Steering control system
A steering control system for a vehicle that considers the limitations of at least one of the vehicle and the environment is contemplated. The steering control system can receive a vehicle characteristic, an environmental condition, a desired amount of turning, and a desired velocity of the vehicle. Based on some, or all of these parameters, the steering control system can determine at least one of a wheel torque, a wheel angle, a wheel camber, and a wheel suspension for a desired vehicle path to enhance vehicle performance.
VEHICLE CONTROL SYSTEM, VEHICLE CONTROL METHOD, AND VEHICLE CONTROL PROGRAM
A vehicle control system includes: a recognizer that recognizes a distribution state of obstacles in an advancement direction of a vehicle; a trajectory determiner that determines a target trajectory for each vehicle wheel of the vehicle on the basis of the distribution state of the obstacles recognized by the recognizer; and an automated driving controller that executes automated driving of the vehicle along the target trajectory determined by the trajectory determiner.
VEHICLE CONTROL DEVICE
A vehicle control device includes: a control portion that makes, of a plurality of shock absorbers included in a vehicle, a first damping force of at least one shock absorber that is located on a first direction side on which acceleration acts in a longitudinal direction of the vehicle larger than a second damping force of at least one shock absorber of the plurality of shock absorbers that is located on a second direction side opposite to the first direction in the longitudinal direction of the vehicle before acceleration acting on the vehicle is detected by an acceleration sensor due to acceleration or deceleration of the vehicle.
Determination of roll angle and bank angle with suspension displacement data
A device includes a body operatively connected to a plurality of wheels, with the plurality of wheels being positioned relative to a banked surface defining a bank angle (). A suspension system includes at least one suspension sensor configured to provide suspension displacement data. A controller is in communication with the at least one suspension sensor and has a processor and tangible, non-transitory memory on which is recorded instructions. The controller is configured to obtain the suspension displacement data and determine a roll angle () based at least partially on the suspension displacement data. The bank angle () is determined based at least partially on the roll angle (), a yaw rate (r), a longitudinal velocity (V.sub.x) and a plurality of predetermined parameters. Operation of the device is controlled based partly on at least one of the roll angle () and the bank angle ().
Logical configuration of vehicle control systems based on driver profiles
Apparatuses, systems, methods, and computer-readable media are provided for the logical configuration of vehicle control systems based on driver profiles. A vehicle control computer may identify driving behavior of a driver of a vehicle through vehicle operation data provided by one or more of vehicle sensors, a telematics device, and a mobile device. Based on the driving behavior, the vehicle control computer may develop a first driving profile for the driver of the vehicle. The vehicle control computer transmit the first driving profile to a remote server storing driving profiles of a plurality of users. The vehicle control computer may download a second driving profile associated with a different driver from the remote server. The vehicle control computer may configure vehicle operations based off of the second driving profile associated with the different driver and may actuate vehicle operation based on the configuration.
TIRE STIFFNESS ESTIMATION AND ROAD FRICTION ESTIMATION
The disclosed invention makes use of slip related values to calculate friction related values and tire stiffness related values and feeds back an estimated tire stiffness relates value or a calculated friction related as a basis for further calculations. In particular, the disclosure relates to methods, apparatuses and computer program products to achieve the mentioned objective.
CENTER-OF-MASS HEIGHT ESTIMATION DEVICE
A center-of-mass height estimation device includes a roll moment calculation unit for calculating roll moment of a sprung portion in a vehicle on the basis of bearing capacities of left and right suspensions provided on the vehicle, a lateral acceleration measurement unit for measuring lateral acceleration, which is acceleration in a width direction of the vehicle, a mass measurement unit for measuring mass of the sprung portion, a transfer function calculation unit for calculating a transfer function of the roll moment with respect to the lateral acceleration, and a center-of-mass height calculation unit for dividing the gain of the transfer function by the mass of the sprung portion to calculate a height from a roll center of the vehicle to a center of mass of the sprung portion.
Methods and apparatus to estimate a suspension displacement
Methods, apparatus, systems and articles of manufacture are disclosed for estimating a suspension displacement. An example apparatus includes a suspension motion determiner module programmed to output a signal to a first suspension assembly of a vehicle based on a first deflection of the first suspension assembly, the first deflection calculated based on a calculation and a second deflection of a second suspension assembly of the vehicle, the calculation selected based on whether the vehicle is utilized in a first mode or a second mode.
VEHICLE AND METHOD OF CONTROLLING THE SAME
A vehicle includes: recognizing a forward vehicle in response to the processing of image data captured by an image sensor disposed at the vehicle so as to have a field of view of the outside of the vehicle; obtaining a distance from the forward vehicle in response to the processing of detecting data captured by a radar disposed at the vehicle so as to have a detecting area of the outside of the vehicle; obtaining a change amount of vertical movement of the forward vehicle in the image data in response to the distance from the forward vehicle that is equal to or less than a reference distance; obtaining a height of an obstacle on a road surface corresponding to the change amount; obtaining the height of the obstacle on the road surface in the image data in response to the distance from the forward vehicle that exceeds the reference distance; identifying a driving speed of the vehicle; identifying a reference height corresponding to the driving speed of the vehicle; and outputting deceleration guide information in response to the height of the obstacle on the road surface that is greater than or equal to the reference height.
Vehicle with interchangeable drive modules
Vehicles may be composed of a relatively few number of modules that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.
