Information processing apparatus, vehicle, information processing method, and computer program product
According to an embodiment, an information processing apparatus includes one or more processors configured to: acquire a dynamic state related to traveling of a moving object entering an intersection; acquire intersection information indicating a configuration of the intersection; specify a reference route along which the moving object is predicted to travel at the intersection, based on the dynamic state and the intersection information; detect a speed control point that is a position included in the specified reference route; and generate a speed model representing a temporal change in a predicted speed of the moving object so that the speed at the speed control point is locally minimized, based on the dynamic state and the intersection information.
VEHICLE TRAVEL CONTROL APPARATUS
A vehicle travel control apparatus includes an actuator and an electronic control unit. The electronic control unit is configured to determine whether a driver of a vehicle is in an abnormal state where the driver loses an ability of driving the vehicle. The electronic control unit is also configured to stop the vehicle at an abnormality determination time point onward, and control a vehicle speed by using the actuator such that the vehicle speed does not become lower than a lower limit vehicle speed in a period from the abnormality determination time point to a time point when the vehicle is stopped. The lower limit vehicle speed is set in accordance with a road shape influencing timing when a driver of another vehicle traveling behind the vehicle visually recognizes the vehicle.
Vehicle control system with track temperature sensing
A work vehicle may include a load sensor, an engine, a drive train driven by the engine and a track system including at least one track. The track system is connected to the drive train. The work vehicle may further comprise a temperature sensor configured to sense a temperature and a vehicle control system configured to receive the sensed temperature and a vehicle load from the load sensor. The vehicle control system is configured to output a work speed vehicle alert based upon a combination of the temperature sensed by the temperature sensor and the vehicle load sensed by the load sensor.
Vehicle control unit (VCU) and operating method thereof
Disclosed are a vehicle control unit (VCU) and an operation method thereof that calculate a speed variation of a vehicle based on input information, predict an average speed of the vehicle based on the calculated speed variation, generate a first speed profile based on the predicted average speed, and generate a second speed profile by applying speed noise information to the first speed profile.
Ground vehicle control techniques
Ground vehicle control techniques adapted to reduce energy consumption, braking, shifting, travel distance, travel time, and or the like. The techniques can generate a target speed window and a target vehicle performance plan for controlling operation of a ground vehicle along a current and one or more upcoming segments of a roadway responsive to the dynamic driving environment.
Using Discomfort For Speed Planning In Responding To Tailgating Vehicles For Autonomous Vehicles
Aspects of the disclosure relate to controlling a first vehicle in an autonomous driving mode. While doing so, a second vehicle may be identified. This vehicle may be determined to be a tailgating vehicle. An initial allowable discomfort value representing expected discomfort of an occupant of the first vehicle and expected discomfort of an occupant of the second vehicle may be identified. Determining a speed profile for a future trajectory of the first vehicle that meets the value may be attempted based on a set of factors corresponding to a reaction of the tailgating vehicle. When a speed profile that meets the value cannot be determined, the value may be adjusted until a speed profile that meets the value is determined. The speed profile that meets an adjusted value is used to control the first vehicle in the autonomous driving mode.
Longitudinal driver assistance system in a hybrid vehicle
A longitudinal driver assistance system, in a hybrid vehicle equipped with at least one electric drive motor, one internal combustion engine and one electronic drive control unit which actuates said motor and engine, includes: a detection system for the predictive detection of an event which, starting from an actual speed, leads to the specification of an increased setpoint speed at a specified location-dependent time, and a function unit which is configured to specify a setpoint acceleration profile to the increased setpoint speed and to output it to the drive control unit for generating a motor/engine torque which is necessary to reach the setpoint acceleration profile. The function unit is also configured to receive, when a defined condition applies, a limiting maximum possible motor/engine torque from the drive control unit, which motor/engine torque is not sufficient to reach the setpoint acceleration profile, and to specify a changed setpoint acceleration profile on the basis thereof.
DRIVING ASSIST SYSTEM
A driving assist system assists driving of a vehicle. A deceleration target includes at least one of a preceding vehicle, a mandatory stop line, a mandatory stop sign, a traffic signal, and a stop line before the traffic signal that exist ahead of the vehicle. A risk factor includes at least one of a pedestrian, a bicycle, a motorcycle, an oncoming vehicle, and a parked vehicle that exist ahead of the vehicle. The driving assist system executes: deceleration assist control that automatically decelerates the vehicle before the deceleration target; and risk avoidance control that automatically performs at least one of steering and deceleration of the vehicle so as to avoid the risk factor. When both the deceleration assist control and the risk avoidance control operate concurrently, the driving assist system notifies a driver of the vehicle of not the risk factor but the deceleration target.
METHOD AND SYSTEM FOR GENERATING VELOCITY PROFILES FOR AUTONOMOUS VEHICLES
Embodiments of the present disclosure relate to generating velocity profiles for an autonomous vehicle (101). An ECU (107) of the autonomous vehicle (101) receives road information from one or more sensors (106) associated with the autonomous vehicle (101). One or more parameters related to smooth movement of the autonomous vehicle on the road is determined from the road information. Further, a first velocity profile is produced using an AI model and a second velocity profile is produced using a hierarchical model, based on the one or more parameters. Furthermore, one of the first and the second velocity profile is selected by comparing the first and the second velocity profiles. The selected velocity profile has a lower value of velocity value compared to the other velocity profile. The selected velocity profile is provided to the autonomous vehicle (101) for navigating on the road (102) smoothly.
Effect of Multiple Rules of the Road At Different Elevation Profiles on Speed Constraints and Fuel Consumption
This invention involves the effect of multiple rules of the road at different elevation profiles on the speed constraints and therefore the overall fuel efficiency. A vehicle designed to optimize fuel consumption that is comprised of the rules of the road that determine maximum speed, minimum speed, stop signs, streetlights, and/or changes in other rules that determine the allowable speeds of the road, a localization mechanism, and an optimization engine to optimize the fuel economy by selecting a speed profile within that maintains the vehicle within the assigned range of speeds and minimizes fuel consumption. A wide variety of methods that typically are used to optimize the fuel efficiency of human drivers operating standard vehicles can also be applied towards autonomous vehicles driving at different speed constraints and with different changes in the elevation.
