    摘要: A power distribution control system of a vehicle includes a driving information provider for collecting and providing information required for power distribution control of an engine and a motor in the vehicle; a communication unit for transmitting the information provided by the driving information provider from the vehicle; a cloud server outside the vehicle for selecting and transmitting optimal power distribution control logic data corresponding to a driving situation of the vehicle based on the information provided through the communication unit from the vehicle; and a vehicle controller for performing power distribution control of the engine and the motor based on real-time driving state variable information of the vehicle using the optimal power distribution control logic data received through the communication unit by the vehicle from the cloud server.

    摘要: Fuel injection of a hybrid electric vehicle including an engine and a transmission may be controlled by a method including, determining to release coasting of the hybrid electric vehicle based on a brake pedal operation, determining whether a fuel injection suspending condition is satisfied based on vehicle running state data, suspending fuel injection when the vehicle running state data satisfies the fuel injection suspending condition, performing an engagement control of the transmission while the fuel injection is suspended, determining whether a fuel injection suspension release condition is satisfied, determining whether the engine and the transmission are directly coupled when the fuel injection suspension release condition is satisfied, and initiating fuel injection of the engine when the engine and the transmission are directly coupled.

    摘要: A method for operating a motor vehicle including a drive mechanism having at least a first drive unit and at least a second drive unit is provided. The method includes providing a drive torque directed at the driving of the motor vehicle in a first setting of the drive mechanism only by means of the second drive unit and in a second setting by means of both drive units, wherein upon exceeding a start-up threshold value by a demanded preset power there is a switching from the first setting to the second setting, and upon falling below a shut-off threshold value by the demanded preset power there is a switching from the second setting to the first setting. It is provided that the start-up threshold value and/or the shut-off threshold value is determined in dependence on a driving resistance of the motor vehicle and/or a vehicle weight of the motor vehicle. A motor vehicle employing the method is also provided.

    摘要: A driving system includes an engine an engine, a motor generator, a gear mechanism, and a controller. The gear mechanism couples the engine and the motor generator to each other. The gear mechanism includes first and second gears. The first and second gears are configured to be supplied with first driving torque from the engine and second driving torque from the motor generator, respectively. The second gear meshes with the first gear. The controller is configured to perform torque control of the engine to make a rate of variation in the first driving torque at the first gear at a time when the following conditional expression (1) is satisfied smaller than that at a time when the following conditional expression (1) is not satisfied. |T2−T1|

    摘要: A vehicle comprising an internal combustion engine, a preceding vehicle information acquiring device for acquiring preceding vehicle information relating to a preceding vehicle, including a parameter relating to a distance between vehicles which becomes greater the wider the distance between a host vehicle and the preceding vehicle, and an electronic control unit for controlling the internal combustion engine, in which, the electronic control unit is configured to initiate an idle reduction mode where the internal combustion engine is made to automatically stop when a preset engine stop condition stands and to continue the idle reduction mode if the preceding vehicle is decelerating or has stopped and to make the internal combustion engine automatically restart if the preceding vehicle is accelerating or is running at an equal speed when the parameter becomes a first predetermined value or more during the idle reduction mode.

    摘要: A method is provided to control a hybrid powertrain to achieve a desired engine speed in a combustion engine, said powertrain comprising: a gearbox with input and output shafts with the combustion engine connected to the input shaft; a first planetary gear connected to the input shaft and a first main shaft; a second planetary gear connected to the first planetary gear and a second main shaft; first and second electrical machines respectfully connected to the first and second planetary gears; first gear pair connected with the first main shaft; and second gear pair connected with the second main shaft. The method comprises a) ensuring that two rotatable components in the first planetary gear are connected; b) ensuring that all rotatable components in the second planetary gear are disconnected; c) ensuring that a gear is engaged in the first gear pair, d) ensuring that the second gear pair is disconnected; e) controlling the second electrical machine so that a desired torque is achieved in the output shaft; f) controlling the combustion engine to a desired engine speed; and g) controlling the first electrical machine so that a desired total power consumption for the first and the second electrical machines is achieved.
