    摘要: A method (600) for exiting a sailing mode of a vehicle (100) is described. The vehicle (100) comprises a clutch unit (103) which is disengaged in order to decouple a driving shaft (102) of the vehicle (100) from a driven shaft (105) of the vehicle (100), when the vehicle (100) is operated in the sailing mode. The method (600) comprises predicting (601) that a trigger for an exit of the sailing mode will occur, and initiating (602) the preparation of the clutch unit (103) for engagement, subject to predicting that a trigger for the exit of the sailing mode will occur. Furthermore, the method (600) comprises detecting (603) a trigger for the exit of the sailing mode, and adapting (604) a shaft speed (230) of the driving shaft (102), subject to detecting a trigger for the exit of the sailing mode. In addition, the method (600) comprises engaging (605) the clutch unit (103), subject to preparing the clutch unit (103) for engagement and subject to adapting the shaft speed (130), in order to exit the sailing mode.

    摘要: A method and a system for choosing a transmission mode in a vehicle over the course of a road section, wherein the vehicle has applied coasting prior to this road section and wherein a highest permitted speed vmax is defined for the road section, below which an actual speed for the vehicle should be kept. A simulation of a future speed profile vsim—Gear for a possible gear position for a gearbox in the vehicle is conducted on the basis of a road slope obtained from map data in combination with vehicle positioning information and wherein the simulation simulates, when the road section lies ahead of the vehicle, an actual speed for the vehicle over the course of the road section. Next, an evaluation is carried out of whether a suspension of the coasting in favor of the possible gear position is recommended, wherein the possible gear position is deemed recommendable if a highest value vsim—Gear—max for the future speed profile exceeds the highest permitted speed vmax. The evaluation is then utilized in the choice of transmission mode.

    摘要: A vehicle engine automatic control device has a brake pedal operation amount detecting unit that detects an amount of brake pedal operation by a driver, a negative pressure-based force multiplying unit that multiplies a force, with which a brake is operated, using an intake negative pressure of an engine, a negative pressure detecting unit that detects a negative pressure of the negative pressure-based force multiplying unit, and a coast stop control unit that stops the engine when the amount of brake pedal operation that is detected is equal to or greater than a first operation amount threshold during coast drive, and re-starts the engine when the negative pressure that is detected falls below a first negative pressure threshold after the engine stops.

    摘要: A velocity profile can be used in conjunction with vehicle operating condition data to determine a gear shift schedule that mitigates the amount of service brake effort required to slow a vehicle by making optimal use of engine speed, friction and engine brakes. The gear shift point drives the engine to a higher operating speed and greater frictional torque, slowing the vehicle, which can then coast to a desired speed. The gear shift point can be timed to minimize fuel consumption during the maneuver. Thus, a vehicle downshift event is created based on the transmission gear recommendation. The benefit is increased freight efficiency in transporting cargo from source to destination by minimizing fuel consumption and maintaining drivability.
