摘要:
A reference value for controlling a vehicle's speed is obtained by: receiving a choice from two selectable driving modes, each driving mode having a unique set of settings that influence the calculation of the reference value; making a first prediction, based on an engine torque Tret that retards the vehicle as compared with conventional cruise control, and a second prediction based on an engine torque Tacc that accelerates the vehicle as compared with conventional cruise control; comparing the first and second predictions with a lower limit value and/or an upper limit value, which delineate a speed range within which the speed should be; and determining the reference value based on the mode choice and on at least one of the comparisons and said first prediction and second prediction of the speed along the horizon, such that the reference value is within the speed range.

A travel control method executed by a travel control apparatus is provided. The travel control apparatus comprises a first detector (110) configured to detect an obstacle around a subject vehicle traveling in a first lane and a second detector (110) configured to detect a second lane adjacent to the first lane. The travel control apparatus sets a first range at a target position for lane change in the second lane. The first range has a size equal to or larger than a size which the subject vehicle occupies on a road surface. The travel control apparatus detects a range in the second lane as a second range. The range in the second lane is located at a side of the subject vehicle, and the obstacle is absent in the range in the second lane. The travel control apparatus permits the subject vehicle to change lanes when the second range includes the first range. The travel control method comprises estimating whether or not another vehicle traveling in the second lane comes away from the subject vehicle on the basis of a travel state of the other vehicle and performing correction to reduce the first range or increase the second range when the other vehicle is estimated to come away from the subject vehicle.
摘要:
A method for running a vehicle (100) that includes a combustion engine (101) which can selectively be connected to a driveshaft (104, 105). When the vehicle (100) is in motion and is approaching a downgrade, determining whether the engine (101) can be disconnected from the driveshaft (104, 105) for at least a first period of time (T1), and disconnecting the driveshaft (104, 105) for at least the first period of time (T1); and the engine (101) also is switched off for the first period (T1). A system that performs the method and a vehicle that performs it are disclosed.
摘要:
A vehicle speed control apparatus (40) comprises an upper-limit determination part (41) to determine an upper-limit speed of a vehicle each time a speed limit of a road on which the vehicle is traveling changes and a vehicle speed control part (47) to control a speed of the vehicle in such a manner as to not exceed the upper-limit speed even if the vehicle's accelerator pedal depression amount would cause the speed of the vehicle to exceed the upper-limit speed, the vehicle speed control part being configured to control, until a predetermined timing, that the speed of the vehicle does not exceed the upper-limit speed, the upper-limit speed being determined before a start of the vehicle's lane change is estimated, if (i) the start of the vehicle's lane change is estimated, and (ii) a reduction in the speed limit is determined, the vehicle speed control part being configured to control, after the predetermined timing, that the speed of the vehicle does not exceed the currently determined upper-limit speed.
摘要:
A target vehicle speed generation device comprises a determination unit (30) and a correction unit (32). The determination unit (30) determines whether or not a sudden change point (P), at which acceleration changes in excess of a predetermined condition, is present in the target vehicle speed contained in the target route information of the vehicle, which is set in advance. The correction unit (32) corrects the target vehicle speed so as to eliminate the sudden change point (P), if it is determined that the sudden change point (P) is present by the determination unit (30).
摘要:
A vehicle, method, and track control system for sensing the temperature of a track and controlling the vehicle's speed based on the temperature of the track. The track temperature may be sensed by a sensor embedded in a portion of the track, such as in a drive lug, a tread bar, or portion of the carcass. The temperature of the track may also be used to alert an operator of a track temperature issue or request that the operator reduce the speed of the vehicle.
摘要:
A method is provided for controlling the speed of a vehicle that includes a drive train for driving the vehicle and a predetermined preferred speed set. The method includes determining whether or not a substantially constant speed of the vehicle is requested, if it is determined that a substantially constant speed is requested, determining whether the requested speed lies within or outside of the predetermined preferred speed set, and if it is determined that the requested speed lies outside of the predetermined speed set, automatically adjusting the speed of the vehicle to a vehicle speed that is within the predetermined speed set.

A vehicle (102) wheel assembly (100) includes a wheel (101, Fig. 1) having at least one aperture (107, Fig. 1); a closure member (110, Fig. 3) moveably mounted on the wheel; an actuator (115, Fig. 6) arranged to move the closure member (110) relative to the wheel (101); and a wireless receiver device (1 13) arranged to receive wireless control signals from a vehicle wireless transmitter (127), and to provide the control signal to the actuator (115); the actuator being arranged to move the closure member (110) to a first position wherein the closure member at least partially covers the aperture(s) (107) and/or to a second position wherein the apertures are not covered. The control signal is initiated by a vehicle cruise control system (125) being turned on (cover apertures) or off (open apertures); and, optionally, by brake (133), clutch (131), or vehicle speed (129) signals.
摘要:
In one implementation, sets of probe data are collected by probe vehicles. The probe data describes the driving characteristics of the probe vehicles. The sets of probe data are sent to a server or a mobile device for analysis. A polycurve, including a piecewise function of map data, is modified based on the probe data. The polycurve may be a spline curve for an advanced driver assistance system. The modified polycurve may be used in the advanced driver assistance system for a vehicle traveling along the same path previously traversed by the probe vehicles. Based on the polycurve modified by the probe data, a driver assistance feature is provided to the vehicle.
