Apparatus, system and method for controlling vehicle
An apparatus for controlling a vehicle includes: a sensor that obtains vehicle surrounding environment information and vehicle driving information; and a controller that determines whether an engagement of an Electronic Parking Brake (EPB) is possible based on the vehicle driving information, performs control for preventing a slip based on the vehicle surrounding environment information upon determining that the engagement of the EPB is impossible, calculates a steering angle for preventing the slip, transmits the steering angle to a portable terminal, receives a steering control command from the portable terminal, and controls steering based on the received steering control command.
Ascertaining a Trajectory for a First Vehicle While Taking into Consideration the Drive Behavior of a Second Vehicle
A processor unit (3) is configured for accessing speed data of a second vehicle (18), the speed data generated by a sensor of a first vehicle (1). The processor unit is also configured for creating a driving behavior profile of the second vehicle (18) based on the speed data and making a prediction about the future driving behavior of the second vehicle (18) based on the driving behavior profile of the second vehicle (18). Moreover, the processor unit is configured for determining a trajectory for the first vehicle (1) by executing an MPC algorithm, which includes a longitudinal dynamic model of the first vehicle and a cost function, such that the cost function is minimized. The prediction about the future driving behavior of the second vehicle (18) is taken into account in the determination of the trajectory.
REGENERATIVE BRAKING CONTROL METHOD OF XEV VEHICLE BASED ON DRIVING RECOGNITION
A driving recognition-based regenerative braking control method of an xEV vehicle according to an embodiment of the present invention relates to a driving recognition-based regenerative braking control method of an xEV vehicle which optimally adjusts an amount of regenerative braking using preceding vehicle sensing and driving position information.
INFORMATION PROVISION SYSTEM, INFORMATION PROVISION METHOD, AND STORAGE MEDIUM
The present invention provides an information provision system that provides information to a driver of a straddle type vehicle, the system comprising: an acquisition unit configured to acquire information on a course of the straddle type vehicle; a specification unit configured to specify an attention portion to which attention of the driver should be paid in the course acquired by the acquisition unit; and a notification unit configured to notify the driver of the attention portion specified by the specification unit, wherein the specification unit is configured to specify the attention portion based on inclination information indicating an inclination on the course of a reference vehicle that has previously traveled on the course, and specify the attention portion based on a difference in a travel route on the course between the straddle type vehicle and a four-wheeled vehicle as the reference vehicles.
AUTOMATED VIRTUAL LAUNCH TORQUE GENERATION
Automated launch torque is provided. An automated virtual launch torque generation (AVL-TG) system may be included in a vehicle, such as a heavy duty truck, that may interoperate with an adaptive cruise control (CC) system to move the vehicle from a standstill or low speed to a CC handover speed. The AVL-TG system may determine a tip-in torque curve configured to mimic a torque curve generated by a human operator's acceleration pedal tip-in from a standstill or low speed. The tip-in torque curve may be represented by torque demand values corresponding to a dynamic pedal saturation level applied over a dynamic pedal rate. The torque demand values determined by the AVL-TG system may mimic an expected or human vehicle operator generated torque request, and may operate to successfully close the clutch and smoothly launch the vehicle from a standstill or low speed.
SYSTEMS AND METHODS FOR OPERATING AN AUTONOMOUS VEHICLE
An autonomous vehicle (AV) includes features that allows the AV to comply with applicable regulations and statues for performing safe driving operation. An example method for operating an AV includes receiving, from a sensor located on the AV, sensor data that captures a road sign located at a distance from the AV that is operating on a roadway; obtaining, from the sensor data, roadway information indicated by the road sign that corresponds to a segment of the roadway associated with the road sign that is ahead of a current position of the AV on the roadway; determining trajectory-related information for the AV for the distance that is based on the roadway information obtained from the sensor data; and causing the AV to travel in accordance with the trajectory-related information until a determination that the AV has arrived within the segment of the roadway associated with the road sign.
Systems and methods of engine stop/start control of an electrified powertrain
Systems, apparatuses, and methods disclosed provide for receiving internal information, external static information, and external dynamic information of a hybrid vehicle, and selectively enable or disable a stop/start function for the engine of the hybrid vehicle based on the internal hybrid vehicle information, external static information, and external dynamic information. The stop/start function controls selective activation and deactivation of the engine during operation of the hybrid vehicle.
Travel controller adaptive to road inclination or braking performance
A travel controller including an information acquisition part configured to acquire brake state information of a braking device of a host vehicle and an ACC-ECU configured to perform travel control, wherein the travel control includes constant speed travel control and headway travel control. The constant speed travel control is configured to control the host vehicle to travel at constant speed in accordance with a preset target vehicle speed. The headway travel control is configured to control the host vehicle to travel by following another vehicle travelling ahead so that a predetermined inter-vehicle distance in maintained with the other vehicle and the host vehicle travels in accordance with the target vehicle speed. In the ACC-ECU, when a braking performance index of the host vehicle has a “declined value”, a target acceleration of Example 1 takes a reduced value compared to the target acceleration of Comparative Example for a common distance difference.
Determining a Discrete Representation of a Roadway Section in Front of a Vehicle
A device (16) for determining a discrete representation (30) of a road section ahead of a vehicle (12) includes an input interface (22) for receiving sensor data (20) of a sensor (14) with information about the road section ahead of the vehicle, a setting unit (24) for ascertaining a control distance at which a property of the road section ahead of the vehicle that is relevant for an open-loop control of the vehicle changes based on the sensor data and for setting a support point in a discrete representation of the road section corresponding to the control distance. The setting unit is configured for setting a lower predefined second number (n2) of support points based on a predefined first number (n1) of support points. The device also includes an output interface (26) for outputting the lower predefined second number of support points to an optimizer (52) in order to determine a profile of at least one control parameter for the open-loop control of an open-loop system, a vehicle function based on the second number (n2) of support points.
METHOD OF RECONSTRUCTING A VEHICLE TRAJECTORY
A method for generating a vehicle trajectory by optimizing a performance measure J. The trajectory may include a sequence of states x=(x.sub.k).sub.k=1.sup.N of the vehicle. The optimization is subject to predefined vehicle dynamics x.sub.k+1=f(x.sub.k, u.sub.k), where u.sub.k is a control input to the vehicle, and a condition that each position of the vehicle shall be close to a reference path X.sup.r. The vehicle's position is constrained inside a variable-width corridor around the reference path. A quantity r controlling the width of the corridor is included as an additional optimization variable and the performance measure includes a penalty on the corridor width. To define the corridor, each point of the reference path may be associated with a pair of laterally spaced ellipses and requiring each vehicle position to be outside the ellipses.
