be steered in response to a steering input from a steering wheel (11), includes a rear wheel steering control unit (50) that variably controls a rear wheel steering device such that the rear wheels are steered in a prescribed relation to a steered angle of the front wheels. When the steering input is determined while the front wheel brake and the rear wheel brake are engaged, the rear wheel steering control unit disengages the rear wheel brake and steers the rear wheels. When the fore and aft inclination angle detected by an inclination sensor (40) provided on the vehicle is greater than a threshold value, the rear wheel steering control unit prohibits a steering of the rear wheels and keeps the rear wheel brake engaged even if the steering input is determined.
System and Method for Controlling a Vehicle Steering System
A system for control of a steering system of a vehicle, mechanically coupled to the wheels and including an actuator for applying a force or a torque to the steering system. A force or torque can be superimposed on a force or torque originating from the wheels. The system includes a detection unit disposed on the vehicle and configured for anticipatorily detecting at least one surface condition of a surface section located ahead of the vehicle in the direction of vehicle travel and subsequently driven on by the vehicle. The system including a data processing unit disposed on the vehicle and connected to and communicating with the detection unit. The data processing unit configured for generating control signals for controlling an actuator of the steering system based on the detected surface condition.
VEHICLE CONTROL SYSTEM, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL PROGRAM
A vehicle control system includes an automated driving controller configured to execute automated driving of a vehicle by automatically performing at least one of speed control and steering control of the vehicle, an operation reception section configured to receive an operation to switch a shift position of the vehicle, and an operation controller configured to limit reception, by the operation reception section, of the operation to switch the shift position while the automated driving is being executed by the automated driving controller.
Vehicle adapted for autonomous driving and a method for detecting obstructing objects
The present disclosure relates to a vehicle adapted for autonomous driving, such as an autonomous vehicle, comprising an assisting object detecting system for detecting obstructing objects to the vehicle. The object detecting system is adapted to detect an object by comparing a reference value of a selected parameter with a measured value of the selected parameter. The present disclosure also relates to a method and a computer program product for use in the vehicle.
Autonomous driving device
Disclosed is an autonomous driving device in which a threshold value for switching to manual driving which is used for switching a driving state from autonomous driving to manual driving with respect to degree to which a steering operation is carried out by a driver is calculated to be a greater value by a calculation unit when the direction of the steering operation is predicted to be a direction close to an obstacle than a threshold value when the direction of the steering operation is predicted to be a direction away from the obstacle or a threshold value when no obstacle is detected.
SYSTEMS AND METHODS FOR HANDS-ON-WHEEL DETECTION
A method hands-on-wheel detection includes receiving a handwheel angle signal from a sensor associated with a handwheel of a vehicle and generating, based on a handwheel angle indicated by the handwheel angle signal, a handwheel speed signal and a handwheel acceleration signal. The method also includes synchronizing the handwheel speed signal and the handwheel acceleration signal by generating a delayed handwheel speed signal and a delayed handwheel acceleration signal. The method also includes generating an operator torque estimation signal based on, at least, the delayed handwheel speed signal and the delayed handwheel acceleration signal. The method also includes determining whether hands of an operator of the vehicle are on the handwheel based on the operator torque estimation signal.
Vehicle control method and vehicle control device
A vehicle control method for controlling a vehicle using a vehicle control apparatus includes: a sensor configured to detect a state outside a subject vehicle; and a control device. The vehicle control method includes: executing control of recovering a travel trajectory of the subject vehicle to a target trajectory, as ordinary control, by giving a steering amount in a lateral direction with respect to a travel lane of the subject vehicle; using detection data of the sensor to determine whether or not another vehicle is traveling in an adjacent lane to the travel lane of the subject vehicle; and when determining that the other vehicle is traveling in the adjacent lane ahead of the subject vehicle, increasing a response of the steering amount to a higher response than that in the ordinary control, before the subject vehicle passes the other vehicle.
Apparatus and method to maximize vehicle functionality and fuel economy with improved drivability during engine auto stop-start operations
An auto stop-start equipped vehicle power management system includes a primary power source supplying energy to an electrical starter to crank a vehicle engine and a secondary power source coupled in parallel to the primary power source. The secondary power source supplies energy to electric loads during an engine auto stop-start operation. The electrical loads maintain vehicle subsystem functionality during the engine auto stop-start operation. The energy supplied to the electrical loads is current limited during the engine auto stop-start operation. A controllable switch decouples the secondary power source from the primary power source and starter motor during the engine auto stop-start operation. Operating parameters of the electrical loads are monitored during the engine auto stop-start operation. If a respective operating parameter threshold associated with the electrical loads is exceeded during the engine auto stop-start operation, then the vehicle engine is automatically restarted and the controllable switch is subsequently closed.
DRIVER ASSISTANT SYSTEM AND METHOD OF CONTROLLING THE SAME
Provided is a driver assistance system including an internal camera installed in a vehicle to detect whether a driver is in a drowsy driving, and configured to photograph a state of eyes of the driver to acquire drowsiness data, a first sensor installed in the vehicle to have a front-side view of the vehicle, and configured to acquire first sensor data to detect an object in the front-side view, a second sensor installed in the vehicle to have a rear-side view of the vehicle and configured to acquire second sensor data to detect an object in the rear-side view, and a controller including at least one processor configured to process the drowsiness data, the first sensor data, and the second sensor data, wherein the controller is configured to: if a result of processing the drowsiness data is that the driver has closed the driver's eyes for a predetermined time or longer, transmit a control signal to at least one of a braking device or a steering device to perform a lane change for stopping the vehicle based on a result of processing the first sensor data and the second sensor data.
